Security at Scale¶
Reduce attack paths through explicit identity, least privilege, encryption, abuse controls, and verified supply chains.

| Level | Guide | You are done when |
|---|---|---|
| Junior | Protect one service | You can manage secrets, authentication, authorization, and safe transport. |
| Middle | Threat-model boundaries | You can design tokens, PKI, KMS, and abuse controls. |
| Senior | Secure a system | You can apply zero trust, supply-chain controls, and layered defense. |
| Professional | Build security capability | You can govern identity, keys, policy, detection, and response at scale. |
Practice rule¶
Authenticate identity, authorize every action, minimize privilege, and assume every boundary can be abused.
