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 simply create a new account. Auditing of account creation is one method for mitigating this risk. A comprehensive account management process will ensure an audit trail documents the creation of user accounts and, as required, notifies administrators and/or managers. Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.
