| Account management and distribution is vital to the security of any DNS implementation. Once an attacker establishes initial access to a system, they often attempt to create a persistent method of re-establishing access. One way to accomplish this is for the attacker to simply create a new account. Notification of account creation is one method and best practice for mitigating this risk. Account management, as a whole, ensures access to DNS elements is being controlled in a secured manner by granting access to only authorized personnel with the appropriate and necessary privileges. Without a formal approval process for the deployment and modification of accounts, personnel without the proper need to know validation, may gain access to critical systems. It is imperative that all personnel who are granted accounts have completed and submitted the proper request forms and have been approved by the designated authority. Auditing account modification along with an automatic notification to appropriate individuals will provide the necessary reconciliation that account management procedures are being followed. |
