## Description

This project provides a comprehensive security framework for PHP applications, designed to manage the entire lifecycle of user authentication and authorization. It functions as a middleware layer that intercepts incoming HTTP requests to enforce security policies, resolve user identities, and maintain persistent sessions across web interactions.

The framework distinguishes itself through a modular, event-driven architecture that integrates directly into the application lifecycle. It supports diverse authentication methods, including standard form-based logins, API bearer tokens, and federated identity integration via OpenID Connect and OAuth. Authorization is handled through a flexible system that combines role-based access control with attribute-driven metadata, allowing developers to define granular permissions and custom logic directly on controller methods.

Beyond core identity management, the library includes protective utilities to mitigate common web vulnerabilities. It provides built-in mechanisms for cross-site request forgery protection, login rate limiting to prevent brute-force attacks, and secure session termination directives. The framework also facilitates automated security auditing by scanning project dependencies for known vulnerabilities.
