Strengthening IoT Security with Cloud-Native DHCP Listening

Enhanced IoT Fingerprinting & Security with Cloud-Native DHCP Listening

More Like the Internet of Everything

With the explosion of new devices connecting to the internet, IoT (or, the Internet of Things) really might as well be called IoE (or, the Internet of Everything.) The use cases for always-connected devices span across industries – from facilities that can now better manage energy usage according to peak customer traffic, and medical devices that can adjust medication levels in seconds, to retail warehouses that can track inventory down to the last widget. It’s undeniable that IoT has been a game-changer.

 

That’s not to say, however, that IoT does not present some unique challenges – specifically for network security professionals.

Who Are You?

The devices themselves tend to run on extremely lean operating systems, which means they don’t run typical monitoring protocols like SNMP. There’s also no possibility of installing extra software like agents. They’re designed to be easy to set up; just point them at an internet connection, which means any user can add an IoT device.

This creates an especially tough situation for IT administrators. After all, an essential part of zero trust security is knowing what is on your network, which means you need to make sure operating systems and firmware are patched and up-to-date to close the gap on any known vulnerabilities. But how can you know what’s on your network if the devices don’t report back specific identification in any way?

This problem has become so common it has a name – “Shadow IoT” – and it’s so prevalent that 80% of IT leaders found devices on their network they didn’t know about.

IoT Fingerprinting to the Rescue!

To combat this, several companies that make security tools like Network Access Control software have begun offering IoT Fingerprinting. This is a way to gather information about IoT devices like model, OS or Firmware, and manufacturer without requiring the devices to report in. While an absolute game changer for helping secure these devices, it is not without its challenges.

The biggest issue is that there is no real standard across devices – most don’t support Simple Network Management Protocol (SNMP) or Windows Management Instrumentation (WMI). Some devices support Universal Plug & Play (UnPNP) or Bonjour, but typically you only find that on consumer devices like a Roku or an AppleTV. Some Cisco devices support CDP (Cisco Discovery Protocol), but that doesn’t cover other vendors; some may use LLDP instead (Link Layer Discover Protocol) but typically you will find that only on phones, video conferencing equipment, and commercial IP surveillance cameras.

Port scanning via Nmap & TCP have more drawbacks – they scale very poorly. Also, with increased pressure on IoT manufacturers to pay more attention to security, more and more devices are being shipped with all ports turned off. And of course, the most basic firewall will raise alarms when a port scan is detected.

MAC address will get you some information, but they pose some challenges too. The first six hexadecimal digits of a MAC address are called the OUI and they identify the manufacturer. This is useful, but also not super accurate in the sense that if you find an HP device on your network, that does little to tell you what it exactly is. It also does not tell you any information about operating systems or firmware.

DHCP at first seems like a great option – when a device connects to a network, its first step is typically to request an IP from a DHCP server. During the DORA process (Discovery, Offer, Request, Acknowledge) much information is passed back and forth, including information to fingerprint the device. Many enterprise switches support a process called DHCP Gleaning, where the switch listens for DHCP requests Switchport interfaces and is then captured as a device sensor and sent along with RADIUS accounting info.

The problem here is that not all switches support DHCP Gleaning. For the ones that don’t, how do you get the information collected by the DHCP server to your network access control software to do the actual fingerprinting? Some solutions have you install an on-prem DHCP forwarder, which signs your IT team up to deal with deploying and maintaining yet another server, upgrades, patches, etc. Even worse, this separate forwarder creates overhead on your network that may impact your users and sensitive traffic.

So, all hope is lost, and there’s no reliable way to accurately fingerprint all your IoT Devices, but there’s great news coming.

Portnox’s DHCP Listener Heads to the Cloud

Keep all the magic of a cloud-based solution – vendor agnostic, no maintenance, no upgrades, no worries – AND get the most accurate fingerprinting of all your IoT devices as part of your comprehensive zero-trust solution!

You can easily configure your network devices to send the data your DHCP server already gathers throughout the course of handing out IP Addresses to the Portnox SaaS DHCP listener.

All you need to enable is a layer 3 device on the same subnet as the devices you want fingerprinted, that is NOT also acting as a DHCP server. You will need to configure the DHCP helper, which will forward this information to us. Most devices support using a DHCP helper – in fact, most devices support running multiple, so no need to sacrifice anything in your current architecture. The helper will forward DHCP and BOOTP broadcasts on directly connected subnets and relay them to the Portnox DHCP listener on port 67.

If you have bandwidth considerations, you can lay them to rest – DHCP is a very lightweight protocol, consuming less than 350 bytes per request on average. Since we are not making DHCP offers, the only bandwidth is from the clients DHCP request that is forwarded from the clients.

So let’s say you have 500 clients. A DHCP lease is typically 24 hours, with clients renewing at 12 hours. That means you’d spend 175 kilobytes of total data every 12 hours…even a 28.8 baud modem could handle that request.

We use this formula to calculate bandwidth:

(((TOTAL # OF DHCP CLIENTS X 350BYTES) X2 FOR 24 HOURS) X8 CONVERT TO BITS)/ 86400 SECONDS IN A DAY

IN EXCEL THE EQUIVALENT FORMULA WOULD READ: =(((500 *350)*2)*8)/86400

This first-of-its-kind SaaS DHCP listener is easy to set up, and opens a whole new world of accurate fingerprinting for IoT Devices – click here to get started!

Why Log4Shell Remains a Major Risk for Corporate Networks.

Log4Shell is Still Lurking.

What Does it Mean for Corporate Networks?

