Distributed Denial of Service (DDoS) attacks are designed to overwhelm systems and take down critical services. In this episode, we explain how these attacks work—volumetric, protocol, and application-layer—and the techniques used to defend against them. You’ll learn about scrubbing centers, rate limiting, traffic shaping, and the role of content delivery networks in mitigation. We also explore how to design high-availability network architectures with redundancy, failover, and load balancing to ensure service continuity even under stress. CISSPs must be equipped to anticipate, prevent, and recover from large-scale disruption events.
