Security monitoring for OT (OT SOC)

Continuous monitoring and detection is one of the requirements of the NIS2 directive. Companies must implement systems for continuous monitoring and detection of security incidents. This includes the use of advanced monitoring tools to detect suspicious activity in real time.

OT monitoring requires different expertise than IT security, utilizing technologies such as IDS, endpoint agents, and log analysis, along with a deep understanding of OT processes. While IT monitoring is often automated, OT demands high precision and manual assessment in collaboration with system owners. To prevent serious consequences, accurate alerting and response are crucial. This involves both alerting and implementing measures in conjunction with OT providers. Control over devices and vulnerabilities (asset inventory) is also critical to uncover unknown devices and maintain security.
