Port Knocker: An Handy Tool for Secure Network Access

Understanding Port Knocking

Port knocking is a method used to dynamically open ports on a firewall by generating a connection attempt on a set of predefined closed ports. When these specific attempts are observed in the correct sequence, the firewall rules are adjusted to allow the host that sent the sequence to connect through the firewall.
