\n\t\t\t\t\t\t\t\t\t\tStep 2: Restore AD Database
Use authoritative or non-authoritative restore based on the incident scope: Authoritative restore: Ensures certain objects are treated as the \u201csource of truth,\u201d overwriting replication. Non-authoritative restore: Restores the domain controller to the state of the backup, then allows replication to update changes. <\/span><\/p>\n

Frequently Ask Questions<\/h2>\n<\/div>\n<\/div>\n
\n
\n
\n
\n
\n

What is an Active Directory compromise?<\/h3>\n<\/div>\n
\n

An Active Directory compromise occurs when attackers exploit weaknesses to gain unauthorized access. Common attacks include Pass-the-Hash, Kerberos ticket forgery, DCShadow, and privilege escalation. Early detection limits damage.<\/p>\n<\/div><\/div>\n

\n
\n

What are the first steps after detecting an AD compromise?<\/h3>\n<\/div>\n
\n

Immediate steps include isolating affected systems and accounts, stopping AD replication to limit spread, and alerting security teams. EDR and SIEM tools help automate containment and alerts.<\/p>\n<\/div><\/div>\n

\n
\n

How do you recover compromised credentials in AD?<\/h3>\n<\/div>\n
\n

Reset affected passwords, rotate the krbtgt account twice, remove unauthorized accounts, and enforce MFA. Automation reduces errors and speeds recovery.<\/p>\n<\/div><\/div>\n

\n
\n

What is the best approach to restore an AD database safely?<\/h3>\n<\/div>\n
\n

Confirm backups are clean, select the appropriate restore method, isolate domain controllers, restore AD, and validate replication and services. Regular testing ensures readiness.<\/p>\n<\/div><\/div>\n

\n
\n

How can organizations prevent future AD compromises?<\/h3>\n<\/div>\n
\n

Use layered AD security with MFA, JIT\/JEA, GPO enforcement, continuous monitoring, and automated response. Regular drills and updated playbooks improve resilience.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
