(Early Access) Tenable OT Security 3.19 (2024-07-08)

Note: This version of Tenable OT Security is an Early Access release. To opt in to Early Access, contact your Tenable representative.

Vendor and Protocol Support

  • MOXA Discovery Protocol — OT Security now actively detects and fingerprints MOXA devices. Query the device directly to identify it. Active queries to MOXA devices require MOXA credentials.

  • Siemens SICAM 8050 RTU — OT Security now supports Siemens SICAM 8050. You can use active queries to fingerprint backplane modules, which require an SNMP v3 credential.

  • Fox-TLS Protocol

    • OT Security now actively detects and fingerprints devices that use the FOX-TLS protocol.

    • Active queries to these devices require FOX-TLS credentials.

    • Tested on Phoenix Contact ILC 2050 BI device.

IoT Connectors Engine

  • OT Security now includes an IoT Connectors engine that allows you to integrate your IoT (Internet of Things) or VMS (Video Management System) servers.

  • You can integrate your IoT/VMS servers using any one of the following connection methods:

    • Using a remote application API service

    • Using an agent

  • After integration, OT Security imports all the devices that the application server manages, such as cameras, badge access systems, fire panels, and so on.

    For more information, see IoT Connectors.

Asset Relationships

  • OT Security now provides a visual representation of asset relationships.

  • You can use the Related Assets tab on the single asset page to track all known relationships of the asset.

  • OT Security determines the relationship between assets automatically based on queries and passive monitoring. This prevents you from modifying these relationships manually.

  • Related Assets is based on actual communication pathways to devices, which distinguishes it from Network Map that relies on Layer 3 (Internet Protocol or IP) connectivity.

Asset Relationships - Nested OT Devices

  • Nested devices are Programmable Logic Controller (PLC)s or other Industrial Control System (ICS) modules connected behind a PLC backplane or device. This is similar to a variable-frequency drive (VFD) connected directly to a communications adapter.

  • In this version, OT Security detects nested devices only for Rockwell devices and Rockwell connection types such as CIP, DirectNet, ControlNet, DH+.

  • OT Security observes nested relationships between OT devices passively or through the Backplane Scan active query.

  • On the asset details page, Related Assets > Backplane view lists all related assets, and a icon indicates any nested devices beneath a module.

Asset Relationships - IoT Connectors

  • OT Security maps all managed IoT devices to their respective application server.

  • To view all managed IoT devices by a specific application server, you must configure the IoT engine and synchronize assets from the application server. In the example of an IP camera, you can see the VMS server that manages it. Navigating to this VMS server on the Inventory > IoT Connectors > Related Assets page lets you view all cameras that this VMS server manages.

Dynamic Fingerprinting Engine (DFE) Updates

You can now make Dynamic Fingerprinting Engine (DFE) updates from the cloud. Some key benefits of this feature are:

  • On-Demand Updates: Instantly download and apply the latest classification changes directly from the cloud, ensuring your inventory is always up to date.

  • Enhanced Flexibility: Access additional fingerprints without waiting for local updates or new version releases, providing immediate and continuous improvement.

  • Seamless Integration: Incorporate new fingerprints as they become available, receiving critical updates between major version releases for enhanced responsiveness.

    For more information, see DFE Updates.

Exportable Executive Summary Report PDF

  • OT Security now provides an option to generate and export an executive summary report in PDF.

  • To view and download the Executive Summary report, go to Dashboards > Monthly Report.

  • This feature is an enhancement to an earlier version of the OT Security reporting feature.

For more information, see Generate Monthly Report.

Asset Diagnostic Export report

  • You can now export a detailed diagnostic report of an asset for support purposes. You can also bulk export a diagnostics report for multiple assets. For more information, see Export Diagnostics.

Tenable Security Center Integration Enhancements

  • Starting with Tenable Security Center 6.4, integrating with OT Security brings additional context in Tenable Security Center.

