Dedicated Servers
A secure server is a server for html pages (like services World Wide Web) that establishes a connection to the client, so that the information circulating through the Internet encrypted using algorithms that ensure it is intelligible only to the server and the viewer accessing the web.
A secure server is the necessary platform that allows service involving the transfer of information whose confidentiality must be protected. Is a prerequisite for the establishment of e-banking services or electronic commerce.
How can I tell if a server is secure?
It's easy to know if we are connected to a secure server. First, the URL address begins with https: / / instead of http:// (this address is accessed, sometimes without user intervention, because you press a key word that incorporates or well when you want to intentionally access a server in safe mode). In addition, the majority of viewers will have an indication that the secure connection has been established. Thus, for example with the Netscape browser are the following:
The key to the bottom left, which usually appears heading is complete. A blue line in the upper limit of the display area.
The document includes information from the certificate data. Depending on the version of Netscape, this information is in the section File or View.
Other browsers have different icons to display secure connections, such as Microsoft Internet Explorer.
How does a secure server?
Secure Dedicated Server
A secure server works as follows:
A customer accesses the web address of insurance through its URL, eg https: / / www.example.com. Once the connection is established, the browser requests a secure connection. If the server being accessed is a secure server, respond affirmatively to the request by sending an electronic certificate of type RSA. After receiving this certificate, you unpack the display with the key of the certifying authority, and integrated into the software, thereby obtaining the second key RSA algorithm. Finally, the client generates a symmetric encryption key according to the algorithm RC4 encrypted and sent to the server (with your public key). From this point, both client and server can establish a secure communication based on the symmetric key, which they and only they know.
Symmetric keys are generated randomly in each session, so there is no possibility that these are known to potential hackers.
