GEN000244 - The system must use time sources local to the enclave.


A synchronized system clock is critical for the enforcement of time-based policies and the correlation of logs and audit records with other systems. The network architecture should provide multiple time servers within an enclave providing local service to the enclave and synchronize with time sources outside of the enclave. If this server is an enclave time server, this requirement is not applicable. 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.
NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.


If using ntpdate, remove NTP servers external to the enclave from the cron job running ntpdate.
If using the NTP daemon, remove the server line from ntp.conf for each NTP server external to the enclave.
