Application security encompasses practices and measures that protect software from threats, including data encryption, input validation, and vulnerability prevention.
Why It Matters
Security breaches can destroy customer trust, result in regulatory fines, and cost more to fix than building security in from the start.
When to Use This
- Encrypting sensitive data at rest and in transit
- Validating and sanitizing user input
- Preventing SQL injection and XSS attacks
- Implementing proper access controls
Examples
- HTTPS enforcing encrypted connections
- Password hashing so even DBAs cannot read passwords
- Input validation preventing malicious code injection
