You can never risk it when it comes to the security of your business, and you shouldn’t. Managing access to sensitive information and systems has become increasingly complex. Businesses are dealing with a growing number of users, devices, and applications, each needing specific levels of access.
According to a report,[1] cybercrime is expected to cost the world $10.5 trillion annually by 2025, underlining the essential need for access management. Identity and Access Management (IAM) and Privileged Access Management (PAM) are two vital tools in the security toolkit.
IAM helps organizations control who has access to what within their systems, managing everything from user sign-ins to permissions. On the other hand, PAM focuses on safeguarding the accounts of users with elevated access rights, like administrators, who have the keys to critical systems. Both are important for protecting valuable data and maintaining secure operations.
Whether you’re new to these concepts or looking to refine your existing security measures, this blog will help you easily walk through the complexities of access management.
What is identity access management (IAM)?
IAM stands for Identity and Access Management. It’s a framework that helps businesses manage and secure digital identities and control who has access to resources within their systems. Think of IAM as the gatekeeper of your digital world, ensuring that the right people have the right access to the right resources, and nothing more. With IAM, organizations can manage everything from employee logins to permissions for accessing sensitive data.
IAM is made up of several key features that work together to keep your systems secure:
- Single sign-on (SSO): SSO allows users to log in once and gain access to all the applications and systems they need without having to sign in separately. It simplifies the user experience and reduces the number of passwords people need to remember.
- Multi-factor authentication (MFA): MFA requires users to provide additional verification, such as an OTP code sent to their phone or a fingerprint scan, before gaining access. This is like having an extra layer of security beyond just a password against unauthorized access.
- Role-based access control (RBAC): RBAC ensures that users can only access the information and resources necessary for their specific role within the organization. This helps in minimizing the risk of data breaches and ensuring users have access only to what they need.
- Conditional access management: A key component of Identity and Access Management, conditional access management ensures that the right users, devices, and applications have access to the right resources at the right time. It adds an extra layer of security by evaluating various factors such as user location, device health, and risk level.
IAM and Zero Trust
IAM aligns seamlessly with Zero Trust’s core principle of ‘never trust, always verify,’ as both work together to ensure continuous validation and minimize security risks. Zero Trust carries out authentication where user actions are continuously monitored, flagging suspicious behavior or deviations from normal activity.
With features such as SSO and MFA, IAM works hand-in-hand to enforce the security policies set by Zero Trust principles. By leveraging these principles, it ensures that only compliant, managed devices can have access to corporate emails and work applications.
When Zero Trust and IAM frameworks work together, they create an unbreakable defense against identity-based threats. Zero Trust focuses on continuously verifying access requests, while IAM ensures that only authorized users gain access to the right resources.
Applications and benefits
IAM solutions provide a streamlined approach to user management by automating tasks such as user provisioning and de-provisioning, which helps reduce administrative overhead and ensures that access rights are always up-to-date. For instance, when an employee joins or leaves a company, IAM systems can automatically adjust their access rights, reducing the risk of former employees retaining access to sensitive information and revoking access to them.
Moreover, IAM improves security by providing robust mechanisms for establishing Zero Trust policies for verifying identities and controlling access. By utilizing features like SSO and MFA, Zero Trust further enhances the secure structure of the organization and makes it easier for users to access necessary resources while maintaining strong security controls. This balanced approach not only protects against unauthorized access but also simplifies the user experience.
What is privileged access management (PAM)?
PAM stands for Privileged Access Management. Unlike IAM, which handles user access broadly, PAM focuses specifically on managing and monitoring access for users with elevated privileges. These privileged users, such as system administrators or senior IT staff, have higher levels of access to critical systems and sensitive information. PAM is all about ensuring that these powerful accounts are used responsibly and securely, minimizing the risk of misuse or breach.
PAM includes several features designed to protect and manage privileged accounts effectively:
- Just-in-time (JIT) access: JIT access allows privileged users to gain access to systems only when necessary and for a limited time. This minimizes the risk of potential misuse by ensuring that elevated access is granted only when required.
- Privilege elevation and delegation management (PEDM): PEDM controls how and when users can elevate their access levels. It ensures that privileges are granted only based on need and are managed tightly to prevent unauthorized access. For instance, a user might need temporary admin rights to perform a specific task but should revert to standard access once the task is complete.
- Privileged access security management (PASM): PASM controls and monitors access to critical systems by privileged users. It secures, manages, and audits privileged accounts while tracking activities through session monitoring to create an audit trail for compliance and security. PASM combines access controls, real-time monitoring, and session auditing to protect sensitive systems from misuse and attacks.
Applications and benefits
PAM is essential in scenarios where security is critical, such as managing administrative access to IT systems and protecting sensitive data. For example, in a financial organization, PAM ensures that only authorized personnel can access and manage financial systems, thus safeguarding against potential data breaches. By managing privileged accounts and monitoring their activity, PAM reduces the risk of insider threats and accidental data leaks.
PAM improves overall security by providing granular control over who has access to privileged information or critical systems and when. It helps organizations comply with regulatory requirements by maintaining detailed logs of privileged access and ensuring that elevated rights are used appropriately. This targeted approach to access management ensures that high-risk accounts are protected.
In summary, PAM allows you to enforce policy-based controls over privileged user behavior, specifying which systems authenticated users can access and what actions they can take.
By implementing PAM, you can prevent, detect, and contain privilege-based cyberattacks and security breaches, reducing organizational risk.
IAM vs PAM: Differences and where they diverge
While performing rather similar functions, IAM and PAM vary across several aspects, such as:
- Scope of management: The difference between IAM and PAM primarily lies in their scope of management. IAM takes a broad approach, handling the overall access for all users within an organization. This includes managing credentials, user roles, and access permissions across various systems.
- On the other hand, PAM focuses specifically on users with elevated privileges. It ensures that those with special access rights, such as system administrators, are closely monitored and their access tightly controlled.
- Level of access control: IAM deals with everyday user identities, controlling general access to systems and applications. It manages how users log in, what they can access, and how their permissions are updated.
- PAM, however, is concerned with high-risk accounts that have elevated access rights. It provides enhanced controls for these accounts, ensuring that their elevated permissions are used appropriately and securely.
- Security implications: IAM contributes to an organization’s security by ensuring that users have appropriate access to the resources they need, without unnecessary permissions.
- PAM, meanwhile, addresses higher security risks by focusing on privileged accounts. It improves security through features like session monitoring and just-in-time access, which are important for protecting critical systems and sensitive data.Primary function: IAM’s primary tasks are identifying, verifying, and granting access to various applications and services.
PAM focuses on monitoring and managing access and user activities within sensitive systems.
A brief breakdown of the key differences between IAM and PAM can be viewed as follows:
| Aspect | IAM | PAM |
| Purpose | Authorizing and monitoring network security across the organization | Managing specific users and systems with elevated access for sensitive tasks |
| For whom | Employees, contractors, partners, applications & devices | Admins, IT heads, root users, and powerful service accounts |
| Scope | Almost every user and device across the organization | Users requiring privileged access and elevating current user access to sensitive information |
| Authorization methods | Basic user identification and authorization methods for general access | Advanced methods for securing access to highly sensitive resources |
| Implementation | As early as the foundation for identity security is established | Implemented once critical systems and privileged accounts exist |
| Security function | Focuses on preventing unauthorized access to corporate infrastructure | Prevents misuse or breach of high-risk privileged credentials associated with accessing highly sensitive systems and critical databases |
| Compliance level | General identity governance reports for user access policies | Stronger audit logs and least-privilege enforcement for regulations |
IAM vs PAM: Similarities and where they intersect
Despite their clear differences, IAM and PAM often share similarities and complement each other to boost the secure structure of the organization when implemented together. These similarities include:
- Unified security approach: Although IAM and PAM have distinct roles, they complement each other to create a unified security approach. IAM ensures that all users have the right access levels for their roles, while PAM focuses on securing and managing high-risk privileged accounts. Together, they provide a comprehensive solution for managing and securing access throughout an organization.
