Understanding Air Gapped Security

Understanding Air Gapped Security

When it comes to security, Air Gapped is an increasingly popular concept. Air gapping refers to the physical or logical separation of two computer systems that aren’t connected via a network connection. This type of protection can be used in many different ways – from protecting internal corporate networks to keeping critical information secure during transmission over the internet. In this article, we’ll explore the concept of air gapping and look at how it helps improve security.

What is Air Gapping?

At its most basic level, air gapping involves separating two systems in a way that prevents them from being able to communicate with each other. This can be done either physically or logically. To physically separate two computers, there must be some form of physical barrier between them such as a wall. This is the most secure way to air gap two systems. Logically separating computers involves using software to limit communication and prevent data from being sent or received between two systems.

Benefits of Air Gapping

Air gapping offers a number of advantages, particularly in terms of security. By physically or logically separating two systems from each other, you can greatly reduce the risk of malicious threats spreading between them.

Reduced Risk of Attack:

By physically or logically separating two Systems, you reduce the risk of attack from both external and internal sources. This is because it’s much harder for malicious actors to breach one system without also breaching the other.

Improved Security:

Air gapping can also help improve security by making it more difficult for attackers to gain access to sensitive data. By limiting communication between two systems, you can limit the amount of data that can be sent or received. This makes it much harder for an attacker to gain access to sensitive information.

Increased Privacy and Anonymity:

Air gapping also provides increased privacy and anonymity by reducing the number of people who are able to access a system. This is especially important for organizations that need to keep their data private, such as banks and government agencies.

Improved Reliability:

Air gapping can also improve system reliability as it limits the number of people who are able to access a system. This reduces the risk of any malicious actors being able to disrupt the system or gain unauthorized access.

Increased Efficiency:

By limiting communication between two systems, air gapping can increase efficiency by reducing congestion on networks and improving the speed of data transmission. Additionally, air gapping can reduce costs by reducing the amount of hardware needed to access a system.

Improved Accessibility:

Finally, air gapping can improve accessibility by making it easier for users to access different systems from remote locations or devices. This is especially useful for organizations that need to provide remote access to their networks.

Step-by-Step Guide on How To Get Started With Air Gapping

If you’re interested in implementing air gapping, here’s a step-by-step guide on how to get started:

Identify the systems that need to be air gapped:

Before you can begin air gapping, you’ll need to identify the two systems that will be separated. These could be two internal networks or two external systems.

Choose a physical or logical separation:

Once you have identified the two systems, you’ll need to decide whether to use physical or logical separation. Depending on your needs, one may be more suitable than the other.

Implement air gapping measures:

Once you’ve chosen a type of air gapping, you can begin to implement the necessary measures. This could involve setting up a firewall or other security measures.

Monitor and maintain:

Finally, you’ll need to monitor and maintain your air gapped systems to make sure they stay secure. This could include auditing the systems regularly and updating security protocols when necessary.

Best Practices for Utilizing Air Gapping

When it comes to air gapping, there are several best practices that you should follow. Here are some of the most important ones:

Ensure all systems are properly isolated:

To ensure your air gap is secure, it’s essential that all systems are completely isolated from one another. This means making sure there are no physical or logical connections between the two systems.

Keep all air gapped systems updated:

It’s important to regularly update your air gapped systems to ensure they remain secure. This includes updating both operating systems and other applications on the system.

Use multiple layers of security:

To further improve security, it’s a good idea to use multiple layers of security. This could include firewalls, encryption, access control, and other measures.

Monitor traffic and activity:

Regularly monitoring the traffic and activity on your air gapped systems can help you identify any suspicious behavior. This can help you spot potential threats before they become a problem.

Train employees:

It’s also important to train employees on how to use air gapped systems properly. This can help them understand the importance of security and how to keep their data safe.

Implement authentication procedures:

To ensure only authorized users are accessing your air gapped systems, it’s essential to implement authentication procedures. This could include using strong passwords or two-factor authentication.

Keep air gapped systems off public networks:

To ensure your air gap remains secure, it’s important to keep the systems off of public networks. This will prevent any malicious actors from gaining access to the system.

Regularly audit for vulnerabilities:

Finally, it’s important to regularly audit your air gapped systems for vulnerabilities. This can help you identify and address any potential issues before they become a problem.


Air gapping is a great way to improve the security of your systems. By following these best practices, you can ensure that your air gap remains secure and your data stays safe. Implementing an air gap can also improve the reliability, efficiency, privacy, and accessibility of your system. With a little bit of planning and effort, you can reap the benefits of air gapping.


What is air gapping?

Air gapping is the process of physically or logically separating two systems, networks, or devices from one another. This can help improve security and privacy by limiting communication between the two systems.

Why should I use an air gap?

Using an air gap helps to improve security, increase privacy and anonymity, improve reliability, increase efficiency, and improve accessibility.

How do I implement an air gap?

Implementing an air gap involves identifying the two systems that need to be separated, selecting a physical or logical separation, implementing necessary security measures, monitoring and maintaining the system, and following best practices for air gapping.

What are the best practices for air gapping?

Some of the best practices for air gapping include ensuring all systems are properly isolated, keeping all air gapped systems updated, using multiple layers of security, monitoring traffic and activity, training employees on how to use the system properly, implementing authentication procedures, keeping air gapped systems off public networks, and regularly auditing for vulnerabilities.

Are there any risks associated with air gapping?

Yes, there are some security risks associated with air gapping. For example, if a malicious actor is able to access the system through physical or logical means, they may be able to bypass the air gap and gain access to sensitive information. It’s important to monitor and audit your air gapped systems regularly to ensure they remain secure.
