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 ISSO. 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. This control applies to locally defined accounts, including the root account and the account of last resort.

Check Text ( C-55807r2_chk )
Determine if the network device generates alerts that can be forwarded to the administrators and ISSO when accounts are modified. This requirement may be verified by demonstration or configuration review. If alerts are not generated when accounts are modified and forwarded to the administrators and ISSO, this is a finding.

Fix Text (F-60051r2_fix)
Configure the network device to send a notification message to the administrators and ISSO when accounts are modified.