What is Log4Shell & What Does it Affect?

In December 2021, the Log4j vulnerability, also known as Log4Shell, was made public. Log4j is a logging utility for Java that allows developers to output log messages from their applications to various destinations, such as the console, a file, or a database. Like any software, log4j is susceptible to vulnerabilities that can be exploited by attackers. Logging tools are used by developers to keep track of activity within a certain application.

To take advantage of Log4Shell, all attackers have to do is trick the system into logging a unique piece of code. They can then take over their target’s computer and install malware or launch other types of cyber attacks.

Log4j’s handling of serialized data is one area where it might be vulnerable. An attacker may be able to insert harmful code into serialized data supplied to the log4j library in some versions of log4j. The injected code may be executed if the log4j library deserializes this data, which might provide the attacker access to the system without authorization or enable them to carry out other nefarious deeds.

A year later, the issue still posses’ great risks as was noted by an announcement by both the FBI and the Cybersecurity and Infrastructure Security Agency on a network attack by Iranians at a federal civilian executive branch agency. With the relentless rise of attacks and vulnerabilities dominates the cybersecurity landscape, organizations are coping with a compound threat: the vulnerabilities from prior years that may not have been sufficiently addressed as well as the new ones that surface every year.

How Does Log4Shell Affect Corporate Networks?

What makes the Log4j vulnerability even more dangerous is how ubiquitous the Log4j 2 library is. It can be found in large and small services as well as significant platforms like VMware and Amazon Web Services. Organizations across the industry have included Apache Log4j 2 into a variety of applications because it is one of the most used logging frameworks on the internet. This includes well-known cloud providers like Twitter and Stream as well as platforms like Apple, Google, Microsoft, and Cloudflare.

The vulnerability’s impact is amplified in particular by how simple it is to exploit. The Log4j library manages how code and data are logged by applications. The flaw gives an attacker access to a string, which they can use to fool the application into requesting and executing malicious code they have control over. Attackers can thereby remotely take control of any internet-connected service that makes use of specific versions of the Log4j library, regardless of where in the software stack it is located.

The subject is pertinent to more discussions about the software supply chain and how it is more challenging to find and fix vulnerable code since many firms do not have a complete accounting of all the software they use in their systems. However, even if a company has a record of every piece of software it has purchased or installed, those programs may still contain other software components that the end user isn’t precisely aware of and didn’t intentionally choose. Because of this intricate web of dependencies between the impacted platforms and services, patching can be a challenging and time-consuming process.

Attackers are still actively using Log4Shell everywhere they can, from criminal hackers looking for a way into targets’ systems to attackers with the support of the Chinese and Iranian governments who use the exploit in their espionage operations. Moreover, latest analysis released by Tenable Wednesday revealed that the issue still exists as of October 1, 2022, and that 72% of organizations are still exposed to Log4Shell. Some companies that first mitigated the vulnerability are included in that figure. Tenable conducted the study while gathering information from more than 500 million tests.

How can Companies Mitigate This Vulnerability?

Any company can fall victim to Log4Shell. Previous research and data analysis suggest the importance of continually assessing enterprise environments for the flaw, as well as other critical vulnerabilities.

Companies should update their own applications and infrastructure that use Log4j as well as third-party applications immediately. Corporate networks need enhanced security solutions that can immediately and automatically identify vulnerable systems and their dependencies, and help you prioritize the most critical systems to update first.

Prioritizing Java processes that are accessible via public networks and have the potential to leak critical information to malicious intruders is the most effective strategy for solving this problem. Throughout this process, it is important to keep a list of all known and suspected susceptible assets and what is being done with them.

Since malicious cyber actors may compromise an asset and then patch it to cover their tracks, it is crucial to keep track of patching. In order to determine whether a threat actor may have patched an asset, organizations should maintain a detailed record of the susceptible assets they have patched.

Even with proper record keeping, it is important to verify the success of the mitigation. Use the appropriate tools and techniques to scan the patched asset. Utilize different techniques to confirm that the mitigation was properly implemented while keeping a careful eye on the asset. Look out for updates from vendors to the asset’s software.

For information on known affected products and patches, go check CISA’s Github page the GitHub page for CISA. CISA will keep the repository updated when vendors issue patches.

Given the widespread exploitation of this vulnerability, it is also advisable to conduct hunt procedures. Organizations should assume that their assets have been compromised to simulate incident response procedures. It should involve treating assets as compromised, inspecting and monitoring accounts across your enterprise that exist on or connect to assets that use Log4j. These are among the ways that corporate networks can be protected from the vulnerability.

It goes without saying that all firewalls and intrusion detection systems should be updated. The patches could filter or block LDAP and RMI traffic attempting to reach malicious LDAP servers. It is also useful to ​implement general sanitation practices like multi-factor authentication and strict VPN policies. Finally, it was noted that a design flaw in the JNDI Lookup plugin is primarily to blame for this critical vulnerability. By disabling the Jndi Lookup class, the logger will be unable to take action based on data found in the log. JNDI is however disabled by default in version 2.16.0 of Log4j.

What is the Future for Log4Shell & Cybersecurity

Recognizing the problem is the first step in solving a complicated issue like cybersecurity vulnerabilities. Just a few years ago, security breaches were a taboo subject that was rarely addressed outside of the computer sector, and firms that had experienced them were unwilling to reveal and provide specifics. The latest round of public hacks has elevated cybersecurity to the level of board discussion for many businesses. Additionally, customers can now evaluate businesses based on how they choose to handle these incursions.

