Although, from the definition of Air gapping, it might seem that an air-gapped system is safe from external attacks. However, there are instances where a hacker can target a disconnected computer. Below are a few threats to air-gapped computer systems.

The continuous evolution of the world has resulted in man’s preference for technology as the default mode of automating processes. This, perhaps, accounts for why man is regarded as a technological being, given that most assets and information in our 21st-century world are stored in a digital format and secured with computer systems in what is known as air-gapped computer systems. These air-gapped computer systems that have been disconnected from other networks offer minimal access and a lot of security from unauthorized access.

Therefore, Air-gapped networks are only as effective as your networking and security policies are willing and able to make them. They can be nearly foolproof if strict network policies are implemented and constantly overseen by network administrators.

Likewise, the Stuxnet worm case from 2010 is a strong case of how network hardware can cause damage as that particular strain of malware spread to Iranian and nuclear plants in the USB drives.

Air-gapping has proven quite effective over time in securing computer systems. However, cybercriminals have found ways to attack air-gapped computers. Sentinel.one affirms the most notorious example of the Stuxnet attack designed to target Iran’s nuclear program. Although it was discovered in 2010, it is thought to have been in development since 2005.

Air-gapped computer systems are used for systems or networks that require extra security fortifications. Such systems generally include classified military networks, financial networks such as payment networks that process retailers’ credit and debit card transactions, and industrial control systems that operate critical infrastructure such as nuclear power plants.

At the time of discovery, the Stuxnet worm was a 500kb program that infected the software of over 14 individual sites in Iran. It targeted Microsoft Windows machines and spread on its own through USB drives plugged into the air-gapped machines on the network. The result was Iran losing almost one-fifth of its nuclear centrifuges.

Rubrik defines Air Gapping as a security countermeasure that creates an impenetrable barrier between a digital asset and malicious actors. Malicious actors can be hackers, viruses, natural disasters, and any force threatening a digital asset.

In conclusion, it is important to note that our 21st-century world continues to battle data privacy concerns. Such concerns are typically exemplified by countermeasures deployed to safeguard data and digital assets and protect them from unauthorized access. One of such countermeasures that relate specifically to computers is Air gapping. Air gapping could potentially be adequate, but users and employers must take proper security measures to forestall incidents of computer system breaches.

As much as the benefits and potentials of Air gapping are intriguing, there are also setbacks to air gapping, and the major ones are outlined below:

Air gapping used to be impossible to breach but now is no longer the case; here are some strategies organizations can use to ensure their air-gapped systems are never connected to the internet. Exposure can open up a system to compromise, and these systems most likely hold critical information, which can be disastrous.

Although the high level of security air gapping has created, cybercriminals use modern techniques and tools to extract data from computer systems. Some of them include:
