Description
Auditing of account creation is a method and best practice for mitigating the risk of an attacker creating a persistent method of reestablishing access. A comprehensive account management process will ensure an audit trail which documents the creation of accounts and if required notifies administrators. Such a process greatly reduces the risk of accounts being created outside the normal approval process and provides logging that can be used for forensic purposes. Additionally, the audit records of account creation can be compared to the known approved account creation list.
