A recent analysis by JPMorganChase criticized the CVSS scoring process, finding missing context leads to misleading prioritization. When it comes to cybersecurity, patching vulnerabilities often feels like the Holy Grail. Get those CVEs patched, and you’re safe, right? Well, not exactly. As we know, patching isn’t as straightforward—or as effective—as we’d like to believe. Between limited resources, business interruptions, and the sheer volume of vulnerabilities, aiming for 100% patching of even critical and high severity findings can feel like chasing the wind.

Patching, while important, isn’t the ultimate answer to securing your environment.

The Obstacles to Patching Vulnerabilities

1. Volume of Vulnerabilities

The number of disclosed vulnerabilities continues to skyrocket each year. The National Vulnerability Database (NVD) catalogs tens of thousands of new vulnerabilities annually. How do you decide what to patch when every scanner generates a flood of critical alerts?

2. Business Continuity Concerns

Applying patches often means downtime, testing, and the risk of breaking critical systems. For organizations with legacy infrastructure, patching a production server could have unintended ripple effects that outweigh the vulnerability itself.

3. Resource Constraints

Whether it’s budget, people, or tools, cybersecurity teams are stretched thin. A limited team can’t patch everything without neglecting other critical duties like incident response, user awareness training, or threat hunting.

4. Exploit Context

Not every vulnerability is weaponized or even exploitable in your specific environment. Yet, traditional vulnerability management often treats all vulnerabilities as equally urgent, leading to patching fatigue.

Why 100% Patching Shouldn’t Be the Goal

Here’s the reality: patching every vulnerability isn’t just impractical; it’s unnecessary. Security isn’t about perfection; it’s about prioritization. You’re better off focusing on vulnerabilities that truly matter to your organization’s risk posture.

Why shouldn’t you aim for 100%?

• Not All Vulnerabilities Pose a Real Risk

A vulnerability in an unexposed system or one without a known exploit may not require immediate action. Over-focusing on low-risk vulnerabilities can leave high-impact risks unattended.

• Attackers Focus on Exploitable Opportunities

Attackers don’t care about your patch percentage—they care about the paths that lead to valuable assets. Patching systems indiscriminately can distract from understanding those paths.

• Runtime Context Matters More

Static vulnerability assessments tell you what could go wrong, but runtime context reveals what is happening. This is the key to distinguishing between theoretical risks and active threats.

How Graylog Helps: Asset-Based Risk with Runtime Context

At Graylog, we recognize the goal isn’t 100% patching—it’s 100% understanding. That’s where our asset-based risk approach comes into play. Graylog assesses a risk score based on real-world activity along with your vulnerability data to help you focus on what truly matters.

1. Runtime Activity as Necessary Context

Traditional vulnerability management is like looking at a static map—you see the terrain but not the movement. Graylog goes further by incorporating runtime activity. We help you answer questions like:

• Is the vulnerable asset being actively targeted?
• Is it communicating with known malicious IPs?
• Are unusual processes or behaviors happening on the system?

This real-time insight helps you prioritize vulnerabilities that attackers are actually exploiting.

2. What’s Happening vs. What Could Happen

Patching vulnerabilities addresses what could happen, but Graylog helps you recognize what is happening. By correlating log data, threat intelligence, and asset behavior, we surface indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs) that reveal active threats.

3. True Compromise Detection

Graylog’s focus isn’t just on potential risks but actual compromises. Our platform helps you identify and respond to incidents that have crossed the line from theoretical to real-world attacks. This allows you to spend less time chasing low-priority patches and more time addressing active threats.

Conclusion: Focus on What Matters

In cybersecurity, perfect can’t be the enemy of good. Chasing 100% patching is like locking every window in the house while the burglar walks in through the front door. Instead, focus on understanding your environment, prioritizing high-impact vulnerabilities, and recognizing true compromises.

With Graylog’s asset-based risk approach, you get the necessary context to separate the noise from the signal. By focusing on what’s happening, not just what could happen, you can align your resources to defend your organization effectively.

Graylog Introduces Advanced Data Routing to Align Costs with Data Value

HOUSTON – October 21, 2024 — Graylog, a leader in Threat Detection, Investigation, and Response (TDIR), today unveiled significant security advancements to drive smarter, faster, and more cost-efficient security operations. The company’s latest capabilities include advanced data routing, asset-based risk scoring, and AI-generated investigation reports. 

