With cyber-crime on the rise, organizations need to take extra steps to protect their valuable data. One of the most effective methods for keeping data secure is by using an air gapped system. An air gapped system is a security measure that creates a physical barrier between computers. This article will provide an overview of what an Air Gapped System is and how it can help keep your data secure.
Define Air Gapped System?
An air gapped system is a method of isolating computers or networks from any form of outside access. This includes both physical and wireless connections. The idea behind this system is to create an impenetrable barrier between the data stored within and any potential attackers.
How Does Air Gapped System Work?
To create an air gapped system, all physical connections must be blocked. This includes any cables that connect the network to other networks or external sources of data. Network administrators will also need to configure any firewalls and anti-virus software to limit access and prevent any malicious code from infiltrating the system.
Types of Air Gapped System
There are four main types of air gapped systems:
1. The Stand Alone System –
This type of system is completely isolated from any other systems. All data and software must be installed manually, and no external sources are allowed to access the system.
2. The Private Network –
This type of system connects only two or more computers on a private local area network (LAN).

3. The Subnet –
This type of system creates an isolated network within a larger one.
4. The Intranet –
This type of system is a secure, internal network that consists of multiple computers and other devices.
Benefits of Air Gapped System
By using an air gapped system, organizations can protect both their data and resources from outside threats.
1. Increased Security –
An air gapped system reduces the chances of data being stolen, corrupted or otherwise compromised by malicious actors. It also prevents unauthorized access to sensitive information and prevents any potential attackers from gaining a foothold in the system.
2. Improved Efficiency –
By isolating systems from outside sources, organizations can reduce their dependency on external resources and improve the overall efficiency of their networks.

3. Reduced Cost –
By eliminating the need for expensive hardware, such as firewalls and anti-virus software, organizations can save money on IT expenses. Additionally, air gapped systems require less maintenance than other security measures.
4. Improved Compliance –
Many regulatory bodies require organizations to use air gapped systems as part of their compliance requirements.
5. Increased Privacy –
Air gapped systems also provide an additional layer of privacy for users, as they are unable to access any outside resources or be targeted by malicious actors. This helps to protect the confidentiality of sensitive data and personal information.
Disadvantages of Air Gapped System
1. Limited Accessibility –
By isolating computers and networks from external sources, air gapped systems reduce the convenience and accessibility of data. This can be especially inconvenient for remote workers or anyone who needs to access files stored on an air gapped system.
2. Vulnerability to Internal Threats –
While air gapped systems reduce the chances of external attacks, they are still vulnerable to internal threats. As such, organizations need to take extra measures to protect their systems from malicious actors on the inside.
3. High Maintenance –
Air gapped systems require regular maintenance and monitoring in order to ensure that all connections remain secure. This can be time-consuming and expensive, especially for larger networks.
4. Costly Upgrades –
Upgrading an air gapped system can be costlier than upgrading other types of networks due to the extra security measures that have to be implemented.
5. Limited Scalability –
Air gapped systems are not easy to scale, as they require extra hardware and security measures in order to be effective. This can be a challenge for organizations that need to expand their networks quickly or efficiently.
Conclusion
Air gapped systems are a powerful security measure that can protect organizations from external threats. However, they also have their own set of drawbacks, including limited accessibility, vulnerability to internal threats, high maintenance and costly upgrades. Organizations need to weigh the pros and cons carefully before deciding if an air gapped system is the right solution for them.
FAQs
1. What is an air gapped system?
An air gapped system is a computer network or system that has been physically isolated from any external networks, such as the internet or other public networks. This isolation ensures that data and resources remain secure and private.
2. Why would I use an air gapped system?
Organizations can use air gapped systems to protect their data from malicious actors and unauthorized access. They can also help organizations meet their compliance requirements and provide an additional layer of privacy for users.
3. What are the disadvantages of an air gapped system?
Some of the disadvantages of an air gapped system include limited accessibility, vulnerability to internal threats, high maintenance, costly upgrades, and limited scalability.
4. Are air gapped systems expensive?
Upgrading an air gapped system can be costlier than upgrading other types of networks due to the extra security measures that have to be implemented. Organizations should weigh the pros and cons carefully before deciding if an air gapped system is right for them.
5. Are there alternatives to air gapped systems?
Yes, organizations can use other security solutions such as firewalls and antivirus software in order to protect their data from external threats. However, these solutions are not as effective at protecting against internal threats or providing an extra layer of privacy for users