Another hopeful aspect is the fact that cybersecurity education is becoming more mainstream. Degree programs in cybersecurity are currently available from many prestigious colleges, including Stanford, MIT, and University of California, Berkeley. Similar initiatives are being made in the tech and cybersecurity sectors. There will be a record number of highly skilled professionals in the security sector. They also gain knowledge from the intrusions and weaknesses. News stories from today become case studies and precedents in the law of tomorrow.

It is also encouraging to see that vendors are building new technology with security in mind. While not all technologies will benefit from this, and the environments won’t be future-proofed, it represents a significant shift from decades of development practices. Although it will take time for these modifications to take effect, keep in mind that the choices that led to the creation of Log4Shell were made years ago.

Seeing more public-private partnerships being formed is a step in the right direction. Companies and governmental organizations are working together to exchange knowledge about vulnerabilities and incursions. Organizations are sharing technical information and more comprehensive strategic lessons learned for the good of everybody. In order to respond and address these problems more quickly and effectively, this happens at numerous levels and across a variety of teams.

These are positive moves the security sector sorely needs to take. It raises the possibility that the world will have considerably more robust and resilient cyber defenses in future.

Why Do ZTNA Solutions Fall Short When It Comes to Zero Trust?

ZTNA & Zero Trust

Zero Trust is a security architecture in which every individual, inside or outside the organization’s network, must be authenticated, authorized, and continually validated for data security configuration and posture before accessing or maintaining access to information and resources.  

Zero Trust Network Access (ZTNA) is one of the ways of implementing Zero Trust, and it is a secure network access technology architecture that allows network devices or applications to be trusted once they are secured.  

Zero trust solutions are needed to manage the complexities of modern business. However, ZTNA solutions fall short of meeting these requirements. Limitations of ZTNA include the lack of management, monitoring, and policy controls. Implementing ZTNA access does not alter an attacker’s elitism when users are accessing internal applications. 

Here are several reasons why ZTNA solutions fall short when it comes to zero trust. 

ZTNA Shortcomings

Lack of Data Protection & Security Inspection Capabilities

ZTNA lacks the enforcement of data protection policies and lacks the capability to inspect and enforce data protection policies on all devices. When a user connects to an internal application, the organization has no visibility or control over the user’s machine and any possible breaches. Additionally, ZTNA does not allow for granular control over user access and cannot be configured for cloud applications or services outside the firewall perimeter.  

ZTNA Provides Insufficient Security  

When organizations deploy ZTNA, they typically also deploy other technologies and systems, including endpoint protection. Although these are complementary technologies, they use the same infrastructure. Building the network and fully complementing ZTNA policies into the infrastructure can be costly.  

In addition, when constructing a perimeter-centric network, all other security mechanisms may not provide complete security. The network can be vulnerable to security attacks, such as zero-day vulnerabilities that cannot be predicted or impeded by any technology. 

ZTNA Follows Allow & Ignore Model

When organizations deploy ZTNA, they open the door to many access points with an unstructured network traffic flow. ZTNA access solutions are commonly based on the allow and ignore model, where all requests are allowed by default, and specific ones are excluded. Organizations can use this approach to provide the highest level of security, but this model does not provide a uniform set of access policies for all applications and users. 

Weak Security & Limited Visibility

ZTNA solutions are typically based on a standards-based approach that doesn’t consider organizational security needs. ZTNA is often built on an open infrastructure, which may not have the necessary controls to protect sensitive information. Architecture failures in the network may expose critical data, making it vulnerable to data theft. ZTNA solutions also fail to address how network traffic should be protected and protected from intrusions. 

Incomplete Security For Application Services

ZTNA is a network access technology that does not secure all application services, making it less likely to detect and stop data breaches and permission abuse. In addition, organizations can use ZTNA without implementing data security features such as encryption or tokenization. This results from the inability of ZTNA to detect and stop data theft from internal and external applications.  

Failure to Perform Security Checks

ZTNA solutions are designed based on the default model in which organizations and their users can access any application they want, regardless of when they start doing so and what ZTNA policies apply. ZTNA solutions have many features that allow users to access resources and data, and organizations cannot perform security filtering. Many organizations do not deploy perimeter-centric networks, meaning that the perimeter is not secured by traffic inside the network. 

ZTNA Solutions May Not Provide Auditing

ZTNA access solutions are commonly based on a single sign-on model that allows organizations to provide single sign-on to resources. Some organizations may be aware of this and rely on this technology as the only means of access. Organizations need visibility and auditing capabilities, including seeing who has accessed sensitive data or resources. Organizations only have visibility into what is happening outside the organization’s network but may not be aware of threats or intrusions taking place inside it. 

ZTNA Solutions Are Not Designed to Reduce Risks

ZTNA relies on a screen that authenticates users and their technologies, meaning that more than one person may use the same device or technology to access resources. Although single sign-on systems mitigate this type of risk, it may still occur and is not addressed by the end user.  

Lack of an Integrated Management System

A ZTNA access solution can be a complex architecture based on standards and scripts. The complexity of some of these technologies can make it difficult to manage security policies. Organizations need a single, integrated management system to control all networks and avoid conflicting policies. 

Problems With Mobile Access

Many organizations have deployed mobile devices, but deploying and supporting them with more than one vendor is problematic. ZTNA solutions are often based on standards that can limit mobile access and generate additional problems with mobile phones. ZTNA solutions define policies but do not manage the end-user experience. When organizations deploy ZTNA, they must also deploy complementary technologies for any mobile devices that connect to the network. 

