Monitoring event ID 4726.

  • Accounts that have Target Account/Security ID corresponding to high-value accounts, including administrators, built-in local administrators, domain administrators, and service accounts.
  • Accounts that have to be monitored for every change. This list can vary between enterprises and industries.
  • Local accounts, because these accounts are often not deleted, and this could serve as an indicator of malicious activity.
  • Accounts that should never be deleted (for example, service accounts).

The need for an auditing solution.

Auditing solutions like ADAudit Plus offer real-time monitoring, user and entity behavior analytics, and reports; together these features help secure your AD environment.

Around the clock, real-time monitoring.

Although you can attach a task to the security log and ask Windows to send you an email, you're limited to simply getting an email whenever event 4726 is generated. Windows also lacks the ability to apply more granular filters that are required to meet security recommendations.

For example, Windows can send you an email every time event 4726 is generated, but it can't tell the difference between regular and high-value accounts. Recieving alerts specifically for high-value accounts reduces the chance of missing out on critical notifications hidden among the heap of false-positive alerts.

With a tool like ADAudit Plus, not only can you apply granular filters to focus on real threats, you can receive real-time notifications via SMS, too.
