Understanding IAM
The 3 Pillars of IAM — and How They Build Zero Trust
IAM isn't one thing — it's three distinct disciplines working together. IGA governs who should have access. AM controls how they authenticate. PAM secures the most dangerous accounts. Together, they form the foundation of a Zero Trust architecture.
Zero Trust = IGA + AM + PAM working together
Zero Trust is not a product — it's a strategy built on "never trust, always verify." IGA ensures only the right people have access. AM verifies identity at every login. PAM locks down privileged accounts. When all three are mature, you have a true Zero Trust posture: no standing access, no implicit trust, and full auditability.
IGA
The Rules EngineIdentity Governance & Administration
IGA defines who should have access to what — and enforces it through policy. It handles the full identity lifecycle: joiner, mover, leaver (JML) processes, role-based access control (RBAC), access certifications, and segregation of duties (SoD). Think of IGA as the governance layer that answers "does this person still need this access?"

The Fastest Growing Attack Surface
Non-Human Identities (NHI)
Service accounts, API keys, OAuth tokens, and CI/CD credentials outnumber human identities 45:1 in most enterprises — and they're the #1 attack vector in modern breaches. NHI security is the next frontier of IAM.

What is NHI?
ConceptNon-Human Identities (NHIs) are machine accounts — service accounts, API keys, OAuth tokens, CI/CD pipeline credentials, and cloud workload identities. They outnumber human identities 45:1 in most enterprises and are the #1 attack vector in modern breaches.
OWASP NHI Top 10
FreeThe OWASP Non-Human Identities Top 10 is the definitive reference for NHI security risks. Covers improper offboarding, secret sprawl, overprivileged service accounts, and insecure CI/CD credentials.
Secrets Management (HashiCorp Vault)
FreeHashiCorp Vault is the industry standard for managing NHI secrets at scale. Free training available via HashiCorp Learn — covers dynamic secrets, PKI, and Kubernetes auth methods.
AWS IAM Roles & Service Accounts
FreeAWS's official documentation on IAM roles, instance profiles, and service-linked roles. Essential reading for cloud engineers managing NHIs in AWS environments.
Pro tip: Get a free sandbox first
Every major IAM platform offers a free developer tenant or trial environment. Before spending money on a course, spin up a free sandbox and build something real — hands-on experience is what employers actually test in IAM interviews.