ZTNA Solutions Do Not Provide Control for The Data

ZTNA access solutions use a single sign-on model, which means that organizations are unaware of what is happening on their network and what is being sent to external applications. This does not allow organizations to see where sensitive data is being sent and stored or how critical data may be exposed. 

ZTNA access solutions also have a capability known as “trusted paths,” which allow users to connect directly to resources rather than going through an access control mechanism. Organizations do not have control over what data is being sent to external networks, where it’s going, or if it’s secure.   

ZTNA Solutions: Insufficient for Complete Zero Trust

ZTNA has its own inherent risks and cannot prevent data loss or other intrusions, nor can it protect sensitive information wherever it may be stored in the organization.  

In conclusion, ZTNA is a complex and diverse network access technology though it doesn’t provide an integrated, holistic management system for solving many of today’s security problems facing organizations.

Why Integrated Network Security Architecture is the Future

Integrated network security architecture is the design of a network to defend against cyber attacks. It is simply securing a network by integrating different security features. It is a systematic approach to designing and implementing a set of cybersecurity measures that are synergistic and mutually supportive to one another, to provide an increased level of protection.

With an integrated network security architecture, you can integrate multiple layers of protection into one cohesive system. This includes technologies, people, processes and policies. These layers work together to provide comprehensive protection for the company’s IT resources and data. It involves selecting hardware, software and services, their configuration and deployment, and how they are managed.

The security method is often referred to as the “defense-in-depth” approach. This means that it focuses on protecting data from a variety of different angles, as opposed to using just one single method. No wonder it has proven to be the most effective means of securing your network.

The three main layers of network security architecture are:

I. The Physical Layer

This includes everything from the cables and wireless antennas to the actual devices that make up your network. It is a form of perimeter protection that shields your network from wireless interference.

II. The Data Link Layer

This is where all data passes through on its way to being transmitted over the network. By default, this poses a vulnerable pathway requiring network and data protection.

III. The Network Layer

It is also referred to as endpoint protection because it is the last layer to ensure your network’s security.

Why is Integrated Network Security Architecture Important?

The integration of network security architecture is important as it helps to protect the network against cyber threats. It effectively provides a holistic view of the entire system, which is necessary for maintaining a secure and reliable network environment.

Network security is a vital part of any organization’s IT infrastructure. It is important to have an integrated network security architecture in place to protect the organization’s data and resources. This is especially crucial for organizations or even individuals that have data that they want to protect.

Four Proven Practices In Integrated Network Security Architecture

I. Perform a Threat Assessment of Your Organization’s Networks

A threat assessment is a process of identifying the potential threats to an organization and then determining how these threats might be realized. This would help to determine what measures to take to prevent it, thereby protecting your network and data.

Therefore, during any threat assessment, the first thing to do is to identify the assets in your organization. This aims to determine what would be at the risk in an attack. By putting yourself in the shoes of an attacker, you will be able to detect the assets that need to be protected.

The next step is to determine what type of threats might be present. It is important to know what kind of technology your company uses and how it might be vulnerable. Note that the major difference between threats and vulnerability is that threats are those who would want to cause harm, while vulnerabilities are weaknesses that the threats can exploit.

The last step is to develop a response plan for preventing, detecting, and responding to threats. This includes prioritizing the threats and vulnerabilities based on their level of severity and probability of occurrence.

When it comes to integrated network security architecture, threats can be categorized in two ways:

  • Technical Threats – A technical threat is when a system or network is compromised through a computer exploit or malware that disrupts its operations. This type involves exploiting security vulnerabilities in software or hardware to gain access to data and resources. Some common examples are; hacking, malware, denial of service attacks, etc.
  • Non-Technical Threats – This takes a more hands-on approach and can consist of things like insider fraud and theft of trade secrets.

II. Conduct a Business Impact Analysis

A business impact analysis is a process that can help an organization identify its risks and impacts related to network disruptions or attacks. It also helps businesses understand the vulnerabilities they might have.

It serves as a methodology that can be used to assess the impacts of disruption that might occur in the event of a cyber attack.. The analysis should be conducted by the risk management team, with input from other stakeholders within the organization.

The main objective of this analysis is to identify and prioritize risks and impacts, as well as to understand how an event will affect different parts of the organization. Analysis should also help in understanding how much time is required for recovery after a disruption or attack.

This type of analysis helps the business make decisions to mitigate its risks and impacts for the future. If an organization fully understands what would happen if there were network disruptions or attacks on their systems, it will help them understand the precise impact it might have on their business operations. Moreover, it could also prepare them for a scenario where events could happen more frequently in the future.

III. Develop a Strategy for Handling Security Incidents

Security incidents are occurring these days at an unprecedented rate. This includes any event that can negatively impact the confidentiality, integrity, or availability of an organization’s data.

It is important to have a strategy in place for how to handle them, which includes clear priorities, responsibilities, and procedures. Below is a tested incident response plan template or incident response process that you need to emulate.

IV. Assess the Severity of the Situation

When faced with a security threat, the first step is to assess the severity of the security incident and determine whether it needs to be handled by higher-level personnel or not.

If it does, they should be notified and assigned responsibility for handling the incident. If not, then a lower-level employee should take on responsibility for handling it themselves or with assistance from someone else who is available and qualified to do so.

Your assessment should follow this pattern:

  • Think about the threats that you are likely to face.
  • Make sure that your plan is flexible enough to adapt to new threats as they emerge.
  • Consider the need for interoperability with other networks, such as your partners’ networks, suppliers’ networks and customers’ networks, when designing your network architecture.
  • Determine the level of protection needed, and how much funding is available before designing your security architecture and plan.

