PIM vs. PAM Security: Understanding the Difference

Summary: Understanding the nuances of privileged access management vs privileged identity management can be challenging. Although PIM and PAM are often used interchangeably, there is an important difference between PIM and PAM that companies should know. In this article, we’ll explain PIM vs PAM and explore how they work to demonstrate the differences between them. By the end of this article, you’ll know what role PIM and PAM should play in your security strategy.

What are PIM and PAM?

Almost every organization uses identity and access management (IAM) strategies or tools as part of its security practices. IAM is the overarching term to describe how companies manage user identities, authenticate users, and control access to company resources. Privileged identity management (PIM) and privileged access management (PAM) are subsets of IAM.

PIM and PAM address how companies manage who can access a company’s most critical resources, like servers, databases, applications, and Kubernetes clusters. They operate under the principle of least privilege to limit who and how many users can access secure systems and the sensitive data stored within.

What is privileged identity management (PIM)?

Companies often control login access by maintaining a directory of privileged user identities and what resources those identities have access to based on role-based or attribute-based access controls. Privileged identity management (PIM) is the process companies use to manage which privileged users—including human users and machine users—have access to which resources.

PIM security policies often focus on controlling users with elevated permissions to change settings, provision or deprovision access, and make other significant changes without formal oversight. Some companies use PIM solutions to monitor user behavior and distributed access to prevent admins from having too many permissions.

What is privileged access management (PAM)?

Each privileged user within a directory is permitted access to some resources based on role-based or attribute-based access controls. Privileged access management is the process of controlling and monitoring access to critical company resources, often using identity and access management technologies.

Companies use PAM solutions to manage credentials, authenticate user identities when a user tries to access a company resource, and provide just-in-time access to identities that normally can’t access certain resources. Often, PAM tools also offer detailed session monitoring and access logs to help companies report on usage patterns and meet compliance standards.

💡Make it easy: Just-in-Time Access works best when it is easy for the end user to request and receive access. It should also be auditing to map the end-to-end chain of events, who is requesting access, why they are requesting it, and for how long. Play the video below to see how easy StrongDM makes Just-in-Time access, and try it yourself.

 

PIM vs. PAM: What's the Difference?

The main difference between PIM and PAM is that PIM addresses what access a user is already granted, while PAM addresses how to monitor and control access whenever a user requests access to a resource.

PIM focuses on resource management and defining which roles or attributes determine that a user gains access to particular resources. For example, determining which resources a new employee needs access to during onboarding is a PIM-related policy.

Meanwhile, PAM focuses on the security policies and tools that help companies store and encrypt credentials, validate if users are permitted to access certain resources, and provide a secure way for approved users to access critical systems, tools, and data. PAM solutions help teams maintain least-privilege policies by allowing teams to temporarily provision access to support user workflows without unnecessarily creating new static user credentials.

PIM vs. PAM Comparison Table

PIM PAM
  • Emphasizes resource management
  • Focuses on which user identities receive which access rights
  • Determine the parameters of what access is necessary for each user identity based on certain roles or attributes
  • May focus on distributing access to prevent superusers or admins from having too much power
  • Emphasizes securing resources by ensuring only certain validated identities can access those resources
  • Focuses on monitoring capabilities to prevent unauthorized access
  • Determines how to validate user identities, provide secure access to resources, and provision just-in-time escalated access for users that would not normally have access

PIM and PAM: How Do They Work?

Rather than comparing privileged access management versus privileged identity management, it’s more valuable to consider how PAM and PIM complement each other. Many PAM solutions are already designed to support PIM policies and management.

PIM/PAM security starts with finding the right tools to manage resources and user identities within your organization. A PIM/PAM solution works by connecting with a user directory—which contains all applicable users, their existing permissions, and their encrypted user credentials—to a resource management platform. Often, these solutions let users use a single sign-on application to log into resources they are allowed to access through a secure gateway.

The secure gateway confirms the identity has access to the requested resource and allows the authenticated user to use the resource, logging each interaction as it occurs. If the identity doesn’t have the right permissions to access a resource, admins can provide temporary credentials through their PAM solution. By limiting how many users have constant access to resources, companies can reduce the likelihood of a breach.

Introducing DAM: How Is It Different From PIM and PAM

PIM and PAM focus specifically on managing and controlling access to privileged accounts and sensitive systems. However, organizations need to also ensure that access is only available in the moments it is needed and that that access is secure and auditable. Dynamic Access Management (DAM) enables this approach by delivering just-in-time access and eliminating always-on credentials through Zero Standing Privileges.

💡Glossary term: Dynamic Access Management (DAM) is the concept that credentials and access should only exist in the moments they are needed, and that access must be secure and auditable.

Dynamic Access Management has four key attributes:

Where PIM and PAM are focused solely on privileged accounts, DAM extends the secure authentication, authorization, and auditing capabilities to all technical users. It also greatly simplifies the process of access infrastructure, helping to make technical employees more productive while continuing to deliver a high level of security.
