Identity Federation
Identity & Access Management
Simple
Identity Federation is a building block of "Identity & Access Management". In plain terms: iam, pam, federation, saml/oidc, mfa, zero trust identity, secrets and service accounts. This topic focuses specifically on identity federation and the core ideas you need to understand it.
Technical
Technically, Identity Federation involves the mechanisms, data structures and protocols that underpin identity & access management. You will study how it is implemented, how it is configured, how it fails, and how its behavior shows up in logs, traffic or code.
Why it matters
Identity is the control plane; most breaches involve credential or permission abuse.
Example
In a real organization, professionals working in iam engineering, ad security, cloud identity, soc. rely on identity federation to make decisions — for example, explaining an alert, hardening a system, or writing a finding in a report.
Practice idea
Build a small lab in a VM and experiment with identity federation using the related tools below. Document what you observe.
Deep dive
Read the official documentation and relevant RFCs/standards for Identity Federation. Explore edge cases, internals, and how attackers and defenders view it differently.
