Download Nessus and Nessus Manager. There may be scenarios where a Tenable. There are several ways to do this that require no additional logging be enabled. Nessus is a remote security scanning tool, which scans a computer and raises an alert if it discovers any vulnerabilities that malicious hackers could use to gain access to any computer you have connected to a network. It does this by running over checks on a given computer, testing to see if any of these attacks could be used to break into the computer or otherwise harm it.
If you are an administrator in charge of any computer or group of computers connected to the internet, Nessus is a great tool help keep their domains free of the easy vulnerabilities that hackers and viruses commonly look to exploit. Nessus is not a complete security solution, rather it is one small part of a good security strategy. Nessus does not actively prevent attacks, it is only a tool that checks your computers to find vulnerabilities that hackers COULD exploit.
If you are familiar with other network vulnerability scanners, you might be wondering what advantages Nessus has over them. Key points include:. Its also provides a plug-in interface, and many free plug-ins are available from theNessus plug-in site.
These plugs are often specific to detecting a common virus or vulnerability. The Nessus team updates the list of what vulnerabilities to check for on a daily basis in order to minimize the window between an exploit appearing in the wild, and you being able to detect it with Nessus. Nessus is open source, meaning it costs nothing, and you are free to see and modify the source as you wish. To learn how Nessus and other port-scanning security tools work, it is necessary to understand different services such as a web server, SMTP server, FTP server, etc are accessed on a remote server.
Most high-level network traffic, such as email, web pages, etc reach a server via a high-level protocol that is transmitted reliably by a TCP stream. To keep different streams from interfering with each other, a computer divides its physical connection to the network into thousands of logical paths, called ports. So if you want to talk to a web server on a given machine, you would connect to port 80 the standard HTTP port , but if you wanted to connect to an SMTP server on that same machine you would instead connect to port Each computer has thousands of ports, all of which may or may not have services ie: a server for a specific high-level protocol listening on them.
Nessus works by testing each port on a computer, determining what service it is running, and then testing this service to make sure there are no vulnerabilities in it that could be used by a hacker to carry out a malicious attack. Nessus is called a ‘remote scanner’ because it does not need to be installed on a computer for it to test that computer. Instead, you can install it on only one computer and test as many computers as you would like. Nessus comes in two parts, a server called nessusd and a client, which can by any of several options.
The server is the part of Nessus that actually runs the tests, and the client is used to tell the server what tests to run on what computers. Therefore, once the server is set up and running, an administrator can run regularly scheduled Nessus tests using a client written for almost any platform. Go to www. This will install the Nessus server app and a client on the unix based machine note: this includes Mac OS X and above with developer tools installed.
To run a scan, you must have the Nessus server running on some machine, then start up a Nessus client. The client will look something like this:. The two most important tabs are ‘Nessusd host’, which allows you to enter in the IP address of the Nessus server you will connect to, as well as the username and password needed to connect to this server.
The other critical tab is labeled ‘Target Selection’. This is where you specify which host s you would like to scan. After a scan, Nessus clients typically offer to means to analyze the result. The client itself will often list each vulnerability found, gauging its level of severity and suggesting to the user how this problem could be fixed. An example screen is shown below:. Nessus clients are also able to generate more comprehensive and graphical reports in a variety of different formats.
The main Nessus website is www. Nessus scans cover a wide range of technologies including operating systems, network devices, hypervisors, databases, web servers, and critical infrastructure. The results can also be saved in a knowledge base for debugging. On UNIX, scanning can be automated through the use of a command-line client. There exist many different commercial, free and open source tools for both UNIX and Windows to manage individual or distributed Nessus scanners.
Nessus provides additional functionality beyond testing for known network vulnerabilities. For instance, it can use Windows credentials to examine patch levels on computers running the Windows operating system. The Nessus Project was started by Renaud Deraison in to provide to the Internet community with a free remote security scanner. Today, the product still exists in two formats; a limited, free version and a full-feature paid subscription option.
