# Security in Modern Applications
Security can't be an afterthought. Build it into your development process from the start.
## Authentication & Authorization
**Use Industry Standards**
OAuth 2.0, OpenID Connect, JWT—don't roll your own auth. Use battle-tested libraries.
**Principle of Least Privilege**
Grant minimum permissions necessary. Review and revoke regularly.
## Common Vulnerabilities
- SQL Injection: Use parameterized queries
- XSS: Sanitize user input
- CSRF: Use tokens and SameSite cookies
- Sensitive data exposure: Encrypt at rest and in transit
## Security in CI/CD
- Dependency scanning
- Secret management (never commit secrets!)
- Container image scanning
- Regular security audits
Think like an attacker. Test your defenses continuously.
