OT/ICS Security for the Power Grid
Modern substations, power plants, and control centers rely on Ethernet-based communication. Especially when it comes to operational technology (OT) security, the associated interconnection introduces new security risks and can potentially result in major reputation losses for your company.
To prevent cyberattacks and mitigate their damage, it is vital to identify risks and detect cyber threats and prohibited activities in real time based on an industrial control system (ICS) security strategy. With regard to cybersecurity for utilities, the applied solutions must support security officers as well as OT engineers to ensure an efficient response to incidents. Having continuous knowledge and precise documentation of the risk level is vital for recommending the right actions early enough and maximizing availability.
Security systems in substations should work together seamlessly with security operations centers (SOC) and security incident and response management (SIEM) systems. As a base for OT risk management, a standard-compliant asset inventory of all devices communicating in the critical networks in power plants and substations is needed.
