🔒 Input Validation
Always validate and sanitize user inputs to prevent injection attacks. Use libraries like OWASP Validated to ensure data integrity.
🔑 Password Handling
Store passwords using strong hashing algorithms (e.g., bcrypt, Argon2). Never store plain text.
🛡️ Prevent XSS
Escape user-generated content before rendering it in HTML. Use Content Security Policy (CSP) headers to mitigate risks.
💻 Avoid SQL Injection
Use parameterized queries or ORM tools to separate SQL code from user input.
🔄 Regular Updates
Keep dependencies and frameworks up to date to patch known vulnerabilities.
