Discussion

Use of categorized information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones. For detailed information on categorizing information, refer to FIPS Publication 199, Standards for Security Categorization of Federal Information and Information Systems, and FIPS Publication 200, Minimum Security Requirements for Federal Information and Information Systems.

Review the system documentation to determine whether it is required to track categories of information, such as classification or sensitivity level. If it is not, this is not applicable (NA).

To verify the database generates audit records when categorized information (e.g., classification levels/security levels) is unsuccessfully accessed the SECMAINT, CONTEXT category auditing must be implemented at the 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. 

Run the following SQL statement using the AUDITPOLICYID returned from query above to find the details of the audit policy: 
DB2> SELECT AUDITPOLICYNAME, CONTEXTSTATUS, SECMAINTSTATUS, ERRORTYPE AS ERRORTYPE 
           FROM SYSCAT.AUDITPOLICIES 
           WHERE AUDITPOLICYID = <audit policy ID>

If the values is not 'B' (Both) CONTEXTSTATUS, SECMAINTSTATUS, columns and the value in ERRORTYPE column set to 'A' (AUDIT) , this is a finding.
