Fix Recommendation

If required by the NAC SSP, configure an alarm 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 "Posture and Client Provisioning Audit" category and the Targets field needs 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.
