STIGQter STIGQter: STIG Summary: VMware vRealize Automation 7.x SLES Security Technical Implementation Guide Version: 1 Release: 1 Benchmark Date: 28 Sep 2018:

The SLES for vRealize must, for networked systems, compare internal information system clocks at least every 24 hours with a server which is synchronized to one of the redundant United States Naval Observatory (USNO) time servers, or a time server designated for the appropriate DoD network (NIPRNet/SIPRNet), and/or the Global Positioning System (GPS).

Fix Recommendation

To specify a remote NTP server for time synchronization, edit the file "/etc/ntp.conf". Add or correct the following lines, substituting the IP or hostname of a remote NTP server for "ntpserver" by using the following command:

# echo "server [ntpserver]" >> /etc/ntp.conf

Replace [ntpserver] with one of the USNO time servers. This instructs the NTP software to contact that remote server to obtain time data.

Restart the service with:

# service ntp restart

Check Contents

A remote NTP server should be configured for time synchronization. To verify one is configured, open the following file:

# cat /etc/ntp.conf | grep server | grep -v '^#'
# cat /etc/ntp.conf | grep peer | grep -v '^#'
# cat /etc/ntp.conf | grep multicastclient | grep -v '^#'

Confirm the servers and peers or multicastclient (as applicable) are local or an authoritative U.S. DoD source.

If a non-local/non-authoritative time-server is used, this is a finding.
