Nearly 100 large community water systems in the U.S. possess serious cybersecurity vulnerabilities, risking water supply for 27 million Americans. Despite regulations, financial and resource constraints hinder proper security measures. Cyberattacks from various groups have targeted water systems, emphasizing a critical need for improved investment and security practices in this sector.
### Meeting Takeaways
1. **Cybersecurity Vulnerabilities in Water Systems**:
– Nearly 100 large Community Water Systems (CWS) have serious vulnerabilities in their Internet-facing systems, jeopardizing the water supply of approximately 27 million Americans.
– Over 9% of the 1,062 water systems serving at least 50,000 people in the U.S. were identified with critical and high-severity issues according to an EPA report dated November 13.
2. **Impact of Vulnerabilities**:
– Millions rely on affected water systems, including citizens, businesses, schools, and hospitals.
– Exploitation of these vulnerabilities by malicious actors could potentially disrupt service or cause significant physical damage to infrastructure.
3. **Increased Targeting of Water Systems**:
– Water systems have increasingly come under cyberattacks from state-sponsored groups, ransomware gangs, and hacktivists, notably highlighting incidents from Iran and previous attacks on systems in Florida and Pennsylvania.
4. **Challenges Specific to Water Utilities**:
– Water utilities face unique operational technology (OT) cybersecurity challenges due to their direct impact on public health and the geographical spread of their infrastructure.
– Many are small agencies with limited resources and outdated technology, complicating their ability to enhance security measures.
5. **Regulatory Compliance Issues**:
– Water systems serving over 3,300 people are required by regulation to conduct risk and cybersecurity assessments but often lack funds to fulfill these obligations.
– The EPA warns that many systems fail to implement basic security best practices, like changing default passwords.
6. **Call for Greater Investment**:
– Experts indicate that simply increasing regulations is insufficient without addressing the financial constraints that utilities face.
– Greater investment from federal or state governments is necessary to enhance cybersecurity defenses in the water sector.
7. **Legacy Infrastructure Challenges**:
– The aging infrastructure and the extent of legacy technology in operation create additional hurdles for securing water systems against cyber threats.
### Next Steps
– Further discussions and planning on how to address financial constraints for water utilities.
– Assessment of potential federal or state investment options to enhance cybersecurity measures.
– Development of a strategy to improve awareness and training regarding basic cybersecurity practices among water system staff.
