![]() ![]() Have a strong monitoring policy and tools in place that can identify users who are misusing devices, overstepping data access, and sharing privileges.It’s also a great idea to limit access to air-gapped devices to only upper management, power users, and others when absolutely necessary. Ask yourself where the network hardware should be placed, who can use it, and how. Develop strict policies over the implementation of air-gapped networks.While air-gapped networks are isolated from external connections, we also want to make sure the devices inside those networks remain physically inaccessible as well otherwise, it would defeat the purpose of having an air-gapped network. ![]() Keep a watch on removable media and devices such as laptops, modems, and VPNs.Here are a few steps you should take to make your air-gapped networks as secure as possible. While air-gapped networks seem to be the epitome of network security, they're not infallible. But the problem with legacy software is that it can only run on outdated and vulnerable devices (or the software is vulnerable itself). ![]() In some cases, companies might need to operate legacy software. 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.
