An air gapped system is a type of network environment in which user and system data are kept isolated from all external networks. This type of security measure provides an extra layer of protection against attacks, as well as ensuring that sensitive information remains secure. By leveraging the strength of an air gapped system, organizations can rest assured that their data is safe and secure from malicious actors.
What is Air Gapped System?
Air gapped systems are networks that have been specifically designed to be isolated from all external sources. This type of security measure helps to protect against a variety of different threats including malware, viruses, and other malicious attacks.
Types of Air Gapped System
The most common types of air gapped systems are:
1. Local Network Air Gaps:
These are networks that have been specifically designed to be isolated from outside networks.
2. Wireless Air Gaps:
Wireless air gapped systems are designed to limit the spread of wireless signals, ensuring that only authorized users can access the network.
3. Air Gap Security Software:
This type of software is designed to detect suspicious activity and alert administrators as soon as a potential threat is detected.
Benefits of an Air Gapped System
1. Increased Security:
The most obvious benefit of an air gapped system is increased security. With an air gap, organizations can rest assured that their data is safe from external threats such as hackers and malicious actors.

10 Best Practices for Secure Air Gapping
1. Isolate Critical Data:
Organizations should isolate their most sensitive data on an air gapped system to ensure that it is secure from external threats. This includes any personal data, financial information, or other confidential documents.
2. Monitor Network Traffic:
Organizations should monitor network traffic for any suspicious activity. This includes keeping an eye out for any unauthorized access attempts or malicious programs attempting to enter the system.
3. Use Strong Encryption:
Organizations should use strong encryption algorithms to protect their data from external threats. This helps to ensure that only authorized users have access to the data, reducing the risk of a breach.
4. Implement Access Controls:
Organizations should also implement access controls to limit the number of users who can access sensitive data. This ensures that only authorized personnel can view and modify confidential information.
5. Use Firewalls:
Organizations should use firewalls to protect their air gapped systems from external threats. This helps to block any malicious programs that may attempt to enter the system.
6. Train Employees:
Organizations should also train their employees on air gapping best practices. This helps to ensure that all users are aware of the importance of security and how to protect their data from external threats.
7. Perform Regular Security Audits:
Organizations should also perform regular security audits to check for any vulnerabilities in their air gapped system. This helps to identify any security gaps that may be exploited by malicious actors.
8. Update Software:
Organizations should keep their software up-to-date with the latest patches and updates. This helps to ensure that all software is secure and that any newly discovered vulnerabilities are fixed promptly.
9. Utilize Security Tools:
Organizations should also utilize security tools such as antivirus software and intrusion detection systems to detect and prevent any malicious activity on the network.
10. Monitor User Activity:
Finally, organizations should monitor user activity to ensure that any unauthorized access attempts or suspicious activity is identified promptly. This helps to protect the air gapped system from external threats.
By following these best practices, organizations can ensure that their air gapped systems are secure and protected from external threats.
Conclusion
Air gapping is an effective security measure for organizations looking to protect their sensitive data. It helps to ensure that only authorized users have access to the data, reducing the risk of a breach. Additionally, air gapping can help organizations reduce their infrastructure costs and improve system performance. However, to maximize the security of an air gapped system, organizations should follow best practices such as isolating critical data, monitoring network traffic, and implementing access controls. By doing so, organizations can ensure that their air gapped system is secure and protected from external threats.
