In the event of a logging failure, caused by loss of communications with the central logging server, the DBN-6300 must queue audit records locally until communication is restored or until the audit records are retrieved manually or using automated synchronization tools.

Description

<VulnDiscussion>It is critical that when the IDPS is at risk of failing to process audit logs as required, it take action to mitigate the failure. Audit processing failures include software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. Responses to audit failure depend upon the nature of the failure. The DBN-6300 performs a critical security function; therefore, its continued operation is imperative. Since availability of the DBN-6300 is an overriding concern, shutting down the system in the event of an audit failure should be avoided, except as a last resort. The SYSLOG protocol does not support automated synchronization; however, this functionality may be provided by Network Management Systems (NMSs), which are not within the scope of this STIG.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
