Check: GEN000253

IRIX 6.5: GEN000253 (in versions v1 r1 through v1 r0.6)

Title

The time synchronization configuration file (such as /etc/config/timeslave.options) must not have an extended ACL. (Cat II impact)

Discussion

A synchronized system clock is critical for the enforcement of time-based policies and the correlation of logs and audit records with other systems. If an illicit time source is used for synchronization, the integrity of system logs and the security of the system could be compromised. If the configuration files controlling time synchronization are not protected, unauthorized modifications could result in the failure of time synchronization.

Check Content

Check for an extended ACL on the NTP configuration file. # ls -D /etc/config/timeslave.options If the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the file.