These enhancements, and many others in the Fall 2024 release, help organizations realign their time and financial investment with security objectives, empowering security teams to confidently reduce risk. With a detailed understanding of the threat landscape at both user and system levels, Graylog enables organizations to make more informed decisions about their security posture and respond more effectively to potential threats.

Exclusive to Graylog is its native advanced data routing that enables practitioners to send lower-value “standby” data to inexpensive storage before it is indexed by Graylog. Standby data is available for retrieval into Graylog for future incident investigations. This classification shifts the typical SIEM license model to more accurately align with the overall value of the data. Security and IT operations teams can now invest time and money in the value of the data sent, processed, and stored while minimizing the number of technology solutions managed.

“A challenge with SIEMs has been the need to bring in all the data from log sources as if all the log messages are of equal value,” said Seth Goldhammer, vice president of product management at Graylog. “Of course, if a log message is dropped, it is gone forever. Our new data routing removes this compromise, allowing practitioners to bring in all the data and only pay for the log messages delivering value.” 

Graylog’s asset-based risk modeling finds related security events across attack surfaces and prioritizes what should be investigated with context such as vulnerability state, variance, and API risk. Instead of thousands of daily alerts requiring individual triage and investigation, Graylog prioritizes the high-risk users and systems for security analysts, grouping together multiple alerts and context to expedite the investigation. 

Graylog’s Fall 2024 release includes a timeline visualization of events and leverages GenAI to summarize these details, including impact analysis, into an incident response report to further aid with those investigations and save analyst time.

To learn more about these new capabilities, attend Graylog’s free virtual user conference, Graylog GO, which will be held Oct. 23 – 24.

“Aren’t you a little short for a Stormtrooper?” In this iconic Star Wars moment, Princess Leia lazily responds to Luke Skywalker, disguised as one of her Stormtrooper captors and using authentication information to open her cell.

In other words, Star Wars acts as an analogy for a cross-site request forgery (CSRF) attack. In a CSRF attack, malicious actors use social engineering so that end-users will give them a way to “hide” in their authenticated session. Disguised as the victim, the attackers can make changes and engage in transactions based on the account’s permissions.

With a cross-site request forgery cheat sheet, you can learn the basic principles underlying these attacks and some best mitigation practices.

What is Cross-Site Request Forgery (CSRF)?

A cross-site request forgery (CSRF) attack involves inheriting the victim’s identity and privileges so that the attacker can perform actions within the site. Typically, browser requests include credential information, like a user’s:

• Session cookie
• IP address
• Windows domain credentials

After a user authenticates into the site, the attackers target functions that allow them to make changes, like:

• Changing an email address
• Creating a new password
• Making a purchase
• Transferring funds
• Elevating privileges

The site treats these forged, authenticated requests as legitimate and authorized. The attacks focus on making changes within the site because any data requested would go to the victim.

CSRF attacks can also be called:

• XSRF
• Sear Surf attacks
• Session Riding
• Cross-Site Reference Forgery
• Hostile Linking

Three Types of CSRF Attacks

Malicious actors can deploy three types of CSRF attacks.

LOGIN CSRF Attack

In a login CSRF attack, malicious actors:

• Get the user to log into an account the threat actor controls
• Victim adds personal data to the account
• Attackers log into the account to collect data and victim activity history

Stored CSRF Flaws

Attackers can store an attack on a vulnerable site using fields that accept HTML using:

• IMG tag
• IFRAME tag

This increases the damage of the attack for two reasons:

• Victims may “trust” the compromised site.
• Victims may already be authenticated into the site.

Client-side CSRF

The client-side CSRF attack manipulates the client-side JavaScript program’s requests or parameters, sending a forged request that tricks the target site. These attacks rely on input validation issues so the server-side has no way to determine whether the request was intentional.

How does a CSRF attack work?

