Which traffic type can utilize the Intrusion Prevention Service to detect threats?

The correct answer is that unencrypted web traffic can utilize the Intrusion Prevention Service (IPS) to detect threats. The IPS analyzes network traffic in real-time, allowing it to inspect the content of the packets being transmitted. Unencrypted web traffic is in plain text, enabling the IPS to effectively analyze and identify potentially harmful patterns or known threats within the data.

While encrypted email traffic does pass through the IPS, the encryption obscures the contents, making it challenging for the IPS to perform a thorough inspection. In this scenario, the IPS would be limited in its ability to detect threats since it cannot analyze the actual data being transferred.

Considering all traffic types, it is accurate to say that IPS can provide protection across different layers, but its effectiveness is significantly reduced for encrypted data compared to unencrypted data. Therefore, the ability to fully analyze only applies to unencrypted traffic where the IPS can fully inspect the content for vulnerabilities and threats.
