| Description | ||||
| Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Sources outside the configured acceptable allowance (drift) may be inaccurate. Synchronizing internal information system clocks provides uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. Organizations should consider endpoints that may not have regular access to the authoritative time server (e.g., mobile, teleworking, and tactical endpoints). | ||||

Check Text (C-261311r1038944_chk)
Verify that SLEM 5 clock must be configured to synchronize to an authoritative DOD time source when the time difference is greater than one second with the following command:
> sudo grep maxpoll /etc/chrony.conf
server 0.us.pool.ntp.mil maxpoll 16
If the "server" parameter is not set to an authoritative DOD time source, "maxpoll" is greater than "16", the line is commented out, or the line is missing, this is a finding.
Fix Text (F-64948r996403_fix)
SLEM 5 clock must be configured to synchronize to an authoritative DOD time source when the time difference is greater than one second.
To configure the system clock to synchronize to an authoritative DOD time source at least every 24 hours, edit the file "/etc/chrony.conf". Add or correct the following lines by replacing "<time_source>" with an authoritative DOD time source:
server <time_source> maxpoll 16
