Frameworks that govern network architecture
What the standards actually require on network architecture
Requirements naming network architecture across 6 standards, quoted from the control text.
UR E26 Goal 1 (Identify) requires the shipyard + ship owner to maintain a comprehensive inventory of Computer Based Systems (CBS) onboard the ship.
IACS-UR-E26-Identify-AssetInventory-CBS-NetworkArchitecture-Risk · IACS UR E26 Identify Goal - Asset Inventory of Computer Based Systems + Network Architecture Documentation + Risk-Assessable Scope →Per TSA + Telecommunications Security Code of Practice: Network Architecture Hierarchy and Security Layers + security measures per code + Ofcom Code of Practice compliance.
UKTSA-2 · Code of Practice and Network Architecture →Network architecture shall be planned with zones of differing trust, segmentation, redundancy and documented in current diagrams.
NET.1.1 · Network Architecture and Design →Establish and maintain a secure network architecture. A secure network architecture must address segmentation, least privilege, and availability, at a minimum.
CIS-12.2 · Establish and Maintain a Secure Network Architecture →Design ICS network architecture using defined zones, a demilitarised zone (DMZ) between the control network and the corporate/enterprise network, and VLAN segmentation to separate functions and contain compromise.
CISA-ICS-DID-24 · ICS Network Architecture →Identify high-risk environments and document them in the network architecture record.
