Episode notes
A Career Rooted In Hands-On Identity
- Felix traced his identity career from Unix at 17 through LDAP, virtual directories, and analyst roles at Forrester and Gartner.
- He now focuses on writing and thinking deeply about machine identity after a long technical career.
Machines Run The Business Now
- The majority of critical business processes are machine-to-machine interactions that traditional human-focused IAM can't secure effectively.
- Modern machine identity must remove static credentials and enable secure dynamic interactions instead of managing more technical debt.
Ephemeral Identities Beat Accounts
- Machines don't need long-lived accounts or MFA like humans; treat identity as ephemeral when possible.
- Embed identity in the workload lifecycle so identities appear on start and vanish on stop.
