Configuration management is covere...
Feb 23, 2026•15 min•Ep. 45
This episode teaches secrets management as an operational system that must be designed for lifecycle control, because SecurityX questions often focus on the real causes of compromise: leaked tokens, unmanaged keys, stale credentials, and “temporary” secrets that become permanent. You’ll define the major secret types—passwords, API tokens, certificates, encryption keys—and learn how their threat models differ, including how tokens can bypass MFA, how certificates fail catastrophically when privat...
Feb 23, 2026•15 min•Ep. 43
This episode prepares you to troubleshoot enterprise IAM failures the way SecurityX expects: by isolating the decision point that denied or allowed access and tracing the identity signal path from user to resource. You’ll review conditional access as a policy engine that blends identity, device posture, location, and risk signals, then learn how failures appear when signals are missing, mis-scored, or applied inconsistently across apps. Federation is covered through practical SAML and OAuth flow...
Feb 23, 2026•15 min•Ep. 42
