A port scanner is a software application designed to probe a server or host for open ports. This is

often used by administrators to verify security policies of their networks and by attackers to

identify running services on a host with the view to compromise it. The main purpose of port

scanning is to find out as much information as you can on the target in order to see if there are

any known vulnerabilities - correct?? For instance, in the example below. I learn that

PCAnywhere data uses port 5631 to communicate. So my goal would be to look for known

exploits with PC Anywhere.

Is this the main purpose of port scanning? Open source.   It’s actually easier to deal with a bug

fix for open source than it is for proprietary software. In open source, bugs are typically

submitted to an online issue tracking system, which is public to any user. For simple everyday

support issues there really isn’t much difference between open source support and proprietary

software support. Nap ("Network Mapper") is a free and open source utility for network

discovery and security auditing.

Many systems and network administrators also find it useful for 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 those

hosts are offering, what operating systems they are running, what type of packet filters/firewalls

are in use, and dozens of other characteristics. It was designed to rapidly scan large networks,

and also works against. That was my essay hope you enjoyed.
