Letter from Leadership

Welcome to CISA’s 2023 Year in Review. We hope you enjoy this interactive format and encourage you to explore each topic in more depth by clicking the embedded links. This past year has brought an added layer of complexity as we start to tackle the implications of widespread use of Artificial Intelligence, grapple with the ripple effects of overseas conflict, and continue to execute our role as the nation’s cyber defense agency and national coordinator for critical infrastructure security and resilience.  

As we have said many times over the past years, no single agency, organization, or individual can see the full threat picture. It takes partnership, and that is at the core of how we achieve our mission. As you read through this year’s report, know that behind many or even most of these achievements lie strong collaboration with our many partners at home and abroad.  

2023 also marked CISA’s 5th anniversary since the agency was established in 2018. See how we have evolved over the past five years:

Mission: We lead the national effort to understand, manage, and reduce risk to our cyber and physical infrastructure.

Vision: Secure and resilient critical infrastructure for the American people. 

With Gratitude, 

Leadership signatures

In 2023, CISA prioritized engagement and cybersecurity within “target rich” sectors, including water and wastewater, K-12 education, and healthcare and public health.

Snapshot: CISA's Target Rich Initiative

Over the past year, CISA worked closely with the Water and Wastewater Sector, Education Facilities (K-12) Sector/Subsector, Healthcare and Public Health Sector, and the Elections Subsector. These sectors often have few resources to invest in security and resilience and are at high risk from adversaries who see them highly desirable targets.

As part of its efforts, CISA completed nearly 6,700 stakeholder engagements with government and private sector participants in 2023. This includes:

  • Almost 2,700 engagements for the Healthcare & Public Health Sector
  • More than 1,700 engagements for the Water & Wastewater Sector
  • More than 2,200 for K-12 Sector engagements
K-12 Cybersecurity

In January 2023, CISA published its Protecting Our Future: Partnering to Safeguard K-12 Organizations from Cybersecurity Threats report and toolkit which identify cybersecurity risks to K-12 schools while also providing recommendations to help schools face these risks.

In September 2023, CISA announced a voluntary pledge for K-12 education technology software manufacturers to commit to designing products with greater security built in. As of October 2023, 11 companies have signed on.         

CISA is also dedicated to strengthening the physical security and safety of schools across the country. In 2023, we:

To help improve cybersecurity within the Healthcare and Public Health (HPH) Sector, CISA, the Department of Health and Human Services (HHS)—the sector risk management agency for healthcare—and the Health Sector Coordinating Council Cybersecurity Working Group worked together over the past year to deliver tools, resources, training, and information that can help organizations within this vitally important sector.

CISA reached a key milestone in its collaboration with HHS as it rolled out a joint HPH Cybersecurity Toolkit in October at a partner roundtable co-hosted with HHS.

Through its National Cyber Exercise Program, CISA also published the HPH Sector CISA Tabletop Exercise Package (CTEP). The HPH Sector CTEP is a tabletop exercise-in-a-box to help members of the HPH Sector increase their cyber resilience. It allows organizations to customize an exercise to fit their needs by modifying its scenario and discussion questions.

CISA strengthens the security and resilience of cyberspace by offering a range of services and resources focused on operational resilience, cybersecurity practices, and other key elements of a robust and resilient cyber framework.

In October 2023, CISA and 17 U.S. and international partners published an update to “Shifting the Balance of Cybersecurity Risk: Principles and Approaches for Secure by Design Software,” originally released April 13, 2023. The updated guidance integrated feedback received from hundreds of individuals, companies and non-profits, and eight new international agency co-sealers.

Secure by Design logo

This paper urges software manufacturers to revamp their design and development programs to permit only secure by design products to be shipped to customers and lays out three core principles:

  1. Take Ownership of Customer Security Outcomes
  2. Embrace Radical Transparency and Accountability
  3. Lead from the Top

CISA additionally released our first Secure by Design Alerts reflecting the real-world harm created by technology products that are released with known defects, such as exposed web interfaces and default passwords.

CISA notifies thousands of organizations about intrusions and vulnerabilities, allowing mitigation before damage occurs, avoiding millions of dollars of impacts and real harm to public health and safety.

CISA’s Pre-Ransomware Notification Initiative measurably reduces risk by warning organizations of early-stage ransomware activity. In 2023 we conducted more than 1200 pre-ransomware notifications to include 7 Water and Wastewater sector entities, 20 Transportation System sector entities; 17 Energy sector entities; 117 U.S. and 19 international K-12 school districts; 111 U.S. and 27 international institutes of higher education; 154 U.S. healthcare organizations; 39 U.S. Emergency Services sector entities; and 94 U.S. state, local, tribal, and territorial governments. 294 pre-ransomware notifications were also shared with 27 partner countries. 

