Rails Security Baseline

Category: Security  ·  Sub-category: web-security  ·  Last updated:
lang:rubytype:audittype:review
Security baseline for Ruby on Rails 8 apps — strong params (and their common bypass mistakes), CSRF for browser apps, CSRF for SPAs, Brakeman + bundler-audit + Dependabot, Rails credentials per environment, JWT best practices (short-lived + refresh rotation, never put secrets in payload), CORS without wildcards, Rack::Attack for rate limiting and brute-force, OWASP Top 10 mapped to Rails. Use when reviewing or writing any controller, when the user mentions security, CSRF, params, mass assignment, secrets, credentials, JWT, CORS, Brakeman, bundler-audit, OWASP, secure headers, content security policy, or asks "is this safe to ship". Use proactively before any commit that touches auth, params, or external input.
