"This guideline is intended to assist network architects and security practitioners with the appropriate placement of services (for example, domain name service, email service, and web proxy service) into network security zones. A service is a logical construct that represent a set of functional requirements in an information technology architecture. These functional requirements can be simple such as providing resolution of domain names, or complex such as processing and transmitting email. Services can be physically implemented in many ways, for example, a single process on server, multiple processes on a virtual machine, or distributed processes among pool of servers. Concepts used in this document are based on the Baseline Security Requirements for Network Security Zones in the Government of Canada (ITSG-22), which describes the concepts of network security zones and specifies baseline security requirements for zone"--Executive summary, page iii. gccst Federal government gccst Computer security Communications Security Establishment (Canada) Établissement des zones de sécurité dans un réseau : (CaOODSP)9.869720 PDF 1.29 MB https://publications.gc.ca/collections/collection_2019/cstc-csec/D96-8-38-2009-eng.pdf HTML N/A https://cyber.gc.ca/en/guidance/network-security-zoning-design-considerations-placement-services-within-zones-itsg-38
