15 Best Network Scanning Tools (Network and IP Scanner) Of 2020

Best Network Scanning Tools (Top Network and IP Scanner) For Top-Notch Network Security:

The network is a vast term in the world of technology. The network is known as the backbone of the telecommunication system which is used to share data and resources using data link.

The next term that comes into the frame is Network Security. Network Security consists of a set of rules, policies, and instructions that are accepted to monitor and prevent the misuse and unauthorized manipulation of a network.

Network scanning deals with Network Security and this is an activity that identifies network vulnerabilities and the loopholes to safeguard your network from unwanted and unusual behavior that can harm your system. It can harm even your personal and confidential information.

Most Useful Network Scanning Tools

This article will brief you about the most popular Network Scanning Tools that are available in the market along with their official links and key features for your easy understanding.

What Is Network Scanning?

Network Scanning is a process that can be defined in many ways, it identifies the active hosts (Clients and servers) on a network and their activities to attack a network. It is also being used by attackers to hack the system.

This procedure is used for system maintenance and security assessment of a network.

In short, Network Scanning process includes:

  • Identifying filtering systems between two active hosts on a network.
  • Running UDP and TCP network services.
  • Detect TCP Sequence Number of both the hosts.

Network Scanning also refers to Port Scanning in which the data packets are sent to a specified port number.
