Helps protect networks from cyber attacks and other intrusive strikes from hackers, malware, and other ruinous software. There are other positives to utilizing an air gap strategy, including the following: Reading up to this point, you have probably deduced that air gapping can be extremely beneficial for protecting your data. Air gapping is crucial as a standalone strategy, but it’s also very smart to apply it to the 3-2-1 protection rule. Adding an air gap to this essential backup rule is another layer of protection on top of that.Įssentially, that air-gapped system is the super-strength backup that gives your network a Teflon blanket should any other method fail. It’s something anyone with important and sensitive data should always think about doing. The 3-2-1 rule is a primary strategy should you need to implement a disaster recovery plan. Keep at least one of those copies in a different physical space, somewhere that is offsite from where the main network lives. Utilize at least two different types of media to store data (such as cloud storage or on a disk). The basic concept breaks down like this:Ĭlone at least three different copies of your most critical and important data. The 3-2-1 rule is a well-known strategy for protecting data systems in the cybersecurity industry. Air gaps are built into cloud storage by using access controls (like additional log-in credentials, PINs, etc.) or even basing the storage in a location that is difficult for hackers to access. These fall into the logical air gap family because the security measures are digital.
Air Gap CloudsĬompanies that host and provide cloud storage sometimes utilize air gaps to protect data. Implementing protective measures with things like encryption, access control, cloud security, firewalls, and other security solutions (like Veritas NetBackup) are examples of a logical air gap.

Instead of using physical devices to protect data, a logical air gap employs software programs to initiate the gap. These physical items are the safe hosts to system information that is inaccessible to the rest of the system unless that information is provided to the other devices. The literal separation of air-gapped computers from other networks or devices.
While the concept of air gapping is the same, there are a couple of different ways to apply the technique. That way, there is zero possibility of the computer being accessed, which, in theory, serves as an uncompromised and safe method for protecting your data. How An Air Gap WorksĪir gaps work by routinely supplying data to the isolated system through storage systems such as USBs, firewires, or other types of removable media devices that transfer data without online access. Also known as an air wall, air gapping utilizes isolation of the system’s network, keeping it separate from other connected devices and preventing online access to the air gapped computer. The “air” in the technique’s title literally describes the concept of keeping a barrier between data and online access to it.

What an Air Gap DoesĪir gapping involves keeping an offline copy of important information to prevent any chances of data being compromised. Getting more in-depth about air gap backups means understanding the ‘what’ and the ‘how’ of the strategy. When you use an air gap backup, you’ve already built a fortified layer of network protection by ensuring it always exists.
When a network is devastated by major events like cyber-attacks, system failures, or even natural disasters, people and businesses are then faced with the daunting task of initiating disaster recovery procedures to regain what has been lost. If you’ve never heard of an air gap, this is the perfect time to learn what it is and what it can do for your information systems. If you have or have ever had an air gapped computer, then you already have an idea of how this strategy helps keep data safe from hackers. One of those strategies that can be utilized is the air gap technique.Īn air gapped network is a protected network. There are many types of strategies for protecting and recovering sensitive data in information systems in the cybersecurity environment.
