knock_knock

Inspiration

Having services available to the Internet opens the possibility for brute forcing of logins. Lots of these attempts happen all the time. If your SSH is closed to the world until a series of port knocks happen, it reduces the chance of these attacks. STRATFOR is a real world example of attackers farming possible logins from social media and then brute forcing their way.

What it does

Prevent unauthorized users from attempting to connect to a service and brute force it

How we built it

Using Python, we used the scapy library to send pings to ports 1000,2000 adn 3000 which turned on the SSH on a unusual port and sent it as a response
