Anyone who has used Linux long enough will look at numbers such as 22 and 80 in a totally different light than everyone else. Default port numbers are expected to be hammered with tons of packets day to day, from legitimate user requests to probes sent by nmap scans. Changing services such as SSH and FTP to non-default numbers are not only a tactic for securing your server - they're a tactic for malicious users to hide these services as backdoors once a system is compromised. Read on to see how scanning tools such as Passive Vulnerability Scanner and Nessus can be used to scan for these "off port" services. . If you are attempting to perform network security monitoring in a large, unmanaged environment that has "poor" security, you are most likely dealing with botnets, phishing attempts, worms and Trojans. Many of these threats install some sort of FTP, SSH or Web server as a backdoor or drop point on a port other than the typical default port. Discovering these on your network may help you find compromised servers, or even administrators who are trying to bypass firewall rules. This blog entry discusses how to find these "off port" services with the Passive Vulnerability Scanner (PVS), Nessus scanner and through log analysis.

Port scanning is an important tool to detect what services your computer is running.

Port scanning is an important tool to detect what services your computer is running. Although they are getting better, many default Linux installs still leave many unnecessary services on, which can open your machine to security compromises. A sure way to see what you have running is to port scan your own system (IE localhost). Port scanning is also a good technique to test firewall rule sets. Port scanning is an important initial step towards knowing yourself. If you don't know what services you have running, it will be impossible to secure them from malicious crackers. It is also important to familiarize yourself with port scanning programs so you will know your "enemy", system crackers, who will often employ a port scan to determine if you have an exploitable service running. Advanced port scan tools will even do TCP/IP stack fingerprinting, allowing an attacker to determine what operating system you are running, often down to the kernel version!
