The terminal waits. You type a command. A wall of text floods the screen — the manpage. Dense, authoritative, and buried in syntax. Hidden inside is knowledge that defines how systems behave, but it lives apart from your code, locked in static documentation. That separation is a security gap.
Manpages as Security as Code is the practice of turning those static descriptions into executable, enforceable, and version-controlled policy. Instead of passively reading rules, you codify them. You integrate them directly into pipelines, CI/CD, and runtime checks. This makes manpage-defined behavior part of the codebase, subject to the same rigorous review, test coverage, and continuous monitoring as any feature.
When manpages describe file permissions, cryptographic requirements, input validation rules, or network configurations, they provide a blueprint for security. But unless those requirements are implemented as code, they are ephemeral. Security as Code means committing those requirements to source control. It means automating enforcement so the documented security model is always live, always tested.
The workflow starts with manpage parsing. Extract commands, flags, and environmental variables tied to security outcomes. Model them in code — using lint rules, scripts, or policy agents. Link them to deploy environments so every build validates compliance against the manpage specification. This is applicable to ssh, openssl, sudo, system calls, kernel parameters — anywhere manpages define safe defaults and edge cases.
