Diagram 01: The SCADAfence Einstein Baseline’s Sensitivity DashboardThe Zero Trust motto is “never trust, always verify” and this is especially true when creating security controls in OT networks and devices. Many OT devices and systems are still using un-encrypted and unauthenticated protocols. However, it’s not just the devices. Too often, OT teams are not open to the idea of connecting their once-isolated systems or PLCs to the Internet, despite those systems being implemented with encryption and authentication. As more IT and OT systems are opening their gates to connect to the Internet, the need to adopt the principle of less privilege is more aligned with the expanding threat landscape. Organizations need to look at OT security solutions that can provide policy-based access for authorized users. This is the approach that only OT teams or other specific users should have access to OT environments. Simply put, only employees who need access to OT networks and devices to do their day-to-day job should have access. Enforcing access controls early on, which is based on the principle that no one should be able to connect unless authorized, will allow security teams to provide access once authorized. Each user and device access request needs to be verified and then, only if verified, the access will be granted to the authorized users. By implementing the Zero Trust security model with granular access authorization, it can guarantee organizations that the proper access is being granted in OT environments with an additional level of security. By restricting who has access to what network or device, the Zero Trust model will help minimize the attack surface of the increasing risks within an OT environment. Additionally enforcing MFA (multi-factor authentication) is another essential Zero Trust model capability for OT leaders to implement with role-based access. With MFA, access is only granted after successfully presenting two or more pieces of evidence, or factors, to an authentication mechanism. These factors will provide an additional layer of security against unauthorized access for OT environments. While the task to integrate the basic Zero Trust framework is not a simple task across complex environments like OT networks, rethinking a security approach with the Zero Trust framework is the right step in protecting critical infrastructure and OT environments. SCADAfence Offers Zero Trust Capabilities for OT Environments
Diagram 02: The SCADAfence Einstein Baseline’s Unique Zero Trust CapabilitiesSCADAfence is the only OT security vendor offering an OT network security solution that integrates with the Zero Trust model for industrial environments. The SCADAfence Platform enables users to define access-group segmentation and to enforce Zero Trust capabilities in their OT networks. Users can gain full visibility of their production networks which are designed and supported by the Zero Trust security framework. With the industry-leading Einstein baseline, the SCADAfence Platform learns an entire industrial network in less than 2 days. This includes learning all traffic patterns, asset behavior and network subnets. The Platform is able to immediately send alerts on any anomalies or deviations from the normal network behavior. When the Zero-Trust model is enabled in the Einstein baseline period, the Platform not only displays and alerts users of all the activities and devices on the network, but all network behaviors are treated as potentially malicious until further verified. As we continue to advance our leading OT security platform with more security features and capabilities, SCADAfence users continuously have more flexibility to manage their OT environments. Our latest integration of Zero Trust capabilities, will guide users with an additional level of security from the baseline stage to the ongoing security management stage and onward.
