Dynamic Firewall Manager

The Dynamic Firewall Manager is a C++-based project that allows dynamic management of firewall rules on Linux-based systems. It enables users to add, remove, and view firewall rules programmatically using use-case-specific scenarios. This project leverages D-Bus for inter-process communication (IPC) to provide a flexible and efficient interface for managing firewall rules.

Features

• Dynamic Rule Management:

  • Add firewall rules dynamically based on use cases.
  • Remove specific or all rules with ease.
  • View active rules currently applied to the system.

• Use-Case Flexibility:

  • Manage rules tailored to specific application or network scenarios.

• Linux Integration:

  • Uses Linux’s native iptables or nftables for rule management.

• D-Bus IPC:

  • Inter-process communication for interacting with the firewall system.
  • Allows multiple applications to request and manage firewall rules.

---

Requirements

• Operating System: Linux (any modern distribution supporting iptables or nftables)
• Dependencies:
  • G++ or Clang compiler
  • CMake for build configuration
  • D-Bus development libraries (libdbus-1-dev)
  • iptables or nftables installed on the system

Architecture

Core Components:

1. Rule Manager:

   • Implements logic for adding, removing, and listing firewall rules.
   • Interfaces with iptables or nftables commands.

2. D-Bus IPC:

   • Provides an IPC layer for communication.
   • Exposes APIs for external applications to interact with the firewall.

3. CLI Interface:

   • User-friendly command-line interface for managing rules.
   • Parses and executes user commands.
