A comprehensive overview of Rails security features from version 1 through 8.1.3, covering built-in protections (CSRF, XSS, SQL injection, strong parameters, encrypted credentials, rate limiting) and what remains the developer's responsibility (authorization, 2FA, audit logging, OAuth, account lockout). Includes a production security checklist, a timeline of security features per Rails version, and recommended gems for gaps not covered by Rails core like Pundit, Devise, and rack-attack. Emphasizes that missing authorization on tenant-scoped data is the most common serious Rails security bug.
