Vulnerability Discussion

When application accounts are disabled, user accessibility is affected. Accounts are utilized for identifying individual users or for identifying the application processes themselves. Sending notification of account disabling events to the system administrator (SA) and information system security officer (ISSO) is one method for mitigating this risk. Such a capability greatly reduces the risk that application accessibility will be negatively affected for extended periods of time and also provides logging that can be used for forensic purposes.

To address access requirements, many operating systems can be integrated with enterprise-level authentication/access/auditing mechanisms that meet or exceed access control policy requirements.

Fix
