In today’s world, network security needs no introduction or explanation. We all know that the term network security means securing any computer network so that nobody accesses, manipulates or malfunctions the network in any way. Therefore, we have rules, policies and instructions concerning computer network monitoring and security.

Network scanning is integral to the maintenance and security of the network and refers to a process of detecting and identifying network vulnerabilities and failures in order to prevent others from unauthorized access to or monitoring of a network. There are currently a number of network vulnerability scanning tools, some free and some paid, on the market. These features are diverse.
