Session management and secure cookies (rotation, fixation, timeouts, theft detection).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
rule_id: codeguard-0-session-management-and-cookies ## Session Management & Cookies Implement robust, attack-resistant session handling that prevents fixation, hijacking, and theft while maintaining usability. ### Session ID Generation and Properties - Generate session IDs with a CSPRNG; ≥64 bits of entropy (prefer 128+). Opaque, unguessable, and free of meaning. - Use generic cookie names (e.g., `id`) rather than framework defaults. Reject any incoming ID not created by the server. - Store all session data server-side; never embed PII or privileges in the token. If sensitive, encrypt server-side session store at rest. ### Cookie Security Configuration - Set `Secure`, `HttpOnly`, `SameSite=Strict` (or `Lax` if necessary for flows) on session cookies. - Scope cookies narrowly with `Path` and `Domain`. Avoid cross-subdomain exposure. - Prefer non-persistent session cookies (no Expires/Max-Age). Require full HTTPS; enable HSTS site-wide. Example header: ``` Set-Cookie: id=<opaque>; Secure; HttpOnly; SameSite=Strict; Path=/ ``` ### Session Lifecycle and Rotation - Create sessions only server-side; treat provided IDs as untrusted input. …

How to install
mdr add santosomar/ai-agents-for-cybersecurity/.cursor/rules/codeguard-0-session-management-and-cookies.mdc@sha256:2064404d594a9f04The line at the top of this page pins the label v1.5.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
