Description
Once an attacker establishes initial 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 simply modify an existing account. Notification of account modification is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail which documents the modification of device administrator accounts and notifies administrators and Information Assurance Officers (IAO). Such a process greatly reduces the risk that accounts will be surreptitiously modified and provides logging that can be used for forensic purposes. The network device must generate the alert. Notification may be done by a management server.

Check Text ( C-55807r1_chk )
Determine if the network device generates alerts that can be forwarded to the administrators and IAO when accounts are modified. This requirement may be verified by demonstration or configuration review. If the network device is configured to use an authentication server which would perform this function, this is not a finding. If alerts are not generated when accounts are modified and forwarded to the administrators and IAO, this is a finding.
