Remote Access Dial-Up User Service or in short "RADIUS" is another standard technology that is already in use by many major business houses to protect access to wireless networks. It is a user name and password scheme that enables only approved users to access the network; it does not affect or encrypt data. The first time a user wants access to the network, secure files or net locations, he or she must input his or her name and password and submit it over the network to the RADIUS server. The server then verifies that the individual has an account and, if so, ensures that the person uses the correct password before she or he can get on the network.

Access Point

It can be set up to supply diverse access levels or classes of access. For example, one level can provide blanket access to the Internet; another can provide access to the Internet as well as to e-mail communications; yet another account class can provide access to the Net, email and the secure business file server.

Technologies

RADIUS comes in a variety of types and levels like other sophisticated security technologies that have already mentioned. One can use the free RADIUS provided by Microsoft for its advanced server operating systems. One can even use the sophisticated hardware and software solution of the Microsoft.