See it in action: 

  • In February, CISA supported a Fortune 500 company suffering a $60M ransomware attack. This support led the company to establish a Chief Information Security Officer (CISO) position, make significant investments to their IT architecture, and implement improved security controls to be more cyber resilient. Additionally, CISA and the FBI held a joint cyber threat brief to provide more regional support.  

  • In 2023, CISA provided a notification to a mass transit partner, preventing a $350 million ransomware attack on critical transportation infrastructure.  

Through our Administrative Subpoena authorities, granted by Congress in 2021, we identified and drove mitigation of over 690 vulnerable devices used to control critical infrastructure such as power plants and water utilities.  

Through our Ransomware Vulnerability Warning Pilot, we conducted more than 1,700 notifications to organizations, including hospitals, water utilities, K-12 school districts, and election jurisdictions about open vulnerabilities on their networks that are specifically exploited by ransomware actors and enabled timely mitigation before intrusions occurred. This program is driven by our Vulnerability Scanning efforts, which now covers nearly 7,000 critical infrastructure and SLTT entities in every state.  

In 2023, CISA conducted more than 240 Cybersecurity Performance Goals (CPGs) assessments across the agency’s 10 regions nationwide. CISA released the CPGs in late 2022 to provide organizations of all sizes, across all sectors, and at every level of cyber maturity with clear, plain language cybersecurity recommendations. When implemented, the CPGs can help these entities reduce the impact of the most common or most impactful cyberattacks.

In 2023, CISA’s Joint Cyber Defense Collaborative (JCDC) initiated a collaborative cyber defense planning effort to support the awareness, security, and cyber resiliency of open source software in Operational Technology and Industrial Control Systems. By embracing open source principles, CISA not only champions inclusivity, but also fortifies the nation’s defenses against evolving threats.

In September 2023, CISA unveiled its Open Source Software Security Roadmap, marking a pivotal moment in bolstering national resilience. These comprehensive frameworks delineate a strategic path forward, fostering transparency, collaboration and innovation within the cybersecurity landscape.

On November 14, 2023, CISA published its first Roadmap for Artificial Intelligence (AI). This Roadmap outlines a whole-of-agency plan aligned with national strategy to promote the beneficial uses of AI to enhance cybersecurity capabilities, ensure AI systems are protected from cyber-based threats, and deter the malicious use of AI capabilities to threaten the critical infrastructure Americans rely on every day.

CISA Roadmap for AI

Shortly after the Roadmap publication, CISA and the United Kingdom’s National Cyber Security Centre jointly released Guidelines for Secure AI System Development addressing the intersection of AI and cybersecurity. Developed in cooperation with 21 other agencies and ministries from across the world, the Guidelines for Secure AI System Development are the first of their kind to be agreed to globally and will help AI system developers make informed cybersecurity decisions at every stage of the development process.

The Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA) requires CISA to develop and implement regulations requiring covered entities to report covered cyber incidents and ransomware payments to CISA. This will enable CISA to use reported information to fill critical information gaps, rapidly deploy resources, and render assistance to entities that are negatively impacted by cyber incidents, analyze and spot trends, and quickly share that information with network defenders to warn other potential victims.

This will enable CISA to use reported information to fill critical information gaps, rapidly deploy resources, and render assistance to entities that are negatively impacted by cyber incidents, analyze and spot trends, and quickly share that information with network defenders to warn other potential victims. 

Throughout the year, CISA also continued to consult with Federal interagency partners during the development of the CIRCIA Notice of Proposed Rulemaking (NPRM). CISA reviewed the comments and other stakeholder inputs received and took those into consideration while drafting the NPRM. 

Recognizing that technology is an integral part of our modern lives, Congress tasked CISA with creating a cybersecurity awareness program to provide small businesses, communities and individuals with the guidance and tools they need to protect themselves online. CISA answered the call by launching the Secure Our World program in September 2023. We also engaged with Google, Microsoft, Mastercard, National Cybersecurity Alliance, and Global Cybersecurity Alliance, to reach a variety of audiences across the nation.

The program emphasizes four simple steps everyone should implement and continuously improve upon:

  • Use strong passwords and a password manager.
  • Turn on multifactor authentication.
  • Recognize and report phishing.
  • Update software.

The campaign featured CISA’s first-ever Public Service Announcement. The agency also collaborated with several government agencies and private sector organizations to promote the program. CISA worked with the Transportation Security Agency to produce a joint video sharing how everyday citizens can Secure Our World.

CISA is the operational lead for federal cybersecurity, charged with protecting and defending federal civilian executive branch networks (FCEB).

In 2023, we: 

  • Identified and drove mitigation of more than 14 million Known Exploited Vulnerabilities across the federal government using our Continuous Diagnostics and Mitigation (CDM) program and our Vulnerability Scanning tools. Across non-federal partners, we have driven mitigation timelines to be 36 days faster than a year ago.  

