What is the operating system (OS) fingerprinting? What are some purposes for OS fingerprinting?
Hi, I need to answer this question. The book name is "Hacker Techniques, Tools, and Incident Handling 3e". Thank you.
Question:
What is the
OPERATING SYSTEM FINGER PRINTING --
Determining the type of operating system used by studying the types of packets flowing from the system. Passive OS fingerprint scanning only analyzes packets. Active OS fingerprint sends challenges to the OS and evaluates the type of responses.
OS Fingerprinting is used by security experts and hackers to map remote networks and determine which threats are likely to be exploited.
It is a method used by cyber criminals and well-behaved hackers to determine the type of system used by a targeted computer on a network.
OS fingerprint printing only works on packages containing full TCP connections; that TCP connection must have SYN, SYN / ACK, and ACK connections.
PURPOSE OF OS FINGERPRINTING -
A fingerprint is a group of information that can be used to find software, network agreements, operating systems or hardware devices.
It is a popular method used to identify people involved in all kinds of crimes, from robbery to dispatch or even murder.
integrating data sets to detect - with high probability - network services, application number and version, software applications, info, configuration and more.
There Are Two Types Of Fingerprinting:
- Active
- Passive
Active Fingerprinting -
Active OS fingerprint scanning involves actively monitoring a targeted PC by sending carefully built-in packages to the targeted system and checking the TCP / IP behavior of the received responses.
An effective fingerprint scanner works by sending packets to the target and analyzing returned packets. Almost all active fingers these days are made with Nmap
Nmap uses a script that analyzes that data to print useful effects on OS fingerprint scanning. Performing OS scanning with finger on Nmap is easy.
