PostgreSQL must by default shut down upon audit failure, to include the unavailability of space for more audit log records; or must be configurable to shut down upon audit failure.
An XCCDF Rule
Description
<VulnDiscussion>It is critical that when PostgreSQL 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 mode. When the need for system availability does not outweigh the need for a complete audit trail, PostgreSQL should shut down immediately, rolling back all in-flight transactions. Systems where audit trail completeness is paramount will most likely be at a lower MAC level than MAC I; the final determination being the prerogative of the application owner, subject to Authorizing Official concurrence. Sufficient auditing resources must be allocated to avoid a shutdown in all but the most extreme situations.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