Consider your business needs and how much risk you are willing to take on, your when designing your security architecture and plan so that these factors can be aligned.

Contain the Damage

The second priority in handling a security incident is to contain the damage. This includes notifying those who need to know, containing the spread of any virus or malware, and preventing future incidents. Depending on the type of breach, this may include initiating a forensic investigation or contacting law enforcement.

Your containment strategy should:

  • Properly segment networks with firewalls
  • Perform vulnerability assessments
  • Implement intrusion detection systems
  • Install antivirus protection on all devices
  • Use two-factor authentication for access to data and accounts
  • Protect endpoints with endpoint security solutions
  • Ensure that servers are patched and updated regularly
  • Encrypt sensitive data that is stored on the network or devices

Prevent Similar Future Attacks

The third priority when it comes to integrated network security architecture is to identify what happened and how it happened. This includes identifying who and what data was affected by the breach, if any other systems were compromised, and how to prevent similar future attacks.

Make sure that your prevention plan encompasses the two implementations below:

  • Develop an operational plan
  • Implement controls to address identified risks in the system design, physical architecture, logical architecture designs, and operational plans.

IV. Assign IT Staff to Identified Roles & Tasks

By having a dedicated IT security team, you can effectively delegate security roles and responsibilities to ensure quick detection and mitigation of present and future security threats.

Things to Consider When Defending Against a Rogue API

Application programming interfaces (APIs) are a crucial aspect of most businesses. Its responsibility involves the transfer of information between systems within an organization or to external companies. Unfortunately, a rogue API can expose sensitive data and the organization’s internal infrastructure to misuse.

A security breach could result in the leaking of sensitive customer data such as PHI or financial data. This article will give an overview of the vulnerabilities of APIs that hackers take advantage of and how best to secure them.

What is a Rogue API?

A rogue API is an API which lacks approval or authorization by a company to provide access to its data. Instead, they get created by third-party developers who access the company’s data through a back door.

Rogue developers often do not use the same security protocols abide by the same data privacy laws as the company. Several effects of these Rogue API activities include:

  • The collection of sensitive data from a business without permission, such as customer information, financial data, or proprietary information
  • The deletion or modification of stored data on a system.
  • The corruption of important files or rendering them inaccessible.
  • Using a rogue API allows the bypass security controls on a site.
  • A damaged reputation due to financial losses.

The Importance of API Security

Access to APIs occur through public networks from any location. This makes them easily accessible to attackers and simple to reverse-engineer.

APIs functions are central to microservices architectures. They help to build client-side applications that focus on customers, employees, partners, and more. The client-side application, like a web or a mobile application, interacts with the server side via the API. Invariably, they become a natural target for cybercriminals and are very sensitive to Denial of Service (DoS) attacks.

Consequently, implementing and maintaining API security (although an exhaustive process) becomes a critical necessity. Moreover, API security practices should cover access control policies and the identification and remediation of attacks on APIs. The best way to protect data is to ensure that only approved APIs access a company’s sensitive data.

Effective Strategies to Reduce Rogue API Vulnerabilities

Here are some steps organizations can take to protect against a rogue API:

  • Use a network security solution that detects and blocks API threats.
  • Grant access to sensitive data only to those who need it.
  • Conduct constant API activity monitoring for suspicious or unauthorized activity.
  • Promptly blocking suspicious IP addresses.
  • Keep all data secure by using trusted third-party services.

Best API Security Practices Against Rogue API

Get Educated on all Security Risks

Developers need in-depth knowledge of cyber criminals’ latest techniques to penetrate a system. One strategy is to get information from trusted online sources like newsletters, malware security blogs, and security news portals.

By being up-to-date with the latest hacking trends, developers can configure their APIs and ensure they thwart the latest attacks.

Authenticate & Authorize

Businesses need to carefully control access to their API resources. First, they must carefully and comprehensively identify all related devices and users. An effective strategy involves the use of a client-side application. It has to include a token in the API call so that the service can validate the client easily.

Furthermore, standard web tokens can be used to authenticate API traffic and to define access control rules. Businesses can also use grant types to determine which users, groups, and roles need access to specific API resources. For example, a user that only needs to read a blog or post a comment should only receive permission that reflects this.

Encrypt Your Data

All data requires appropriate encryption so that only authorized users can modify and decrypt the data.

It helps to protect sensitive data and enhance the security of communication between client apps and servers. The beauty is that encrypted data prevents unauthorized entities from reading them even with gained access.

Validate the Data

Most businesses rely only on the cleansing and validation of API data from external partners. Therefore, companies must implement data cleaning and validation routines to prevent standard injection flaws and attacks.

The use of debugging tools helps to examine the API’s data flow as well as track errors and anomalies.

Identify API Vulnerabilities

One important API security best practice is to perform a risk assessment. However, you must first know the faucets of your network remain vulnerable to risk .

Overall vulnerability can be difficult pinpoint because software organizations constantly use thousands of APIs simultaneously. To succeed with API security, establish measures that eliminate vulnerabilities to mitigate risk and meet security policies.

Furthermore, the discovery of vulnerabilities requires businesses to conduct rigorous testing. A great place to begin is at the initial phase of development. After that, it becomes easy to rectify them quickly.

Limit the Sharing of Confidential Information

Sharing only necessary information is a great management best practice, which is why a client application comes in handy. It filters relevant information from the entire data record present in API responses.

