NIST SP 800-215 provides guidance from a secure operations perspective. This transformation has the following security impacts: (a) disappearance of the concept of a perimeter associated with the enterprise network, (b) an increase in attack surfaces due to the sheer multiplicity of IT resource components (e.g., computing, networking, and storage), and (c) the ability of attackers to escalate sophisticated attacks across several network boundaries by leveraging extensive connectivity features within and across the individual network segments. NIST has published Special Publication (SP) 800-215, Guide to a Secure Enterprise Network Landscape.Īccess to multiple cloud services (e.g., IaaS, SaaS), the geographic spread of enterprise Information Technology (IT) resources (including multiple data centers and multiple branch offices), and the emergence of highly distributed loosely coupled microservices-based applications (as opposed to monolithic ones) have significantly altered the enterprise network landscape.
