Enhance SSH Security with Port Knocking #28

Open Jsitech opened 5 years ago

Port Knocking can be used to further secure the SSH Server. Adding port knocking will set a Firewall rule to block SSH access from everywhere. To access, a sequence of connections attempts to predefined ports must be made to enable access to SSH.
