DNASEC: Securing Cisco Digital Network Architecture

Many challenges exist managing modern networks on a day to day basis. The problems are intensified when manual configuration changes using fragmented tool offerings result in non-centralized change and configuration management which leads to various naming, configuration, backup and security compliance issues. Manual configuration changes when compared to automated, policy-based approaches are slow and error-prone. Break and fix, new network builds and change requests in dynamic environments where user requirements, devices and applications are evolving at ever increasing rates fueled in many cases by the big data of IoT. The networks of today face deployment, support and security challenges mitigated with modern tools such as Digital Network Architecture Centre (DNAC), Cisco Identity Services Engine (ISE) and Stealthwatch. In this course, you use these tools to build a centrally managed, authenticated, authorized, monitored and security-policy compliant solution.
