What is an Air Gapped Network? In today's digital age, securing sensitive information has become a top priority for many individuals and organizations. One of the ways to achieve this is by using an air-gapped network. An air-gapped network is a system that is physically isolated from the internet or any other unsecured network. It is often used to protect highly sensitive data, such as government secrets, financial information, and intellectual property. In this article, we will discuss what an air-gapped network is, how it works, and why it is essential for cybersecurity.
What is an Air Gapped Network?
An air-gapped network is a computer system that has been physically isolated from the internet or any other unsecured network. It does not connect to the internet directly and can only be accessed by authorized personnel with the necessary credentials. The name “air gapped” comes from the fact that there is an actual physical gap between the device and any other network. This prevents the transmission of data between the air gapped device and any other unsecured network.
How Does an Air Gapped Network Work?
An air-gapped network is typically implemented in three steps: isolation, authentication, and encryption.
First, the system is physically isolated from any external networks by using physical barriers such as firewalls, routers, or switches. This ensures that the system is completely inaccessible from outside sources.
Second, authentication protocols are used to ensure only authorized personnel can access the network. Typically, this involves a combination of usernames and passwords along with two-factor authentication methods like biometric scanners or keycards.
Types of Air Gapped Networks
There are two types of air gapped networks:
1. Intranet Air Gaps:
An intranet air gap is a network that has been completely isolated from the internet. It can only be accessed by authorized personnel within the same organization, such as employees or members of the organization’s IT team.
2. Extranet Air Gaps:
An extranet air gap is a network that can be accessed by authorized personnel outside of the organization. For example, an extranet air gap could be used to securely share documents or data with trusted partners or clients.
Conclusion
Air gapped networks are an essential part of any organization’s cybersecurity strategy. By physically isolating a system from the internet, organizations can protect their sensitive data from cybercriminals and hackers. Additionally, air gapped networks allow organizations to securely share documents or data with trusted partners without having to worry about potential security breaches. From government secrets to financial information, air gapped networks are an essential tool for protecting your data.
