For example, through encryption and hashing, coupled with role-based access controls, it is possible to achieve the same security outcomes that are available through a physical air gap. Logical air gap-A logical air gap refers to the segregation and protection of a network-connected digital asset by means of logical processes. One could have two servers on the same rack, for instance, but still air-gapped away from each other because one is not plugged into the network. Segregated in the same environment-An air gap can be achieved by simply disconnecting a device from a network. If anyone wants to get data from it or put data onto it, they must physically go to it, a process that usually involves going through physical security barriers. A digital asset in a total physical air gap has no network connections. The total physical air gap-This is the salt mine type, which involves locking digital assets in a completely isolated physical environment, separated from any network-connected systems. At a high level, three main types are the most common: There are many variations on the air gap concept. However, air gap backups provide a critical layer of data protection against all forms of data loss, and can help businesses recover from a wide range of disaster recovery situations. Implementing air gap backups can be a challenge for businesses, as it requires a high level of security and planning. There are several things to keep in mind when implementing air gapped backups for business:Īir gap backups should be stored in a secure location that is not accessible to unauthorized personnel.Īir gap backups should be updated regularly, typically daily or weekly.Īir gap backups should be tested periodically to ensure that they can be used to restore data in the event of a disaster.Īir gap backups should be encrypted to protect sensitive data from being accessed by unauthorized personnel.

Air gap backups can be used to restore data in the event of a disaster, such as a fire or flood, or if data is lost or corrupted due to a software glitch, hardware failure or ransomware attack. Businesses of all sizes can benefit from air gap backups, which protect data from being destroyed, accessed, or manipulated in the event of a network intrusion or system failure.Īir gap backups are typically stored in a secure location off-site from the business, such as in a secure server facility.
To understand why air gaps are still important, it’s worth taking a moment to define the concept and explore what’s working well with them and what isn’t.Īs the world moves increasingly online, air gap backups provide a last line of defense against data loss. Some organizations absolutely require them, but the practical realities of implementing and sustaining an air gap have grown quite a bit more difficult over the last two decades. It’s easy to make fun of Hollywood and its excesses, but the film did reflect the predominant view at the time that the best security came from putting air between a system and anyone or anything trying to reach it. If you wanted to use it, you had to be in that highly secured room. It was a freestanding computer that was not attached to any sort of network. Couldn’t he just hack the machine? No, because that CIA system was air-gapped.
Remember when Tom Cruise hung upside down from the ceiling in Mission Impossible and tried to steal data from a computer housed in a top-secret vault at CIA headquarters? From the perspective of today, we might wonder why all the crawling through the air ducts and risking his neck was necessary.
