Encrypted Traffic Analytics and SD-Access integrate security into the enterprise network.
Security is a big part of Cisco's new intent-based networking strategy. The key security pieces are Encrypted Traffic Analytics and Software-Defined Access. The details of hardware support such as the Catalyst 9000 switches aren't as important as how the new architecture provides a new way for enterprises to approach security by integrating it into the network.
Encrypted Traffic Analytics (ETA) enables detection of malware in encrypted network traffic. This is important since encrypted traffic is becoming popular and enterprises cannot rely on deep-packet inspection for malware detection. A Cisco white paper provides details of ETA. Those who are academically inclined can read a technical paper from the 2016 ACM Workshop on Artificial Intelligence and Security.
