OT Network Monitoring

Why should I implement security network monitoring on my ICS network?

Implementing security monitoring tools on OT (Operational Technology) networks is critical for organizations to proactively protect their systems and ensure the integrity and availability of industrial operations. 

• Early Detection of Cyber Threats - Real-Time-Monitoring can detect anomalous behavior, unauthorized access, or potential cyberattacks in real time. Given that OT networks often manage critical infrastructure (e.g., power plants, manufacturing processes), early detection of intrusions or abnormal activity is essential to prevent damage, theft, or disruption.
• Faster Response To Security Incidents - network monitoring can alert security teams when a potential intrusion or attack is detected. By providing real-time data, these systems help incident response teams quickly identify, isolate, and mitigate threats, preventing them from escalating further.
• Forensic Investigation: IDS logs and alerts can serve as valuable sources of information for post-incident analysis. This helps identify how the attack occurred, what vulnerabilities were exploited, and the scope of the damage.
• Regulatory Compliance - Many cyber standards or frameworks including IEC62443, CMMC, NIST CSF and others require “continuous network monitoring” as a required part of their controls.