A developer should remember to remove sensitive information like passwords and keys before making the API publicly available. This prevents attackers from gaining access to sensitive data or entry to the application and the core of the API.

However, releasing only relevant information is a form of lazy programming. Other consequences include slowing response times and providing hackers with more information about the API access resources.

Final Thoughts on Rogue API Defense

API gateways focus on managing and controlling API traffic. Utilizing a strong API gateway minimizes security. Additionally, a solid API gateway would let organizations validate traffic and analyze and control how the API gets utilized.

The Impacts of the Ransomware Crisis on IT Teams

It’s no secret that IT teams are on the front lines of a rapidly evolving cyber-threat landscape. The ransomware crisis is raging, with attacks escalating in frequency, magnitude, and sophistication. This has impacted IT teams in multiple ways, including increased pressure to keep pace with the latest threats, complicating existing data protection efforts, and hindering the IT team’s ability to adequately meet the end-users’ needs.

Recent research by the cyber risk management company, Axion, showed that only 30% of organizations have plans to respond to the ransomware crisis. Organizations need to take a proactive approach to the ransomware crisis in which the IT team can work together with business, security, and executive teams to develop a response plan to the ransomware crisis.

What is Ransomware?

Ransomware is a kind of malicious software (“malware”) that enters a computer system and encrypts specific files, making them inaccessible to the computer user, and demands a ransom payment to be made in a set amount of time to regain access to their files. Should a payment not be made, the ransomware can delete files on the computer and write an encrypted copy of those files to a different place, rendering them inaccessible without decryption.

The ransomware crisis serves as a major IT security concern as it threatens users’ privacy, data integrity, and business continuity.

How the Ransomware Crisis Impacts IT Teams

The ransomware crisis has various negative impacts on IT teams, including:

Decreased Productivity
During a ransomware incident, IT teams are busy working on recovery, cleanup, and investigation to deal with the ransomware attack. This increases stress levels and may harm business operations across the entire organization.

Damaged Reputation
The reputation of the IT team is also affected during the Ransomware crisis. IT teams may face negative feedback from customers, partners, and vendors because the business cannot perform tasks such as completing daily transactions and service requests.

Data Loss
IT teams that are unprepared for an attack may lose critical information and data that they can’t afford to lose. The cost of losing highly sensitive data could result in reputational damage, compliance failures, and lost business.

Overworked IT Teams
Ransomware attacks can throw IT teams into an unexpected high-pressure situation, causing high levels of stress and fatigue that compromises their health and well-being.

Security Vulnerabilities
Ransomware attacks open up security vulnerabilities in your system, which hackers can use for other attacks. The longer the system remains infected, the more potential harm hackers could do through already-opened vulnerabilities.

Cost of Investigation
IT teams face the cost of conducting a detailed investigation. This can include searching for the source of attacks, determining the extent of damage, and identifying gaps in security systems leading to such attacks.

Loss of Confidence in IT
The longer it takes to restore business operations, the more likely your internal and external audience will lose confidence in your IT team. This can damage future business and an organization’s goodwill among its public and customers.

Loss of Competitive Edge
One of the most severe impacts on IT teams during the ransomware crisis is the declining competitive edge due to the loss of mission-critical assets, intellectual property, and trade secrets. This could affect an organization’s long-term business outlook, growth strategy, and financial performance.

Preventing a Ransomware Attack

The key to preventing a ransomware attack is to have a comprehensive cybersecurity plan. It is essential to have the following measures in place to avoid such crises.

System & Data Backups
Always conduct system backups to help IT teams restore files or systems in case of ransomware attacks. It is essential to back up data regularly so critical information can be retrieved in case it gets encrypted during an attack.

Patch Management
It is essential to ensure that all systems are regularly updated with the latest security patches for optimal threat protection. Also, ensure that all security updates are immediately applied across all systems in your network.

Network Security Tools
IT teams should use several tools to help detect suspicious activities and prevent ransomware attacks through a network before they can cause harm or damage. Security tools such as antivirus, host-based intrusion detection systems, vulnerability management tools, and a web gateway can help detect suspicious IP addresses and activities before any harm is caused.

Security Audits
While conducting regular security audits is not always easy, this process can help identify potential gaps in your network, which you can close before they cause harm to your business. Security audits can also help identify measures that need to be taken to prevent such attacks.

Security Awareness Training
Security awareness programs can help identify security issues that could lead to a ransomware attack. The training sessions will help your employees learn how to identify suspicious activities in their work environment and how to report any such issues or suspicious activity as soon as it is discovered. Training can also help create awareness about ransomware attacks among your employees so that they can take the right actions when faced with such incidents.

Conduct Regular Risk Assessments
Risk assessments help identify potential risks which can lead to a ransomware attack. Conducting regular risk assessments would help identify steps that need to be taken to prevent such attacks from occurring.

The Future Outlook of the Ransomware Crisis

The Ransomware crisis has an undeniably negative impact on IT teams, which can significantly hinder the long-term performance of an organization a. The longer the system remains infected, the more damage it could cause through the already exploited vulnerabilities. Staying informed about security threats is essential so that IT teams can take timely action against such threats and prevent further losses from occurring.

How Cloud IAM Security Vulnerabilities Are Being Exploited

What is IAM Security?

IAM is an abbreviation for identity access management. Identity access management systems allow your organization to manage employee applications without checking in to each app as an administrator. IAM security solutions allow organizations to manage a variety of identities, including people, software, and hardware.

