TL;DR: Active Directory remains a prime attack vector because attackers often rely on misconfigurations, over-privileged accounts, stale identities, weak service account hygiene, and legacy protocols rather than novel exploits, according to One Identity’s analysis. The governance lesson is clear: identity attack paths persist when lifecycle controls and least privilege are treated as optional.
Editorial analysis by NHI Mgmt Group, based on content published by One Identity: “Performing Maintenance”.
Key questions
Q: What breaks when Active Directory is left with too many privileged paths?
A: The directory stops behaving like a controlled identity system and starts behaving like a privilege graph.
Q: Why do stale privileged accounts increase breach impact?
A: They give an attacker more access than the person's current role would justify.
Q: What are the signs that service account management is failing?
A: Warning signs include aged accounts, passwords that never expire, shared privileged credentials, unknown owners, and service accounts that are not tied to a documented application or dependency.
Practitioner guidance
- Audit privileged group membership Review Domain Admins, Enterprise Admins and custom high-privilege groups for accounts that no longer need elevation.
- Move high-risk admin access to JIT Use just-in-time elevation for administrative tasks so privileged credentials are exposed for the shortest possible window.
- Inventory and harden service accounts Replace human-owned service accounts with group managed service accounts where possible, and enforce long passwords and tight permissions where migration is not yet possible.
Bottom line: Active Directory attacks often succeed through misconfiguration and privilege sprawl rather than advanced exploitation, which makes governance quality the decisive control variable.

Active Directory misconfiguration is an identity governance failure, not just an administration problem. The article shows that attackers often succeed through ordinary privilege sprawl, stale accounts and weak service account controls rather than advanced exploitation. That means the real issue is whether the directory is being governed as a living identity system or merely operated as infrastructure. Practitioners should treat AD misconfiguration as evidence that governance and operations have drifted apart.
A few things that frame the scale:
- 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface, according to the Ultimate Guide to NHIs.
- 49% of IT professionals would prioritise improving privileged access management if the decision were theirs alone, according to Netwrix's 2023 Hybrid Security Trends Report.
A question worth separating out:
Q: How should teams decide when to disable legacy authentication in Active Directory?
A: Teams should disable legacy authentication when the business no longer depends on it and a modern protocol can satisfy the same access need. The key decision is whether the compatibility benefit still outweighs the exposure from weaker encryption and replay-friendly authentication paths. In most hardened environments, continued tolerance is a governance debt, not a technical requirement.
