The school that my son goes to blocks outbound SSH traffic. The users inside the network can't use Port 22 / trying to make a SSH connection through another port is also blocked. The reason I was given for this was because it's putting the users inside the network at risk and would allow port forwarding.
I'm not seeing how allowing my son and other students to make outbound connections really improves security that much. What security implications are there for allowing outbound SSH traffic?
