What type of inspection is necessary to analyze HTTPS content effectively?

Deep packet inspection is necessary to analyze HTTPS content effectively because it allows for the examination of the data packets transmitted between the client and server. HTTPS encrypts data to secure communications, meaning that standard inspection methods cannot access the actual content being transmitted.

By employing deep packet inspection, a firewall or network security device can decrypt the HTTPS traffic, analyze it for potential threats such as malware or unauthorized content, and then re-encrypt it before it continues to its destination. This process not only enhances security by enabling oversight of secure transactions but also ensures compliance with organizational policies regarding acceptable content.

In contrast, standard inspection does not delve into the contents of the packets sufficiently to assess encrypted traffic, while application filtering and content filtering primarily focus on filtering traffic based on known applications or specific content types, respectively, rather than performing complex investigations into encrypted data.
