AIR GAPPED COMPUTER BLUETOOTH
For example, one might refer to a cell phone, laptop or tablet with Bluetooth connectivity turned off as “air gapped.” However, true air gapped devices are not just disconnected. The term “air gapping” has been used casually to describe any system without a Wi-Fi connection. However, some users opt for logical air gapping because it is easier to grant access and transfer data. Physical separation creates the most secure air gapped network. Is Physical or Logical Air Gapping More Secure? In these hybrid models, computers are physically isolated from one another, but can be connected to a network if needed. Some air gapped systems are a hybrid model.
AIR GAPPED COMPUTER SOFTWARE
Adshead writes that a logical or conceptual air gap is created through “a protection in software.” This software protection “isolates secondary site locations from production and primary backup environments. Antony Adshead explains in an article for Computer Weekly. In a logical or conceptual air gap, software is used to silo devices. Data transmitted between devices in a physical air gapped system can only be shared manually by authorized users.
What Exactly are Air Gaps?Īir gaps are physical or conceptual separations between devices that prevent unauthorized access to data at rest. In this post, we consider data transfer challenges in an air-gapped environment. In some cases, this means that commercial software and hardware cannot be used.Īs such, air-gapping presents several challenges regarding moving data within an air-gap environment and moving data out of that environment. Many air-gapped systems are housed in high-security facilities like SCIFs and SAPFs. Such environments lack any of the hardware that would make internet connectivity and virtual access possible. To protect against malware and other attempts to steal data, only people who have physical access to air-gapped systems can utilize them. All these security measures mean that data housed in air gapped systems can be somewhat difficult for authorized users to access.Īir-gapped computers are physically isolated. One would need to be in the same physical space to breach air gapped computers. As we note in a previous post, an air gapped computer or air-gapped network is one that has been siloed from others.Īir-gapping creates a highly secure environment in which data is well-protected. Moving data in an air-gapped network can be difficult due to the intensive protocols required to protect sensitive data during transit.
