Title

The system must not be used as a syslog server (loghost) for systems external to the enclave. (Cat II impact)

Discussion

Syslog messages are typically unencrypted and may contain sensitive information and are, therefore, restricted to the enclave.

Check Content

The syslog server's /etc/syslog.conf file must have the client(s) listed along with the logging facility. The following example is a syslog.conf entry for the syslog client machine moe.larry.com: +example.com *.* /var/adm/log/example_com.log NOTE: This will virtually always require a manual review. Ask the SA if the loghost server is collecting data for hosts outside the local enclave. If it is, this is a finding.

Fix Text

Configure hosts outside of the local enclave to not log to this system.
