Design secure network architectures, components, protocols, segmentation, wireless, remote access, third-party connectivity, and communication channels.
Assess and implement segmentation, zero-trust concepts, software-defined networking, convergence, fault tolerance, and secure topology.
Understand operation and risk of transmission media, network access control, endpoints, devices, wireless, cellular, and content-distribution components.
Design voice, multimedia, remote-access, collaboration, data, API, virtualized, and third-party channels with appropriate protection.
Map zones, subjects, devices, applications, data, protocols, routes, name resolution, remote access, third parties, management planes, physical media, wireless/cellular links, monitoring, and failure paths.
Segmentation reduces unnecessary reachability but must be paired with identity, authorization, secure protocols, endpoint controls, monitoring, and lifecycle governance. Zero trust is a strategy of explicit verification, least privilege, continuous evaluation, and assumed breach—not a single product or the elimination of networks.
Understand device and protocol purpose across physical through application layers. Evaluate firewalls, proxies, gateways, IDS/IPS, network access control, load balancing, DNS, VPN, wireless, SDN, content delivery, and virtual network functions from placement, trust, state, failover, and evidence.
Protect voice, video, collaboration, remote access, APIs, data exchange, virtualized communication, and third-party connections using appropriate identity, encryption, integrity, availability, monitoring, and contractual controls.
Design a temporary merger connection. Explain how you constrain trust, authenticate users and devices, segment traffic, secure channels, monitor behavior, manage failure, and remove access after integration.
