In the context of DDoS (Distributed Denial of Service) attacks, a network-centric attack is one that targets the network layer of a system's architecture. This type of attack aims to overload a service by inundating it with a flood of packets, which can be achieved through methods like ICMP floods or UDP floods. These attacks consume the bandwidth of the targeted site, effectively saturating it with traffic and preventing legitimate traffic from being processed.

The Docker Daemon is responsible for managing Docker images, containers, networks, and storage volumes, as well as processing requests from the Docker API. The Docker daemon (dockerd) listens for Docker API requests and manages these Docker objects1. It is a background service that manages the Docker containers and handles the container life cycle, which includes running, stopping, and deleting containers. It also manages networking for the containers and the storage volumes that containers use.
