A backdoor can be created in a router by the manufacturer to remote access on the device. It could be for the purpose of troubleshooting but sometimes it could be used with a malicious intent to compromise security or sniff network data of an organisation. Security of network router is of utmost importance to secure the assets within an enterprise. Design a solution to detect backdoors in them.
Notes: Simulate a back doored router to demonstrate the solution. For simulation purpose, use a router with known back doored firmware or modify publicly available firmware to create a backdoor and use it in a router for POC purpose.
Sample Data Required: No
