ICS TRIPLEX 1433/09232486825 Void systems are computers or networks that typically contain highly sensitive or business-critical data
At a time when combat technology and information technology (IT) were two different things, air gaps used to be the gold standard for protecting combat technology (OT) environments.
In the past, many traditional electronic devices, such as thermostats and home appliances, adopted air gaps due to their inherent limitations rather than for safety reasons. However, with the widespread spread of wireless components, OT is no longer air-gap because the technology is connected to the Internet.

Air gap safety
To protect critical data, additional safety precautions should be taken to support air gaps. This includes disabling USB ports and using Faraday cages to block wireless transmissions and prevent electromagnetic (EM) leaks.
Today, true isolation also requires the elimination of electromagnetic radiation leaks. This includes blocking FM and cellular frequency signals, blocking thermal and near-field communication (NFC) channels and LED light pulses.
Air gap
ICS TRIPLEX 1433/09232486825 Although the air gap provides a high level of security, it still has the potential to break the air gap computer. While the concept of physical isolation is simple, it is increasingly difficult to enforce.

Air gap attacks are a growing cyber threat, especially for air gap networks that are isolated from the Internet. Security experts have found that cutting-edge acoustic channels that employ ultrasonic, inaudible sound waves can be used as vectors to attack smartphones capable of picking up higher frequencies. Data can also be siphoned via radio signals even if Bluetooth is disabled. Is that why, in many high-security environments, mobile phones are not allowed within range of the most critical systems
