Contain infrastructure compromise
Cloud identity, secrets, isolation, and zero-trust decisions
Infrastructure security is the control of identities moving through programmable boundaries.
Workloads, people, CI jobs, devices, and vendors receive credentials that authorize actions across networks and control planes. Network location alone is weak evidence; policy should use workload identity, least privilege, short-lived credentials, resource context, and explicit service paths. Segmentation and sandboxing limit blast radius when prevention fails.
Draw who can act on what, through which credential and path, before drawing the network.
A secret manager cannot repair universal permission.
Central storage improves rotation and audit, but a role able to read every secret still creates catastrophic blast radius. Bind secrets to workload identity and purpose, limit retrieval, avoid long-lived export, monitor unusual access, and test emergency rotation. Remove secrets entirely when platform identity can establish trust directly.
The strongest secret is an authority the application never has to possess.
