Security

This skill provides guidance on writing secure code and identifying security vulnerabilities during code review.

Core Principles

  • Defense in Depth: Layer multiple security controls; don't rely on a single defense
  • Least Privilege: Grant minimum permissions necessary for functionality
  • Don't Trust Input: Validate and sanitize all external input
  • Keep It Simple: Complex code is harder to secure
  • Fail Secure: When errors occur, fail closed rather than open
