Secure Network Architecture

Introduction

This lesson covers task 4.1 of Domain 4, Communication and Network Security (13% of the exam, ISC2 exam outline effective 15 April 2024): apply secure design principles in network architecture. The 2024 outline puts more weight on how traffic moves (layers, planes, forwarding) and on performance measures (bandwidth, throughput, latency, jitter, signal quality) than earlier versions did.
