Episode 68: Content Delivery Networks and Edge Security

Content Delivery Networks (CDNs) accelerate access to web content by distributing it across global edge nodes, but they also introduce new attack surfaces. In this episode, we discuss how CDNs work, their role in performance optimization, and the security challenges they present, such as cache poisoning, misconfigured access controls, and DDoS targeting. We also explore edge computing security—protecting data and services closer to the end user. CISSPs must understand how to secure the entire content delivery path, from cloud origin to user browser, while balancing speed, scalability, and control.
