As traditional perimeters fade, identity now defines the frontline of security – and it’s where many breaches begin. Misconfigurations in Identity and Access Management (IAM) remain one of the most common and costly vulnerabilities organizations face today. They’re not just technical oversights – they are open doors waiting to be exploited.
Here are five IAM misconfigurations we frequently encounter, why they’re dangerous, and how to proactively fix them before they lead to breaches, fines, or worse.
1. Orphaned Accounts
The problem: Users leave the organization, but their accounts — and access — remain active. These forgotten identities can easily be hijacked by attackers, especially if they belong to former employees with elevated privileges.
The fix:
- Integrate IAM systems with HR workflows to automate deprovisioning.
- Run regular account audits to identify inactive users.
- Enforce a „no orphan account“ policy as part of your governance.
2. Excessive Privileges
The problem: Employees accumulate access over time — often due to role changes or temporary projects — but rarely lose it. Over time, this results in users having far more access than they need.
The fix:
- Implement Role-Based Access Control (RBAC) to assign permissions based on job function
- Enforce the principle of least privilege and conduct quarterly access reviews.
- Use automation to remove unnecessary permissions after a defined period.
3. Overuse of Admin Rights
The problem: When everyone is an admin, no one is secure. Overprivileged accounts increase your attack surface and the potential damage from account compromise.
The fix:
- Deploy a Privileged Access Management (PAM) solution to control and monitor admin access.
- Require just-in-time (JIT) access elevation — only when needed, for a limited time.
- Implement multi-person approval for high-risk actions.
4. No MFA on Critical Systems
The problem: Despite being one of the simplest security measures, Multi-Factor Authentication (MFA) is still not consistently enforced across sensitive systems. This leaves critical access points — like VPNs or cloud admin consoles — vulnerable to credential theft.
The fix:
- Make MFA mandatory across all high-risk access points: remote access, cloud platforms, admin portals, and email.
- Consider adaptive MFA based on user risk, location, or behavior.
- Educate users on phishing-resistant options like FIDO2 or hardware tokens.
5. Lack of Visibility and Logging
The problem: If you don’t know who accessed what, when, or why — you can’t detect breaches, investigate incidents, or prove compliance. Flying blind is not a strategy.
The fix:
- Enable comprehensive logging of access activity across all systems.
- Integrate logs with a SIEM to enable real-time monitoring and anomaly detection.
- Review access logs routinely, not just during audits or after incidents.
IAM isn’t just an IT concern – it’s a core pillar of enterprise security. These five misconfigurations are not theoretical risks – they’re real, recurring gaps that attackers are actively exploiting. Fortunately, they’re also preventable. By proactively addressing these weak points, you not only reduce your risk exposure but also strengthen your organization’s security posture, resilience, and trustworthiness.
