What is an air gap? An air gap is a security measure that involves isolating a computer or network from other systems, especially the internet. This separation ensures that sensitive data remains protected from cyber threats. Why is it important? Air gaps are crucial for safeguarding critical infrastructure, military secrets, and financial systems. They act as a physical barrier, making it nearly impossible for hackers to access the isolated system remotely. How does it work? By physically disconnecting the device from any network, air gaps eliminate the risk of remote hacking. This method is often used in environments where data security is paramount. Are there any downsides? While highly secure, air gaps can make data transfer cumbersome and limit system functionality. However, the trade-off is often worth it for the enhanced security.