- Overlap in functionality: There are areas where IAM and PAM overlap, particularly in enforcing least privilege and monitoring access. For instance, both systems aim to ensure that users only have access to the resources necessary for their roles. While IAM implements this on a broad scale for general users, PAM applies similar principles specifically to privileged accounts, ensuring these high-risk areas are managed with equal diligence.
- Policy enforcement: To work effectively, both PAM and IAM have predefined policies that they implement on the users, especially in scenarios when certain users make important changes to the systems. Well-crafted policies can limit access at specific times, except for urgent situations. IAM and PAM policies execute well in situations when strong protection is needed against potential threats or weaknesses.
Integrating IAM and PAM: A unified approach to security
To effectively protect your business from both internal and external threats, it’s essential to implement both IAM and PAM solutions. By deploying these tools together, you can eliminate vulnerabilities within your system.
Integrating IAM and PAM provides a comprehensive security approach that not only regulates access and passwords but also closely monitors user activities and facilitates faster auditing of all accounts. Combining IAM and PAM creates layered security, ensuring all access points are monitored and secured, reducing risks of unauthorized access.
Utilizing the best of both worlds for more secure access
As we’ve explored, PAM is not a standalone tool but rather a specialized subset of IAM, focusing specifically on privileged accounts. The integration of both IAM and PAM is essential for crafting a robust access management strategy. Incorporating both IAM and PAM into your security framework ensures that every layer of access is thoroughly managed and access to sensitive resources is secured.
This dual approach streamlines access management and also strengthens your business’s defenses against both internal and external threats.
Ultimately, the true strength of your security strategy lies in how well these two systems work together. By leveraging the full capabilities of both IAM and PAM, you can create a unified, comprehensive approach to access management that minimizes risks and ensures the integrity of your digital assets.

FAQ
1. How do IAM and PAM work together to enhance security?
IAM (Identity and Access Management) and PAM (Privileged Access Management) work together to enhance security by managing who can access what. IAM makes sure users have the right permissions for regular tasks, while PAM focuses on controlling and monitoring accounts with special, higher-level access. Together, they protect sensitive information and reduce the risk of unauthorized access.
2. Can IAM replace the need for PAM in an organization?
No, IAM can never replace the need for PAM since they both serve different purposes. IAM manages overall user access, while PAM specifically secures and monitors privileged accounts with elevated access, making both essential for comprehensive security.
3. What are some best practices for implementing IAM and PAM solutions?
To effectively use IAM and PAM, regularly review user access, enforce strong password policies, and enable multi-factor authentication. Additionally, privileged accounts must be monitored closely and access based on specific roles and needs must be limited.
4. How does Role-Based Access Control (RBAC) relate to IAM and PAM?
Role-Based Access Control (RBAC) is an essential framework for both IAM and PAM. In IAM, RBAC is used to manage general user access across systems and applications, ensuring users only have access to the resources they need. In PAM, RBAC specifically governs privileged access, restricting and monitoring elevated permissions for sensitive systems or data, helping minimize security risks associated with high-level access.
5. What are the potential risks of not implementing PAM alongside IAM?
Without PAM alongside IAM, privileged accounts can go unmonitored, leaving them vulnerable to misuse or compromise. While IAM handles general access, it doesn’t provide the controls needed for sensitive data and systems. Without PAM, organizations are at a higher risk of data breaches and unauthorized access.
6. When to use IAM and when to use PAM?
Use IAM when you need to manage general user identities, logins, and access across systems—like employees accessing email, internal tools, or cloud apps. IAM ensures everyone gets the right access based on their role. Use PAM when you’re dealing with users who have elevated privileges—like system admins or IT staff who can change configurations, access critical infrastructure, or handle sensitive data. PAM adds extra layers of control and monitoring for these high-risk accounts. Think of IAM as securing everyone’s access, while PAM secures the most powerful access.
