Ensuring industrial wireless security

摘要

Julia Santogatta, director of wireless initiatives at Belden, looks at the security concerns associated with wireless networks, and explains how these can be overcome. The biggest concern about wireless solutions in the industrial world often comes down to either reliability or security. However, on a wired network, passwords are not generally needed to plug a PC into a router and get onto the network. Further, there is no requirement for the data to be encrypted. Hubs can be laid down using tools such as Wireshark with all of the data streams being visible. This is not the case with wireless, even with only the most basic and common security measures in place. Wireless has extensive built-in security and, as the standards evolve, mandated security requirements have expanded, making wireless inherently more secure.
