What Is Privileged Access Management (PAM)?
3 min. read
Table of Contents
Privileged Access Management (PAM) is a cybersecurity framework and set of technologies that secure, monitor, and control privileged access—the elevated permissions that allow an identity to change system settings, access sensitive data, or administer critical infrastructure. PAM protects the “keys to the kingdom” by vaulting credentials, enforcing least privilege, brokering privileged sessions, and recording activity so attackers (or insiders) can’t quietly turn one compromised account into a full environment takeover.
Key Points
-
Risk reduction: Shrinks the attack surface by minimizing or eliminating standing privileges (always-on admin rights). -
Zero Trust alignment: Treats every privileged request as high risk and continuously verifies identity, context, and device posture. -
Operational visibility: Session logging and recording create a defensible audit trail for incident response and compliance. -
Unit 42 insight: Unit 42 notes that privilege abuse is a common enabler for lateral movement (including cases where excessive privileges are used to move through environments). -
Speed matters: In real intrusions, privilege escalation can happen fast—sometimes in under 40 minutes—which is why just-in-time controls are critical.
Privileged Access Management Explained
PAM is the practice of tightly restricting elevated access to only the people, processes, and systems that truly need it—and only for the time and scope required.
- IAM answers “who are you?”
- PAM answers “what can you do when it really matters?”
PAM creates a controlled layer between an identity and the sensitive resources it administers, ensuring privileged credentials aren’t exposed, reused, or sitting unprotected on endpoints.
Who (and What) is “Privileged” Now?
“Privileged” no longer means only IT admins. It includes:
- Humans: IT admins, help desk, DBAs, security engineers, and high-privilege business users (finance, HR, marketing platforms).
- Non-human identities: service accounts, application accounts, automation scripts, CI/CD pipelines, cloud workloads, API keys, and SSH keys.
These identities often bypass traditional controls and are prime targets for phishing, credential theft, and “living-off-the-land” abuse.
Why PAM Is Critical Today
The traditional network perimeter has dissolved, replaced by a complex ecosystem of cloud services, remote workforces, and interconnected APIs. This shift has turned identity into the new perimeter, making privileged accounts the most lucrative targets for modern adversaries.
Defending Against Credential-Based Attacks
Threat actors prioritize privileged credentials because they provide a direct path to data exfiltration and system sabotage. According to the 2025 Unit 42 Global Incident Response Report, 66% of social engineering attacks specifically target privileged accounts. By securing these credentials in a hardened vault, PAM prevents attackers from using simple phishing or brute-force tactics to gain high-level access.
Meeting Compliance and Regulatory Mandates
Strict regulatory frameworks like GDPR, HIPAA, and PCI DSS require organizations to demonstrate granular control over sensitive data. PAM provides the necessary documentation through automated logging and session reporting. This ensures that every administrative action is traceable to a specific individual, satisfying audit requirements and reducing the risk of heavy non-compliance fines.
Unit 42 Insight: The Speed of Privilege Escalation
Palo Alto Networks Unit 42 researchers have observed that threat actors can move from initial access to full domain administrator status in under 40 minutes. This speed is often achieved using "living-off-the-land" techniques that exploit legitimate system tools. PAM halts this rapid escalation by requiring just-in-time approval and multi-factor authentication for any attempt to elevate permissions.
The Shift to Zero Standing Privileges (ZSP)
Legacy PAM relied on "vaulting" static passwords. Modern security requirements have shifted toward zero standing privileges, where no identity has permanent administrative rights. Instead, access is granted dynamically through Just-in-Time (JIT) elevation and revoked immediately upon task completion.
How PAM Works
PAM functions as a centralized gateway that manages the entire lifecycle of a privileged session. It replaces insecure practices, such as storing passwords in spreadsheets or shared files, with a programmatic and highly audited workflow.
Discovery and Inventory of Privileged Assets
The first phase of a PAM program involves scanning the environment to identify every account with elevated rights. This includes local admin accounts, domain admins, and "shadow" accounts created for temporary projects but never deleted. Establishing a complete inventory is the only way to ensure no "backdoors" remain open for attackers.
The Secure Vaulting Mechanism
Once discovered, privileged credentials are stored in a secure, encrypted vault. Instead of users knowing the actual password, the PAM system provides a temporary token or "injects" the credential directly into the session. This prevents the password from ever residing in the memory of a potentially compromised workstation.
Session Monitoring and Recording
Every time a user accesses a critical system through a PAM gateway, the session is recorded and monitored in real time. This creates a forensic audit trail that can be used to investigate incidents or verify that administrators are following established protocols. Advanced systems can even use behavioral analytics to automatically terminate a session if suspicious activity is detected.
Core Pillars of Modern PAM Strategy
A mature PAM strategy goes beyond simple password management. It integrates deep security principles aligned with a zero trust philosophy.
The Principle of Least Privilege (PoLP)
The principle of least privilege (PoLP) ensures that users are granted the minimum level of access required to perform their job. If a technician only needs to restart a service, they should not have the authority to delete the entire database. PAM enforces this by segmenting permissions based on specific roles and tasks.
Just-in-Time (JIT) Access
JIT access eliminates "standing privileges"—access rights that remain active at all times. Instead, privileges are granted only when a specific task is requested and expire immediately upon completion. This significantly narrows the window of opportunity for an attacker to exploit a valid account.
Privileged Identity Management for Machine Identities
Non-human identities, such as those used by DSPM tools or automated CI/CD pipelines, often hold vast permissions. Modern PAM strategies include secrets management to secure the API keys and SSH keys used by these machines, preventing them from being hard-coded in plain-text scripts.
Strategic PAM Implementation Framework
The table below synthesizes essential PAM controls with strategic implementation steps to help organizations achieve greater resilience against credential-based threats.

