Description
Determining the correct time a particular application event occurred on a system is critical when conducting forensic analysis and investigating system events. Periodically synchronizing internal clocks with an authoritative time source is necessary to correctly correlate the timing of events that occur across the enterprise. The three authoritative time sources for Samsung Android are an authoritative time server that is synchronized with redundant United States Naval Observatory (USNO) time servers as designated for the appropriate DOD network (NIPRNet or SIPRNet), the Global Positioning System (GPS), or the wireless carrier. Time stamps generated by the audit system in Samsung Android must include both date and time. The time may be expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local time with an offset from UTC. SFRID: FMT_MOF_EXT.1.2 #47

ℹ️ Check
Review the configuration to determine if the Samsung Android devices are disallowing the users from changing the date and time. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device restrictions, verify "Configure Date/Time" is set to "Disallow". On the Samsung Android device: 1. Open Settings >> General management >> Date and time. 2. Verify "Automatic date and time" is on and the user cannot disable it. If on the management tool "Configure Date/Time" is not set to "Disallow", or on the Samsung Android device "Automatic date and time" is not set or the user can disable it, this is a finding.
