In today's digital landscape, security is not just an add-on feature but a fundamental aspect of web development. This post explores essential practices for building secure web applications.
Input Validation and Sanitization
One of the most critical aspects of web security is proper input validation and sanitization. Never trust user input, always validate and sanitize it server-side.
// Example of input validation
function validateInput(input: string): boolean {
return /^[a-zA-Z0-9]+$/.test(input);
}Key Security Practices
- Implement proper authentication and authorization
- Use HTTPS everywhere
- Keep dependencies updated
- Implement CSP (Content Security Policy)
- Use secure session management
