Check: GEN000250

SUSE Linux Enterprise Server v11 for System z STIG: GEN000250 (in versions v1 r12 through v1 r9)

Title

The time synchronization configuration file (such as /etc/ntp.conf) must be owned by root. (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 owned by a system account, unauthorized modifications could result in the failure of time synchronization.

Check Content

Check the ownership of the NTP configuration file. # ls -l /etc/ntp.conf If the owner is not root, this is a finding.

Fix Text

Change the owner of the NTP configuration file. # chown root /etc/ntp.conf
