What You Need To Know About Port Scanner Windows

A port scanner windows is a computer application that is used to find ports that are vulnerable in a network server. The port scanner is used by two categories of people.

The first category is made up of the administrators who use it to verify the security policies of their network.

The second category is made up of the attackers who use it in identifying network servers that are running on a host. They also use it to exploit vulnerabilities.

Port scanning is sometimes seen as a nefarious act by some individuals due to the process it involves.

So as long as your computer is connected to a network, whether local area network or even the internet, an attacker with the help of a port scanner can have access to different information from a target system.

The kind of information port scanners receives include the type of services being run on a system, the owner of the services running, anonymous login supports (if any) and also the number of network services that need authentication.

A Port Scanner Windows:

When the scanning is on-going, the level of immediate feedback gotten will be interpreted to reveal weakness or strength of a network’s firewall, and if this gets into the hands of an attacker, they could probe further for more weaknesses and ultimately gain access to the information listed above.

The internet is operated and designed based on the Internet Protocol Suite also known as the TCP/IP (Transmission Control Protocol).

This system’s network services are referenced making use of two components; the port number and the host address and there are 65536 discrete and functioning port numbers.

Port scans have been programmed by popular port scanning tools like Nessus And Nmap and here are some you should know.

1. Address Resolution Protocol (ARP):

This port scanner discovers active devices on a local area segment by sending a swift series of ARP broadcasts as well as incrementing the worth (value) for that target IP address field in every broadcast packet.

The Address Resolution Protocol will have each IP device on the network respond with its IP address in response. It will efficiently map out an entire network.

This will give you a complete idea of everything you need to know about keeping your system safe from vulnerabilities.

2. The Vanilla connect scan:

(TCP) is the simplest port scanning technique that can be used to probe a network server. This form of scanning establishes a full TCP/IP connection with the first TCP port of the target machine and then continues the process through the other ports incrementally.

The TCP scanners are the simplest forms of scanners, and they use the operating system’s network functions. The first 1024 TCP ports are associated with standard services like the HTTP, SMTP