  • After integration, OT Security asset details synchronize with Tenable Security Center. These asset details include: Name, Type, Category, Running State, Firmware Version, Vendor, Model, Family, Backplane Information, MAC, Purdue Level, Location, and Description.

  • There are no special configurations or settings for this feature apart from running the latest version of OT Security and Tenable Security Center.

Active Queries Management Redesign

  • Active Queries are now available as informative cards that you can customize as needed.

  • You can create Query variations for each type of Active Query and customize them as in the earlier versions.

  • A status column indicates whether active queries are running, stopped, or paused.

    For more information, see Active Queries Management.

Active Queries Management — Executions History

  • You can now download a CSV export of the last query execution details. If the active query targeted multiple assets or protocols, this information also appears in the exported results. During the initial setup, this helps troubleshoot queries against various assets. For more information, see Download Last Query Log.

Active Queries Management — 'Try Anyway' Button

  • You can now override the limit to the number of active query attempts during troubleshooting. OT Security now provides a Try Anyway option to proceed with active queries on devices or network when you make any firewall or network changes to those queries.

Active Queries Management — Ping Query Added

  • OT Security now includes a separate Ping query that relies on Internet Control Message Protocol (ICMP) to test whether an asset is routable or reachable. This query is essentially the same Ping query used during an Asset Discovery or Active Asset Tracking query.

Pendo Tool Integration

  • Resource Center: Access to various helpful resources directly within the application:

    Note: Access to the Resource Center requires an Internet connection.

    • Knowledge Base Search: Search the product Knowledge Base (KB) within the application for quick answers and information.

    • Feature Updates: Receive in-app notifications about the latest feature updates and new releases.

    • Welcome Flow for New Users: A high-level sneak peek showcases the main values and key product features to give you a quick tour.

Tenable One - Open Ports Findings

  • Along with assets and vulnerabilities, OT Security can now also synchronize open ports on monitored assets when integrated with Tenable One.

  • You can use open port information for assets for dynamic tagging and to reveal more potential attack paths that may lead to compromise.

Vulnerability State Tracking

  • OT Security now retains and displays mitigated (fixed) vulnerabilities.

  • You can now see Active versus Fixed vulnerabilities when viewing an asset or the overall vulnerabilities on the Vulnerabilities page.

  • Fixed vulnerabilities age out after one year.

Generic Protocol Parser

  • OT Security now uses a generic protocol parser that allows you to add protocol detection capabilities quickly. This parser is an internal tool used in Tenable research.

  • The generic parser relies on LUA scripts, and is powered by the embedded Suricata IDS engine.

Access Account Details from the "About" View

After activatingOT Security, you can view your Tenable customer ID in the About view.

To access this information, click your username in the upper-right corner of the interface and select About from the drop-down menu. This view displays your account details, including your customer ID. Note that this customer ID is required when contacting Technical Support or Customer Success teams.

    • Honeywell Code Upload

  • Siemens SICAM 8050 RTU — OT Security now supports Siemens SICAM 8050 RTU over SNMP v3. You can send queries directly to these devices to detect and fingerprint them. The active queries used to fingerprint these RTUs rely on SNMP v3, which requires an SNMPv3 credential.

Role-Based Access Control (ICP)

OT Security now includes the following changes to Local Settings > Users Management:

  • Product administrators can now configure permissions for user groups using Zones.

  • Configurable Zones based on asset groups.

  • These zones determine the assets that a user or group can view.

  • A user can only view assets that belong to the user's group along with assets, vulnerabilities, and events.

  • OT Security monitors the assets outside the zone but hides them from those outside the relevant zone.

  • You can configure non-admin accounts to be part of a specific group and zone to limit their visibility to relevant assets.

Enterprise Manager - Role-Based Access Control

OT Security EM now includes these changes in Local Settings > Users Management:

  • Includes settings that control visibility and administrative rights for each linked site.

  • You can now control which user groups can access each OT Security ICP.

