Using a web port scanner to map and secure your network

A web port scanner allows one to scan an IP or a host for an open or closed transmission control program (TCP) port. It’s commonly used by administrators who need to verify the security and mapping of their networks. The main role of a web port scanner is to connect the administrator on specific ports and IP addresses.

Before you decide to use a port scanner, you must first decide on the range of the network. Secondly, you need to configure the scanner to the depth you wish to scan the IP addresses on a network. Always remember, every time you connect to the network, the security of your network is put to test.

How a web port scanner works

The scanner helps one to identify the number of holes that can be used by an attacker. Since hackers look on how to access and damage your resources, you should not leave any holes unplugged. The scanner will probe a server or a host. It uses raw IP packets that help to identify the services running on a host. In addition, it checks if the server is firewall enabled, which ports are open and which operating system is running. The scanner also tests the security web applications that are running.

How to launch a web port scanner

· Enter the host name

You should enter a host name or valid target addresses that can be accessed from an external perspective.

· Identify the ports you wish to scan

It’s advisable that you scan all ports for a full test of a firewall configuration. This can take 30 minutes or more depending on the network.

· Launch the web port scanner

When the scan is completed, results are sent to the registered email address.

New security threats are coming up every day. It’s recommended that before you launch any scan on a website hosted on a server, you first check with the hosting provider.
