FortiView Indicators of Compromise
The Indicators of Compromise (IOC) summary shows end users with suspicious web usage compromises. It provides information such as end users’ IP addresses, last detected date, host name, OS, a Map View, and number of threats. You can drill down to view threat details.
FortiAnalyzer generates the Indicators of Compromise by checking the web filter logs of each end user against its threat database. When a threat match is found, a threat score is given to the end user. When the check is complete, FortiAnalyzer aggregates all the threat scores of an end user and gives its verdict of the end user’s overall Indicators of Compromise.
To use this Indicators of Compromise summary, you must turn on the UTM web filter of FortiGate devices. You must also subscribe your FortiManager unit to FortiGuard to keep its local threat database synchronized with the FortiGuard threat database. See Subscribing FortiManager to FortiGuard.
