The DBMS must support the requirement to automatically audit account creation.

Once an attacker establishes initial access to a system, they often attempt 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 and best practice for mitigating this risk. A comprehensive account management process will ensure an audit trail documents the creation of application user accounts and, as required, notifies administrators and/or application owners that they exist. Such a process greatly reduces the risk that accounts will be surreptitiously created and provides logging that can be used for forensic purposes.

Note that user authentication and account management should be done via an enterprise-wide mechanism whenever possible. Examples of enterprise-level authentication/access mechanisms include, but are not limited to, Active Directory and LDAP.

However, notwithstanding how accounts are managed, Oracle auditing must always be configured to capture account creation.
