Question

How does air gap networking seek to keep a system secure?

1) by taking extra steps to ensure the dmz server is fully patched to deal with the latest exploits
2) by physically isolating it from all unsecured networks, such as the internet or a lan
3) by focusing on the security of the system through detection devices and incident reports
4) by keeping the rules monitoring traffic between the lan and a network as tight as possible

Answer 1

Air gap networking secures a system by physically separating it from unsecured networks, which prevents unauthorized access and reduces the risk of cyber threats. It is an effective barrier analogous to creating a 'moat' around a castle, though it can entail challenges like the digital divide and dependency on limited tech interactions.

Step-by-step explanation:

Air gap networking is a security measure that involves physically isolating a computer or network from unsecured networks, such as the Internet or a local area network (LAN). The goal is to prevent unauthorized access and ensure that sensitive information remains protected from external threats. By not connecting to other networks, an air-gapped system significantly reduces the risk of cyber attacks, data breaches, and infection by malware that could compromise the system. This approach is akin to creating a 'moat' around a castle.

Option 2 in the provided question is the correct answer because air gap networking ensures security by physically isolating the system from all unsecured networks. Unlike other methods that rely on software-based security measures, physical isolation provides a barrier that is not easily breached as there is no direct path for digital communication to occur with external systems or networks. While this method can be highly effective, it may also introduce challenges such as the 'digital divide' and increased dependency on limited technological interactions within the secured environment.