IAM Infrastructure

Over the past few years, businesses have been making the move from on-prem to cloud-based operations for their business. This has been majorly contributed by the rise of SaaS applications that have allowed businesses to increase operational efficiency through the cloud.

While this brings numerous business advantages, it has further complexified the array of required appliances and services needed to keep the business running smoothly. Many organizations often use multiple different cloud service providers across numerous different services.

This has increased infrastructure complexity, while making security management more difficult. Added to this is the fact that cloud environments constantly operate and run whenever they are. This availability allows the business to run smoothly without fail, but also leaves them vulnerable to exploitation whenever a malicious actor wants to access them.

IAM security layers have become an increasingly popular attack vector as things have moved to the cloud. Such attacks utilize phishing-acquired security tokens to a devastating degree, allowing a cybercriminal to assume any role within the network.

Cloud providers such as Amazon Web Services (AWS), Microsoft Azure and Google Cloud all have various IAM security measures when managing their platforms. Using Amazon Web Service’s IAM policies as an example, we will look at how a malicious attacker could exploit a vulnerability and assume roles.

IAM Security Roles

First, we need to understand how IAM roles come into play. Authentication tokens are assigned to each user identity in AWS. But suppose you wanted to offer network access to a third-party application, tool, or web server. Creating and maintaining users account for each service could prove quite difficult.

AWS considered this issue and created a solution known as the IAM role. A role lacks a username/password or access key, as it doesn’t pertain to a specific user. IAM roles serve as a distinct identity with assigned permissions that determine what the identity can and can’t do within AWS. When users can take on different responsibilities, other roles can be assigned to them.

IAM Security Vulnerabilities

The complexities of enterprise cloud infrastructure have increased the exploitation of IAM security vulnerabilities. Exploitation can occur in various scenarios, such as when debugging in a DevOps environment, where an administrator is provided permissions for testing. This may be forgotten after testing is completed, allowing an attacker to potentially reuse the administrator credentials to access other parts of the cloud environment.

IAM security threats might also stem from other vulnerabilities such as:

Server-Side Request Forgery (SSRF)

Assume a cyber attacker discovered a website running an unpatched application with a common server-side request forgery (SSRF) vulnerability. An SSRF vulnerability allows an attacker to force a server-side application to send HTTP queries to a random domain of the attacker’s choice.

In most cases, the webpage will display the English version via eng.php. Nevertheless, if an attacker modifies the eng.php file to refer to a another URL, the web server will comply. Since the request originated from an internal source, it will then answer if the destination of the request is from an inside resource (such as the instance metadata server).

Misconfigurations

Misconfigurations are another major cause of breaches in IAM and cloud environments, often leading to data loss or unauthorized access to cloud systems. They often arise due to a poor understanding of their complex cloud environment. Fortunately, there are various tools and methods that organizations can use to address this.

Companies should implement a solution that can identify both malicious and unintentional misconfigurations in cloud setups from all entry-points, while enabling a multi-cloud environment. Along with detecting misconfigurations, this solution should offer a means to correct them.

Cloud-Native Application Protection Platform (CNAPP)

Cloud-native application protection platforms offer a solution to common IAM vulnerabilities such as these. A CNAPP analyzes both the cloud infrastructure plane and workloads to give you a complete picture of both. Logging offers one such effective measure for mitigating IAM vulnerabilities by providing insight into who and what is active within a given network.

It is important for enterprises to gain complete visibility of their complex cloud environments to mitigate IAM security threats. Since entry to a network can be granted either directly or indirectly, graph models can be easily used to clearly illustrate the specific relationships between identities and their respective rights. Since each organization’s structure and demands are unique, the ability to leverage granular insight of this data is critical.

Cloud IAM Security: Final Thoughts

Implementing the above steps to increase and manage your network visibility, data logging, and misconfiguration detection will help mitigate cloud IAM security vulnerabilities while preventing major security breaches before they happen.

IoT Device Management & The Critical Role of NAC

Introduction 

IoT (Internet of Things) is a revolutionary technology with tremendously promising potential impact. It has grown exponentially, from industry to home, and the number of IoT devices will likely keep rising. However, this new technology also raises security concerns. As these devices become prevalent in the public sector and the home, IT specialists must be able to use them appropriately

A recent forecast shows that 27 billion internet-connected devices will be in place by 2025. As IoT technology becomes  more widespread, it is beginning to influence how individuals interact worldwide. To ensure safety for IoT devices, organizations must ensure that these devices are correctly configured and monitored.   

Network Access Control (NAC) can address these IoT management and security issues by providing foundational protection against the rise of IoT threats.  

IoT Device Management, Onboarding & NAC 

IoT device management and onboarding involves securely linking IoT devices to internal networks. Organizations can then monitor and control IoT devices while securing their networks by enrolling them.  

NAC is a foundational security tool that helps with this by significantly reducing unauthorized access to critical business assets while also remedying flaws in the device enrollment process. NAC is central in securing IT infrastructure against rogue IoT devices and other malicious threats. 

How NAC Facilitates IoT Device Management & Onboarding 

Below are some roles in which implementing NAC can help IoT devices management and onboarding:

Authentication 

IoT devices need to be authenticated before they can connect to a network to mitigate the threats such as man-in-the-middle and replay attacks. NAC helps mitigate this risk by blocking access between the user and the network until they are fully authenticated.  

Network Configuration 

NAC can also adjust the network configuration of IoT devices during onboarding. For example, if it is required for a device to connect to a specific subnet or VLAN, the NAC can automatically configure it to do so. 