At a high level, attackers do two things:

• Create the malicious code
• Use social engineering to trick the victim

CSRF attacks rely on:

• Web browsers handling session-related information
• Attackers’ knowledge of web application URLs, requests, or functionality
• Application session management only using browser information
• HTML tags that provide immediate HTTP[S] resource access

By clicking on the malicious URL or script, the victim sets up the attacker’s ability to exploit:

• GET requests: Browser submits the unauthorized request.
• POST requests: Victim clicking on a link or submit button executes the action.
• HTTP methods: APIs using PUT or DELETE could have requests embedded into an exploit page, but same-origin policy restrictions in browsers can protect against these unless the website explicitly allows these requests.

How is Cross-Site Request Forgery Different from Cross-Site Scripting (XSS)?

These attacks exploit different aspects of web interactions:

• Cross-Site Request Forgery: leverages use identity to take state-changing actions without victim consent
• Cross-site scripting: inject malicious code into web pages to manipulate user input and access sensitive data

Best Practices for Mitigating CSRF Attack Risk

A successful CSRF attack exploits specific application vulnerabilities and a user’s privileges. Following some best practices, you can mitigate these risks.

Use Synchronizer Token Patterns

As the most effective mitigation, many frameworks include CSRF protection by default so you may not have to build one yourself. The server-side-generated CSRF tokens should be:

• Unique per user per session
• Secret
• Unpredictable

The server-side component verifies the token’s existence and validity, comparing it to the token in the user session and the site should reject the request without it.

The mitigation uses per-session tokens because they offer the end-user a better experience. A per-request token would be more secure by limiting the available time frame for using them. However, for every user interaction, the site would need to generate a new token.

Alternative: Signed Double-Submit Cookie Patterns

In cases where you can’t use the synchronizer token, you could substitute the easy-to-implement, stateless Double-Submit Cookie pattern. With the Signed Double-Submit Cookie, you have a secret key that only the server knows to mitigate injection risks that would compromise the victim’s session.

While the Naive Double-Submit Cookie methods may be easier to implement and scale, attackers can bypass the protection more easily through:

• Subdomain exploitation
• Man-in-the-middle (MitM) attacks

Disallow Simple Requests

Simple requests are cross-origin HTTP requests that can be sent directly from the browser to the target service without getting prior approval. If the site uses <form> tags that allow users to submit data, the application should include additional protections. Some examples of additional protections include:

• Ensuring servers or APIs do not accept text/plain content types
• Implementing custom request headers for AJAX/APIs to prevent usability issues that using a double-submit cookie would create

Implement Client-side CSRF Mitigations

Since client-side CSRF attacks bypass traditional mitigations, you should implement the following:

• Independent requests: Ensure attacker controllable inputs cannot generate asynchronous requests
• Input validation: Ensure that input formats and request parameter values only work for non-state-changing operations
• Predefined Request Data: Store safe request data in the JavaScript code

SameSite (Cookie Attribute)

The browser uses this attribute to determine whether to send cookies with cross-site requests and has three potential values:

• Strict: prevents the browser from sending the cookie to the target site in all cross-site browsing contexts that involve following a regular link
• Lax: maintains a logged-in session when the user follows an external link, but blocks high-risk request methods

Verify Origin with Standard Headers

This method examines the HTTP request header value for:

• Source origin: where it comes from
• Target origin: where it’s going to

When these match, the site accepts the request as legitimate. If they do not match, it discards the request.

Involve the User

Involving users means they have to take action that mitigates risks from unauthorized operations. Some examples include using:

• Re-authentication mechanisms
• One-time tokens

While CAPTCHA requires user interaction, it does not always differentiate user sessions. While it would make attacker success more difficult, it isn’t a suggested mitigation technique.

Graylog Security: Mitigating CSRF Risk with High Fidelity Alerts

Graylog Security provides prebuilt content that maps security events to MITRE ATT&CK so organizations can enhance their security posture. By combining Sigma rules and MITRE ATT&CK, you can create high-fidelity alerting rules that enable robust threat detection, lightning-fast investigations, and streamlined threat hunting. For example, with Graylog’s security analytics, you can monitor user activity for anomalous behavior indicating a potential security incident. By mapping this activity to the MITRE ATT&CK Framework, you can detect and investigate adversary attempts at using Valid Accounts to gain Initial Access, mitigating risk by isolating compromised accounts earlier in the attack path and reducing impact.

