Addressing U.S. Dept. of Energy Cybersecurity Considerations

CHALLENGE

Selecting an ICS Monitoring Solution that Meets/Exceeds
DOE Considerations

Escalating attacks on critical infrastructure have spurred the U.S. government to take numerous actions to accelerate improvements in cyber resiliency.

This includes a Department of Energy (DOE) initiative to improve the ICS cybersecurity of electric utilities. To that end, the DOE developed a set of 17 considerations for evaluating ICS/OT monitoring technology for the electricity subsector. They can be found here.

The Nozomi Networks solution helps you meet and exceed DOE recommendations.

Meeting and Exceeding
the 17 DOE Considerations

According to DOE guidance, the U.S. government does not select, endorse or recommend any specific technology or provider as part of their initiative. Instead, each entity must assess and select the technology or provider that’s best for it.

Furthermore, the agencies that  developed the 17 DOE recommendations (CESER, CISA and the NSA) state:

The highest priority for the Industrial Control Systems (ICS) Cybersecurity Initiative is for owners and operators to enhance their detection, mitigation, and forensic capabilities.”

With that in mind, the table below lists each of the DOE considerations and describes how the Nozomi Networks solution addresses each of them.

  • Provides “always on” continuous monitoring of OT, IoT and IT protocols for assets from all vendors
  • Analyzes network communications using protocol-specific Deep Packet Inspection (DPI) for dozens of industrial protocols

  • Detects cybersecurity and process reliability threats

  • Accelerates incident response with actionable intelligence and time-saving response tools

The Nozomi Networks Solution is Built for ICS Networks and Protocols

A key requirement for good cybersecurity is identifying all assets in the ICS environment and mapping the communications between them.

The Nozomi Networks solution automates asset inventory and provides real-time visualization that identifies communication and other issues. This improves situational awareness and accelerates incident response.

Technology
that Shares Information

Nozomi Networks Solution

3

Technology software that has a collective-defense capability/framework to allow the sharing of insights and detections rapidly with the Federal government, participants, and trusted organizations such as relevant information sharing and analysis centers (ISACs)/information sharing and analysis organizations (ISAOs). Data and insights collected must be sharable across the Federal government, to the greatest extent possible, and should be compatible with other sector sensing partnerships.

  • Provides highly accurate ICS attack, vulnerability, and anomaly data, the foundation for information sharing
  • Integrates out-of-the-box with SIEM/SOAR, threat sharing platforms, and other products for rapid information-sharing across the organization and beyond
  • Shares data more broadly via reporting and exporting capabilities, as well as through an Open API
  • Receives continuously updated Threat Intelligence and Asset Intelligence, reducing the Mean-Time-to-Detect (MTTD) and the Mean-Time-to-Respond (MTTR)

4

Technologies that do not collect or store sensitive data off the participants’ site (e.g., perform analysis at the edge); however, certain insights or analysis outputs, such as whether a threat was present and relevant indicators of compromise, may be stored off premises.

  • Provides customizable data storage options
  • Available in the widest range of on-premises hardware/virtual/software sensor options
  • Analyzes data 100% within the sensor, without the need for input from outside analysts or remote access connections
  • Shares data off premises via optional cloud product (Vantage), integration with many IT, OT and security products, or via an Open API

5

Technologies must protect or anonymize participant identity, and ensure that risks and vulnerability information is not inadvertently disclosed between participants unless explicitly authorized by the participating entity.

  • Protects participant identity when sharing sensitive data
  • Granular anonymization features are in development

Technology that Correlates Data and Has Flexible Data Storage

Nozomi Networks Solution

6

The technology allows for centralized queries and correlation. Sensitive information that contextualizes anomalies that may indicate adversary presence may be stored off-premises for analysis.

  • Includes powerful query capabilities, providing fast access to security and operational data
  • Queries can be imported/exported between systems
  • Data can be aggregated with on-premises CMC or cloud-based Vantage.

7

Technologies that do not collect or store sensitive data off the participants’ site (e.g., perform analysis at the edge); however, certain insights or analysis outputs, such as whether a threat was present and relevant indicators of compromise, may be stored off premises.

  • Stores data short-term or medium-term (> 1 year)
  • Allows tuning of raw data collection for relevant streams
  • Provides long-term storage via SIEM integration and automated data exports for data warehousing

8

The technology is passive in its deployment, using isolation technologies to ensure that the technology itself cannot be used as a vector for adversaries to gain access into sensitive ICS networks.

  • Conducts passive network analysis
  • Select from the widest array of hardware/virtual/software sensor options
  • Works in air gapped environments, without cloud or remote analyst connectivity

9

The ICS sensing technology is capable of working with correlation and aggregation technologies to allow for OT/IT sensing cross correlation and analysis.

  • Integrates with SIEM and other IT and security tools for IT/OT correlation of data
  • Combines vulnerability assessment, threat and anomaly detection, asset inventory and risk monitoring in a single tool. Internal correlation of data reduces some cross-tool requirements.

The Nozomi Networks Solution Includes Many On-Premises Sensors with Flexible Data Storage & Aggregation Options

The Nozomi Networks solution is available in a wide-range of on-premises sensors.

In addition, a SaaS-powered solution, Vantage, is available for those companies who want to analyze data or share information in the cloud.

The Nozomi Networks Solution Supports the MITRE ATT&CK for ICS and Enterprise Frameworks

The Nozomi Networks solution associates malicious activity with techniques in the MITRE ATT&CK for ICS and Enterprise frameworks.

For example, a request to stop a process using the well-known TRITON malware generates an  “OT Device Stop Request” alert.

Included in the alert is the Change Program State technique (T875), which is associated with both Execution and Impair Process Control tactics.

This information helps analysts understand the behavior and improves response time.