  • Onboarded 97 agencies onto our Protective Domain Name System service, which blocked 900 million malicious connections targeting federal agencies, disrupting a significant number of attempted attacks. Using new authorities from Congress, we are now deploying this same capability to under-resourced critical infrastructure organizations such as K-12 school districts and water utilities, with over 20 organizations already on board and nearly 100 in the deployment process. 

  • Onboarded 46 agencies onto the Vulnerability Disclosure Policy Platform, leading to identification and remediation of 1,054 confirmed vulnerabilities before they could be exploited by malicious actors.

  • Released multiple new open source tools to help the cybersecurity community, including Secure Cloud Business Applications tools for both Microsoft and Google cloud services. 

  • Issued two Binding Operational Directives, BOD 23-01 and BOD 23-02, resulting in real-time asset visibility across every federal agency and remediation of hundreds of exposed Network Management Interfaces. 

  • Continued to deploy advanced endpoint protections to nearly 50 federal agencies, reaching over 900,000 devices. These technologies give CISA unsurpassed visibility into threats and incidents targeting federal networks, allowing faster detection. Using new authorities and resources provided by Congress, we can now help agencies respond to cyber events in minutes rather than days or weeks. 

  • Led and coordinated the response to numerous significant incidents, including the compromise of Microsoft Exchange Online, which resulted in systemic changes to improve cloud security for all Microsoft customers.

Partnerships and collaboration are our foundation and the lifeblood of what we do. Through our operational outreach, Industry Engagement Program, and contract activities, CISA continues to stress our strong industry engagement.

In August 2023, CISA kicked off a broad effort to promote resilience across critical infrastructure by communicating the imperative principles and priorities of resilience in accessible and meaningful ways and empowering stakeholders to take action where they are and ask for support for where they want to be. A key part of this effort was the November launch of Shields Ready, CISA’s campaign to encourage the critical infrastructure community to focus on strengthening resilience.

Shields Ready, which complements CISA’s successful “Shields Up” campaign, focuses more broadly and strategically on how to prepare critical infrastructure for a potential disruption and how to build more resilience into systems, facilities and processes by taking action before a crisis or incident even occurs. Shields Ready aligns with and complements FEMA’s Ready campaign and is a call to action to prioritize resilience now.

Throughout the year, the JCDC, which plays a crucial role in enhancing the nation’s cyber resilience and safeguarding critical infrastructure, continued to evolve and adapt to the ever-changing cyber threat landscape, achieving remarkable results.

Joint Cyber Defense Collaborative

Its remote monitoring and management capabilities were highlighted in the 2023 JCDC Remote Monitoring and Management Cyber Defense Plan. By leveraging cutting-edge technology and collaborative efforts, the JCDC demonstrated an unparalleled ability to proactively detect and respond to cyber threats. With a focus on real-time threat intelligence and rapid response, the JCDC’s efforts led to a significant reduction in response times, ultimately safeguarding critical systems and networks across various sectors.

JCDC in Action: JCDC Participants Share Real-Time Threat Information on NetScaler Vulnerability Post-Exploitation Activity

  • Since July 2023, JCDC participants, including Mandiant, Shadowserver, GreyNoise, and ZeroFox, have provided continuous insight into post-exploitation activity of the NetScaler (formerly Citrix) Application Delivery Controller and NetScaler Gateway vulnerability (CVE-2023-3519). Recognizing the importance of open multi-directional communication, CISA established real-time information sharing with industry partners possessing advanced insight into exploitation of the vulnerability.

As we look forward in 2024, the risks we face now will continue to evolve. Advanced persistent threat actors like China threaten the integrity of our critical infrastructure. Increasingly severe weather, wildfires, and other natural hazards are creating additional risks that critical infrastructure facilities must work into their planning. Extremists are likely to continue to target organizations that are meant to be open and welcoming—such as faith-based communities. Artificial intelligence will continue to evolve at an awe-inspiring pace, bringing with it both potential for good and new opportunities for bad actors. And 2024 is promising to be an election year like no other.  

Despite the risks surrounding us, America was designed to be resilient. This country has faced and overcome numerous challenges since its inception, and we will continue to do so—together. There is no total guarantee of a risk-free, completely secure environment, so we must all plan and prepare to be recover quickly if—and when—we face a crisis.  As the nation’s cyber defense agency and national coordinator for critical infrastructure security and resilience, CISA will continue to develop and deliver tools, training, technical expertise, and other resources to help our critical infrastructure partners increase their own resilience to evolving risks. It is also incumbent on every organization, large or small, to take responsibility for their own security and resilience. Therefore, we challenge everyone to make 2024 the year we Resolve to be Resilient.
