Correlation Logs

The firewall logs a correlated event when the patterns and thresholds defined in a Correlation Object match the traffic patterns on your network. To Interpret Correlated Events and view a graphical display of the events, see Use the Compromised Hosts Widget in the ACC.
The following table summarizes the Correlation log severity levels:
Severity
Description
Critical
Confirms that a host has been compromised based on correlated events that indicate an escalation pattern. For example, a critical event is logged when a host that received a file with a malicious verdict by WildFire, exhibits the same command-and control activity that was observed in the WildFire sandbox for that malicious file.
High
Indicates that a host is very likely compromised based on a correlation between multiple threat events, such as malware detected anywhere on the network that matches the command and control activity being generated from a particular host.
Medium
Indicates that a host is likely compromised based on the detection of one or multiple suspicious events, such as repeated visits to known malicious URLs that suggests a scripted command-and-control activity.
Low
Indicates that a host is possibly compromised based on the detection of one or multiple suspicious events, such as a visit to a malicious URL or a dynamic DNS domain.
Informational
Detects an event that may be useful in aggregate for identifying suspicious activity; each event is not necessarily significant on its own.
