Building Security In
Security should be part of the development process from the start, not added as an afterthought.
Secure Coding Principles
Blacklist
→ Validate type, length, range, format
Output Encoding:
→ Encode data before displaying
→ Context-appropriate encoding (HTML, JS, URL, CSS)
Error Handling:
→ Never expose stack traces to users
→ Log detailed errors server-side
→ Return generic error messages
Least Privilege:
→ Run with minimum necessary permissions
→ Database users with limited access
→ File system permissions
