HMI’s Can be Fooled!
Detect anomalies before they damage your critical assets. SIGA’s Parallel Reference Monitor (PRM) provides multi-level real-time monitoring, revealing otherwise undetectable Level-0 attacks
Current security methods for industrial control systems are beginning to evolve and include network-level security, some use of firewalls, unidirectional diodes and protected gateways. This vulnerability and common operational constraints lead to very limited solutions, at best. Therefore, the SCADA’s controller level, or Level 1 as it is called in the Purdue Model (e.g., PLC, RTU, etc.) can be compromised in various scenarios.
An attacker has taken control of a critical process while a perfectly normal operational status is reflected on the HMI and other levels. The attack is allowed to continue undetected because the control ...
