IBM z/OS system administrator must develop a procedure to notify system administrators (SAs) and information system security officers (ISSOs) of account enabling actions.

| Description | ||||
| Once an attacker establishes access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to enable an existing disabled account. Sending notification of account enabling actions to the SA and ISSO is one method for mitigating this risk. Such a capability greatly reduces the risk that operating system accessibility will be negatively affected for extended periods of time and also provides logging that can be used for forensic purposes. | ||||
