I think it's a fun thought exercise and a real world situation. Best defense would be not to allow USB storage media on air gapped systems.
I can assure you this is for 100% legal purposes. So, if I set up my own time server that responds as maybe that would be sufficient.Īssume I can get a computer on this isolated network, but once on it, it could never connect back out due to the air-gap. How would one emulate being a time server? I can't access the machines to change the time server they point at, I know that they will automatically pick up if allowed to connect outward. Air gapping is crucial as a standalone strategy, but it’s also very smart to apply it to the 3-2-1 protection rule. Essentially, that air-gapped system is the super-strength backup that gives your network a Teflon blanket should any other method fail. I'm familiar with DNS, and have done wireshark captures before. Adding an air gap to this essential backup rule is another layer of protection on top of that.

They are also called an offline strategy. This protects it from almost any type of cybersecurity threat. An air-gapped backup is a copy of your data that is kept offline so that it cannot be accessed by a hacker. You could in theory speed up the occurrence of something, by repeatedly changing the time on the network. Air gap means offline and not connected to your network or the Internet. If the machines do something at a certain predefined system time, and if sent them a packet stating the current time was such time to make them do work, that would be pretty cool. Since those devices are air-gapped, they don't see that time server and default to a system time kept on a RTC battery. Air-gapping effectively segments networks in a way that ensures if hackers exploit vulnerable applications in one network, they cannot access vulnerabilities in any air-gapped networks. I happen to know that all of the devices on the network are configured to set the time based on . Air-gapped networks, also known as parallel networks, are networks that are physically separate from one another. I'm working with an industrial network that is air-gapped. However, researchers have developed multiple communication paths that circumvent computers on air gap networks. Attacker has been able to infect one of the laptops inside of an air gapped network. I also would find use for this for other purposes. Hence, data can only pass via removable media such as USB. I am noting a potential vector for research and happen to have the ability to prove out some credible suggestions in an isolated environment. GAPS is a huge undertaking, tinged with the irony that the very thing that causes so many problems on physical air-gapped networks is the way computers are connected to one another via global internet protocols famously a DARPA invention. A true air-gapped network is physically isolated from all internet-enabled devices. Not only will our technology protect you from long-term reliability issues like bit rot and file corruption, but you’ll also stay safe from the hardest to detect cyber attacks including Insider Threats, Remote Access Trojans, and Ransomware Encryption and Exfiltration.This is not a "Help me to hack" post. That’s why we built BrickStor SP using DoD principles for security and data protection. To truly protect your most critical data at scale, an automated air gap architecture is the most secure and scalable solution.Įvery organization has the right to protect their data as if it were a national secret.

Tapes and portable disks are prone to theft and data loss, and backup systems with discretionary access controls are easily circumvented by rogue insiders or advanced persistent threats. But with the volume of new data growing exponentially, it’s impractical to implement a disconnected solution which is both secure and efficient. As threats to organizational data continue to evolve and become more sophisticated, the only way to protect your most critical data is to remove it from the network completely.
