The role of network switches in providing security has been highlighted.
Writing on Embedded.com, Sebastien Brun points out the IEEE's 802.1x standard works to prevent the access of hackers and other threats to a network by only allowing authorised devices to gain access to it.
The standard prevents a device from being part of data traffic unless it has been authenticated, reducing the risk of malicious attacks on local area network (LAN) or other systems.
According to the article, three elements are involved in the authentication process, with the first being the supplicant, or the device trying to gain access.
Usually, a network switch acts as the second element, working as the main block to the device gaining access to the (LAN).
Mr Brun writes: "Typically, traffic of any unoccupied access point to a network, such as a port on a wired or wireless Ethernet switch, is blocked until the 802.1x authentication process has completed."
In addition, the third part of the process is the authenticating server, which approves the supplicant and tells the network switch to grant it access to the LAN.
Recently, Curt Carlson wrote on Communications News that using the correct network cables can improve the performance of video security cameras.
