Guide to a Secure Enterprise Network Landscape: NIST Requests Comments on Draft SP 800-215
August 05, 2022

The enterprise network landscape has undergone a significant transformation in the last decade. The drivers for this transformation are enterprise access to multiple cloud services, the geographic spread of enterprise-owned (on-premises) IT resources (e.g., in a central office, multiple branch offices, and data centers), and changes to application architecture from being monolithic to a set of loosely coupled microservices. The transformation has the following security impacts: (a) disappearance of the concept of a perimeter associated with the enterprise network; (b) an increase in attack surface due to the sheer multiplicity of IT resource components; and (c) sophistication of the attackers in their ability to escalate attacks across several network boundaries leveraging the connectivity features.

The initial public draft of NIST Special Publication (SP) 800-215, Guide to a Secure Enterprise Network Landscape, provides guidance for navigating this new enterprise network landscape from a secure operations perspective. It examines the security limitations of current network access solutions and point security solutions through traditional appliances with enhanced security features. It also considers new appliances, emerging network configurations, frameworks that incorporate the configurations, and cloud-based wide area network (WAN) services with integrated security infrastructures.

The public comment period is open through September 19, 2022. See the publication details for a copy of the draft and instructions for submitting comments.
