Nessus is a tool that checks computers for vulnerabilities that hackers could exploit.

Step 1: Creating a Scan

Once you have installed and launched Nessus, you’re ready to start scanning. First, you have to create a scan. To create your scan:

In the top navigation bar, click Scans.
In the upper-right corner of the My Scans page, click the New Scan button.

Step 2: Choose a Scan Template

Next, click the scan template you want to use. Scan templates simplify the process by determining which settings are configurable and how they can be set.

Step 3: Configure Scan Settings

The Basic Network Scan template has several default settings preconfigured, which allows you to quickly perform your first scan and view results without a lot of effort.

Configure the settings in the Basic Settings section.
Configure remaining settings.

Although you can leave the remaining settings at their pre-configured default, Tenable recommends reviewing the Discovery, Assessment, Report, and Advanced settings to ensure they are appropriate for your environment.

Configure Credentials

Optionally, you can configure Credentials for a scan. This allows credentialed scans to run, which can provide much more complete results and a more thorough evaluation of the vulnerabilities in your environment.

Launch Scan

After you have configured all your settings, you can either click the Save button to launch the scan later or launch the scan immediately.

If you want to launch the scan immediately, click the button, and then click Launch. Launching the scan will also save it.

Step 4: Viewing Your Results

Viewing scan results can help you understand your organization’s security posture and vulnerabilities. Color-coded indicators and customizable viewing options allow you to tailor how you view your scan’s data.

You can view scan results in one of several views:

Viewing scan results by vulnerabilities gives you a view of potential risks on your assets.

0 view vulnerabilities:

2. Click the Vulnerabilities tab to view all vulnerabilities.
(Optional) To sort the vulnerabilities, click an attribute in the table header row to sort by that attribute.
Clicking on the vulnerability row will open the vulnerability details page, displaying plugin information and output for each instance on a host.

Step 5: Reporting Your Results

Chances are your job isn’t done yet. You need to report your findings to your team.
