ESCADA Network Architecture Requirements Develop a comprehensive network Landing Zone strategy for deployment on On-Premise, AWS, or Azure, based on the selected hosting environment. Implement an OT Zero Trust LAN framework, incorporating VNETs, Subnets, and IP allocations for the eSCADA system. Design a high-performance and resilient Wide Area Network (WAN) connectivity model that securely links the On-Premise Teri network to the preferred hosting platform. This should include seamless end-to-end routing for outstations/sites via the STW network infrastructure, supporting multiple connectivity options such as PSTN, ISDN, 4G Arkessa, and MPLS-based OT networks. Assess the current network infrastructure supporting both existing and new eSCADA implementations, identifying any end-of-life (EOL) components and potential risk areas. Required Knowledge & Skills Expertise in On-Premise networking, including core and edge routers, firewalls, switches, and VPN concentrators.
