Identity and Access Management (IAM)
What is Identity and Access Management (IAM)?
Identity and Access Management, or IAM, is the set of processes, policies, and technologies used to identify users and systems, verify who they are, and control what resources they are allowed to access.
Examples
- A company uses IAM to require employees to sign in with multifactor authentication before accessing cloud applications.
- An organization assigns users to roles so finance staff can access payroll systems while other departments cannot.

Modern organizations depend on thousands of access decisions every day. Employees sign in to email, administrators manage servers, apps connect to databases, contractors use shared platforms, and customers access online accounts. Every one of those actions raises the same basic question: who should be allowed in, and what should they be able to do once they get there?
IAM exists to answer that question in a structured way. Without it, access becomes inconsistent, excessive, and difficult to track. People may keep accounts they no longer need, sensitive systems may be exposed to the wrong users, and investigations become harder because nobody is certain who had access to what. Good IAM turns identity and access from a loose collection of logins into a managed security discipline.
Summary 📝
IAM is the discipline of managing identities and controlling access across systems, applications, and data. It covers authentication, authorization, account life cycle management, and access governance. Its value comes from making digital trust structured, measurable, and easier to defend instead of leaving access decisions scattered and inconsistent.
