Key Point: Active Directory as the foundation of enterprise security requires specialized recovery procedures, since outages or compromises endanger access to critical systems.
Active Directory has been the central authentication system in enterprise networks for about 25 years, but is increasingly becoming a target of ransomware and sabotage attacks. A secure recovery strategy for AD forests is therefore necessary for business continuity.
Active Directory (AD) has managed authentication and authorization in enterprise networks for around 25 years and is thus critical infrastructure for the operation of business-critical applications. The directory service controls user rights, device access, and trust relationships between systems.
This very central role, however, makes AD an attractive target for attackers. Ransomware campaigns and targeted IT sabotage regularly target AD forests to gain network control, escalate access, or block recovery attempts. A compromise of the directory service thus endangers the availability and integrity of the entire network.
For CISOs, this results in increased effort in preventing AD attacks as well as in planning emergency measures. A documented recovery strategy for AD forests — including separate backups, snapshots, and isolation procedures — is therefore essential to return to a secure operating state in reasonable time after compromise or total failure.
