Identity and Access Management (IAM) is a framework of technologies, policies, and processes that helps organizations manage digital identities and control access to applications, systems, and data. IAM ensures that the right users have the appropriate access to the resources they need at the right time. It includes authentication, authorization, Single Sign-On (SSO), Multi-Factor Authentication (MFA), user provisioning, and access management.
For businesses using cloud applications and enterprise systems, IAM is an essential part of cybersecurity. Understanding IAM is also a valuable starting point for people interested in identity administration, cybersecurity, and Okta training.
What Is Identity and Access Management Used For?
Identity and Access Management helps organizations control who can access their digital resources and what actions they can perform. As businesses use more applications, databases, cloud platforms, and remote work systems, managing user access manually becomes increasingly difficult.
IAM provides a structured approach to managing identities and permissions throughout the user lifecycle. Common IAM use cases include:
- Employee access management: Giving employees access to the applications required for their jobs.
- Authentication: Verifying the identity of users before allowing them to sign in.
- Authorization: Determining which resources and actions an authenticated user is permitted to access.
- Single Sign-On: Simplifying access to multiple integrated applications.
- Multi-Factor Authentication: Adding additional verification to help protect accounts.
- User provisioning and deprovisioning: Creating, updating, and disabling accounts as user requirements change.
- Access governance: Reviewing permissions and maintaining appropriate access controls.
For example, when a new employee joins a company, an IAM system can help provide access to email, HR software, and approved business applications. When the employee changes roles or leaves the organization, their permissions can be updated or removed.
How Does IAM Work?
IAM works by combining identity information, authentication methods, access policies, and authorization controls. The exact process varies depending on the organization's systems and IAM solution. Here is a simplified explanation of how IAM works.
Step 1: Create a Digital Identity
The process begins when an organization creates a digital identity for a person, service, or other entity that needs access to its resources. For an employee, the identity may contain information such as a username, email address, department, job role, and group membership.
This information helps the organization identify the user and determine which resources may be relevant to their responsibilities.
Step 2: Authenticate the User
When the user attempts to sign in, the IAM system verifies their identity using configured authentication methods. These methods may include passwords, authenticator applications, security keys, passkeys, or supported biometric authentication.
Organizations may also require Multi-Factor Authentication (MFA), which adds another verification step to strengthen account protection.
Step 3: Evaluate Access Permissions
After successful authentication, the system determines whether the user is allowed to access the requested application or resource. For example, a finance employee may be permitted to access accounting software, while a marketing employee may have access to campaign management tools.
Access decisions depend on assigned permissions, applicable policies, and the resource being requested.
Step 4: Grant or Deny Access
The IAM system or connected application applies the relevant access rules. If the request meets the required conditions, access is granted. Otherwise, the request is denied.
A user may be able to sign in successfully but still be denied access to a particular file, application, or administrative function. This distinction is important because verifying a user's identity does not automatically mean that the user should have unrestricted access.
Step 5: Monitor and Review Access
IAM also supports ongoing access management. Organizations can review permissions, monitor sign-in activity, investigate suspicious behavior, and adjust access when job responsibilities change.
Regular access reviews help identify unnecessary permissions and reduce the risk of accounts retaining access they no longer need.
What Are the Main Components of IAM?
Understanding the core components of IAM makes it easier to see how identity management works in real-world environments.
1. Identity Management
Identity management involves creating, maintaining, and updating digital identities. It includes managing user profiles, group memberships, roles, and identity attributes. For example, when an employee moves from sales to finance, their identity information and application assignments may need to be updated.
2. Authentication
Authentication verifies that a user or system is who or what it claims to be. Common authentication methods include passwords, passkeys, security keys, certificates, and MFA. Strong authentication helps reduce the likelihood of unauthorized users accessing protected resources.
3. Authorization
Authorization determines what an authenticated identity can access and which actions it can perform. For example, an employee might be allowed to view a report but not modify or delete it. An administrator may have additional permissions to manage users or configure applications.
4. Single Sign-On (SSO)
Single Sign-On allows users to authenticate through a central identity provider and access multiple integrated applications without repeatedly entering their credentials. For example, an employee may sign in through an organizational identity platform and then access supported CRM, collaboration, and HR applications.
SSO can improve the user experience while helping IT teams centralize authentication policies.
5. Multi-Factor Authentication (MFA)
MFA requires users to verify their identity using multiple types of authentication factors. These factors generally include something the user knows, something they possess, or something they are. Using independent factors helps provide stronger protection than relying only on a password.
6. User Provisioning and Deprovisioning
Provisioning involves creating accounts and assigning appropriate access in connected systems. Deprovisioning involves removing or disabling accounts and permissions when access is no longer required. Depending on the platform and integration, these processes can be automated to reduce repetitive administrative work and help prevent outdated access.
7. Access Governance and Auditing
Access governance helps organizations determine whether permissions remain appropriate. It can include access reviews, approval workflows, policy enforcement, and reporting. Audit records can help security teams investigate events, demonstrate control processes, and identify potential access-related issues.
What Are the Benefits of IAM?
Organizations implement IAM to strengthen access controls and simplify identity-related operations.
- Improved security: Authentication policies and controlled permissions help reduce unauthorized access risks.
- Centralized access management: IT teams can manage identities and access policies more consistently across supported systems.
- Better employee productivity: SSO and automated provisioning can simplify access to approved applications.
- Reduced manual work: Lifecycle automation can help streamline account creation, updates, and deactivation.
- Support for compliance: Access records, permission reviews, and documented policies can help organizations demonstrate relevant security controls.
- Consistent user lifecycle management: Organizations can adjust access as employees join, change roles, or leave.
However, IAM does not guarantee complete security on its own. Organizations must configure it correctly, review permissions regularly, protect privileged accounts, and monitor suspicious activity.
What Are the Common IAM Tools?
Several platforms provide identity and access management capabilities. The best choice depends on an organization's applications, security requirements, existing infrastructure, and budget. Examples include:
- Okta: Provides identity and access management capabilities, including SSO, MFA, and lifecycle management.
- Microsoft Entra ID: Supports identity, authentication, and access management across Microsoft and integrated environments.
- AWS Identity and Access Management (AWS IAM): Manages access to AWS resources using identities, roles, and policies.
- Ping Identity: Provides identity and access management solutions for workforce and customer use cases.
These platforms do not all serve identical purposes or offer the same features. For instance, AWS IAM focuses on controlling access to AWS resources, while workforce identity platforms can support sign-in and application access across a broader set of business systems.
