Water sector cybersecurity
Why the water business needs to be safe online Take a moment to think about this. You should be able to trust that the water that comes out of the tap is always clean and safe. A full network of treatment plants, pumps, and computerized systems makes that simple job possible. If someone gets into those systems, they could change the water quality data or even turn off the pumps.
The water company is at risk because its cybersecurity isn’t good enough. The truth is that the water industry is just as risky as banks and hospitals. Hackers are no longer just after money or personal information. They think that water is what keeps them alive. In just a few hours, a cyberattack on a city’s water supply could cause a lot of problems. This isn’t just a guess. We already have examples from real life that show how weak these systems can be.
Real-life scary things that happened
In 2021, someone tried to change the chemicals in a water treatment plant in Oldsmar, Florida. The good news is that the work was stopped before it could hurt anyone. But the fact that other people could get to it from far away showed how weak it was. This has happened in the past.
Ransomware attacks, phishing emails, and data breaches have all hurt small utilities all over the world. These things remind us that water is more than just something we drink. It is what life is built on. Hackers hurt both health and trust when they go after it. This means that cybersecurity in the water business is more than just a worry about computers. People start to need it.
The problems that water companies have that are different from other businesses Many water utilities are small and don’t have a lot of money, unlike big businesses. Some places don’t have any IT staff at all, while others only have a few. People who work with pipes and pumps might be good at that, but they might not know as much about firewalls and how to keep hackers out. Hackers take advantage of this hole.
A lot of people have old software, weak passwords, and operating systems that are no longer supported. The water sector often doesn’t have enough money to build strong defenses. That’s why we need to think outside the box to make water systems safe and cheap at the same time.
What types of systems are SCADA?
SCADA systems are computers that watch over and control the processes in a factory. Most water plants use SCADA systems. They work well, even though they were made when cyberattacks weren’t very common. They didn’t think about how safe they would be when they built them. Hackers can change how pumps, valves, and sensors work if they get in. What if the amount of chlorine in drinking water changed without anyone knowing? That’s why the water sector’s main goal right now is to make SCADA safer.
Ransomware:
A Quiet but Costly Threat Ransomware is a nightmare for all kinds of businesses, even those that sell water. When hackers attack, they lock up data and ask for money. Sometimes they say they will give it back. For a water company, downtime is more than just an annoyance. It can stop things from moving, make bills wrong, and make repairs take longer.
Some utilities have had to pay, but others have had to wait weeks to get back on their feet. Ransomware is easy and cheap for criminals to use. The victims have to pay a lot of money. This is one of the biggest things that could hurt the water business right now.
People making mistakes and not being able to connect with each other It’s not always the technology that’s the problem. People are the ones who cause problems most of the time. If you click on a dangerous link, use the same password again, or don’t update your software, hackers can get in.
People do things wrong a lot, which causes a lot of problems with cybersecurity. The answer is to keep an eye on your workers and train them. A lot of attacks can be stopped by using two-factor authentication, strong passwords, and keeping your software up to date. People are still an important part of the defense, even with the best firewall, because a careless click can still get through.
Water is a matter of national security. There are problems with water in more than one place. It’s about making the country safe. A big cyberattack on a lot of utilities at once could make a lot of people nervous. Consider how quickly some communities might run out of clean water.
This is a risk that governments are aware of. In the US, groups like CISA are already asking for stronger rules. A lot of countries are just as worried about the safety of their electrical systems as they are about the safety of their water. Now, it’s very important for the safety of the whole country to keep water safe.
Rules and the responsibility to follow them New rules and laws are coming out all the time. Utilities now have to follow stricter rules to keep their networks safe. Some people think these rules cost too much, but they are meant to keep people safe. They make sure that even small businesses think about more than just getting by. But rules alone won’t work. Checking everything off won’t stop an attack. The most important thing is to build a strong and safe culture that will last.
Getting help from people who know a lot about cybersecurity People who work with water don’t need to know a lot about how to keep their computers safe. That’s why it’s so important that we all work together. You can fill in the gaps by working with security companies, government agencies, or groups of volunteers. More and more people are hiring “white-hat hackers,” which is another name for hackers who do good things. Criminals look for weaknesses in systems before they do anything. These deals protect utilities and give experts a lot of information about important infrastructure.
Getting the right balance between risks and money Most of the time, budgets in the water business are very tight. Every dollar spent on cybersecurity is a dollar that could have been used to fix things or help customers. But not caring about cybersecurity is like leaving the door open for someone to come in. Stopping a cyberattack before it happens usually costs a lot less than fixing it after it happens.
Leaders need to see real-life examples of why they need to pay for cybersecurity. It’s a great way to keep bad things from happening to you.
The Internet of Things in Water Systems Everywhere you look, there are sensors, smart meters, and connected devices. They help find leaks, check the pressure, and cut costs. But hackers can also get into each device in a different way. That doesn’t mean you shouldn’t use IoT. This means we have to take good care of it. If smart devices are encrypted, get regular updates, and only a few people can use them, they can be useful and safe.
Teaching employees how to stay safe online Think of a fire drill. People would go crazy if they didn’t practice. Cybersecurity is the same way. Employees should know how to spot phishing emails, respond to alarms, and tell someone about problems. Some utilities even do “tabletop exercises,” which are practice cyberattacks. These practice sessions help people get ready for things and respond faster. Training is a big part of what makes you stronger.
Getting ready for possible threats that could happen in the future Just like technology, hackers are getting better at what they do. People who want to steal your information could use AI to make their phishing scams look more real. Quantum computers may even be able to break the encryption we use now in the future. That’s why the water industry needs to prepare for the risks of the future now. Utilities that are strong plan for the future, but those that are weak do not.
What do communities do?
A big part of cybersecurity is trusting each other. People in communities need water every day. People will be a lot more scared if you lie about a hack. People feel better about themselves when they can talk to each other. Some utilities try to get people to think about how bad the internet can be. This helps people understand why it’s so important for everyone to keep their computers safe.
The Road Ahead: Making Digital Resilience Stronger The future is clear. Keeping computers safe is one of the most important things the water sector can do. It won’t be cheap or easy. But doing nothing costs a lot more. You need to keep the water safe so that people are safe. Investing in people, technology, and partnerships can help keep water safe for a long time .
Final Thoughts
Water is life, and it’s more important than ever to keep it safe. Cyberattacks on the water business can make things harder, hurt people’s health, and make people in communities not trust each other. Hackers, mistakes made by people, and old technology are all real dangers. You need smart partnerships, well-trained workers, and technology that works to keep water systems safe.
You might think that spending a lot of money on cybersecurity is a lot, but it will cost you a lot more if you don’t do anything. Making SCADA systems safer, teaching people how to use them, and getting people in the community involved all help the system work better.
We know what we need to do next. Utilities can make sure that everyone has safe, reliable water more easily if they make cybersecurity a big part of how they manage water. Taking care of your life is like taking care of water. If you build strong defenses now, things won’t go wrong in the future.
