Through air-gapping, retailers can help separate payment and control systems for all these services. This model also serves businesses and large retailers such as Walmart, where many services-optometrist, automotive, tax preparation-are offered under a single roof. With an air-gapped network, you can keep your payment and control systems separated from the public and private networks that your company might otherwise use. Payment and Control Systems are Separated Since hackers have no chance to infiltrate your network, ransomware attacks and other cybercrimes are prevented. To hack into an air-gapped network, a cybercriminal would need in-person access, making remote hacking quite impossible. Setting up air-gapped backups of your data can greatly expedite any recovery efforts, in case you become a victim of any massive attacks. Even if cybercriminals were to get their hands on these digital assets, they probably won't be able to decipher or modify them. For example, by implementing encryption and hashing technologies along with role-based access controls, you can effectively achieve the same security controls as through a physical air gap. A logical air gap: As the name implies, this is the segregation of a network-connected digital asset by using a logical process.While they are in close physical proximity, they are still air-gapped away from each other because one is not plugged into the network. This usually entails having two servers on the same rack, for instance. Separated in the same environment: This air gap is achieved by simply disconnecting a device from a network.Anyone requiring access to data in this setup will need to cross physical security barriers to access it.

A physical air gap: This physically isolates all digital assets from any network-connected system.While they might have different variations, here are the three common concepts air-gapped networks are built upon.
