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.
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. For a detailed explanation of all the options available, refer to Scan and Policy Settings in the Nessus User Guide.
A scan policy is a set of predefined configuration options related to performing a scan. After you create a policy, you can select it as a template in the User Defined tab when you create a scan. For more information, see Create a Policy in the Nessus User Guide.
The Nessus interface provides brief explanations of each template in the product. Some templates are only available when you purchase a fully licensed copy of Nessus Professional.
To see a full list of the types of templates available in Nessus, see Scan and Policy Templates. To quickly get started with Nessus, use the Basic Network Scan template.
Step 3: Configure Scan SettingsPrepare your scan by configuring the settings available for your chosen template. 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.
Follow these steps to run a basic scan:
1. Configure the settings in the Basic Settings section.
The following are Basic settings:
SettingDescriptionNameSpecifies the name of the scan or policy. This value is displayed on the Nessus interface.Description(Optional) Specifies a description of the scan or policy.FolderSpecifies the thư mục where the scan appears after being saved.TargetsSpecifies one or more targets to be scanned. If you select a target group or upload a targets file, you are not required to specify additional targets.2. Configure remaining settingsAlthough you can leave the remaining settings their pre-configured default, Tenable recommends reviewing the Discovery, Assessment, Report and Advanced settings to ensure they are appropriate for your environment.
For more information, see the Scan Settings documentation in the Nessus User Guide.
3. Configure CredentialsOptionally, 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.
4. Launch ScanAfter 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 thebutton, and then click Launch. Launching the scan will also save it.
The time it takes to complete a scan involves many factors, such as network speed and congestion, so the scan may take some time to run.
Step 4: Viewing Your ResultsViewing 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:
PageDescriptionHostsDisplays all scanned targets.VulnerabilitiesList of identified vulnerabilities, sorted by severity.RemediationsIf the scan's results include remediation information, this list displays all remediation details, sorted by the number of vulnerabilities.NotesDisplays additional information about the scan and the scan’s results.HistoryDisplays a list of scans: Start Time, End Time, and the Scan Statuses.Viewing scan results by vulnerabilities gives you a view into potential risks on your assets.
To view vulnerabilities:
In the top navigation bar, click Scans.Click the scan for which you want to view results.Do one of the following:- Click a specific host to view vulnerabilities found on that host.Click the Vulnerabilities tab to view all vulnerabilities.
Step 5: Reporting Your ResultsChances are your job isn’t done yet. You need to report your findings to your team.
Scan results can be exported in several file formats. Some of these report formats are customizable, while others are designed to be imported into another application or product, such as Microsoft Excel or Tenable.sc. For an explanation of the various report formats and the purpose of each, see the Nessus User Guide.
To Export a Scan Report:
Start from a scan's results pageIn the upper-right corner, click Export.From the drop-down box, select the format in which you want to export the scan results.Click Export to tải về the report.Thanks for using Nessus! Once your first scan is complete, you can begin to discover more of what Nessus has to offer. If you have additional questions, please see the Nessus FAQs or join in the conversation on the Tenable Community.
What's the first step that vulnerability scanners perform during scanning a network?
1. Perform the Initial Scan This gives you a baseline of issues and is used in subsequent steps. 2. Verify the Scan Results Some of the issues a vulnerability scanner finds may be false positives.What can we determine by scanning for vulnerabilities with a vulnerability scanner?
A vulnerability scan only identifies vulnerabilities, while a penetration tester digs deeper to identify the root cause of the vulnerability that allows access to secure systems or stored sensitive data. The pen tester also looks for business logic vulnerabilities that might be missed by an automatic scanner.What is network vulnerability scanning?
Network vulnerability scanning is the process of identifying weaknesses on a computer, network, or other IT asset that are potential targets for exploitation by threat actors.How is vulnerability scanning done?
The vulnerability scanner uses a database to compare details about the target attack surface. The database references known flaws, coding bugs, packet construction anomalies, default configurations, and potential paths to sensitive data that can be exploited by attackers.