  • You can now configure the permissions for users in both OT Security EM and ICP level. Each EM user can now access the linked ICPs and set the access for read-only or write access.

Enterprise Manager - Support for Authentication Providers (LDAP, AD, and SAML)

  • In OT Security EM, you can now leverage SSO providers (SAML) for authentication.

  • OT Security EM now supports configuration of AD and LDAP authentication.

Enterprise Manager - ICP-EM Pairing Process via the OT Security Interface

  • You can now use the Enterprise Manager page in OT Security to pair your ICP with OT Security EM. You can pair using an API key or username and password.

  • The Enterprise Manager page provides a step-by-step guide to pair your ICP with EM.

  • In OT Security, you can access the page from Local Settings > System Configuration > Enterprise Manager. For more information, see Pair ICP with Enterprise Manager.

Customizable Classification Banner

  • OT Security now includes a Classification Banner option in the Local Settings > Device page. You can use this option to enable a persistent banner on the OT Security interface for compliance purposes. For example: Add a banner "Confidential" to the interface.

  • In alignment with DFARS 252.204-7012, you can now set this banner accordingly for your CUI (Controlled Unclassified Information) or sensitive data.

  • Users cannot clear or hide this banner or classification marking. This global setting affects all OT Security users.

Tenable One — Findings and Weaknesses

  • If you integrated OT Security with Tenable One, you can now view and prioritize your OT Security vulnerabilities from within Tenable One without further configuration.

  • Once you upgrade to the latest release, you can access both asset context and vulnerability details within Tenable One.

Rediscovered Asset Policy

  • OT Security now includes a new policy: Rediscovered Asset.

  • The Rediscovered Asset policy allows you to track assets that are offline for a specific period of time.

  • The default policy name is "Asset Rediscovered after two hours of inactivity".

  • You can create this policy from Policies > Network Events > Rediscovered Asset.

Custom Threat Detection (IDS) Signatures

  • You can now manually upload all IDS-specific Indicators of Compromise (IoCs) to OT Security.

  • You can now import Suricata formatted IDS rules into OT Security by using the command line.

Syslog Event Alerts Cache ("Store and Forward")

  • In the event of a disrupted connection using TCP Syslog, OT Security caches events and sends them once the connection is re-established.

  • The Allow syslog message caching option is available when creating a new Syslog Server in Local Settings > Syslog Servers.

  • OT Security sends the cached events instantly in their queuing order while the connection was down.

Note: UDP syslog messages do not have any state awareness and may be lost if the connection is interrupted.

Enterprise Manager — Site Sensors Visibility

  • OT Security EM now includes the following two widgets specific to sensors:

    • Sensors Status: Indicates how many sensors are online versus offline.

    • Sensors per Site: Indicates the number of online or offline sensors per site linked to OT Security EM.

Enterprise Manager — Licensing

  • OT Security EM now includes in-product licensing to activate the console. Contact your Customer Success Manager if you do not have an activation code for your EM.

Enterprise Manager — Appliance Details

  • OT Security EM includes the following additional metrics about all paired OT Security appliances (ICPs):

    • CPU utilization, memory, disk, plugin and IDS timestamps, and license properties and consumption.

    • The Sensors column of the ICPs page shows the total number of sensors versus the number of online sensors. The column also includes a link to the Sensors page for that site.

New Configuration Flow for Authentication Servers

  • OT Security EM now includes a simplified workflow for the AD/SSO/LDAP configuration.

  • You can now assign user groups in OT Security to specific authentication servers.

  • The improved Authentication Servers workflow affects both OT Security and OT Security EM.

Support for KEV Plugin Property

Any vulnerabilities that OT Security detects that are on the Known Exploited Vulnerabilities (KEV) catalog from the U.S. Cybersecurity and Infrastructure Security Agency (CISA) now show their due date. The KEV catalog helps security teams prioritize which risks to fix first so that they mitigate the greatest threats to their organizations. For more information, see Known Exploited Vulnerabilities.
