What it means
Identity and access management brings together the processes that establish identities, authenticate them, grant permissions, and keep access aligned with changing responsibilities. It includes people, devices, and software workloads. A directory or sign-in product can support IAM, but the operating process extends beyond any single tool.
Think in terms of a lifecycle: an entity joins, its needs change, and eventually its access ends. Each stage requires a trustworthy trigger, an accountable owner, and a way to confirm the resulting access. Governance reviews and privileged-access controls address specialized parts of this larger capability rather than replacing it.
AN ILLUSTRATIVE SCENARIO
A logistics contractor
A logistics firm hires a contractor for a six-week warehouse project. The sponsor requests a named account with access to the relevant warehouse records and a planned end date. The account uses the organization's sign-in process, while the application enforces the approved scope. When the contract ends, the identity system disables sign-in and the application removes local permissions and active sessions as required. A review checks that a separate reporting account was not left behind.
Put it to work
- Map the systems that create identity records, authenticate users, and enforce permissions; identify disconnected applications and nonhuman accounts.
- Define joiner, role-change, and departure workflows with approvals, scoped access, expiry where appropriate, and accountable application owners.
- Reconcile intended access with actual application state, test removal across connected systems, and record exceptions that need manual handling.
How to check your work
Trace a test identity through creation, a role change, and removal. Confirm actual access at the applications after each step and retain evidence of who approved it and which exceptions remain.
Connect the ideas
- Identity
The record an organization uses for a person, device, or workload that can be authenticated.
- Authentication
The act of verifying a claimed identity with authenticators such as passwords, passkeys, or certificates.
- IGA
Processes and tools for reviewing who should have which access and removing what is no longer justified.
- PAM
Controls that broker, record, and constrain powerful administrative identities and sessions.
