Nmap and 12 useful NSE scripts.

Nmap is the most popular free security scanner developed by Gordon Lyon (f.f. Fyodor Vaskovich). The first version of Nmapa was published on October 1, 1997, in the online magazine, Phrack.

For those interested in the beginnings of this scanner, here is a full article that shows the capabilities and source code of the first version of Nmap: The Art of Port Scanning.

At the time of writing this text, the latest version of Nmap is 7.70. This version is equipped with 588 NSM scripts (Nmap Scripting Engine), which, along with a huge number of standard scanning options, give the opportunity to examine more carefully the hosts we are interested in.

NSE can be used, among others, to more accurately detect the version of a given service, break usernames and passwords, detect and use known vulnerabilities, and even detect existing back gates left by the attacker and fuzzing.

A list of all available scripts with descriptions is published at https://nmap.org/nsedoc/. Alternatively, to get a list, we can use the terminal (assuming that Nmap has been installed in the default location): read more....

Although this is flexible, this creates many unnecessary problems. In particular, this lack of limitations makes it unnecessarily difficult to write correct programs (enabling many security flaws), makes it impossible to consistently and accurately display filenames, causes portability problems, and confuses users. more ....
