As a result of my interest in Information Security, I have been using Nmap in some capacity for several years and have followed each release of the tool with perhaps more than a little interest. That having been said, I am pleased to note that Nmap version 5.0 has just been released! The Nmap 5.0 release is noted as the most important release since 1997, according to the nmap website.
Out of the over 600 significant changes for the new release, the top five features according to the authors in the new release include the following:
The new Ncat tool will be your tool of choice for data transfer, redirection, and debugging. Details are available here: http://nmap.org/5/#changes-ncat
The addition of the Ndiff scan comparison tool enables users the ability to note changes that occur on the network to include new systems or services running on your network for example. Details are available here: http://nmap.org/5/#changes-ndiff
Nmap performance has improved dramatically thanks to the ability to utilize existing data and improved congestion control algorithms. Details are available here: http://nmap.org/5/#changes-performance
The official Nmap guide to network discovery and security scanning, “Nmap Network Scanning” has been released. More than half the book is available in the online edition located here http://nmap.org/book/toc.html. Additional details are available here: http://nmap.org/5/#changes-book
- The Nmap Scripting Engine (NSE) allows users to write scripts to automate a wide variety of networking tasks. All NSE scripts and modules are described in the new NSE documentation portal. Details are available here: http://nmap.org/5/#changes-nse
So when you have a moment, download the new Nmap 5.0 and enjoy some happy hacking with the latest and greatest features it has to offer.
