Hardening Active Directory Configurations: Key Exposures

Directory environments act as the foundation of B2B corporate access. However, legacy configurations and lack of access auditing often leave them vulnerable to privilege escalation attacks.

One of the most common vulnerabilities is the existence of inactive administrator accounts. Attacks often target these dormant accounts to gain persistent access. KOOLIXA recommends enforcing an automated de-provisioning policy that flags and disables accounts inactive for more than 30 days.

Additionally, service accounts are frequently configured with excessive privileges. If an attacker compromises a web server running a privileged service account, they gain control of the domain controller. We implement Least Privilege Administration (PoLP) rules, locking down service accounts to their minimum required scopes.

Finally, enforce multi-factor authentication (MFA) on all access channels, including internal administration. KOOLIXA co-managed security desks monitor access logs in real-time, blocking anomalous logins immediately.
