As a security professional, I probably take security more seriously than most. But when we start talking about the Internet of Things (IoT), the science fiction buff in me comes to the forefront a little bit. While we don’t want any kind of attacks to happen to our organizations, it can be a little fun to imagine the crazy ways hackers can use mundane appliances to hack into a network.
For example, earlier this year, a North American casino was hacked through a smart fish tank. Since the equipment in the tank was connected to the Internet, attackers were able to use that as their vector for network access. Fortunately, the breach was discovered quickly afterward—and you never want to hear about security breaches like this, but it certainly does make for a unique story.
That highlights the risks that are out there today. If you’re connected to the Internet, you are vulnerable to attacks. With IoT and the proliferation of smart devices, we’re starting to see some creativity from hackers that is not necessarily being counteracted with the appropriate level of security controls. That fancy fish tank certainly didn’t have the appropriate level of security controls. Having “regular” devices connect to the Internet can bring flexibility and manageability, but it also opens up more vulnerabilities.
That risk is something that everybody needs to understand. Basically, like any good risk owner, you need to think about what device you have, how it’s connecting, where it’s connecting to, and whether or not that connection has a level of security that meets your policy and control expectations. Honestly, what I’ve seen is that because of the easy and seamless connectivity of these smart devices, a lot of organizations are not thinking about necessary security measures. They aren’t quite seeing that a fish tank or a biomedical device or even an HVAC system can be just as vulnerable to attack as a server or application.
So how do you keep your network and data safe and still take advantage of the benefits of the IoT? Employ the same techniques I spoke of last week: protect, detect, and react. Assess, document, and validate risks. Make sure that you have a complete and total information security risk management or risk governance program. Apply these techniques and programs to every single device on your network, no matter how low-level it may seem. Something as normal as a thermostat or refrigerator could be a gateway for a hacker.
Our experts can help you assess your environment for risks and vulnerable points in your network, and help you put together a comprehensive security program that doesn’t leave out anything—even your lobby fish tank or break room fridge.
