There is a total of 65,535 TCP ports and another 65,565 UDP ports. All ports are potentially at risk of attack. The more commonly used a port is, the easier it can be to sneak attacks in with all the other packets. Attackers use TCP port 1080, which the industry has designated for socket secure SOCKS proxies, in support of malicious software and activity. Attacks on web clients that travel over port 80 include SQL injections, cross-site request forgeries, and buffer overruns.”]
