How Air-Gapped Computers Can Help Protect Your Data
IoT devices, or devices that can connect to the Internet and transmit data, have rapidly become an essential part of our everyday lives. Nowadays, everything from our phones and computers to our refrigerators, thermostats, and doorbells are connected to the Internet, leaving a variety of security vulnerabilities within our networks.
A unique solution for businesses and organizations hoping to combat the risk of unsecured networks is an air–gapped computer. Commonly used in high-security environments such as military or financial networks, an air-gapped computer is completely isolated from unsecured networks, both physically and technically.
Air–gapped computers are not directly connected to the Internet or any other system that is connected to the Internet. According to The SSL Store, “A true air-gapped computer is also physically isolated, meaning data can only be passed to it physically (via USB, removable media or a firewire with another machine).”
Air-gapped computers provide an added layer of security as they are much more difficult to breach than the average device that is connected to the Internet. To breach an air-gapped computer, the attacker must generally be within a close physical proximity to the computer and insert a malicious USB device such as a hard drive. Social engineering is the most common way that air-gapped computers are breached, however there are other more complicated potential ways of attacking an air-gapped computer.
Researchers have recently found a new, rare form of malware called Ramsay being spread across air-gapped networks. There are currently three different variants of the malware but according to researchers, it presently appears to be in its developmental stage. Electromagnetic or acoustic channels could also be used to target air-gapped computers, but these kinds of attacks are about as likely as someone rappelling from the ceiling like Tom Cruise in Mission Impossible to infiltrate the isolated computer (highly unlikely, but it’s possible!)
For businesses and organizations seeking to secure their information as much as possible and reduce the risks of unsecured networks, air-gapped computers may provide peace of mind and an additional layer of defense against cybercriminals.
