More ...

First, the user faces the risk at present, most application system mainly uses the traditional password authentication method to carry on the identity authentication. This kind of authentication way faces many attacks and the leakage risk, for example: The network eavesdropping (Sniffer), the authentication information interception/Replay (Record/replay), the virus, the hacker and so on, the traditional password authentication way already cannot satisfy the large-scale network application security authentication demand. 498) this.width=498 ' OnMouseWheel = ' javascript:return big (th ...

More and more data centers have been moved to a variety of clouds, server configuration is a problem to be considered.
