What does the IOC engine do in FortiAnalyzer?

The IOC (Indicators of Compromise) engine in FortiAnalyzer is designed to identify and analyze suspicious activities and behavioral patterns that could indicate a security threat. This includes monitoring web usage and checking for known indicators of compromise associated with malicious web pages. By focusing on suspicious web page usage, the IOC engine helps in flagging potential security incidents and threats based on established threat intelligence, enabling organizations to take appropriate actions to mitigate risks.

In contrast, the other options pertain to different functions not associated with the IOC engine. Detecting VPN connection issues, monitoring network latency, and calculating system performance metrics are important aspects of network management, but they do not specifically relate to the forensic and threat detection capabilities provided by the IOC engine in FortiAnalyzer.
