Tenable OT Security Log Extension for QRadar
Tenable OT Security enables operational engineers and cybersecurity personnel to gain visibility into, and control over, Industrial Control System (ICS) networks. Through its policies and alerts mechanism, Tenable OT Security generates real-time alerts that are accurate, actionable, and customized for each network and its unique needs.
Tenable OT Security detects unauthorized changes made to industrial processes in ICS networks. It can produce various alerts on changes in the configuration of controllers (PLC, DCS, IED), details, communications, and alert on a range of network attack vectors that may threaten industrial processes. Tenable OT Security also actively verifies the controllers’ configuration and alerts on changes made to them.
Tenable OT Security reports these alerts to QRadar via Syslog. For each individual policy, users can decide whether an alert should be sent to QRadar via Syslog; this offers them maximum control over which information is being sent.
