Securing Cisco Digital Network Architecture (DNASEC) 1.0

COURSE OUTLINE:

Description

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.
