The NSE takes Nmap beyond the standard quick-and-dirty scans and into a deeper realm of automation, detail, and depth. Second, it enables Nmap users to author and share scripts, which provides a robust and ever-evolving library of preconfigured scans. First, it allows the nmap command to accept options that specify scripted procedures as part of a scan. What is the NSE? This tool does two things.

Remember the basic command line format for nmap is: Now let us take a look at the parameters NMAP uses to perform the different types of system scans.

The last thing to remember is that these scans can only be ran one at a time except if you are running a UDP and TCP scan at the same time. Of the scan types listed below table, only the connect and ftp bounce scans can be ran without privileged access. This is required because the scans send raw packets which require privileged system access. One very important aspect of NMAP to remember is that these scans should be ran with Root or Administrator access depending on the type of system you are using. But as with all powerful tools, Nmap can be used for far more than breaking into networks.

Normally, when people think of Nmap, they assume it’s used to conduct some sort of nefarious network reconnaissance in preparation for an attack. Nmap is a free tool that can be used to conduct various sorts of scans on networks.
