For the host and devices within its scope of coverage, the Central Log Server must be configured to send a real-time alert to the System Administrator (SA) and Information System Security Officer (ISSO) (at a minimum) of all audit failure events, such as loss of communications with hosts and devices, or if log records are no longer being received.

Description

<VulnDiscussion>It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit function and application operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less). User-configurable controls on the Central Log Server help avoid generating excessive numbers of alert messages. Define realistic alerting limits and thresholds to avoid creating excessive numbers of alerts for noncritical events. This requirement must be mapped to the severity levels used by the system to denote a failure, active attack, attack involving multiple systems, and other critical notifications, at a minimum. However, note that the IDS/IDPS and other monitoring systems may already be configured for direct notification of many types of critical security alerts.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
