 Port Security is a network security feature on switches that allows the specification of which MAC addresses are permitted on each physical port. When Port Security is enabled, the switch will only permit traffic from the allowed MAC addresses to pass through the specified port, effectively preventing unauthorized devices from accessing the network through that port. This feature is particularly useful for controlling access on a network and ensuring that only known devices can communicate through the switch, thereby increasing the security of the network.

References: The information provided is consistent with standard network security practices and the functionalities of Port Security as described in network security resources and documentation123.

In the context of IoT Architecture, the Process Layer is responsible for providing dashboards that are used to monitor, analyze, and implement proactive decisions. This layer encompasses the software platforms and applications that process the data collected from the devices. It is within this layer that data is turned into actionable insights and where dashboards are typically found, allowing for real-time monitoring and analysis, as well as the ability to make proactive decisions based on the processed information.

References: The information aligns with the general structure of IoT systems, where the Process Layer serves as the interface for user interaction and data manipulation. It is consistent with the descriptions provided in IoT architecture resources123.

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.

References: The explanation provided is based on the official Docker documentation, which outlines the responsibilities and functionalities of the Docker daemon in the context of container management1.

The measures Damian is implementing are part of the Physical layer of network defense-in-depth strategy. This layer involves securing the physical infrastructure of the organization, which includes controlling physical access to the building through mechanisms like two-factor authenticated locks and monitoring the environment with video surveillance. Additionally, implementing fire suppression systems is a part of safeguarding the physical premises against environmental hazards. These measures are essential to prevent unauthorized physical access and to protect against physical threats that could harm the network’s infrastructure. References: The Certified Network Defender (CND) program by EC-Council covers a defense-in-depth security strategy that includes the Physical layer as one of its core components12.