Examples of Privileged Access
Human Privileged Access
- Super user account: A powerful account used by IT system administrators that can be used to make configurations to a system or application, add or remove users or delete data.
- Domain administrative account: An account providing privileged administrative access across all workstations and servers within a network domain. These accounts are typically few in number, but they provide the most extensive and robust access across the network. The phrase “Keys to the IT Kingdom” is often used to refer to the privileged nature of certain administrator accounts and systems.
- Local administrative account: This account is located on an endpoint or workstation and uses a username and password. It helps people access and modify their local machines or devices.
- Secure socket shell (SSH) key: SSH keys are heavily used as access control protocols that provide direct root access to critical systems. Root is the username or account that, by default, has access to all commands and files on a Linux or other Unix-like operating system.
- Emergency account: This account grants users administrative access to secure systems in the event of an emergency. It is sometimes referred to as a firecall or break-glass account.
- Privileged business user: Is someone who works outside of IT, but has access to sensitive systems. This could include someone who needs access to finance, human resources (HR) or marketing systems.
Non-Human Privileged Access
- Application account: A privileged account that’s specific to the application software and is typically used to administer, configure or manage access to the application software.
- Service account: An account that an application or service uses to interact with the operating system. Services use these accounts to access and make changes to the operating system or the configuration
- SSH key: (As outlined above). SSH keys are also used by automated processes.
- Secret: Used by development and operations (DevOps) teams often as a catch-all term that refers to SSH keys, application programming interface (API) keys, and other credentials used by DevOps teams to provide privileged access.

Common PAM Challenges and How to Solve Them
Despite its benefits, PAM implementation can face hurdles ranging from technical complexity to user resistance. Addressing these proactively is key to a successful deployment.
Overcoming Admin Friction with Seamless Workflows
Administrators often view PAM as a hindrance to their speed. To solve this, organizations should prioritize solutions that offer a positive user experience, such as single sign-on (SSO) integration and automated approval workflows. When security tools are easy to use, "workarounds" that bypass security are less likely to occur.
Solving the "Shadow Admin" Problem
Users often grant themselves or colleagues temporary high-level access for troubleshooting and then forget to revoke it. Automated discovery and regular access control reviews are essential for identifying and cleaning up unauthorized permissions.
Integrating PAM with Zero Trust Architecture
PAM should not exist in a silo. It must integrate with broader security ecosystems, including secure remote access platforms and SIEM tools. This ensures that identity signals are correlated across the entire network, allowing for faster detection of compromised credentials.
Use Cases & Real-World Scenarios
According to Unit 42 research, threat actors favor previously compromised credentials purchased from initial access brokers. PAM is the primary defense against this tactic.
- Securing the Software Supply Chain: PAM manages secrets used by DevOps pipelines. This prevents attackers from stealing hardcoded credentials to inject malicious code into software updates.
- Mitigating Insider Threats: By enforcing role-based access and monitoring sessions, PAM prevents disgruntled or compromised employees from accessing unauthorized datasets.
- Ransomware Prevention: Unit 42's 2025 Incident Response Report highlights that social engineering often targets help desks to reset administrative passwords. PAM prevents these resets from leading to full network takeover by requiring MFA and approval workflows for all sensitive accounts.
Emerging Trends: Where PAM Is Going
The PAM landscape is evolving to address AI-driven threats and the need for even more frictionless security.
AI-Driven Behavioral Analytics in PAM
Machine learning models are now being used to establish behavioral baselines for privileged users. If an admin who typically logs in from London suddenly attempts to access a sensitive database from a new location at 3:00 AM, the system can trigger an immediate "step-up" authentication challenge or terminate the session entirely.
Moving Toward Passwordless Privileged Access
The ultimate goal of modern identity security is to eliminate passwords. By using biometrics, hardware security keys, and cryptographic passkeys, organizations can remove the risk of credential theft. Passwordless PAM ensures that even if an attacker intercepts a login attempt, they have no "secret" to steal.
Convergence of IAM, IGA, and PAM
The lines between different identity disciplines are blurring. Organizations are moving toward a unified "Identity Fabric" in which general access, governance, and privileged management are handled by a single, cohesive policy engine. This reduces complexity and provides a holistic view of risk across the entire enterprise.
Privileged Access Management FAQs
IAM manages the identity and basic access for all users in an organization, focusing on day-to-day tasks. PAM is a specialized subset of IAM that focuses exclusively on the high-risk, elevated permissions required to manage infrastructure, sensitive data, and administrative configurations.
No. Small and medium-sized businesses are often targeted because they lack robust identity controls. Any organization that manages sensitive customer data or critical infrastructure needs a PAM strategy to prevent unauthorized access.
Yes. By enforcing the principle of least privilege and recording every session, PAM makes it much more difficult for a malicious insider to abuse their authority without being detected. It also prevents "accidental" damage by limiting what a user can do.
Privileged Identity Management (PIM) is often used interchangeably with PAM, but it specifically focuses on identity management. PAM is a broader term that encompasses the tools, processes, and policies used to secure the actual access those identities have.
Modern PAM solutions are cloud-native or hybrid, designed to secure access to AWS, Azure, and Google Cloud consoles as well as the virtual machines and containers running within them. This is often referred to as Cloud Infrastructure Entitlement Management (CIEM).
Regulations such as PCI DSS, HIPAA, and GDPR require strict controls over who can access sensitive data. PAM provides the logs and session recordings necessary to prove to auditors that only authorized individuals accessed regulated systems.
Standing privileges are permissions that are always "on." If a user has an admin account they use once a week, but the account is active 24/7, that is a standing privilege. PAM mitigates this risk by enabling the privilege only when it is requested.
