IAM ensures the right users have the right access to the right resources at the right time. It combines authentication (who you are), authorization (what you can do), and governance (how access is managed and monitored). Modern IAM includes MFA, SSO, RBAC, and policy-based controls, with cloud-native tools like AWS IAM and Azure AD leading the way.
As identity becomes the new perimeter, IAM enables Zero Trust by minimizing privileges and enforcing continuous verification. Best practices include enforcing least privilege, automating provisioning, auditing access, and adopting passwordless authentication. IAM isn’t just about security—it’s a business enabler that reduces risk, ensures compliance, and protects your organization’s digital assets.
