This commit introduces substantial enhancements to both the NetworkingGenie class and the Utilities module, focusing on the secure usage of sudo permissions, improved error handling, and the creation of new sudo methods.
1. Secure Sudo Usage: The `use_sudo` method from the Utilities module is now integrated within the `find_main_interface`, `create_dummy_interface`, and `setup_traffic_mirroring` methods of the NetworkingGenie class. This method ensures that commands requiring sudo permissions are executed securely. It achieves this by encrypting the sudo password, using it for the required command, and then immediately clearing it from memory. This approach significantly enhances the security of operations that require elevated permissions.
2. New Sudo Methods in Utilities Module: This commit introduces several new methods in the Utilities module to handle sudo operations securely. The `ask_for_sudo`, `test_sudo`, `deescalate_sudo`, and `use_sudo` methods have been created. These methods handle the secure acquisition, testing, de-escalation, and usage of sudo permissions, respectively. They ensure that sudo operations are performed securely and efficiently, with the sudo password being encrypted and cleared from memory immediately after use.
3. Improved Error Handling: The error handling within the `setup_traffic_mirroring` method has been refined. Now, when an exception is raised during the execution of a command, the error message is not only logged using the LoggMan logger but also an alert is enqueued into the AlertQueueManager. This dual approach ensures that errors are properly logged for debugging purposes and also communicated to the user in real-time.
4. AlertQueueManager Integration: The `initialize` method of NetworkingGenie has been updated to accept an `alert_queue_manager` parameter. This allows the NetworkingGenie class to enqueue alerts directly into the AlertQueueManager, thereby improving the communication of errors and important information to the user.
5. Dummy Interface Creation: The `create_dummy_interface` method now checks if the dummy interface already exists before attempting to create it. This prevents unnecessary system calls and potential errors.
These modifications significantly contribute to the overall security and reliability of the NETRAVE system. They ensure that network setup and traffic mirroring operations are performed securely and efficiently, with clear and immediate communication of any issues that may occur.
