Watchguard Network Security Practice Test

To prevent certificate error warnings when using deep content inspection with the HTTPS proxy, what can be done?

1. Export the proxy authority certificate from the Firebox and import to client devices.

2. Change browser settings to ignore certificate warnings.

3. Use a different web proxy for visitations.

4. Disable deep content inspection altogether.

The correct answer is: Export the proxy authority certificate from the Firebox and import to client devices.

To prevent certificate error warnings when using deep content inspection with the HTTPS proxy, exporting the proxy authority certificate from the Firebox and importing it into client devices is the correct approach. This process involves creating a trust chain between the proxy and the client devices, allowing the clients to recognize and trust the proxy's certificate. When deep content inspection intercepts HTTPS traffic, it generates its own certificate to perform the inspection. If client devices do not trust this certificate, users will experience warnings about an untrusted source. By exporting the proxy authority certificate and importing it into each client's trusted certificate store, users can avoid these warnings. This ensures that the HTTPS traffic can be decrypted and inspected without affecting the user experience on the client devices. The other options do not address the core issue of trust that causes the certificate warnings. Changing browser settings to ignore certificate warnings might bypass the immediate issue but does not offer a secure or recommended long-term solution; it can expose users to security risks. Using a different web proxy may circumvent the problem temporarily but does not resolve the issues associated with the current setup; it could also involve additional costs or complications. Finally, disabling deep content inspection altogether negates the security benefits provided by inspecting traffic for malware or other threats, leaving the network more vulnerable
