Tenable One 2024 Release Notes

Tenable Inventory now includes an Attack Path column on the Assets and Weaknesses pages, as well as a Choke Point column on the Assets page. Users can click on the data within these columns to navigate directly to Attack Path Analysis to dive deeper into the relevant attack path information.

For more information, see Assets and Weaknesses in the Tenable Inventory User Guide.

Users can now input a CIDR range for the IPv4 address property. This allows you to efficiently filter assets and simplifies querying by reducing the complexity of managing IP-based filters.

For more information, see Global Asset Search in the Tenable Inventory User Guide.

Cloud labels can now be used to filter, search, and create tags by using the new External Tags property. This provides improved context by adding more detailed information to the Assets page. Additionally, this improves advanced reporting by enabling the creation of custom exposure cards using cloud labels for tailored reporting needs.

For more information, see Assets in the Tenable Inventory User Guide.

• Attack Path Analysis added additional support for fixed Findings:

  • All findings that are resolved will be marked as Done and Archived.

  • All findings that are no longer part of an attack path will be marked as Archived within the relevant activity log.

• Attack Path Analysis now includes an application navigator that allows users to search the entire application. When you select a search result, you automatically navigate to that page within Attack Path Analysis. You can look for pages in the application, queries in the query library, MITRE ATT&CK Heatmap categories, and more.

• Added an AI Assistant button in the canvas interaction panel.

Attack Path Analysis reduced the data pipeline execution time by 25%. Additionally, Attack Path Analysis will only process licensed assets in order to optimize COGS and reduce data processing time.

In the MITRE ATT&CK section, Attack Path Analysis now includes support for the Msiexec technique.

The Attack Path Analysis Discover section now includes an AI assistant for Asset Node and Attack Path explainability.

• The MITRE Att&ck page now includes support for the Remote Access Software technique.

The Tenable One Exposure team is excited to announce that we have released an initial version of the new category card for OT in Lumin Exposure View. You can view the new OT Exposure Card under the Exposure Card Library > Category section. This card includes the Overall Score, Trend, and Tag Performance metrics. You can also drill down from Lumin Exposure View into Cyber Asset Management to see your OT assets. To easily filter OT assets within Inventory, we introduce quick filters to find all your OT assets quickly.

Attack Path Analysis now supports the following Ransomware Queries within the Query Library:

• LPHV Blackat

• CL0P

• LockBit

• 8base

• Akira

Beginning in this release, users can see which users created/updated a bookmark within the Attack Path Analysis Query Library.

• In the MITRE ATT&CK section, we have extended External Remote Services technique support for SSH and VNC protocols.

• On all Discover/Findings pages, all additional information now appears in the side details panel.

• On the Discover page, we removed the Tactics List in the canvas bracket to avoid flooding the screen with text.

Beginning in this release, the definition of the Path Priority Rating has changed:

• Path Priority Rating (new metric) - prioritization metric for attack paths based on the exposure of the source, criticality of the target and the number of steps of the attack path.

• Choke Point Priority (previously known as Path Priority Rating) - prioritization metric for attack techniques based on the number of attack paths exploiting the attack, the number of critical assets it leads to, and the complexity of the attack.

The new Discover landing page will now show the top attack paths by default. Additionally, you can now perform a search for asset nodes separately from attack paths by using the Asset Query Builder.

Attack Path Analysis now includes the following generative AI capabilities:

• Attack Path Summarization - transforms the graphical representation of an attack path to natural language including title and executive summary. This enables our users to better understand the impact of attack paths and improve their ability to communicate it with the relevant stakeholders.

• Mitigation Guidelines - The Findings Details page now includes the ability to get more practical mitigation guidelines. This improves the efficiency of users asking to act on findings and eliminate attack paths.

The attack path table is now the first step when searching attack paths. Each attack path has a title and summary. Each path has a new metric of Path Priority Rating, so users can better visualize the attack path.

When a user views an attack path, they can now drill down to the choke points (findings) that were found as part of the attack path.
