Privileged access management (PAM) has become a critical security priority as organizations face sophisticated cyber threats. Recent research from Microsoft shows that privileged credentials are involved in 80% of security breaches, making strong PAM best practices essential for every organization.
This guide outlines the five most effective privileged access management best practices security teams are implementing in 2025. Each practice is designed to address specific vulnerabilities while remaining straightforward to implement, giving you immediate steps to reduce your risk exposure.
Understanding Privileged Access Management
Privileged access management serves as the foundation of effective security architecture and provides your organization’s primary defense against credential-based attacks.
What Is Privileged Access Management?
Privileged access management encompasses the strategies, processes, and technologies used to secure, control, and monitor access to an organization’s critical systems and sensitive data. Unlike regular access management, PAM specifically focuses on securing accounts with elevated permissions that could cause significant damage if compromised.
While identity and access management (IAM) governs all user identities and their access rights, PAM specifically addresses high-power accounts with administrative capabilities. PAM provides more stringent controls, detailed monitoring, and safeguards against misuse of elevated permissions.
Why PAM Matters for Your Security Strategy
Privileged access management plays a critical role in your security approach. A single compromised admin account can provide enough access for malicious actors to steal data, deploy ransomware, or create persistent backdoors.
Effective PAM implementations reduce your attack surface, limit lateral movement opportunities for intruders, and provide crucial audit trails for compliance and forensic analysis. PAM becomes even more critical for organizations with hybrid environments spanning on-premises and cloud resources as administrative boundaries blur across platforms.
Common Types of Privileged Accounts
Understanding the various privileged accounts in your environment is the first step toward protecting them. Each type presents unique security challenges:
- Domain administrator accounts represent the highest level of privilege in your environment, with near-unlimited control over your Active Directory infrastructure. These “keys to the kingdom” require exceptional protection measures, including just-in-time access and comprehensive activity monitoring.
- Local administrator accounts exist on individual endpoints but can still provide attackers with valuable footholds.
- Service accounts, often overlooked in PAM strategies, run critical background processes with persistent, elevated privileges, making them attractive persistence targets for attackers when credentials are hardcoded or rarely rotated.

Top 5 Privileged Access Management Best Practices
These five privileged access management best practices represent the foundation of any effective PAM strategy, balancing security requirements with operational efficiency to protect your most sensitive systems.
1. Implement the Principle of Least Privilege
The principle of least privilege (PoLP) ensures that users receive only the minimum permissions necessary to perform their job functions and nothing more.
Implementing PoLP involves four steps:
- Inventory Privileged Accounts: Document all accounts with elevated permissions across your environment.
- Assess Necessity: Evaluate each privilege against actual job requirements.
- Rightsize Permissions: Remove unnecessary rights and create role-based access profiles.
- Verify and Test: Check that the reduced permissions still allow legitimate work functions.
Be sure to create standardized role profiles that match specific job functions, then migrate users to these roles. Also, maintain a regular review cycle to prevent privilege creep: the gradual accumulation of unnecessary permissions that occurs naturally over time without proper oversight.
2. Establish Just-in-Time Access Protocols
Just-in-time (JIT) access represents a significant advancement in privileged access management best practices. This approach replaces permanent privileged access with temporary, time-limited permissions that automatically expire after use.
When administrators only have elevated privileges for the minimum time necessary to complete a task, the window of opportunity for attackers dramatically shrinks even if credentials are compromised.
JIT access implementation requires a request-and-approval workflow where administrators request elevated access for specific tasks. These requests should specify the systems affected, actions to be performed, and necessary duration. Approvals can be automated for routine tasks or require management authorization for sensitive systems. The key benefit is that privileged access exists only when actively needed, reducing the opportunity for lateral movement by attackers.
3. Deploy Multi-Factor Authentication for All Privileged Access
Multi-factor authentication (MFA) provides critical protection against credential theft and reuse. For privileged accounts, MFA should be non-negotiable, as these credentials represent high-value targets for attackers. Recent research from Microsoft Security shows that MFA blocks 99.9% of automated account compromise attempts.
When implementing MFA for privileged accounts, prioritize hardware security keys or authenticator apps over SMS-based verification, which remains vulnerable to SIM-swapping attacks. For the highest security environments, consider adaptive authentication that examines contextual factors like location, device, and behavioral patterns before granting access.
4. Automate Password Management and Rotation
Manual password management for privileged accounts introduces significant risk through predictable patterns, shared credentials, and infrequent rotation. Automated password management addresses these issues by enforcing complexity requirements and regular rotation schedules without human intervention.
Effective password automation for privileged accounts includes random generation of complex credentials, secure storage in encrypted vaults, and automated rotation after use or at regular intervals. Special attention should be paid to service accounts, which often maintain the same credentials for extended periods due to application dependencies. Implementing automated discovery tools helps identify forgotten privileged accounts that might otherwise escape your rotation policy.
Password Management Approach | Security Level | Operational Impact | Best For |
Manual rotation (quarterly) | Low | High disruption risk | Small environments only |
Scheduled automation (monthly) | Medium | Moderate management | Mid-sized organizations |
Check-out/check-in with rotation | High | Low (after setup) | Sensitive systems |
One-time use passwords | Very high | Requires PAM solution | Critical infrastructure |
5. Monitor and Audit Privileged Sessions
Session monitoring creates accountability by recording privileged actions while providing valuable forensic evidence if incidents occur.
Implement session monitoring tools that capture command-line activities, configuration changes, and accessed resources. For the highest-risk systems, consider solutions that record full video sessions for later review. Establish baseline patterns of normal administrative behavior through analytics to help identify unusual activities that may indicate compromise.
A risk-based approach to monitoring depth-critical infrastructure warrants greater scrutiny than standard systems. Integrate privileged session monitoring with your security information and event management (SIEM) platform to correlate administrative actions with other security events, creating a more complete security picture.

