The Basics of Air Gapped and How It's Used in Cybersecurity

The Basics of Air Gapped In Cybersecurity

Air Gapped is a security measure used to protect networks or systems from malicious outside interference. By keeping the network isolated, hackers, malware, and other malicious actors are unable to gain access to sensitive data or information stored on the network. This article will provide an overview of Air Gapped basics, its role in cybersecurity, and the importance of air gapping for enterprises.

What is Air Gapped?

Air gapping is a security technique that isolates networks or systems from being connected to any public network. It essentially creates an impenetrable physical barrier or "air gap" between the isolated and non-isolated networks. By keeping the isolated network completely separate from the outside world, it becomes much harder for malicious actors to gain access or compromise the information stored on that system.

How does it Work?

Air gapping can be implemented in a variety of ways. One example is disconnecting the isolated network from the internet. This means that there is no way for an outside attacker to access the network, since they lack a connection. Additionally, air gapping can be utilized by implementing strong firewalls and other security measures to protect against outside threats.

Benefits of Air Gapping for Enterprises:

Air gapping has several benefits for enterprises looking to improve their cybersecurity. These include:

Enhanced Security:

By preventing any external access to the isolated network, enterprises can be sure that all sensitive information stored on the system is safe and secure from malicious actors.

Improved Efficiency:

With an air gapped network in place, enterprises can save time and resources spent on security management as they will not need to worry about outside threats.

Cost Savings:

Air gapping can help enterprises save on costs associated with security measures since they do not need to rely on external systems or services for protection.

Reduced Risk of Breach:

By keeping the network isolated, enterprises reduce their risk of a breach as malicious actors have no way of accessing the system from outside.

Increased Compliance:

For enterprises that are subject to regulatory compliance, air gapping can help them meet their requirements by providing the necessary security measures.

Challenges of Implementing and Maintaining an Air Gapped Network:

Despite its benefits, there are a few challenges associated with implementing and maintaining an air gapped network. These include:

High Cost:

Establishing and maintaining an air gapped network can be expensive due to the cost of security measures, hardware, software, and personnel.

Complexity:

It can be difficult for IT personnel to configure the system correctly since there are many components involved in setting up an air gapped network.

Limited Accessibility:

Since the network is completely isolated, it can be difficult for authorized personnel to access data since they lack a connection to the system.

Lack of Updates and Support:

As the network is disconnected from any external sources, enterprises will not be able to receive updates or support should an issue arise with the system.

Conclusion

Air gapping is a powerful security measure used to protect sensitive information from malicious actors. It offers a number of benefits for enterprises, including enhanced security, improved efficiency, cost savings, reduced risk of breach, and increased compliance with regulations. However, there are some challenges associated with implementing and maintaining an air gapped network such as high costs, complexity of setup, lack of accessibility and support, and lack of updates. Enterprises should carefully consider the pros and cons before deciding if air gapping is the right solution for their cybersecurity needs.
