Privileged Access Management: Securing Admin Accounts

Privileged accounts are the keys to the kingdom—they provide elevated access to critical systems and data. According to the Verizon Data Breach Investigations Report, 80% of breaches involve compromised credentials, and privileged accounts are prime targets. The SANS Institute reports that organizations with effective privileged access management (PAM) reduce security incidents by an average of 50%. The NIST SP 800-53 emphasizes PAM as a critical security control. This guide covers best practices for securing privileged accounts and implementing effective PAM.

Understanding Privileged Accounts

Privileged accounts include:

Why Privileged Accounts Are Targeted

Privileged accounts are high-value targets because they provide:

• Access to sensitive data and systems
• Ability to modify security configurations
• Capability to create new accounts and grant permissions
• Access to multiple systems through lateral movement
• Ability to cover tracks and evade detection

PAM Best Practices

1. Inventory Privileged Accounts

Start by identifying all privileged accounts in your environment. CyberXprt Access Control provides automated privileged account discovery.

2. Implement Least Privilege

Grant only the minimum privileges necessary for each role or task. Avoid using highly privileged accounts for routine operations.

3. Use Privileged Access Workstations

Use dedicated, hardened workstations for privileged access to reduce attack surface.

4. Implement Just-In-Time Access

Grant privileged access only when needed and for limited duration, rather than permanent access.

5. Enforce Strong Authentication

Require multi-factor authentication (MFA) for all privileged access:

6. Implement Session Management

Monitor and control privileged sessions:

• Session recording and monitoring
• Session time limits
• Session termination capabilities
• Real-time session alerts

7. Rotate Credentials Regularly

Regularly rotate privileged account credentials, especially for service accounts and shared accounts.

8. Monitor and Audit

Monitor all privileged access and maintain comprehensive audit logs:

• All privileged access attempts
• Successful and failed authentications
• Privileged actions and commands
• Session activities

PAM Implementation Steps

Step 1: Discovery

Discover all privileged accounts across your environment, including local, domain, cloud, and service accounts.

Step 2: Classification

Classify privileged accounts by type, criticality, and access level.

Step 3: Centralization

Centralize privileged account management in a PAM solution or vault.

Step 4: Automation

Automate credential rotation, access provisioning, and compliance checking.

Step 5: Integration

Integrate PAM with identity management, SIEM, and other security tools.

Common PAM Challenges

Challenge 1: Shared Accounts

Shared privileged accounts make accountability difficult. Solution: Eliminate shared accounts or use PAM solutions that provide individual accountability for shared account access.

Challenge 2: Service Accounts

Service accounts often have excessive privileges and rarely rotated credentials. Solution: Implement automated credential rotation and least privilege for service accounts.

Challenge 3: Legacy Systems

Legacy systems may not support modern PAM solutions. Solution: Use PAM solutions that support legacy systems or implement workarounds.

Conclusion

Privileged access management is essential for securing admin accounts and protecting critical systems. By implementing comprehensive PAM practices, organizations can significantly reduce the risk of privileged account compromise and limit the impact of security incidents.

To implement effective PAM, consider CyberXprt Access Control, which provides privileged account management, credential rotation, session management, and access monitoring.
