High-Intensity Cybersecurity & Offensive Depths
Active Directory and Entra ID Defense
Active Directory and Entra ID are the keys to most enterprises, and a single misconfiguration can let an attacker move from one compromised user to domain control. Defense means mapping attack paths, hardening privileged accounts, and monitoring for the techniques attackers actually use, such as Kerberoasting, DCSync, and token theft. Cloud identity adds its own risks around app registrations, consent grants, and legacy authentication protocols.
Главное
- Run BloodHound or PingCastle regularly to find and fix shortest paths to domain admin.
- Protect tier-zero assets with dedicated admin workstations and separate credentials per tier.
- Disable legacy authentication protocols and require phishing-resistant MFA for privileged roles.
- Monitor for DCSync, Kerberoasting, AS-REP roasting, and unusual replication activity.
- Review Entra ID app registrations, consent grants, and service principals for excessive permissions.
- Rotate krbtgt twice on a schedule and after any suspected compromise.
- Apply LAPS or equivalent to remove shared local admin passwords across endpoints.
- Alert on new domain admins, GPO changes, and trust modifications in real time.
Частые вопросы
Is Entra ID safer than on-prem AD?
It shifts the risk to cloud configuration and identity, which is safer only if configured with least privilege and MFA.
What is the most common AD attack path?
A phished user with excessive group membership or a service account with a weak or reused password.
How often should we audit AD?
Continuously for changes, with a full attack-path review at least quarterly.
Can we eliminate domain admin entirely?
Not fully, but tiering and just-in-time access can make standing domain admin rare and heavily monitored.
