The main intent of developing this toolkit was to provide the network security administrator with a comprehensive set of open source network security tools. The majority of tools published in the article: Top 100 Security Tools by insecure.org are available in the toolkit.
What we find rather fascinating with NST is that we can transform an ordinary system into a system designed for network traffic analysis, intrusion detection, network packet generation, wireless network monitoring, a virtual system service server, or a sophisticated network/host scanner. This can all be done without disturbing or modifying any underlying sub-system disk. NST can be up and running on a typical system in less than a minute. The hard disk will not be altered in any way.
NST also makes an excellent tool to help one with all sorts of crash recovery troubleshooting scenarios and situations.
