To meet these requirements at the VALIDATE, CONTEXT category auditing needs to be implemented at database level. 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, VALIDATESTATUS, ERRORTYPE AS ERRORTYPE FROM SYSCAT.AUDITPOLICIES WHERE AUDITPOLICYID = If the values for CONTEXTSTATUS and VALIDATESTATUS are not 'B' (Both) or ERRORTYPE is not 'A' (Audit), this is a finding. |

Run the following command to define an audit policy with the needed subset using the CREATE AUDIT POLICY SQL statement: DB2> CREATE AUDIT POLICY CATEGORIES VALIDATE STATUS BOTH, 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 |
