Best Practices for Protection

1. التحقق من المدخلات (Input Validation)
   • o Ensure all user input is validated before processing.
   • o Use libraries such as Laravel Validation أو Express Validator.
2. إدارة الجلسات (Session Management)
   • o Use Secure Cookies وHttpOnly Flags to prevent unauthorized access.
3. التشفير (Encryption)
   • o Use HTTPS (SSL/TLS) for all communications.
   • o Store passwords using Hashing methods like bcrypt أو Argon2.
4. التحكم في الصلاحيات (Access Control)
   • o Prevent users from accessing data or functions they are not authorized for.
   • طبّق Role-Based Access Control (RBAC).

Code Examples

php

CopyEdit

// Laravel Example for Input Validation

]);

javascript

CopyEdit
