Network Device and Transmission Media Vulnerabilities

Wired and wireless networking relies on a system of underlying devices responsible for coordinating the transport and security of networked data. Namespace services facilitate translation from human-readable addresses to their numeric equivalents, where routers then determine the proper network connections to transfer data packets to identified endpoint network segments. Switches and hubs allow distribtion of data packets to individual endpoints, with myriad dedicated transport systems available for encryption, access control, and other functions necessary to internetwork communications.

You should be familiar with vulnerabilities associated with these network devices, including the following:
