Serial-Connected BMS Security Challenges

Digital transformation is expanding the attack surface of insecure serial-connected Building Management Systems (BMS) such as HVAC systems, power controls, Elevators, alarm systems, and many other critical systems. Increased connectivity combined with increasingly sophisticated cyber threat actors means BMS are now facing significant risks to their safety and availability.

Securely Monitor Your Serial-Connected Building Management Systems

With the SerialGuard AnalytICS Platform you can now address these risks by bringing true visibility and real-time intrusion detection to serial-connected BMS. Combining a fully passive, real-time serial communications sensor with the power of a high-performance analytical and intrusion detection platform, the SerialGuard AnalytICS Platform enables you to securely monitor your high-risk assets and detect anomalies at speed.

Safeguarding Your Critical Systems at Levels 0/1

The SerialGuard AnalytICS Platform is a scalable level 0/1 network Intrusion Detection System that comprises two high-performance components:

SerialGuard®: Fully passive and fail-safe serial packet sniffer that sits in-line between  controllers (level 1) and devices (level 0) to securely capture real-time serial communications.

AnalytICS Engine: SerialGuard’s supporting software that operates as an End Point Protection (EPP), End Point Detection and Response (EDR) and Intrusion Detection System (IDS), and data validation tool.  The software enables you to baseline normal operations and create rule-based alerts to support early detection of anomalous behavior.

Reliable Operational Datasets: Builds serial datasets for advanced digital strategies such as Asset Performance Management (APM), Overall Equipment Effectiveness (OEE), and Predictive Maintenance.

Monitor Your Critical Assets and Processes Where It Matters Most

To adopt a successful ICS Defense-in-Depth strategy, you need to accurately monitor your serial-connected cyber-physical systems. With the SerialGuard AnalytICS Platform, you can securely achieve this with real-time monitoring and intrusion detection at the final phase of your cyber-physical processes.
