In the network security world, nmap is the king for fingerprinting systems and services over the network. It can help identify the operating system (OS), type, and version of a network service, and vulnerabilities that might be present. . The problem with nmap is that it generates a lot of "noise" when it performs those activities because it has to send out packets to the system in question to learn more about it. Nmap is an example of an active fingerprinting tool. There are less noisy alternatives to nmap that fall into the passive fingerprinting category. Instead of actively sending packets to a host and service, they passively analyze network traffic to identify unique characteristics for particular operating systems, client applications, and network services. Their strength is based on the breadth of their signature database, which is not always great. To date, the majority of free and open-source passive fingerprinting tools have focused on OS fingerprinting The link for this article located at Dark Reading is no longer available. . p0f offers an innovative approach to passive network fingerprinting by utilizing advanced techniques that improve system identification while minimizing irrelevant data..

Most of todays tools for fingerprinting are focusing on server-side services. Well-known and widely-accepted implementations of such utilities are available for http web services, smtp mail server, ftp servers and even telnet daemons. Of course, many attack scenarios are focusing on server-side attacks. This implementation of client-side fingerprinting utilizes PHP to identify browsers by http requests. See how this application fares against other fingerprinting utilities that analyze header lines and values.. The link for this article located at Darknet.org is no longer available. .

"One of the challenges of network security is learning about the bad guys. To understand your threats and better protect against them, you have to Know Your Enemy. Passive Fingerprinting is a method to learn more about the enemy, without them knowing it. Specifically, you can determine the operating system and other characteristics of the remote host using nothing more then sniffer traces. Though not 100% accurate, you can get surprisingly good results." The link for this article located at RootPrompt.org [LinuxToday] is no longer available. .
