Portspoof: Open-Source Port Spoofing Tool Thwarts Port Scans

Portspoof is an open-source port spoofing tool designed to enhance OS security. It confuses port scanners by always keeping all 65535 TCP ports open and responding with SYN+ACK to every connection attempt. Furthermore, Portspoof boasts a massive database of dynamic service signatures, mimicking various service banners to further hinder attackers from identifying real services. This significantly increases the time and difficulty for attackers to perform port scans and service identification, effectively improving system security without requiring root privileges.
