The national mission teams operate on all types of networks. To defend a network, you must first understand the network design on which you are operating. Provide a brief description of each of the following network topologies:.

Our employees must have a theoretical and applicable understanding of how networking works. Name each layer of the OSI model. Provide the layer number and name from top to bottom..

Briefly describe each function of the OSI model layer. Provide the layer name and the function in your response..

Describe the purpose of an autonomous system.. Autonomous Systems are the core building blocks of the internet, allowing for efficient routing, policy enforcement, and scalability over the extensive network of linked networks that comprise the global internet. Imagine the internet as a massive freeway system. Autonomous Systems function similarly to individual states or provinces in this system. Each state has its road network (internal networks inside the AS), but they all communicate and interact through traffic regulations (routing policies). Each state's primary transportation agency (administrative control) administers these internal roads and their relationship to the more extensive highway system. Autonomous Systems bring a host of benefits to the internet infrastructure. These include scalability, efficiency, policy enforcement, and hierarchical routing. By dividing the internet into smaller, more manageable Autonomous Systems, we can effectively control it. Each AS can create unique routing regulations to meet specific needs and provide hierarchical routing between various networks on the internet..
