Securing Cisco Digital Network Architecture (DNASEC)
DNASEC focuses on securing Cisco's Digital Network Architecture by integrating policy, segmentation, and threat protection across wired and wireless infrastructure. It uses Cisco DNA Center, Identity Services Engine (ISE), and TrustSec to provide visibility, control, and enforcement in a unified manner.
Key Features of Securing Cisco Digital Network Architecture (DNASEC)
- End-to-end network segmentation and access control
- Policy-based security using Cisco TrustSec and SGTs
- Threat detection and response through integrated tools
- Identity-based access for users and devices
- Real-time telemetry and analytics for security assurance
Before learning DNASEC, you should have a strong foundation in networking concepts, including routing, switching, and security protocols. Familiarity with Cisco platforms, especially Cisco DNA Center, is important. Basic knowledge of network security principles, such as encryption and access control, will be beneficial.
