AIX7-00-002090 - AIX time synchronization configuration file must have mode 0640 or less permissive.

Information

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. File permissions more permissive than 0640 for time synchronization configuration file may allow access and change the config file by system intruders or malicious users, could result in the failure of time synchronization.

Solution

Change the mode of the "ntp.conf" file to "0640" or less permissive:
# chmod 0640 /etc/ntp.conf
