Network testing tools

System admins can use many different tools to scan and probe their networks, looking for security vulnerabilities.

One of the simplest pieces of software is a port scanner – this checks all IP addresses within a supplied range, and scans all ports to see whether any of the machines are listening on those ports.

Port scanners can reveal what devices are connected to a network, and also what software services are running on those devices. This can be an important first step when trying to attack a network; it is therefore also an important step in securing a network.

There are also network management packages, for example KaliOS – this provides tools to inspect a network, discover devices and software, probe devices to see if they are patched or vulnerable to attack, and much more.
