Check: GEN000252

Solaris 10 X86 STIG: GEN000252 (in versions v2 r4 through v1 r17)

Title

The time synchronization configuration file (such as /etc/ntp.conf) must have mode 0640 or less permissive. (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

Verify the mode for the NTP configuration file is not more permissive than 0640. # ls -l /etc/inet/ntp.conf If the mode is more permissive than 0640, this is a finding.

Fix Text

Change the mode of the NTP configuration file to 0640 or less permissive. # chmod 0640 /etc/inet/ntp.conf
