Discussion

The aggregation of log data kept on a syslog server can be used to detect attacks and trigger an alert to the appropriate security personnel. The stored log data can be used to detect weaknesses in security that enable the network IA team to find and address these weaknesses before breaches can occur. Reviewing these logs, whether before or after a security breach, are important in showing whether someone is an internal employee or an outside threat.

Check Content

Check the Forescout logs periodically to ensure proper auditing functions are still enabled and have not been changed. A proper security policy performs periodic checks to help ensure the proper information is being gathered in the event of a security breach, or internal/external threat. 

If the Forescout auditing functions are disabled or have been changed, this is a finding.

Fix Text
