We live in a world where we are surrounded by sensors. Thermostats, speedometers, infrared, and a vast array of other types of sensors help to inform us about the environment around us and, in many cases, warn us of potential danger. A modern cell phone has more than half a dozen sensors measuring things like facial characteristics or fingerprints, barometric pressure, direction, proximity, tilt, and ambient light. The automotive world has been dramatically changed by sensor technology, enabling many new safety systems to be developed. Systems like blind spot detection, adaptive cruise control, lane detection, collision mitigation braking improve safety and provide a more safe and pleasurable driving experience. It's now possible for those who never learned to parallel park to do it on the first try!
What does this have to do with network security? A LOT! Chief Information Security Officer (CISO) 2019 priorities are identified in this Forbes article, and the top of the list (spoiler al
ert) is to "Gain threat visibility across all platforms." That visibility will be provided by sensors. You probably already have software sensors that monitor network traffic for anomalies like firewall penetration, changes in data patterns, or new devices on the network. Even with all of the sensors deployed to monitor network traffic, there is a huge blind spot in many IT systems: Your physical network infrastructure.
Without a sensor to monitor the health of your physical infrastructure, there is no good way to detect tampering or tapping at the physical layer. Also, as the higher network layers are made more secure, it naturally drives more effort by bad actors into getting to the physical layer of your network. In fact, number five on the CISO priority list is to “Address risks from inside the firewall”- risks from employees and contractors who have access to your facilities. From the article: “CISOs increasingly are investing in systems that can spot those kind of red flags...” Without a sensor, how would you know that someone has targeted your infrastructure? How would you know that you aren't leaking sensitive data right now?
The Network Integrity Systems line of sensors is specifically designed to monitor your physical fiber infrastructure for any kind of tampering, tapping, or inadvertent changes. We protect the most sensitive networks in the world, and we have solutions for indoor networks such as data centers, as well as campus and long-haul networks.
