What you'll learn

Modern enterprise networks expose wired, wireless, and cloud edges that demand layered security. In this course, Cisco Enterprise Networks: Securing Network Traffic, you’ll gain the ability to describe and implement key network security controls across the Cisco ENCOR blueprint. First, you’ll explore threat defense systems including Talos intelligence, AMP for Endpoints, Umbrella DNS protection, and Firepower NGFW policy flow. Next, you’ll discover how to apply access control and segmentation using ISE, TrustSec SGTs, and MACsec. Finally, you’ll learn to configure and verify secure WLANs on a Catalyst 9800-CL controller, including WPA2-Enterprise with FreeRADIUS, WebAuth guest portals, and WPA2-PSK for IoT. When you’re finished with this course, you’ll have the skills and knowledge of Cisco ENCOR network security needed to design, implement, and validate protections across campus and branch environments.
