Privileged Access Management (PAM) is a crucial security practice that focuses on managing and controlling access to privileged accounts within an organization. Privileged accounts are powerful user accounts with elevated permissions that grant access to critical systems, sensitive data, and administrative functions. As these accounts can potentially cause significant damage if misused or compromised, implementing a robust PAM solution is essential to enhance security, minimize the risk of insider threats, and protect against external cyberattacks. 

what is privileged access management

Types of Privileged Accounts

  • Local administrative accounts: Non-personal accounts with administrative access limited to the local host or instance.
  • Domain administrative accounts: Privileged accounts with administrative access across all workstations and servers within the domain.
  • Break glass (emergency/firecall) accounts: Unprivileged users with administrative access for emergency situations.
  • Service accounts: Privileged accounts used by applications or services to interact with the operating system.
  • Active Directory or domain service accounts: Accounts enabling password changes and other operations.
  • Application accounts: Used by applications to access databases, run batch jobs, or provide access to other applications.

The Importance of Privileged Access Management

  • Mitigating Insider Threats: Insider threats, which can be unintentional or malicious, pose a significant risk to organizations. PAM ensures that privileged access is granted only to authorized personnel, reducing the chances of internal abuse or data breaches.
  • Securing Critical Systems: Privileged accounts often hold the keys to an organization's most critical systems and data. PAM helps prevent unauthorized access and safeguards against potential cyber threats that target these valuable assets.
  • Compliance and Auditing: Many industry regulations and data protection standards, such as GDPR and HIPAA, mandate strict controls over privileged access. Implementing PAM ensures compliance with these requirements and facilitates auditing and reporting of privileged activities.
  • Credential Theft Mitigation: Cyber attackers frequently target privileged credentials as they represent a high-value target. PAM solutions help protect these credentials from theft and misuse, reducing the risk of unauthorized access.

Strategies for Effective Privileged Access Management

  • Principle of Least Privilege (PoLP): Adhering to the principle of least privilege is a fundamental aspect of PAM. Grant users and systems only the minimal access necessary to perform their specific tasks, reducing the exposure of privileged credentials.
  • Privileged Account Discovery: Begin by identifying and cataloging all privileged accounts in the organization. This includes accounts on servers, databases, applications, and network devices.
  • Privileged Session Monitoring: Implement session monitoring for privileged accounts to record and analyze user activity during privileged sessions. This monitoring allows organizations to detect suspicious behavior and potential security breaches.
  • Privileged Access Segregation: Separate privileged accounts from standard user accounts to prevent unauthorized users from gaining access to sensitive resources. This segregation limits the potential damage from compromised accounts.
  • Multi-Factor Authentication (MFA): Enforce multi-factor authentication for all privileged access attempts. MFA adds an extra layer of security, ensuring that even if credentials are compromised, an additional authentication step is required for access.
  • Just-In-Time (JIT) Privileged Access: Utilize JIT access provisioning to grant temporary and on-demand access to privileged accounts. This minimizes the window of opportunity for attackers while still meeting operational needs.
  • Privileged Access Reviews: Conduct periodic access reviews for privileged accounts to ensure that permissions remain appropriate and relevant. This practice helps identify and address any instances of overprivileged users.
