The Palo Alto Networks security platform must compare internal information system clocks at least every 24 hours with an authoritative time server.
Low Severity
<VulnDiscussion>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. Synchronizing internal information system clocks provides uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. Network Time Protocol (NTP) is used to synchronize the system clock of a computer to reference time source. The Palo Alto Networks security platform can be configured to use specified Network Time Protocol (NTP) servers. For synchronization with the NTP server(s), NTP uses a minimum polling value of 64 seconds and a maximum polling value of 1024 seconds. These minimum and maximum polling values are not configurable on the firewall.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
