Hybrid Security Framework Integrating Firewall and VPN Technologies

The proposed solution introduces SunduVault, which is a cloud-based management framework for managing a WireGuard-based virtual private network with a firewall management panel. End-to-end secure connection to the network is enabled by a PHP/MySQL backend that is responsible for handling user authentication, assigning dynamic IPs, and managing peer onboarding using a REST API. A peer monitoring dashboard along with firewall management capabilities gives live status of connections between clients and the central server, allowing the administrator to apply access control policies without requiring shell-level access. Secure access to the application is ensured by session-based authentication coupled with automatic token refresh, peer metadata storage in MongoDB, and separation of roles among admin and user portals. Experimental results show successful integration of peer onboarding and network segmentation using firewall rules along with real-time peer monitoring dashboard running at under one second refresh intervals.
