Tenable Vulnerability Management

Deploy Tenable Vulnerability Management

Deploy Tenable Vulnerability Management according to the steps outlined in the Tenable Vulnerability Management User Guide, or based on guidelines received directly from Tenable Professional Services.

Configure Tenable Vulnerability Management for Use in Tenable One

Once you have installed Tenable Vulnerability Management, consider the following best practices for configuring the product for use:

Tags

• Tags you create in Tenable Vulnerability Management are crucial in Tenable Exposure Management. These tags help you visualize your assets within the Lumin Exposure View. For example, you can separate your tags by tier, business unit, physical location, etc.

• Keep in mind: how you tag your assets in Tenable Vulnerability Management dictates how that asset data appears in Tenable One. In Tenable Exposure Management, you can create custom exposure cards to assess the exposure of those assets.

• Any tags you create in Tenable Vulnerability Management automatically sync in Tenable Exposure Management. You can view them on the Assets page.

  Tip: You can also create tags directly in Tenable One.

• When you bring more data (for example, from Tenable Web App Scanning and Tenable Cloud Security) into Tenable One, you can tag assets from multiple data sources within a single tag.

Scanning

• When considering how data makes its way from Tenable Vulnerability Management into Attack Path Analysis, remember: the more (authenticated) data, the better! When you configure remote Tenable Vulnerability Management scans, be sure to enable the Override Normal Verbosity report setting. This ensures the Attack Path Analysis has the most data possible to work with when generating attack paths for your environment.

• The more you scan, the more often your data refreshes in Tenable One. The more frequently your data refreshes, the more relevant the data being presented. If you only scan once a month, be aware that by the end of the month, your data will likely be out of date.

• Review the Asset Criticality Rating of your most critical assets. Most organizations know about their critical assets (ACR = 10). From there, work backwards to identify the next most important assets and validate/adjust their ACR as necessary.

  Note: By default, Tenable will not assign an asset an ACR above an 8. You must manually edit an asset's ACR to set it to a 9 or 10.

Onboarding Milestones

Tenable suggests you complete the following milestones to ensure your success before proceeding with your Tenable One deployment process:

• Access the Exposure View page, where you can gain critical business context by getting business-aligned cyber exposure score for critical business services, processes and functions, and track delivery against SLAs. Track overall VM risk to understand the risk contribution of assets to your overall Cyber Exposure Score, including by asset class, vendor, or by tags.

  • View and manage cyber exposure cards.

  • View CES and CES trend data for the Global and Vulnerability Management exposure cards.

  • View Remediation Service Level Agreement (SLA) data.

  • View Tag Performance data.

• Access the Exposure Signals page, where you can generate exposure signals that use queries to search for asset violations. Simply put, if an asset is impacted by a weakness related to the query, then the asset is considered a violation. Using this, you can gain visibility into your most critical risk scenarios.

  • Find top active threats in your environment with up-to-date feeds from Tenable Research.

  • View, generate, and interact with the data from queries and their impacted asset violations.

  • Create custom exposure signals to view business-specific risks and weaknesses

• Access the Inventory page, where you can enhance asset intelligence by accessing deeper asset insights, including related attack paths, tags, exposure cards, users, relationships, and more. Improve risk scoring by gaining a more complete view of asset exposure, with an asset exposure score that assesses total asset risk and asset criticality.

  • View and interact with the data on the Assets tab:

    • Review your AD assets to understand the strategic nature of the interface. This should help set your expectations on what features to use within Tenable Exposure Management, and when.

    • Familiarize yourself with the Global Asset Search and its objects and properties. Bookmark custom queries for later use.

    • Find devices, user accounts, software, cloud assets, SaaS applications, networks, and their weaknesses.

    • Drill down into the Asset Details page to view asset properties and all associated context views.

  • View and interact with the data on the Weaknesses tab:

    • View key context on vulnerability and misconfiguration weaknesses to make the most impactful remediation decisions.

  • View and interact with the data on the Software tab:

    • Gain full visibility of the software deployed across your business and better understand the associated risks.

    • Identify what software may be out of date, and which pieces of software may soon be End of Life (EoL).

  • View and interact with the data on the Findings tab:

    • View instances of weaknesses (vulnerabilities or misconfigurations) appearing on an asset, identified uniquely by plugin ID, port, and protocol.

    • Review insights into those findings, including descriptions, assets affected, criticality, and more to identify potential security risks, visibility on under-utilized resources, and support compliance efforts.

• Access the Attack Path page, where you can optimize risk prioritization by exposing risky attack paths that traverse the attack surface, including web apps, IT, OT, IoT, identities, ASM, and prevent material impact. Streamline mitigation by identifying choke points to disrupt attack paths with mitigation guidance, and gain deep expertise with AI insights (Not supported in FedRAMP environments).

  • View the Dashboard tab for a high-level view of your vulnerable assets such as the number of attack paths leading to these critical assets, the number of open attack techniques and their severity, a matrix to view paths with different source node exposure score and ACR target value combinations, and a list of trending attack paths.

    • Review the Top Attack Path Matrix and click the Top Attack Paths tile to view more information about paths leading to your “Crown Jewels”, or assets with an ACR of 7 or above.

    You can adjust these if needed to ensure you’re viewing the most critical attack path data.

  • On the Top Attack Techniques tab, view all attack techniques that exist in one or more attack paths that lead to one or more critical assets by pairing your data with advanced graph analytics and the MITRE ATT&CK® Framework to create attack techniques, which allow you to understand and act on the unknowns that enable and amplify threat impact on your assets and information.

  • On the Top Attack Paths tab, generate attack path queries to view your assets as part of potential attack paths:

    • Generate an Attack Path with a Built-in Query

    • Generate an Attack Path Query with the Attack Path Query Builder

    • Generate an Asset Query with the Asset Query Builder

    Then, you can view and interact with the Attack Path Query and Asset Query data via the query result list and the interactive graph.

  • Interact with the MITRE ATT&CK Heatmap tab.

• View and interact with the data in the Tags page:

  • Create and manage tags to highlight or combine different asset classes.

  • View the Tag Details page to gain further insight into the tags associated with your assets.
