Implement Advanced Security Middleware for Enhanced Request Throttling and CSRF Protection

[aaj89]

###Introduction
Laravel's existing middleware provides essential security features, but with the ever-evolving web security landscape, there's a need for more advanced measures, especially in areas like request throttling and CSRF (Cross-Site Request Forgery) protection.

###Proposed Feature
I propose the development of a new middleware component for Laravel that enhances security features in two key areas:

1. Advanced Request Throttling:

• Current request throttling is effective but can be improved to offer more granular control.
• Implement adaptive throttling based on user behavior patterns and IP reputation.
• Provide options for custom throttling strategies, like progressive delay increments based on request frequency.

2. Enhanced CSRF Protection:

• Extend CSRF protection mechanisms to include additional verification layers, such as checking the origin or referrer headers.
• Introduce a system to identify and handle CSRF token tampering attempts.

###Benefits

• Improved Security: These enhancements will significantly bolster the security of Laravel applications against common threats.
• Customization: Offering customizable options allows developers to tailor security measures to their specific needs.
• User Experience: Adaptive request throttling can improve user experience by differentiating between legitimate users and potential attackers.

###Implementation

• I suggest collaborating with the Laravel community to define the most efficient implementation strategies.
• Prioritize backward compatibility and minimal performance impact.
