An Air Gap

A manufacturer creates designs for very high security products that are required to be protected and controlled by the government regulations.

These designs are not accessible by corporate networks or the Internet.

Which of the following is the BEST solution to protect these designs?

A.

An air gap

B.

A Faraday cage

C.

A shielded cable

D.

A demilitarized zone.

A.

The BEST solution to protect high-security designs that are not accessible by corporate networks or the internet is an "air gap" (Option A).

An air gap is a physical separation of a computer or network from any unsecured networks, such as the internet or a corporate network. This means that the computer or network is not connected to any other network, making it impossible for hackers or malicious actors to access it remotely. This method is often used in critical infrastructure, government facilities, and other high-security environments.

A Faraday cage (Option B) is an enclosure that is designed to block electromagnetic fields, such as radio waves, from entering or leaving the cage. It can be used to protect electronic equipment from electromagnetic interference (EMI) or to prevent eavesdropping on electronic signals. However, it does not provide the same level of protection as an air gap, as it only protects against certain types of attacks.

A shielded cable (Option C) is a cable that has a conductive layer or shielding around it to protect against electromagnetic interference (EMI) and radio frequency interference (RFI). It can be used to protect data transmissions from interference, but it does not provide the same level of protection as an air gap.

A demilitarized zone (Option D) is a network segment that is used to separate a trusted network from an untrusted network, such as the internet. It is often used in firewalls to provide an additional layer of security. However, it is not suitable for protecting high-security designs that are not accessible by corporate networks or the internet.

In summary, an air gap is the BEST solution to protect high-security designs that are not accessible by corporate networks or the internet, as it provides complete physical separation from unsecured networks.
