The Next-Generation Firewalls are advanced cybersecurity solutions in the cybersecurity realm. The primary goal of this project is to enhance the security posture of an organization or network by implementing advanced threat prevention mechanisms. This firewall configuration is suitable for small to large scale networks where security and network performance is a demand. This firewall has been configured with advanced rules to prevent restricted and controlled access to packets flowing through the network interface.This firewall uses Advanced Network Intrusion Detection system powered by Suricata, which uses both Signature based detection as well as Heuristic Analysis in Legacy mode, which also has upto 13 levels of verbosity for easy administration of the network and to prevent Advanced Persistent Threats and access to the systems.Equipped with an User-Friendly Interface, the firewall is easier to manage and scale on a large network. With the help of Virtualization Techniques this firewall can be implemented for perimeter security as well as specific purpose utility such as Cloud Server security. With the help of Web Portal for management the user is not intended to be physically present on the site of deployment for managing the Firewall. With the help of VPN service the users can remotely access the network which is currently being prioritized by most IT industries.
