The Advantages and Limitations of Air Gapped Systems

In the world of cybersecurity, air gapped systems are often considered to be one of the most secure ways to protect sensitive information. This isolation makes it nearly impossible for hackers or malware to gain access to the system. In this article, we will explore both the advantages and limitations of air gapped systems and provide insights into their best use cases.

What is Air Gapped System?

An air gapped system is a computer or network that is completely isolated from unsecured networks and the internet. This means that all communication with the outside world must take place over a secure channel such as a physical cable connection, Bluetooth, or even an optical link. By physically isolating systems from the internet, it makes it nearly impossible for cyber attackers to gain access to the systems and any sensitive data contained within.

Types of Air Gapped Systems

Air gapped systems come in two main varieties –

1. Hard Air Gapped Systems

Hard air gapped systems are completely isolated from the outside world. All communication with them must be done through physical cable connections, Bluetooth, or optical links.

2. Soft Air Gapped Systems

Soft air gapped systems are slightly less secure than hard air gapped systems. This allows for the transfer of data between two machines without having to directly connect them to a network.

Advantages of Air Gapped Systems

1. Security:

The main advantage of air gapped systems is their increased security. By isolating these systems from the internet and other networks, it makes it nearly impossible for malicious actors to gain access to the system and any sensitive data contained within. This makes them an ideal choice for organizations that handle sensitive information such as government agencies, banks, and healthcare providers.

2. Reduced Maintenance Costs:

Another advantage of air gapped systems is their reduced maintenance costs. This can lead to significant cost savings in terms of both time and money for organizations that rely on these systems.

Limitations of Air Gapped Systems

1. Difficult to Implement:

One of the major drawbacks of air gapped systems is that they can be difficult to implement.  Additionally, these systems are often expensive to construct and require specialized knowledge in order to set up properly.

2. Limited Connectivity:

Another limitation of air gapped systems is their limited connectivity. This can be a major limitation for organizations that require frequent data transfer with outside sources.

3. Vulnerable to Physical Attacks:

Air gapped systems are not invulnerable to attack.  This makes air gapped systems vulnerable to both insider and external threats, making it important for organizations that use these systems to ensure their physical security is also up to par.

4. Prone to Human Error:

Finally, air gapped systems are prone to human error. As mentioned above, these systems require specialized knowledge and expertise in order to set up and manage properly.

Conclusion

Air gapped systems offer increased security and reduced maintenance costs, making them an ideal choice for organizations that handle sensitive information. However, they can also be difficult to implement and have limited connectivity which can make them a less attractive option for some organizations. Additionally, air gapped systems are still susceptible to physical attacks as well as human error which must be taken into consideration when deploying them. Ultimately, organizations must weigh the pros and cons of using air gapped systems in order to determine if they are an appropriate choice for their particular needs.

FAQs

1. What is an air gapped system?

An air gapped system is a computer or network that is completely isolated from the internet and any other external networks. This isolation provides an extra layer of security for sensitive data, making it more difficult for malicious actors to gain access to the system or its data.

2. What are the advantages of air gapped systems?

The main advantages of air gapped systems are increased security and reduced maintenance costs. By isolating the system from the internet and other networks, it becomes much more difficult for malicious actors to gain access to the system or any sensitive data contained within. Additionally, these systems do not require as frequent patching or updating, leading to greater cost savings.

3. What are the limitations of air gapped systems?

The main limitations of air gapped systems are their difficult implementation, limited connectivity, vulnerability to physical attacks and susceptibility to human error. Additionally, these systems may not be feasible for some organizations due to their complexity and cost.

4. Is an air gapped system secure?

An air gapped system can offer an extra layer of security, but it is not completely invulnerable to attack. It can still be compromised if someone is able to gain physical access to the system or its data, making it important for organizations that use these systems to ensure their physical security is up-to-date and properly configured. Additionally, air gapped systems can be susceptible to human error which must be taken into consideration when deploying them.

5. What factors should be considered when deploying an air gapped system?

When deploying an air gapped system, organizations should consider the complexity of the implementation process, the limited connectivity options available, their physical security measures and any potential human error risks that may arise.
