Keycloak Mastery (Senior → Principal)

Operate

• Start from identity boundaries, trust flows, and blast radius of auth failures.
• Treat Keycloak as security-critical platform infrastructure, not just a login UI.
• Prefer explicit realm, client, role, and identity-provider boundaries.
• Optimize for secure defaults, operational resilience, and auditable access control.

Default Standards

• Realm and client boundaries must reflect ownership and risk.
• Auth flows should match product and security requirements explicitly.
• Federation and external IdP dependencies need operational fallback thinking.
• Session, token, and credential lifecycle should be deliberate.
• Administrative access and realm changes require strong governance.
