This document is meant to provide guidance to this new enterprise network landscape from a secure operations perspective. Hence, it starts by examining the security limitations of current network access solutions to the enterprise network. It then considers security feature enhancements to traditional network appliances in the form of point security solutions, network configurations for various security functions (e.g., application/services security, cloud services access security, device or endpoint security), security frameworks that integrate these individual network configurations (e.g., zero trust network access [ZTNA]), and the evolving wide area network (WAN) infrastructure to provide a comprehensive set of security services for the modern enterprise network landscape (e.g., secure access service edge [SASE]).
