Fix Recommendation

Run the following command to define an audit policy with the needed subset using the CREATE AUDIT POLICY SQL statement:
DB2> CREATE AUDIT POLICY <DB audit policy name>
CATEGORIES CONTEXT STATUS BOTH
ERROR TYPE AUDIT

To modify an existing audit policy, replace "CREATE" with "ALTER" in the preceding statement. Only the categories explicitly named in the statement will be affected. In this case, the changes take effect immediately.

If CREATE was used above, run the following command to apply the policy created above to the database:
DB2> AUDIT DATABASE USING POLICY <DB audit policy name>

Check Contents

Run the following SQL statement to ensure that an audit policy is defined upon the database:
DB2> SELECT AUDITPOLICYNAME, AUDITPOLICYID
FROM SYSCAT.AUDITUSE
WHERE OBJECTTYPE IN (' ')

If no rows are returned, this is a finding.

Using the AUDITPOLICYID from above query find the details of audit policy.
DB2> SELECT AUDITPOLICYNAME, CONTEXTSTATUS, ERRORTYPE AS ERRORTYPE
FROM SYSCAT.AUDITPOLICIES
WHERE AUDITPOLICYID = <audit policy ID>

If the value for CONTEXTSTATUS is not 'B' (Both) or ERRORTYPE is not 'A' (Audit), this is a finding.
