Collective defense: A different way to approach healthcare cybersecurity For some time, healthcare organizations have been defending against cyberattacks on their own while malicious actors have been organizing into increasingly sophisticated networks of attackers. A better way to combat cybersecurity threats is by sharing and correlating events across organizations, both within the healthcare sector and across industry sectors, contend experts at IronNet Cybersecurity. General (Retired) Keith Alexander, co-CEO of IronNet Cybersecurity, former NSA director and former commander of the U.S. CyberCommand, explored this notion in a recent HIMSS20 Digital session, "Cybersecurity's Tectonic Shift: A Call for Collaboration." Along with IronNet Cybersecurity Chief Marketing Officer Russ Cobb, Alexander described the people, processes and technologies that are making collective defense" a reality. How do you protect what you cannot see? "At the NSA and at CyberCommand, we had the mission of protecting the nation," Alexander said. "The problem is you are trying to protect something that you cannot see. It's analogous to running an air defense without any air-defense data. Tracking airplanes requires you to create this picture so that air traffic controllers can see airplanes and make sure they don't bump into each other and direct air traffic. So it's very useful." In cybersecurity, there is no picture. "The government today is focused on incident response, which means the system has been hacked, we've lost some data, and it's too late," Alexander said. So the first part, if we want to defend the nation, we've got to be able to see it. And if you think about how the adversary operates, the adversary has this team that can hide against all the current defenses that we have. This is not one person sitting on a bed. These are well- trained teams. They are well-rehearsed, well-trained, they know what their plan is, they work their way through it, and they work it together." Now look at how organizations defend against bad actors. A mid-sized bank might have 10 people on the problem defending their organization. "They see what's going on in that company, and they try to protect against it," Alexander explained. "And they use signature-based systems. The adversary knows what they are using and uses that to get by, whether it is phishing or some other type to get into the network. Once the bank finds out they have been hacked, they look at it from a liability and reputational angle and then they share it after that. That's way too late." Creating a "picture" of cybersecurity Alexander said what needs to be done is to create an air traffic control-like picture of cybersecurity. "The way to do that is to now create the event logic that allows you to see as things are occurring and an expert system that allows you to understand it," he said. "There is a lot of traffic out there, a lot of volume. So we've got to change the way we think about cyber from taking a bunch of boxes and trying to knit them together to collective defense." The government is needed to help defend the country and organizations, but the government cannot see the country and organizations when it comes to cybersecurity, Alexander said. "That in itself is broken," he remarked. "That means if we had radar, we cannot tell the air traffic controllers what we see. So this is a transformation that has to occur in our country and others to really move cybersecurity to where it needs to be. Collective defense means we need to work together better than the offense, sharing data and collaborating together
