Privileged Account and Session Management (PASM) refers to the policies and practices used to secure accounts with elevated permissions and the sessions in which those accounts are active. These privileged accounts often have access to critical systems and sensitive data, making them prime targets for cyberattacks.
Why Is Privileged Account and Session Management Critical?
Privileged accounts are the gateway to an organization’s most sensitive systems, data, and operations. These accounts have elevated permissions that enable administrative tasks such as managing configurations, accessing confidential files, or controlling critical infrastructure. While essential for day-to-day operations, their power also makes them prime targets for cyberattacks.
Key Risks of Poor Management
- Unauthorized Access: If a privileged account is compromised, attackers can exploit it to infiltrate systems, steal sensitive data, or disrupt operations.
- Insider Threats: Employees with excessive or unnecessary privileges can unintentionally or maliciously misuse their access, leading to data leaks or system failures.
- Regulatory Non-Compliance: Many regulations, such as GDPR, HIPAA, and PCI DSS, require stringent controls over privileged accounts. Failure to manage these accounts effectively can result in hefty fines and reputational damage.
- Audit and Accountability Challenges: Without proper session monitoring and management, it’s difficult to trace actions back to individual users, creating blind spots in investigations and audits.
The Importance of Effective PASM
- Minimizing Attack Surfaces: Limiting privileged access reduces the number of potential entry points for attackers, making systems harder to penetrate.
- Ensuring Accountability: Monitoring and recording sessions create an auditable trail of actions, enabling organizations to detect suspicious behavior and maintain transparency.
- Reducing Damage in Case of Breach: Strong controls, such as session monitoring and just-in-time access, help contain breaches by limiting how much damage a compromised account can cause.
- Supporting Operational Efficiency: Automated tools and clear policies streamline the management of privileged accounts, reducing administrative overhead and errors.
10 Best Practices for Privileged Account and Session Management
1. Conduct a Comprehensive Audit
Effective management starts with visibility. Conducting a detailed audit of all privileged accounts is essential for identifying risks and establishing control over these critical resources.
Why Auditing Matters
Privileged accounts often proliferate over time, especially in organizations with complex IT ecosystems. This sprawl can lead to orphaned accounts, untracked credentials, and permissions that far exceed necessity—all of which are significant security vulnerabilities.
Steps to Perform a Thorough Audit
- Inventory All Privileged Accounts: Include administrative, service, and third-party accounts. Pay special attention to accounts used for legacy systems, which are often overlooked.
- Evaluate Permissions: Review what each account can access and ensure permissions align with current roles and responsibilities.
- Eliminate Redundancies: Identify and disable orphaned or unnecessary accounts to reduce your attack surface.
- Utilize Audit Tools: Employ automated tools that can discover privileged accounts across networks and cloud environments, ensuring a comprehensive inventory.
A well-executed audit not only identifies vulnerabilities but also provides a roadmap for better governance.
2. Implement Strong Authentication Mechanisms
Once accounts are identified, securing access to them is the next priority. Strong authentication mechanisms, particularly multi-factor authentication (MFA), are critical to reducing unauthorized access.
Why Strong Authentication Is Essential
Passwords alone are insufficient to secure privileged accounts. Cybercriminals often exploit weak, reused, or stolen passwords to gain access. MFA mitigates this risk by requiring an additional verification step, making unauthorized access exponentially harder.
How to Strengthen Authentication
- Implement MFA Across All Privileged Accounts: Ensure privileged users verify their identity with a secondary factor, such as a biometric scan, hardware token, or mobile authenticator.
- Leverage Adaptive Authentication: Use risk-based approaches that factor in location, device, and user behavior to adjust security requirements dynamically.
- Regularly Update Authentication Methods: Periodically review and upgrade authentication mechanisms to incorporate new technologies, such as passwordless authentication.
By adding robust authentication layers, organizations can significantly improve the security posture of their privileged accounts.
3. Enforce the Principle of Least Privilege
The principle of least privilege (PoLP) ensures that users and systems have only the minimum access necessary to perform their tasks. This minimizes the damage that can result from an account being compromised.
