Do You Check for Overly Permissive Network Access?
A recent survey conducted by the Water Sector Coordinating Council found nearly 60% of respondents reported conducting cybersecurity risk assessments less than once a year or never.
While the digitization of water and wastewater systems brings operational efficiencies, it also introduces new risks, particularly in terms of cybersecurity.
Water and wastewater infrastructure is considered part of critical infrastructure, and any compromise in the cybersecurity of these systems could have severe consequences for public health and safety. Cyberattacks on water utilities could potentially lead to contamination of water supplies, disruptions in service, or even physical damage to infrastructure.
To address these concerns, there is a heightened emphasis on enhancing network visibility for cybersecurity in the water and wastewater industry. This involves deploying advanced monitoring and detection systems to continuously assess the integrity of the network, identify potential vulnerabilities, and detect anomalous activities that could indicate a cyber threat.
One notable challenge is that many water utilities may have legacy systems that were not originally designed with robust cybersecurity features. Upgrading and securing these systems while maintaining continuous operations is a complex task that requires a strategic approach to network visibility and cybersecurity.

Water & Wastewater FAQ
The water and wastewater sector faces various cybersecurity vulnerabilities that could have significant consequences if exploited. Some of the key vulnerabilities include:
SCADA and Industrial Control Systems (ICS) Vulnerabilities:
- Many water and wastewater facilities rely on Supervisory Control and Data Acquisition (SCADA) systems and ICS to monitor and control their operations. Vulnerabilities in these systems can be exploited to manipulate processes, disrupt operations, or cause physical damage.
Legacy Systems and Outdated Infrastructure:
- Some facilities in the water sector still use legacy systems that may have outdated security protocols and lack the latest security updates. These systems are often more susceptible to attacks as they may have known vulnerabilities that have not been patched.
- Increasing connectivity between IT (Information Technology) and OT (Operational Technology) systems in the water sector creates additional points of entry for cyber attackers. If proper security measures are not in place, a compromise in one system could lead to vulnerabilities in others.
Inadequate Security Awareness and Training:
- Personnel in the water sector may not always be adequately trained in cybersecurity best practices. Human error, such as falling victim to phishing attacks or using weak passwords, can contribute to vulnerabilities.
Supply Chain Risks:
- Dependence on third-party vendors for equipment and software introduces supply chain risks. If these vendors have weak cybersecurity practices or if their products have vulnerabilities, they could be exploited to compromise the water and wastewater systems.
Insufficient Incident Response and Recovery Plans:
- Some facilities may lack comprehensive incident response and recovery plans. In the event of a cyber attack, a delayed or inadequate response can exacerbate the impact and prolong downtime.
Physical Security Weaknesses:
- Physical security is as important as cybersecurity in protecting critical infrastructure. Unauthorized physical access to facilities, equipment, or control systems could lead to compromise.
Lack of Regular Security Audits and Assessments:
- Regular cybersecurity audits and assessments are crucial for identifying and addressing vulnerabilities. Some facilities may not conduct these assessments regularly, leaving potential weaknesses undiscovered.
Dependency on Remote Monitoring and Control:
- While remote monitoring and control systems provide operational flexibility, they also introduce additional cybersecurity risks. If not properly secured, these systems can be exploited by malicious actors.
Regulatory Compliance Challenges:
- Compliance with cybersecurity regulations and standards can be challenging for some water and wastewater facilities. Failure to meet these requirements may expose them to increased risks.
Addressing these vulnerabilities requires a multi-faceted approach involving technology upgrades, employee training, robust cybersecurity policies, and collaboration with regulatory bodies and cybersecurity experts to enhance the overall resilience of the water and wastewater sector.
The risks in the water and wastewater industry are diverse and can have severe consequences for public safety, the environment, and the economy. Some key risks include:
Disruption of Operations:
- Cyberattacks can disrupt the normal functioning of water treatment and distribution systems, leading to service outages, water quality issues, and potential health hazards.
Physical Damage to Infrastructure:
- Malicious actors may attempt to manipulate control systems to cause physical damage to critical infrastructure, such as pumps, valves, and treatment facilities, leading to costly repairs and potential environmental damage.
Contamination of Water Supply:
- Unauthorized access to water treatment systems could result in the introduction of contaminants into the water supply, posing significant health risks to the population.
Data Manipulation and Falsification:
- Cyber attackers might manipulate data within the systems, leading to incorrect readings and mismanagement of water treatment processes. This could compromise the integrity of water quality monitoring and regulatory compliance.
- Operational disruptions, repair costs, and regulatory penalties resulting from a cybersecurity incident can lead to substantial financial losses for water and wastewater utilities.
Public Health Risks:
- Compromised water quality can pose immediate health risks to the public, leading to waterborne diseases and other health issues.
- Cybersecurity incidents can have environmental consequences, such as the release of untreated or improperly treated wastewater into rivers and ecosystems.
Loss of Public Trust:
- A cybersecurity breach in the water and wastewater sector can erode public trust in the safety and reliability of the water supply. Restoring confidence may take considerable time and effort.
- Non-compliance with cybersecurity regulations and standards may result in regulatory penalties, legal action, and increased scrutiny from regulatory bodies.
Supply Chain Disruptions:
- Cybersecurity incidents affecting vendors or suppliers in the water and wastewater sector can disrupt the supply chain, potentially leading to delays in equipment and service delivery.
Critical Infrastructure Dependencies:
- The water and wastewater industry is part of critical infrastructure, and disruptions can have cascading effects on other sectors, such as energy, transportation, and healthcare.
- Ransomware attacks can encrypt critical systems and demand payment for their release. Paying the ransom does not guarantee the recovery of systems and may encourage further attacks.
- Employees or contractors with malicious intent or unintentional errors can pose significant risks to cybersecurity within the industry.
Addressing these risks requires a comprehensive cybersecurity strategy, including regular risk assessments, employee training, the implementation of robust security measures, incident response planning, and collaboration with cybersecurity experts and regulatory agencies.
Here are some relevant standards and guidelines that may be applicable to the water and wastewater industry:
NIST Cybersecurity Framework (CSF):
- The National Institute of Standards and Technology (NIST) in the United States has developed the Cybersecurity Framework, which offers a set of best practices and standards that organizations can use to manage and improve their cybersecurity risk management processes.
