If you specify network-layer application-layer or application-layer network-layer in this command, both non-encrypted and encrypted traffic can be collected. During the collection of encrypted traffic, the Encrypted Communication Analytics (ECA) function is used. This function does not need to decrypt traffic. Instead, it collects SSL protocol negotiation information, packet statistics information, and DNS and HTTP protocol information of the traffic. Then it sends the information to the HiSec Insight in metadata format. The HiSec Insight analyzes and assesses the information to identify malicious encrypted traffic.
