Understanding Air Gapped Systems: A Closer Look at Cybersecurity

In the digital era, where cyber threats are omnipresent, securing sensitive data is of paramount importance. One security measure that’s increasingly gaining attention is the concept of an “Air Gapped System.” But what exactly does this term mean? And why is it crucial in today’s cybersecurity landscape?

What is an Air Gapped System?

An air-gapped system refers to a computer or network that is physically segregated from other computers or networks. This means that it cannot connect wirelessly or physically to other devices, acting as a bulwark against potential cyber attacks. The idea behind an air gapped system is to create a ‘gap’ of air between the system and others to safeguard critical Data.

The Importance of Air Gapped Systems

Air gapped systems play a pivotal role in the realm of cybersecurity. They offer an additional layer of security for organizations that handle sensitive information by isolating their data from unsecured networks. This isolation prevents unauthorized access, thereby protecting the system from malware, ransomware, keyloggers, and other malicious attacks.

Types Of Air Gapped System

1. Fully Air Gapped System:

This is the most secure type of air gapped system. It involves completely isolating a computer or network from all other devices, including even those on the same local area network (LAN).

2. Partially Air Gapped System:

A partially air-gapped system is one that has limited communication with other systems but still allows some level of access to external networks.

3. Pre-Internet Systems:

These are air-gapped systems that existed before the internet and are usually isolated from any external connections.

Advantages & Disadvantages Of Air Gapped Systems


1. Improved Security:

Air gapped systems provide an additional layer of security against external threats.

2. Reduced Risk Of Data Loss:

Isolating the system from other networks reduces the risk of data loss due to malicious attacks or virus infections.

3. Greater Resilience To Cyberattacks:

Air gapped systems are better-equipped to withstand cyberattacks because they are not connected to other networks and thus can’t be infected by malware.

4. Increased Privacy Protection:

Air gapped systems protect sensitive data from being accessed by unauthorized parties, ensuring greater privacy protection.

5. Local Network Control & Management:

By keeping all components inside a local network, air gapped systems give organizations full control over their system, allowing them to manage and configure it according to their needs.


1. Difficult To Maintain:

Maintaining an air gapped system can be difficult, as there’s no one-size-fits-all solution for maintaining the isolation of the system.

2. Expensive:

Due to its complexity, air gapped systems can be expensive to set up and maintain, making them impractical for smaller organizations with limited budgets.

3. Vulnerable To Physical Attacks:

Air gapped systems are vulnerable to physical attacks such as theft or tampering if not properly secured.

4. Limited Scalability:

Air gapped systems are difficult to scale due to their isolated nature, making them impractical for organizations that need to rapidly expand their systems.

5. Limited Resources:

Air gapped systems typically have limited resources, as they are not connected to external networks or devices. This can make it difficult to access certain types of data or software.

6. Manual Data Transfer Is Required:

Since air gapped systems are separated from outside networks, manual data transfer is required in order to transfer information between these systems and external sources.

7. Not Easily Accessible:

Due to the physical isolation of air gapped systems, they are not easily accessible, making them difficult to troubleshoot and maintain remotely.

8. Prone To Human Error:

Due to the complexity of air gapped systems, they are prone to human error. This can lead to security breaches or data loss if the system is not properly configured or maintained.

Best Practices for Air Gapped Systems

1. Establish Physical Security Protocols:

It is important to establish physical security protocols to protect air gapped systems from unauthorized access or tampering. This includes measures such as setting up locked doors, alarms, and CCTV cameras.

2. Restrict Access To Critical Components:

Restrict access to critical components of the system by setting up authentication protocols and requiring users to have authorized credentials in order to gain access.

3. Implement Data Protection & Encryption Measures:

Ensure that data stored on air gapped systems are properly protected with encryption technologies and other security measures such as firewalls and antivirus software.

4. Regularly Monitor The System For Vulnerabilities:

Regularly monitor the system for any vulnerabilities or suspicious activity that could indicate a potential breach. This can help identify and address problems before they become more serious.

5. Limit Communications With External Networks:

Limit communications with external networks to prevent data from being accessed or compromised by malicious actors.

6. Regularly Update Software & Firmware:

It is important to regularly update software and firmware on air gapped systems in order to ensure that they are up-to-date and secure against the latest threats.

7. Establish Security Policies & Procedures:

Establishing security policies and procedures for air gapped systems ensures that employees are aware of the rules surrounding such systems and how to properly use them.

8. Train Employees On Security Protocols:

Provide employees with the necessary training so they understand security protocols and how to properly use air gapped systems. This helps ensure that users are not introducing any potential vulnerabilities into the system.


Air Gapped systems are the perfect solution for organizations that need to protect sensitive data and information from external threats. Although air gapped systems have some drawbacks, such as being difficult to maintain and expensive to setup, they offer an extra layer of security which makes them worth considering. Following the best practices outlined above can help ensure that air gapped systems remain secure and reliable.


1.What is an air-gapped system?

An air-gapped system is a computer that is isolated from external networks and the internet. This makes it more secure than connected systems, as there is no risk of malicious actors or viruses being able to access the data stored on the system.

2. What are the advantages of using an air gapped system?

The main benefit to using an air gapped system is improved security against external threats, as well as greater resilience to cyberattacks. Additionally, it offers increased privacy protection and full control over the local network for better management and configuration.

3. What are some of the downsides to using an air gapped system?

The main downside to using an air gapped system is that it can be difficult to maintain and expensive to setup. Additionally, the system is vulnerable to physical attacks, has limited scalability, and data transfer between air gapped systems and external sources must be done manually.

4. What are some best practices for using an air gapped system?

Some of the best practices for using an air gapped system include establishing physical security protocols, restricting access to critical components, implementing data protection and encryption measures, regularly monitoring the system for vulnerabilities, limiting communications with external networks, regularly updating software and firmware, establishing security policies and procedures, and training employees on security protocols.

5. Is an air gapped system worth considering?

Yes, it is worth considering if your organization needs to protect sensitive data and information from external threats. Although there are some drawbacks to using such a system, the extra layer of security it offers makes it a viable option for those looking for additional protection.