Why PoLP Is Critical
Overly broad permissions increase the risk of insider threats and the potential damage from external breaches. By restricting privileges, organizations limit the scope of what an attacker can exploit.
Steps to Implement PoLP
- Role-Based Access Controls (RBAC): Assign permissions based on predefined roles rather than individuals to maintain consistency and streamline privilege management.
- Implement Just-In-Time Access: Provide temporary access to privileged accounts only when needed, automatically revoking it afterward.
- Conduct Regular Reviews: Periodically reassess permissions to ensure they remain aligned with current roles and responsibilities.
- Enforce Segmentation: Isolate sensitive systems and grant access to them only on a need-to-know basis.
Implementing PoLP reduces unnecessary exposure and strengthens the overall security framework of an organization.
4. Regularly Rotate Privileged Credentials
Static credentials are a major vulnerability. If privileged account credentials remain unchanged over long periods, they become easy targets for attackers. Regular rotation minimizes the risk of exploitation.
The Dangers of Static Credentials
- Extended Exposure: Stolen or compromised credentials can be used for months or years without detection.
- Credential Reuse: Passwords often get reused across accounts, increasing the risk of a broader breach.
Best Practices for Rotating Credentials
- Automate the Process: Use privileged access management (PAM) tools to enforce periodic credential changes without manual intervention.
- Set Clear Policies: Define rules for the frequency of password rotation and ensure they comply with industry standards.
- Encrypt and Vault Credentials: Store sensitive credentials in a secure vault to prevent unauthorized access.
Regular rotation reduces the utility of stolen credentials, protecting systems from prolonged compromise.
5. Monitor and Record Privileged Sessions
Monitoring privileged sessions provides visibility into how privileged accounts are used, allowing organizations to detect suspicious activity in real time and maintain a clear audit trail.
The Importance of Session Monitoring
Unmonitored sessions create blind spots, allowing malicious actors or negligent users to operate undetected. Detailed session logs not only enhance security but also support compliance with regulatory standards.
How to Monitor Effectively
- Deploy Session Recording Tools: Use PAM solutions to record privileged account activity, capturing commands executed and data accessed.
- Set Alerts for Anomalies: Define thresholds for unusual activity, such as logins from unexpected locations or at odd hours.
- Conduct Log Reviews: Regularly analyze session logs for patterns that might indicate a security issue.
- Enable Real-Time Monitoring: For high-risk systems, consider live session monitoring to allow for immediate intervention if needed.
Proactive monitoring not only helps identify threats early but also creates accountability for how privileged accounts are used.
6. Implement Just-In-Time (JIT) Privileged Access
JIT privileged access is a security approach that grants users elevated permissions only for the duration needed to complete specific tasks. Once the task is finished, access is automatically revoked.
Why JIT Access Is Important
Persistent access increases the risk of misuse and gives attackers a larger window of opportunity if an account is compromised. JIT access limits exposure, reducing the likelihood of unauthorized activities and the impact of potential breaches.
Benefits of JIT Access
- Minimized Attack Surface: Temporary access reduces the time accounts remain vulnerable.
- Enhanced Compliance: Many regulations, such as GDPR and HIPAA, encourage the use of least privilege and time-limited access for sensitive systems.
- Accountability: Granting access only for specific tasks creates a clear trail of who accessed what, when, and why.
How to Implement JIT Access
- Define Access Windows: Establish policies that specify how long privileges can be granted for various tasks.
- Leverage PAM Tools: Use tools with JIT capabilities to automate temporary privilege assignments and their expiration.
- Integrate Workflow Approvals: Require manager or administrator approval before granting JIT access.
JIT access balances operational flexibility with robust security, making it a critical component of modern privileged account management.
7. Use Privileged Access Management (PAM) Solutions
Privileged Access Management (PAM) solutions are purpose-built tools that centralize and automate the security of privileged accounts. These tools streamline the enforcement of best practices and provide advanced monitoring and control capabilities.
Why PAM Solutions Are Essential
Manually managing privileged accounts is inefficient and prone to human error. PAM solutions offer a unified platform to enforce policies, monitor usage, and respond to threats in real time.
Key Features of a PAM Solution

8. Conduct Regular Training and Awareness Programs
Even the most secure systems can be compromised if users are unaware of best practices and risks. Regular cyber security training ensures privileged users understand their responsibilities and how to use privileged accounts securely.
Why Training Matters
Privileged users often handle sensitive systems and data. A lack of awareness can lead to unintentional errors, such as sharing credentials or falling for phishing scams, which attackers frequently exploit.
Topics to Cover in Training
- Recognizing Social Engineering: Teach users how to identify and avoid phishing and other manipulation tactics.
- Password and Credential Security: Emphasize the importance of strong, unique passwords and the proper use of password vaults.
- Incident Reporting: Train users to recognize and report suspicious activities promptly.
Delivery Methods for Training
- Interactive Workshops: Engage users through real-world scenarios and role-playing exercises.
- Online Modules: Provide flexible, self-paced learning options for distributed teams.
- Regular Simulations: Conduct phishing or other attack simulations to test and reinforce learning.
Training empowers users to act as the first line of defense, reducing the risk of human error compromising privileged accounts.
9. Establish a Robust Incident Response Plan
No system is immune to breaches. A well-prepared incident response plan ensures that your organization can act quickly and effectively when privileged accounts are compromised.
Why an Incident Response Plan Is Crucial
A rapid response limits the damage caused by breaches, minimizes downtime, and demonstrates due diligence to stakeholders and regulators. Without a plan, organizations risk delayed reactions and poorly coordinated efforts.
Key Components of an Effective Plan
- Clear Roles and Responsibilities: Assign roles for identifying, containing, and remediating incidents.
- Detailed Playbooks: Provide step-by-step guidance for handling specific scenarios, such as credential theft or unauthorized access.
- Communication Protocols: Ensure timely and effective communication between internal teams and external stakeholders.
Steps to Take During a Breach
- Contain the Incident: Immediately disable compromised accounts and isolate affected systems.
- Analyze the Breach: Review logs and session recordings to determine the cause and scope of the attack.
- Remediate and Recover: Reset credentials, patch vulnerabilities, and restore systems to normal operations.
- Document Lessons Learned: Conduct a post-incident review to identify improvements for future resilience.
A robust response plan transforms incidents into manageable events, reducing their overall impact.
10. Regularly Review and Update Policies
Cybersecurity is a rapidly evolving field, and policies must adapt to keep pace with new threats, technologies, and regulatory requirements. Regular reviews ensure that your privileged account management strategy remains effective and compliant.
Why Policy Updates Are Important
Stale or outdated policies can create gaps in security or lead to non-compliance with regulations. Continuous refinement ensures your organization is prepared for emerging challenges.
How to Conduct a Policy Review
- Schedule Regular Reviews: Establish a routine for assessing policies, such as quarterly or annually.
- Involve Stakeholders: Gather input from IT, security, and compliance teams to ensure policies align with organizational goals.
- Test Policy Effectiveness: Simulate potential scenarios to determine if current policies adequately address risks.
Policies to Keep Updated
- Access Control Policies: Ensure they reflect current roles, responsibilities, and systems.
- Incident Response Protocols: Update procedures based on recent incidents and lessons learned.
- Compliance Requirements: Align with the latest regulations, such as GDPR, HIPAA, or ISO standards.
Privileged Account and Session Management is not a one-time effort but an ongoing commitment to securing critical systems and data. As a core aspect of any robust cyber security solution, implementing these ten best practices—from conducting audits and enforcing strong authentication to adopting PAM tools and maintaining up-to-date policies—helps organizations protect privileged accounts, reduce risks, and foster trust with stakeholders.
Effective PASM is about proactive, consistent action. With the right strategies and tools, your organization can stay one step ahead of threats while ensuring compliance and operational efficiency.
