DB2 must generate audit records when categorized information (e.g., classification levels/security levels) is deleted.
Changes in categorized information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected. For detailed information on categorizing information, refer t...Rule Medium Severity -

Group -
DB2 must generate audit records showing starting and ending time for user access to the database(s).
For completeness of forensic analysis, it is necessary to know how long a user's (or other principal's) connection to the DBMS lasts. This can be achieved by recording disconnections, in addition t...Rule Medium Severity -

Group -
DB2 must generate audit records when concurrent logons/connections by the same user from different workstations occur.
For completeness of forensic analysis, it is necessary to track who logs on to the DBMS. Concurrent connections by the same user from multiple workstations may be valid use of the system; or such ...Rule Medium Severity -

Group -
DB2 must off-load audit data to a separate log management facility; this must be continuous and in near real time for systems with a network connection to the storage facility and weekly or more often for stand-alone systems.
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. T...Rule Medium Severity -
