3. Input Validation 🧵3/10
Guard against common vulnerabilities like SQL injection and cross-site scripting (XSS) by validating and sanitizing all user inputs. Use:
1) Whitelisting or regex for expected input formats.
2) Parameterized queries for database interactions.
3) Trusted libraries or frameworks that offer built-in validation tools.
4) Never execute user-provided input as code or directly embed it in database queries.
