01
The security sequence
A resilient system distinguishes identity from authentication, authentication from authorization, authorization from access control, and access control from monitoring and recovery.
02
Failure is part of design
A system with strong authentication but no recovery architecture may still fail. Security design should consider technical disruption, data corruption, communication interruption, physical disruption, and human error.
03
Protection without promises of perfection
No infrastructure can guarantee that nothing will fail. The honest objective is to reduce unnecessary exposure, detect problems, recover responsibly, and learn from what happened.