Measuring PAM Effectiveness
Once you’ve implemented privileged access management best practices, measuring their effectiveness becomes crucial for continuous improvement. The right metrics and evaluation methods help you identify gaps in your security posture and demonstrate the value of your PAM program to stakeholders.
Key Metrics for Evaluating Your PAM Program
Tracking specific measurements provides concrete evidence of your PAM program’s success or areas needing improvement. These metrics help security teams quantify risk reduction and program effectiveness.
Focus on both security outcomes (incidents prevented, attack surface reduction) and operational metrics (time-to-access, approval speeds) to get a complete picture of your program’s performance.
The most valuable PAM metrics include dormant privilege identification rate, average time to access for legitimate requests, privilege escalation approval rates, and failed authentication attempts.
Common Implementation Challenges and Solutions
Even with careful planning, PAM implementations face obstacles that can hinder their effectiveness. Understanding these challenges helps teams prepare appropriate solutions in advance.
The most common hurdles include resistance from IT teams used to unrestricted access, identifying all privileged accounts (especially service accounts), and managing emergency access procedures. Technical debt and legacy systems often complicate PAM implementation, requiring customized approaches for older applications with hardcoded credentials.
To address these challenges effectively, organizations should consider the following best practices:
- Gain stakeholder buy-in by demonstrating how PAM enhances rather than hinders productivity.
- Start with discovery tools to identify all privileged accounts before attempting to control them.
- Implement in phases rather than attempting to secure all systems simultaneously.
- Create clear exception processes for emergency access scenarios.

The most critical privileged access management best practices for hybrid environments include implementing least privilege, using just-in-time access, enforcing multi-factor authentication, automating password management, and conducting comprehensive session monitoring. Organizations should prioritize solutions that provide unified visibility and control across both on-premises and cloud infrastructure to maintain consistent security policies.
Organizations should review their privileged access management best practices at least quarterly, with thorough assessments conducted annually to identify new risks, privilege creep, and dormant accounts. Additional reviews become necessary following major infrastructure changes, mergers/acquisitions, or in response to industry-specific compliance requirements or security incidents.
Good metrics include reduction in privileged account scope, average time-to-access for legitimate requests, failed authentication attempts, number of dormant privileged accounts discovered, and time to detect unauthorized privilege escalation. Organizations should also track operational metrics like admin productivity and system availability to ensure that security controls aren’t impeding business functions.
While the core privileged access management best practices remain consistent regardless of organization size, enterprises typically need more sophisticated automation, integration capabilities, and delegation controls to manage their complex environments. Small businesses can often begin with basic controls like least privilege and MFA, gradually adding more advanced practices such as session monitoring and just-in-time access as they expand and their security maturity increases.
Privileged access management best practices form a critical foundation for zero-trust architecture by ensuring that even high-power administrative accounts must continuously verify their identity and authorization before accessing sensitive resources. The principles of least privilege, just-in-time access, and comprehensive monitoring align perfectly with zero-trust’s “never trust, always verify” philosophy.
