Disruptions to critical infrastructure can compromise governmental operations and defense mechanisms, posing significant national security threats. Economically, critical infrastructure serves as the backbone of a country’s economy, and ensuring its security is vital for sustaining economic growth and stability. Public safety and health heavily rely on the continuous operation of critical infrastructure services, and societal trust hinges on the ability of governments and private institutions to protect sensitive information and ensure the reliable operation of critical services.
Many sectors within critical infrastructure depend on outdated technologies in their industrial and operational environments, increasing the potential impact of successful cyberattacks. These legacy systems often lack essential security features needed to defend against modern cyber threats and rely on hardware and software that vendors no longer support. This situation poses a significant threat to society, necessitating urgent initiatives to strengthen defenses and ensure that vital systems can withstand current and future cybersecurity challenges.
The persistent use of outdated technology complicates effective cybersecurity and maintenance, leading to greater operational risks and inefficiencies. As systems become more interconnected and our reliance on critical infrastructure grows, the potential consequences of disruptions from natural disasters, terrorism, or cyber threats are amplified. The interconnected nature of modern critical infrastructure means that a breach in one sector can have cascading effects across others. This interdependency amplifies the potential impact of cyberattacks and necessitates a comprehensive approach to Critical Infrastructure Protection.
Emerging Cyber Threats to Critical Infrastructure
Cyber threats to critical infrastructure are diverse and can originate from various sources, including state actors, criminal organizations, terrorists, and other malicious entities. These threats range from sophisticated cyberattacks designed to destabilize essential services to attempts aimed at stealing sensitive information.
The implications of such attacks are profound, potentially leading to significant disruptions in public services, economic instability, and compromised national security. Recognizing the critical need to protect these vital systems, the U.S. government and other entities have taken significant steps to enhance cybersecurity measures.
In the U.S, the Cybersecurity and Infrastructure Security Agency (CISA) plays a pivotal role in this effort. CISA provides comprehensive guidelines, resources, and support to help organizations strengthen their Critical Infrastructure Protection and defenses against cyber threats. Key initiatives include:
- Vulnerability Management: CISA’s National Vulnerability Database (NVD) serves as a comprehensive repository of known cybersecurity vulnerabilities, enabling organizations to identify and address weaknesses in their systems.
- Incident Response and Recovery: CISA’s Cyber Incident Response Playbook outlines best practices for organizations to prepare for, respond to, and recover from cybersecurity incidents, minimizing the impact on critical operations.
- Information Sharing and Coordination: CISA facilitates the sharing of threat intelligence and cybersecurity best practices among government agencies, private sector partners, and international allies, fostering a collaborative approach to critical infrastructure protection.
- Sector-Specific Guidance: CISA provides tailored cybersecurity guidance and resources for each of the 16 critical infrastructure sectors, addressing the unique challenges and vulnerabilities within these industries.
The implications of cyber threats to critical infrastructure extend beyond immediate disruptions. Long-term impacts can include:
- Economic Consequences: Cyberattacks can cause significant financial losses, disrupt supply chains, and erode investor confidence, undermining a country’s economic stability and prosperity.
- National Security Risks: Compromises to critical infrastructure can weaken a nation’s defense capabilities, impair emergency response, and enable adversaries to gather intelligence or exert geopolitical influence.
- Public Health and Safety Concerns: Disruptions to essential services like healthcare, water treatment, and transportation can directly threaten the well-being and safety of the general public.
- Erosion of Societal Trust: Successful cyberattacks on critical infrastructure can undermine public confidence in the ability of governments and private institutions to protect sensitive information and ensure the reliable operation of essential services.
Tackling cyber risk and boosting resilience in critical infrastructure necessitates a thorough and unified strategy. This strategy should encompass developing solid cybersecurity frameworks and risk management practices that defend against threats and reduce the impact of incidents when they occur. Organizations must increasingly embrace a collaborative cybersecurity approach, particularly in integrating their IT, OT, and IoT infrastructures.
Global cooperation and compliance with established cybersecurity norms play a crucial role, as illustrated by worldwide discussions on state behavior in cyberspace and regulatory measures such as the European Union’s NIS2 Directive. To ensure effective Critical Infrastructure Protection, fostering a culture of ongoing cybersecurity vigilance and implementing standardized regulations across sectors and countries is critical. This approach helps manage the widespread effects of cyberattacks that can simultaneously affect multiple sectors.
Emerging Threats and Trends in Critical Infrastructure Cybersecurity
The rise in high-impact attacks underscores the necessity for continuous updates in strategies and capabilities, including enhancing detection technologies, promoting intelligence sharing across critical sectors, and adhering to strict cybersecurity guidelines and frameworks.
The Expanding Threat Surface: Connecting OT to the Internet
The adoption of connected Operational Technology (OT) has been accelerated by improvements in technology, making it even easier to connect devices remotely and at scale, including 5G and satellite Internet infrastructure. While connecting OT brings many benefits, it also increases critical infrastructure providers’ vulnerability to cyber threat activity.
Connecting OT to an Internet-connected IT network provides a pathway for threat actors to access and disrupt sensitive OT devices and processes. Threat activity against the IT network can have incidental effects on the OT network, with operators potentially shutting down OT processes out of caution or IT malware accidentally spreading and affecting OT.
We are also observing an increase in the use of malware that directly targets and disables OT. Cybercriminals have deployed OT-specific ransomware, and state-sponsored actors have demonstrated the capacity to deploy malware against critical infrastructure to degrade its performance and damage OT and IT assets.
Supply Chain Vulnerabilities
Critical infrastructure providers are reliant on their vendors and suppliers for expertise and equipment as they operate, maintain, and modernize their OT processes. This makes them particularly vulnerable to supply chain compromises, where cyber threat actors first compromise a vendor and use that access to compromise one or more of their clients.
Cyber threat actors target critical infrastructure supply chains for two purposes: to steal intellectual property and information about the OT deployed by a critical infrastructure provider and to obtain indirect access to networks.
Financially Motivated Attacks
Financially motivated cyber threat actors, predominantly cybercriminals, exploit critical infrastructure because downtime can be harmful to their industrial processes and the customers they serve. Cybercriminal activity against critical infrastructure can interrupt operations that support essential services, utilities, and the production of important goods, including food, fuel, and medical equipment, in support of their extortion demands.
For the healthcare sector in particular, the impacts of cybercriminal activity can be significant. Since March 2020, over 400 healthcare organizations in Canada and the United States experienced a ransomware attack, disrupting medical services and access to critical information.
State-Sponsored Threats
State-sponsored actors target critical infrastructure to collect information through espionage, to pre-position in case of future hostilities, and as a form of power projection and intimidation. While we assess that state-sponsored actors are very unlikely to intentionally disrupt Canadian critical infrastructure in the absence of direct hostilities, the state-sponsored cyber programs of China, Russia, Iran, and North Korea continue to pose the greatest strategic cyber threats.
The invasion of Ukraine has demonstrated that Russia is increasingly willing to use cyber activity against critical infrastructure as a foreign policy lever. The Cyber Centre has issued cyber threat bulletins advising of foreign cyber threat activities, including by Russian state-sponsored threat actors, targeting Canadian critical infrastructure network operations and OT.
