õhuvaheli

Õhuvaheli, also known as "air gap," refers to the physical separation between two or more computer networks or systems. This separation is designed to prevent the spread of malware, viruses, or other malicious software from one network to another. The concept of an air gap is particularly relevant in critical infrastructure, military, and government systems where security is paramount.

The primary purpose of an air gap is to create a barrier that prevents unauthorized access and the transmission of data between networks. This is achieved by physically disconnecting the networks, often by using separate hardware and software environments. In some cases, data may be transferred between air-gapped networks using physical media such as USB drives, CDs, or other removable storage devices.

While air gaps provide a high level of security, they are not without limitations. They can be difficult and costly to implement and maintain, and they may not be effective against all types of threats, such as advanced persistent threats (APTs) that can exploit human factors or use social engineering techniques. Additionally, air gaps can create operational challenges, as they may require manual data transfer processes and can limit the ability to share information and collaborate across networks.

In summary, õhuvaheli, or air gap, is a security measure used to prevent the spread of malware and unauthorized access between computer networks or systems. While it provides a high level of security, it also has limitations and operational challenges that must be carefully considered.
