Security Examples - OWASP and Security Best Practices
Explore security examples for web applications. OWASP Top 10, encryption, authentication and authorisation — practical applications.
Security is not an add-on but part of the design. From SQL injection prevention to secure session storage — these examples show how companies proactively address vulnerabilities.
Prepared statements and parameterisation against SQL injection
A financial platform replaced string concatenation with prepared statements. All user input is parameterised and validated.
- Parameterised queries in all database calls
- Input validation with whitelist
- Minimal error messages to the user
JWT with refresh tokens and secure cookie storage
A SaaS application uses short-lived access tokens with HTTP-only secure cookies for refresh. XSS risks are minimised.
- Access token 15 min, refresh token 7 days
- HTTP-only, Secure, SameSite cookies
- Token rotation on refresh
Key takeaways
- Prepared statements and parameterisation eliminate SQL injection.
- HTTP-only cookies for tokens prevent XSS theft.
- Regular dependency scanning and penetration tests are essential.
