Get Started with Tenable Identity Exposure 3.77 On-Premises

Use the following workflow to perform your deployment of Tenable Identity Exposure 3.77.

Check Prerequisites

1. Review the Release Notes.

2. Select your On-Premises Architectures — Tenable Identity Exposure offers two deployment options depending on your specific needs.

3. Check Pre-deployment Requirements — For optimal performance, Tenable Identity Exposure requires careful resource planning. This entails analyzing your Active Directory environment, specifically the total number of objects, to determine the necessary memory and processing power.

   Caution: Starting with Tenable Identity Exposure version 3.59.5, ensure that your TLS certificates use OpenSSL 3.0.x.

Install

1. Select your deployment:

   • Install Tenable Identity Exposure.

   • Upgrade Tenable Identity Exposure.

     Tip: If you are upgrading from v. 3.42 to 3.77, be sure you review the sections Secure Relay Requirements and Secure Relay Architectures for On-Premises Platforms.

2. Install the Secure Relay for Tenable Identity Exposure 3.77.

Configure

1. Post-deployment — Restart Services, Logs for Troubleshooting, Post-deployment Tasks.

2. Review Tenable Identity ExposureTenable Identity Exposure Licensing.

Expand Tenable Identity Exposure into Tenable One

Integrate OT Security with Tenable One and leverage the following features:

• In Lumin Exposure View, 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 identity risk to understand the risk contribution of web applications to your overall cyber exposure score.

  • Review the Global exposure card to understand your holistic score. Click Per Exposure to understand what factors are driving your score, and by how much.

  • Review the Active Directoryexposure card.

  • Configure the exposure view settings to set a customized Card Target and configure Remediation SLA and SLA Efficiency based on your company policy.

  • Create a custom exposure card based on business context (for example, Domains, Domain Admins, Asset Criticality, Critical Users/Critical Assets, or Service Accounts).

• In Tenable Inventory, 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 for identities.

  • 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 Inventory, and when.

  • Review the Tenable Queries that you can use, edit, and bookmark.

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

    Tip: To get a quick view of what properties are available:

    • In the query builder, type has. A list of suggested asset properties appears.
    • Customize the list by adding a column. A list of available columns/properties appears.
  • Drill down into the asset details page to view asset properties and all associated context views.

  • (Optional) Create a tag that combines different asset classes.

• In Attack Path Analysis, 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.

  • View the Attack Path Analysis Dashboard 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 findings 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 Domain Admins.

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

  • On the Findings page, 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 Findings, which allow you to understand and act on the unknowns that enable and amplify threat impact on your assets and information.

  • On the Discover page, generate attack path queries to view your assets as part of potential attack paths:

    • Generate an Attack Path using a Built-in Query

    • Generate an Asset Query using the Asset Query Builder

    • Generate an Attack Path Query using the Attack Path 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.
