2. Strengthen authentication: Favor long passphrases and MFA. Avoid forced periodic resets unless there’s evidence of compromise. Screen against known-breached passwords.

3. Tighten Group Policy: Consolidate GPOs, document scope and precedence, and test changes in a staging OU before production.

4. Audit and monitor: Track privilege changes, logon failures, and lateral movement signals. Alert on anomalies.

5. Backup and recovery: Schedule system state and AD-aware backups. Practice forest and domain recovery procedures.

6. Least privilege: Use role-based groups, remove stale admin rights, and separate admin workstations.

7. User education: Coach users on phishing awareness and secure password habits to reduce account compromise.
