Wireless security: Moxa offers WPA2 Personal and Enterprise
Among wireless options, Moxa Technologies currently supports WPA2 Personal and Enterprise, explains Jim Toepper, Moxa Americas product marketing manager, Industrial Wireless and Connectivity Group. Toepper told Control Engineering :
-This level of encryption and authentication offers the best security commercially available for wireless connections. It is also considered best practice.
-Encryption method is AES, the government standard, and the authentication is IEEE 802.1x, which means it uses a Radius server; 802.1x means that only username and password can be communicated over the network until the client is granted access. Once access is granted, the client will have normal use of the network.
-Having authentication on the inside of the network lessens the likelihood of someone hacking into the network.
-WPA2 Personal mode or WPA2-PSK (Pre shared key) does the authentication at the edge of the network. This, by definition, is more risky because of the accessibility of the Wireless server.
For more information, there’s a Moxa Wi-Fi whitepaper, "Site Planning and Wireless Network Installation ," which explains why someone should choose wireless networking, site planning, which technologies match what application needs, distance, coverage, and antennae, site survey tools, and other tips.