Graylog’s risk scoring capabilities enable you to streamline your threat detection and incident response (TDIR) by aggregating and correlating the severity of the log message and event definitions with the associated asset, reducing alert fatigue and allowing security teams to focus on high-value, high-risk issues.

Everyone remembers that one required writing class they needed to take. If you’re like a lot of other security analysts, you assumed that your job would focus on using technology, not writing research papers. However, in today’s business environment, cyber incidents are critical business events, especially as governments and agencies create more reporting requirements.

A cyber incident report is a key element for your incident response process, especially when your organization reviews activities to identify areas of improvement during the lesson’s learned phase. When implementing a structured incident response plan, you should know what an IT security incident response report is, why you need one, and what it should contain.

What Is Cyber Incident Reporting?

Cyber incident reporting involves documenting the details of incidents like:

• Cyber attacks
• Data breaches
• Unauthorized access

The IT security report typically details an incident’s timeline, including:

• Date of incident
• Attacker activities and timing
• Accounts, resources, and/or data affected
• Remediation steps taken

Cyber reporting is a critical part of the incident response process because organizations can use the documents as part of:

• Lessons learned: Assessing incident detection and response to identify areas of improvement
• Implementing controls: Developing new controls to prevent a similar incident from occurring in the future
• Notification requirements: Communicating with affected parties or others as required by law

Why Are IT Security Reports Important?

Documenting an incident’s details and notifying relevant stakeholders promptly provides various benefits.

Maintain Compliance

Most legal and regulatory frameworks require organizations to report cybersecurity incidents to various involved parties, including:

• Law enforcement
• Cybersecurity agencies
• Affected parties, like individuals or companies whose data was compromised

Laws have varying timelines for providing notification. For example, the General Data Protection Regulation (GDPR) mandates that organizations report a data breach within 72 hours. Meanwhile, under the Health Insurance Portability and Accountability Act (HIPAA), covered entities must notify affected parties within 60 days.

Failure to comply with these notification requirements can lead to fines or other penalties.

Improve Risk and Threat Awareness

A detailed cyber security incident report provides insight into potential weaknesses. By analyzing the incident’s underlying causes, security teams can improve their risk models and close security gaps. The organization can use this information to address new threats then implement new security controls to mitigate risk.

Build Trust With Clients, Customers, and Stakeholders

Transparency during data breaches builds trust with stakeholders by demonstrating professionalism and urgency. Open communication about incidents reinforces that no organization is immune to cyber threats, showcasing commitment to data protection. While the organization will remove sensitive information related to its own security, the IT security incident report provides a timeline that can act as the foundation for these communications.

Cyber Reporting Challenges

Reporting, like compliance, is a process that can become overwhelming, especially for understaffed security teams.

Gathering Information

Under the pressure of an ongoing incident, security teams need to investigate quickly. Isolation and recovery are the critical steps. They document their activities, but they have no time to organize their documentation. Once they contain the threat and recover systems, they spend time putting the puzzle pieces together.

Creating a timeline

In a perfect world, incident investigations start with the first alert that the attackers trigger. Across complex, interconnected systems, the activity that initiates an investigation may not be that first alert. Additionally, many alerts only provide a quick glimpse into a moment in time. For example, Sigma rules provide insight that an event occurred but often lack context, like previous or follow up events.

Turning data into a narrative

Alerts and ticketing system notes are simply data points. They provide insight into discrete actions. For a cybersecurity incident report, analysts need to turn these events into a narrative. For example, the system may have sent a Windows Event alert with the ID 4625, “attempt made to logon with unknown user name or bad password and failed.” However, the security analyst needs to translate that “what happened” into the “why it matters.”

Using sensitive environment data

Although large language models (LLMs) can turn raw data into a narrative, cyber incident report data contains sensitive information, including user IDs or internal identifiers. Unfortunately, feeding data into a public LLM makes that information part of the technology’s database, creating a data leak issue.

What Needs to Be in a Cyber Security Incident Report?

Since organizations use IT security reports to document and learn from incidents, reports need to include technical and non-technical information that outlines various event details.

Executive summary

The executive summary provides a clear, concise overview of the cybersecurity incident for a broad audience, highlighting:

• Key finding
