DB2X-00-007700 - DB2 must provide an immediate real-time alert to appropriate support staff of all audit failure events requiring real-time alerts.

Information

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 capability, and system operation may be adversely affected.

The appropriate support staff include, at a minimum, the ISSO and the DBA/SA.

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).

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Run the following command to alter the audit policies and to set the ERRORTYPE to audit:
DB2>ALTER AUDIT POLICY <DB audit policy name> CATEGORIES AUDIT STATUS BOTH ERROR TYPE AUDIT

Monitor the diagnostic log file for audit failure error using the following command:

$db2diag -g msg:='Write to audit log failed'
