Title

The Cisco ISE must generate a log record when an endpoint fails authentication. (Cat II impact)

Discussion

Failing the Cisco ISE assessment means that an unauthorized machine has attempted to access the secure network. Without generating log records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Check Content

Verify that a log will be generated and sent when an Endpoint has a change in posture status. From the Web Admin portal: 1. Choose Administration >> System >> Logging >> Logging Categories. 2. Verify the Failed Attempts has LogCollector set as a target at a minimum. If the Failed Attempts logging category is not configured to send to the LogCollector and/or another logging target, this is a finding.

Fix Text

Configure a log to be generated and sent when an Endpoint has a change in posture status. From the Web Admin portal: 1. Choose Administration >> System >> Logging >> Logging Categories. 2. Configure the "Failed Attempts" category and the Targets field to have LogCollector selected at a minimum. (This is the default setting.) If the environment has an additional SYSLOG server, it can be selected here as well.
