Security assessment: Remove non-admin accounts with DCSync permissions

This article describes the Remove non-admin accounts with DCSync permissions security assessment, which identifies risky DCSync permission settings.

Why might the DCSync permission be a risk?

Accounts with the DCSync permission can initiate domain replication. Attackers can potentially exploit domain replication to gain unauthorized access, manipulate domain data, or compromise the integrity and availability of your Active Directory environment.

It's crucial to carefully manage and restrict the membership of this group to ensure the security and integrity of your domain replication process.

How do I use this security assessment to improve my organizational security posture?
