Evolution of Identity Access Management (IAM)

Key Components of IAM

Identity Access Management (IAM) is built upon several key components that work together to ensure secure and efficient access control within an organization. Understanding these components is crucial for implementing a robust IAM strategy.

  • Identification is the process by which a system recognizes an individual. This usually involves a username or ID number that the user claims as their identity.
  • Authentication is the verification of the claimed identity. This is typically achieved through passwords, biometric data, smart cards, or other methods that can prove the user is who they claim to be.
  • Authorization determines what resources the user is allowed to access and what operations they are permitted to perform. This is often managed through policies and rules set by the organization.

What are Directory Services?

Directory services play a crucial role in IAM by serving as repositories that store and manage information about users, including their access rights, group memberships, and profile data. These services allow for centralized management of user information, making it easier to enforce security policies and access controls.

Common Directory Services Protocols

The two common directory services protocols are mentioned below –

LDAP (Lightweight Directory Access Protocol)

  • LDAP is an open, vendor-neutral application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.
  • It’s used to find information about organizations, individuals, and other resources such as files and devices in a network, whether on the public Internet or a corporate intranet.

Active Directory (AD)

  • Developed by Microsoft, Active Directory is a directory service specifically for Windows domain networks.
  • It uses domain controllers to authenticate and authorize all users and computers in a Windows domain-type network—assigning and enforcing security policies for all computers and installing or updating software.
