Which of the following is NOT a main feature of Edge security?

Access Control Lists (ACLs) are primarily used to define and manage permissions for users and applications attempting to access resources within a system. While they play a significant role in securing access to APIs and services, they are not typically classified as a feature specific to Edge security. Edge security primarily focuses on protecting the edge of a network, where external requests interface with internal services.

On the other hand, features like Denial of Service (DoS) protection, Quality of Service (QoS), and Content Security (CAP) are directly related to safeguarding against external threats and managing the traffic at the edge of your infrastructure.

DoS protection aims to prevent overwhelming a service with excessive requests, ensuring its availability. QoS ensures that network resources are allocated efficiently, maintaining performance and reliability, especially under heavy load. Content Security involves implementing measures to protect the integrity and confidentiality of the data transferred across the network.

In summary, while ACLs contribute to security, they do not fall under the core features typically associated with Edge security, which is focused on defending against external threats and managing traffic effectively.
