One of the simplest ways of keeping a computer system secure is by using an air gap — that is, never actually connecting the system to the network. This can …read more Continue reading Photoresistors Provide Air Gap Data Transfer, Slowly
Say I have this computer that I bought and followed a manual to physically remove all communicating modules on its motherboard, including Wi-Fi adapter, Bluetooth adapter, etc. Assuming physical security i.e. no one can see my screen throu… Continue reading Does physical removal of all communicating modules on the motherboard ensure complete safety, assuming physical safety?
How safe is it to transfer data using a USB drive between my air gaped pc and my regular pc? What things can be done to improve the safety of this?
I have developed an Excel spreadsheet to compare lists of SHA-512 hashes from two separate drives. One drive is the source data drive on a Windows machine. The other is a backup of that drive, connected to a Linux machine. I obtain the has… Continue reading Hash-Based Technique to Detect Ransomware Corruption on the Fly?
Good news, everyone! Security researcher [Mordechai Guri] has given us yet another reason to look askance at our computers and wonder who might be sniffing in our private doings. This …read more Continue reading Ethernet Cable Turned into Antenna to Exploit Air-Gapped Computers
I’m a developer in the cryptocurrency space, dealing with private keys (PK) linked to wallets containing money and I’m interested to see if this system I plan to use is secure or if I’m missing something. I define secure as the chance of t… Continue reading Is this hypothetical system dealing with sensitive keys secure? [closed]
I’m trying to take information that’s on Computer A, write it onto some form of persistent storage, and copy that information onto Computer B. Both will be running a relatively recent version of Windows 10. The computers may be hundreds of… Continue reading How do I securely transfer information between airgapped systems?
What would be a way to transfer files in one direction from internet-facing computerA => air-gapped computerB to protect the files on computerB from unauthorised disclosure, short of using an expensive data-diode?
Requirements
The data… Continue reading Unidirectional continuous data transfer to an air-gapped computer
I’ve been reading up on malware that can bridge air gaps between computers, like GSMem, Funtenna, etc. In the papers and articles I’ve been reading, the researchers mostly talking about getting files and data out of air-gapped computers us… Continue reading Can attackers send commands to/control infected air-gapped computers?
Organizations find themselves in a quandary these days when it comes to whether they should deploy an air-gap strategy—a strategy in which secondary backup data is saved in an offsite and offline location, physically separating it from primary product… Continue reading Using SaaS Backup and Recovery to Protect Your Data With a Virtual Air Gap
