A Critical Investment in Cybersecurity for Rural Water Systems

The Importance of Funding for Small Organizations

A recent bill proposing $7.5 million in annual cybersecurity funding for US rural water systems is receiving attention for the impact it could have on covered entities. While the dollar amount may seem relatively small, this funding would provide a much-needed infusion of cash for a critical infrastructure sector that plays a significant role in public safety.

Rural water systems, despite serving smaller customer bases, are essential for providing clean and safe water to communities across the country. However, these systems have traditionally had limited cybersecurity capabilities, making them attractive targets for attackers. The disruption of water and wastewater systems can lead to public health emergencies, and the vulnerabilities in these systems can be exploited by activists and volunteers who seek to undermine confidence in the government’s ability to maintain critical services.

Security Risks and Potential Consequences

There are serious concerns surrounding the cybersecurity of small water facilities. Attackers could exploit critical operating systems to drain tanks, change chemical levels, inject false telemetry information, or disrupt waste treatment operations. The consequences of such attacks go beyond shutting off water; they could cause mass sickness and even death if attackers manipulate the chemical balances in the water supply.

Additionally, smaller organizations are often easier targets for attackers, as they require fewer resources to breach. This raises concerns about diversion tactics, where attacks on small and rural water systems may be used to divert attention from larger, more significant targets.

Averting Future Attacks

Fortunately, there have been few publicly reported attacks on small and rural water systems of major significance. However, this does not mean that these entities are immune to opportunistic attacks, including ransomware. The exposure of critical systems to enterprise and internet-facing users increases the likelihood of exploitation by threat actors.

In light of these risks, the proposed investment in cybersecurity funding for rural water systems is crucial. While $7.5 million may seem like a small amount, it specifically targets water entities that serve a population of 10,000 or less. For these very small water utilities, any financial assistance goes a long way in building their cybersecurity capabilities.

The bill seeks to expand the National Rural Water and Wastewater Circuit Rider program, which has been providing technical assistance to small and rural water systems for decades. Under this program, cybersecurity experts known as circuit riders will travel to rural facilities and help them design and implement cybersecurity plans. The funding will also support the development of governance and risk management programs for these entities.

The Significance of Targeting Small Utilities

When evaluating the effectiveness of the proposed cybersecurity funding, it is essential to consider the size and scope of the target audience. The bill’s tight scoping, focused on small utilities typically outside the scope of state and local cybersecurity grant programs, makes the $7.5 million investment significant. Private sector water systems in rural areas can utilize these funds to conduct required assessments mandated by the Environmental Protection Agency (EPA).

Accurate data on the number of rural water systems in the US is difficult to obtain due to classification challenges. However, it is estimated that around 97% of public drinking water systems serve populations of 10,000 or fewer. The funding provided by this bill would help these smaller entities identify and address security gaps in their systems, ensuring the continued delivery of safe water to communities.

Editorial: Safeguarding Critical Infrastructure and Public Health

Protecting critical infrastructure, including water systems, is crucial for public safety and national security. The proposed cybersecurity funding for rural water systems represents a significant step towards improving the security posture of these critical entities. It acknowledges the unique vulnerabilities faced by small utilities and the need for targeted support to enhance their cybersecurity capabilities.

As we have seen with recent cyberattacks on critical infrastructure sectors such as energy and transportation, ensuring the security and resilience of these systems is of paramount importance. By investing in cybersecurity funding for rural water systems, we not only protect public health but also send a message that the government is committed to safeguarding essential services.

Advice: Strengthening Cybersecurity in the Water Sector

To further enhance cybersecurity in the water sector, it is essential for small and rural water utilities to take proactive measures. Here are some recommendations:

1. Assess Vulnerabilities:

Conduct thorough assessments of systems, networks, and critical infrastructure to identify vulnerabilities. This will help prioritize security investments and mitigate potential risks.

2. Implement Best Practices:

Adopt industry-leading cybersecurity best practices, including strong access controls, regular system updates and patching, employee training on phishing and other social engineering tactics, and robust incident response plans.

3. Collaborate and Share Information:

Engage with industry associations, government agencies, and peer organizations to share cybersecurity information, best practices, and lessons learned. Collaboration can help raise awareness and build a community focused on improving cybersecurity resilience in the water sector.

4. Invest in Training and Resources:

Provide training and resources to staff members responsible for managing and securing water systems. This includes training on cybersecurity awareness, incident response, and technical skills needed to protect critical infrastructure.

5. Regular Testing and Auditing:

Conduct regular penetration testing and security audits to assess the effectiveness of existing security controls. This will help identify potential weaknesses and areas for improvement.

By implementing these measures, small and rural water utilities can strengthen their cybersecurity defenses and mitigate the risks posed by cyber threats. The proposed cybersecurity funding is a step in the right direction, but it should serve as a catalyst for broader investments in securing critical infrastructure across all sectors.
