Here are some guidelines for applying layered security to universal customer premises equipment (uCPE) deployments. The uCPE layers include the platform layer (including management, virtualization, and networking), the application layer, and the management and orchestration (MANO) layer. As a reminder, uCPE consists of software virtual network functions (VNFs) running on a standard operating system hosted on a standard server. An ideal uCPE deployment supports a multi-vendor multi-component construction, underscoring the need for security at multiple layers ...
