SV-89251r1_rule DB2 must generate audit records for all direct access to the database(s).

Vulnerability discussion

In this context, direct access is any query, command, or call to the DBMS that comes from any source other than the application(s) that it supports. Examples would be the command line or a database management utility program. The intent is to capture all activity from administrative and non-standard sources.

Check content

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.

Fix text

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

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
