Watchguard Network Security Practice Test

What should be done to reduce certificate errors in client browsers when using deep packet inspection?

1. Export proxy authority certificates to client devices.

2. Change proxy settings on all client devices.

3. Disable deep inspection for HTTPS.

4. Use a different method for content inspection.

The correct answer is: Export proxy authority certificates to client devices.

To effectively reduce certificate errors in client browsers when employing deep packet inspection, exporting proxy authority certificates to client devices is essential. This process allows the client devices to recognize and trust the certificates issued by the proxy server that is performing the deep packet inspection. When a proxy conducts deep packet inspection, it essentially intercepts and decrypts secure traffic (HTTPS) for the purpose of inspecting the data for potential threats. However, this means that the original certificate presented by the server is replaced with a certificate that the proxy generates. If client devices do not have the proxy's certificate in their trusted certificate store, they will flag this as a potential security issue, leading to certificate errors. By exporting and installing the proxy's authority certificate on all client devices, you establish a trust relationship. With the proxy certificate trusted, users will no longer receive warnings or errors related to the legitimacy of the SSL/TLS connection, allowing for a smoother user experience while still benefiting from the protective measures that deep packet inspection offers. In contrast, simply changing proxy settings on client devices may not address the core issue of certificate trust. Disabling deep inspection for HTTPS would stop the feature altogether, potentially exposing the network to threats, while using a different method for content inspection might not inherently resolve trust issues
