Title

The application must generate audit records when successful/unsuccessful attempts to access security levels occur. (Cat II impact)

Discussion

A security level denotes a permissions or authorization capability within the application. This is most often associated with a user role. Attempts to access a security level can occur when a user attempts an action such as escalating their privilege from within the application itself. Attempts to access a security level can be construed as an attempt to change your user role from within the application. Without generating audit records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter).

Check Content

Review the application documentation and interview the application administrator. Identify where the application logs are stored. Identify application functionality that provides privilege escalation or access to additional security levels within the application. This can be performing a function that escalates the privileges of the user, or accessing a protected area of the application that requires additional authentication in order to access. Authenticate to the application as a regular user. Using application functionality, attempt to access a different security level or domain within the application. Perform two attempts, one successfully and one unsuccessfully. Review the log data and ensure both the successful and unsuccessful access attempts are logged. If the application does not generate an audit record when successful and unsuccessful attempts to access security levels occur, this is a finding.

Fix Text

Configure the application to create an audit record for both successful and unsuccessful attempts to access security levels.
