GEN000241 - The system clock must be synchronized continuously.

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. Internal system clocks tend to drift and require periodic resynchronization to ensure their accuracy. Software, such as NTPD, can be used to continuously synchronize the system clock with authoritative sources. Alternatively, the system may be synchronized periodically, with a maximum of one day between synchronizations.

If the system is completely isolated (no connections to networks or other systems), time synchronization is not required as no correlation of events or operation of time-dependent protocols between systems will be necessary. If the system is completely isolated, this requirement is not applicable.

Solution

Determine the type of zone currently being secured.

# zonename

If the command output is not 'global', then NTP and NTP4 must be disabled.

# svcadm disable ntp
# svcadm disable ntp4

If the output from 'zonename' is 'global', then NTP or NTP4 must be enabled.

# svcadm enable ntp
or
# svcadm enable ntp4
