Nessus is a powerful and easy-to-use remote security scanner that is not only free but also very fast to update. The function of the security scanner is to conduct a security check on the specified network to find out if there are any vulnerabilities in the network that are causing the opponent to attack. The system is designed as a client/sever mode, the server side is responsible for security checks, the client is used to configure the Management Server side. The server also employs a plug-in system that allows users to join plug-ins that perform specific functions, which allow for faster and more complex security checks. In Nessus, a shared information interface, known as the Knowledge Base, is used to save the results of previous checks. The results of the check can be saved in several formats, such as HTML, plain text, LaTeX (a text file format), and so on.

See Nessus released the latest version: 4.2.0, and my laptop installed or 4.0.2, so downloaded a, installed in the virtual machine to see.

I downloaded the version of Nessus 4.2.0 for Windows, widely used in Windows XP, 2003, Vista, 2008 & 7, with the bit and the bit can be used to download according to their own needs, I downloaded the bit.

Of course, you need to get a "activation Code", which is OK after clicking on the "main interface" in the image above.

To conduct a security assessment, you first need to develop a scan policy, and then add a scan range before you can scan, and the scan is complete to view the report. Is the use of several buttons mentioned above. Here we add the scanning strategy: Policies→add

Basically, just write "Name" and if you choose visibility as shared, others can use your strategy to scan. Fill in the "next" to see the following interface:
