Check: GEN000251
SUSE Linux Enterprise Server v11 for System z STIG:
GEN000251
(in versions v1 r12 through v1 r9)
Title
The time synchronization file (such as /etc/ntp.conf) must be group-owned by root, bin, sys, or system. (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 group, unauthorized modifications could result in the failure of time synchronization.
Check Content

Fix Text
Change the group-owner of the NTP configuration file. Procedure: # chgrp root /etc/ntp.conf
