You have configured a security device in your network to fail-closed. Which of the following will happen when an attack occurs? The device will block access or enter the most secure state available when it fails. The device will act on behalf of a client when accessing resources over the internet when it fails. The device will distribute network traffic across multiple servers when it fails. The device will preserve network or host access when it fails.

When a security device is configured to fail-closed, it means that in the event of a failure or attack, it will block access to the resources it protects, effectively entering the most secure state possible. This is a precautionary measure; better to restrict access than to allow potentially malicious traffic into your network! Also, it's interesting to note that this fail-closed approach is particularly crucial for industries handling sensitive data, like healthcare and finance. In such cases, even a momentary lapse in security could lead to serious breaches. Organizations often utilize layered security measures to ensure that if one device fails, others can mitigate the risk.
