Choose the protocol used by a web server to encrypt data.
A.
ActiveX
B.
TCP/IP (Transmission Control Protocol/Internet Protocol)
C.
SSL (Secure Sockets Layer)
D.
IPSec (Internet Protocol Security)
Explanation:
The Secure Socket Layer is used to establish a secure communication connection between two
TCP-based machines. This protocol uses the handshake method. When a connection request is
made to the server, the server sends a message back to the client indicating a secure connection
is needed. The client then sends the server a certificate indicating the capabilities of the client. The
server then evaluates the certificate and responds with a session key and an encrypted private
key. The session is secure after this process.