Monitoring 

The security posture of IoT devices can significantly affect both the security of devices and their respective networks. It is critical to monitor the health of current devices and ensure that they are properly secured. NAC performs real-time monitoring and establishes monitoring policies. 

Event & Log Management 

NAC is responsible for gathering log and anomaly data from IoT devices. It can log various events, such as device-related information, user activity, firewall and gateway logs, reports on application and security configuration changes, etc. Users can use this data to troubleshoot problems in case of any issues arising from connected devices 

Data Management 

The collected data NAC gathers form connected IoT endpoints helps to improve the security configurations of specific devices. Moreover, NAC controls how information is exchanged between connected devices and an organization’s cloud services (i.e., IoT applications). 

Security Configuration 

NAC can be used to perform deep security configurations of IoT devices, such as determining if IoT device users are permitted to connect to the network. 

If a user is authorized, NAC can also configure IoT devices’ security settings and configurations accordingly. It can be further configured to check specific attributes, such as whether an IoT device has antivirus software installed or whether it uses particular firewall rules. 

Compliance 

Upon completion of the onboarding process, the IoT device will be validated for compliance with the organization’s security policies. NAC can help oversee corporate security compliance by requiring  updates and software patches, ensuring business services adhere to regulatory standards, and configurations adhere to the licensing policy. 

Implementing a NAC-Based IoT Device Management Solution 

In executing a NAC-based IoT device onboarding solution, NAC solutions must be available for an organization’s devices and cloud services. Users must also have access to the security control plane to configure policies for connected devices and make decisions based on them. The following steps help to implement the NAC-based IoT device onboarding solution: 

Identify IoT Devices that Require Onboarding 

NAC solutions can help organizations identify what IoT devices are connected to the network, how and when they were connected, and how their configuration changes over time. This information can be used to develop policies that optimize the secure operation of IoT devices. 

Enable IoT Devices for Onboarding 

Once the devices have been identified, it is crucial to ensure that they are onboarded securely. NAC solutions can help support this process by enforcing security policies for IoT devices and using identification services and rules to ensure that there are no exceptions. 

Enable Cloud Services for Onboarding 

The network’s security dramatically relies on the cloud applications’ security. This means that it is vital for organizations to ensure that the cloud applications are appropriately configured for security and adhere to policies. 

Apply IoT Device Management & Control Policies

Once the onboarding process has been completed and each device performs as expected, it is vital to ensure that the appropriate adjustments are made. NAC solutions can provide a way to quickly deploy security policies for IoT devices or schedule recurring tests to ensure they work as expected. 

Monitor IoT Device Health 

The network’s security depends on the health of all the connected devices – and IoT is no exception. To ensure that the security of each device is maintained, it is essential to ensure that they are operating  as expected. NAC solutions can monitor IoT device performance over time and provide specific alerts when a problem is identified in a device. 

Final Thoughts on NAC & IoT Device Management

NAC is a vital component of IoT device onboarding and is essential for an organization’s devices and cloud services. NAC can help ensure that devices are securely configured and performing as expected, while also ensuring that cloud applications are installed and configured securely.

Introducing Switch Commander – Portnox’s Free Tool For Switch Monitoring & Management

Death by a Thousand Paper Cuts – The Daily Slog

The word “hero” gets thrown around a lot, but not usually for your average Network Administrator. However, if people knew how much work it truly takes to keep your corporate network humming along (securely, of course), there would probably be a national holiday. Maybe even a parade.

While you might not get the appreciation from the general public you deserve, Portnox has your back – we’ve created a new tool called Switch Commander to make everyday network administration tasks a little bit easier. Now you have one easy-to-use UI that covers all your switches.

And the best part – this tool is FREE! No trials, no credit card needed-just download it and become the commander of all your switches.

Vendor Agnostic

With Switch Commander, all you have to do is add your switch – we support SNMP v1/v2 and v3, Telnet, SSH, and HTTP/S logins. Once you’ve added all your devices, you can do simple daily administrative tasks like assigning ports to specific VLANs or seeing the status of all ports on the switch. The awesome thing is you don’t have to worry about command syntax – if your network is a combination of several different vendors (like 81% of the users we surveyed), you won’t have to remember if it’s shutdown, disable, or no power.

Getting Started with Switch Monitoring & Management

So, now that you’ve got your switches added – what can you do?

A good place to start is the Probe command – this will download all information from the switch and show it to you in a table format (the probe results are shown in the white area on the left in the screenshot above). You can see all ports, including their associated VLAN ID, and the MAC address of what is connected to them.

The Output panel (on right-hand side of the screenshot below) will show you a detailed overview of actions performed on the switch, and the Action panel shows the OID commands executed on the switch when an action is performed. This is super helpful if you’re using an SNMP-based switch monitoring system and need to see if a particular OID is supported.

From here you can enable or disable a port and set or change the VLAN.

Least Privileged, Most Useful

Another huge advantage is that once you’ve added in your switches, you can give other IT staff access to Switch Commander without having to give them credentials to the switches themselves. The login information for each device is encrypted and stored in the Switch Commander database, which has its own separate login. Now it’s safe to have your junior admin turn ports on and off or move VLANs around without them having the keys to the whole kingdom. You can also filter results so that one switch that has 10,000 ports isn’t so cumbersome to search through.

Lookin’ Fancy!

Look, if you have to stare at a screen all day, the least you can do is make it look nice with your favorite colors, right? And maybe throw on dark mode when it feels like your eyes just need a break from super bright white backgrounds! Well, Switch Commander has several different themes and skins you can choose from, so you can customize the look and feel to how you want it without burning your retinas.
