Background for this topic.
Active Directory is a centralized system that manages user accounts, devices, and permissions within a network domain. It organizes resources hierarchically, enabling authentication and access control across an organization’s IT environment. This structure allows administrators to enforce policies and manage identities consistently.
From a security standpoint, Active Directory is a critical asset because attackers who gain control over it can access or manipulate many network resources. Key risks include credential theft through techniques like Kerberos ticket attacks, privilege escalation by exploiting misconfigured permissions, and persistence via compromised service accounts. Effective defense involves strict access controls, continuous monitoring for unusual account behavior, and regular audits of group memberships and delegated rights to limit exposure.
