What are the three main features of Edge security?

• A. CAP: Content Security; QoS: Quality of Service; DoS: Denial of Service
• B. CAP: Content Access Policy; QoS: Quick Optimization Service; DoS: Data on System
• C. CAP: Cache and Proxy; QoS: Quality of Signals; DoS: Denial of Service
• D. CAP: Content Security; QoS: Quality of Service; IDS: Intrusion Detection System

Answer: (A)

Edge security at the edge revolves around three core ideas: protecting the content itself, keeping security controls from harming performance, and defending availability against attacks. Content Security means ensuring the integrity and authenticity of content delivered at the edge. It covers measures like verifying sources, signing content, and using trusted delivery paths so that what reaches the user isn’t tampered with or spoofed. Quality of Service in this context emphasizes that security measures should preserve reliable performance. It includes mechanisms such as rate limiting, traffic shaping, and prioritization so that protective controls don’t become a bottleneck or degrade user experience during normal or peak loads. Denial of Service protection focuses on keeping services available by detecting and mitigating floods of traffic or abusive patterns. This involves filtering malicious requests, throttling, and other safeguards to prevent edge resources from being overwhelmed. The other options either use nonstandard expansions for CAP or mix in terms that aren’t typical security features at the edge (like Cache and Proxy), or replace a security control with a different tool (such as IDS) that isn’t listed as a primary edge security feature in this context. The combination of Content Security, Quality of Service, and Denial of Service protection best captures these three essential aspects of edge security.
