Businesses, communities, and families across America depend on the reliable availability of oil and natural gas for countless functions of everyday life. Recognizing the criticality of the oil and natural gas (ONG) subsector to our shared security and prosperity, over 25 ONG organizations—with an emphasis on high-throughput midstream natural gas pipeline owner-operators–and their industrial control systems (ICS) vendors convened through the Joint Cyber Defense Collaborative (JCDC) to undertake the 2023 JCDC Pipelines Cyber Defense Planning Effort.

The 2023 JCDC Pipelines Cyber Defense Planning Effort was a novel approach to bring together pipeline owner-operators and their ICS vendors, in partnership with the Transportation Security Administration and Department of Energy, to address shared challenges – whether ransomware incidents like the 2021 intrusion into Colonial Pipeline or persistent targeting by threat actors like the People’s Republic of China who possess the capability to disrupt natural gas pipelines, as highlighted in the ODNI 2023 Annual Threat Assessment. An effective response to these threats demands public-private collaboration efforts to defend pipeline networks against compromise and ensure that they continue to function in a worst-case scenario.

This effort resulted in a detailed by-industry, for industry network architecture diagram and adjoining principles, the ONG Pipelines Reference Architecture. Pipeline owner-operators and ICS vendors built this architecture to serve as a voluntary model to guide their investment, planning, and operations as they work to better segment their networks and mitigate intrusion campaigns. The ONG Pipelines Reference Architecture offers practical guidance for stepping up risk management and showcases the interplay between network segmentation, multi-factor authentication (MFA), external dependencies, and critical field devices.

By organizing collaboration between midstream pipeline owner-operators and ICS vendors, this cyber defense planning effort facilitated a foundation for industry to proactively take transformative steps to harden the digital networks that run our nation’s largest natural gas pipelines against compromises – an example of the vision first established by the Cyberspace Solarium Commission and codified by Congress to catalyze cyber defense planning that yields real change in our nation’s cybersecurity.

One of CISA’s most important and enduring roles is providing timely and actionable cybersecurity information to our partners across the country. Nearly a decade ago, CISA stood up our Automated Indicator Sharing, or AIS, program to widely exchange machine-readable cyber threat information. We know that the only constant in cybersecurity is change, and we’re evolving our information sharing approaches to maximize value to our partners and keep pace with a changing threat environment.

How Did We Get Here?

Every day, CISA evaluates the cyber threat environment, considers the impact of known vulnerabilities, and assesses the defensive posture of entities across our Nation to determine how we can most effectively safeguard critical infrastructure and government networks. Our insight is derived from a variety of sources to include classified and open-source reporting; operational collaboration with government and industry partners; findings from CISA assessments and incident response; and from information shared by members of our broad cybersecurity community through mechanisms such as AIS.

CISA then translates these insights into timely and relevant information. We share information broadly on a global scale, through alerts, advisories, and our Known Exploited Vulnerabilities catalog. We enrich our shared services and cyber capabilities with cyber threat information (CTI). And we leverage these insights to design and prioritize new cyber capabilities for programs such as Continuous Diagnostics and Mitigation (CDM). Across the board, CISA incorporates our unique insights of the global cyber threat environment into everything we offer to provide value to our partners.

While these threat-informed products and capabilities are important to many of our stakeholders, we know that organizations also benefit from receiving cyber threat information to shape investment decisions and prioritize mitigation actions. It is not enough to monitor broad cyber threats generally; organizations must apply threat information to their own risk and technology environments. AIS was established to satisfy legislative requirements and to provide stakeholder communities with a cost-effective means by which to exchange cyber threat indicators and defensive measures with CISA and, in doing so, with thousands of cybersecurity practitioners across the country and with partners across the globe. When it was first established, AIS was a novel model that helped many organizations around the world. But now, it’s time for a change.

Where Are We Going?

As the cyber threat environment evolves, so must our capabilities to analyze and share cyber threat information. When AIS was first designed, the U.S. Government was focused on filling an identified gap in cyber threat intelligence for many organizations and ensuring strong privacy controls. In the early days of AIS, the priority was speed. A decade later, the cybersecurity industry has matured substantially; current products and services are addressing information requirements for most organizations and, in an era of information overload, practitioners still require speed but value context, precision, and tailored insights over volume and velocity alone.

In 2024, CISA will begin a strategic effort to modernize our approach to enterprise cyber threat information sharing. This effort will drive three key areas of progress:

- Simplification: We will refocus and consolidate our customer-facing cyber threat intelligence offerings under a new initiative called Threat Intelligence Enterprise Services (TIES). The TIES Exchange Platform will unify our information sharing capabilities under a single banner for federal agencies and certain user communities, enabling streamlined provision of cyber threat information from our partners and commercial sources. This will offer a common view which will facilitate communications and enable threat-specific engagement. As we design and implement this central solution, CISA is working in parallel to modernize our AIS capability which, in the future, will further complement CISA-curated threat feeds made available by this shared service platform.

- Partner-Centered Design: Throughout this process, we will be driven by the requirements of our partners, including federal agencies, critical infrastructure organizations, and state, local, tribal, territorial governments, to ensure that we are adding value rather than duplicating capabilities. We will continuously seek feedback and ensure that the platform itself is built around human-centered design principles to enable ease-of-use even for under-resourced organizations.

- Learning from Experience: We will rigorously learn from known challenges with the legacy AIS system: we know that it must be easy to both share and receive, that shared information must have sufficient context to enable prioritized action; and that every participant must recognize meaningful value that is additive to existing cybersecurity capabilities. At the same time, we will build upon the successes of the AIS program, including a rigorous focus on privacy and confidentiality by design.

What to Expect Next?

CISA's goal is to facilitate collective, automated cyber defense through increased sharing and context, shaped by an acute understanding of the threat environment. While CISA implements this transition over the next two years, the AIS program will remain available, and we encourage users to continue leveraging this capability and actively share indicators back with CISA.

The shared visibility into cyber threats is our best defense. When an organization identifies threat activity and keeps it to itself, our adversaries win. When we rapidly share actionable information across a community of partners, we take back the advantage. And, when we turn actionable information into strategic investments to drive the most important mitigations, we achieve enduring change. In this new year, we encourage every organization to make a commitment- perhaps a New Year’s resolution- to cybersecurity information sharing, including incident information, indicators of compromise, or even feedback and insights that could benefit peers across the Nation. We look forward to sharing more details about TIES and our cyber threat exchange modernization initiatives throughout the year.
