Port scanning software’s goal is to detect unauthorized services being run by users. It is also used to check for possible security risks that could threaten the server or workstation. 3. Nmap (Zenmap) is open source port scanning software that I would prefer. 4. As the software recommender for the company I would have to recommend Nmap to the Senior Administrator. Features of Nmap is that it is useful for performing tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, and what type of packet filters/firewalls are in use. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems. (nmap.org, 2014) Another reason I would recommend this software versus freeware software is the added security features built into it. nmap.org. (2014, April 5). nmap.org.
