Internet Security Technologies : SSL (Secure Socket Layer)
Written on November 10, 2010 by Jerson
SSL (Secure Socket Layer) :
Netscape Communications Corporation developed SSL for providing security and privacy over the Internet. The protocol supports server and client authentication. Since the protocol is application-independent, it allows other protocols like HTTP, FTP, and Telnet to be transparently layered on it. An Secure Socket Layer (SSL)-enhanced browser encrypts the data sent from the browser to the server. SSL uses encryption and certificates to authenticate websites and web users.
Ssh (Secure Shell) :
Ssh is a program used to:
1. log into another computer over the network
2. execute commands in a remote system
3. move files from one system to another
Ssh provides:
1. strong authentication and secure communication over unsecured channels
2. secure connections and secure forwarding of arbitrary TCP connections
3. provides encrypted communication
4. Ssh is proposed as an alternative to the traditional BSD ‘r’ commands-rlogin, rsh, and rcp. It replaces Telnet. The free version of the SSH protocol suite can be downloaded from http://www.openssh.com/.
