Authentication and Authorization Security
Laravel provides robust authentication mechanisms, but proper implementation is crucial. Always use Laravel's built-in authentication features, implement proper password policies, enable two-factor authentication where possible, and regularly audit user permissions. Never store passwords in plain text and always use Laravel's Hash facade for password hashing.
Data Protection and Encryption
Protect sensitive data using Laravel's encryption features. Use HTTPS for all data transmission, encrypt sensitive database fields, implement proper session management, and ensure that API endpoints are properly secured with rate limiting and authentication tokens.
Input Validation and SQL Injection Prevention
Always validate and sanitize user input using Laravel's validation rules. Use Eloquent ORM or Query Builder to prevent SQL injection attacks, implement CSRF protection on all forms, and sanitize data before displaying it to prevent XSS attacks. Regular security audits and dependency updates are essential.
