K
Key
A cipher used to encrypt and decrypt information. Two types of keys are used:
public and private. Public keys are shared; private keys are not. Public and
private keys work together: information encrypted by the public key can be
decrypted only by the private key.
Key Strength
The length of a key, expressed in bits, e.g., 56 or 128. The greater the number of
bits, the stronger the key.
L
Load Balancing
Distributing network traffic evenly over two or more servers to provide better
response times and reduce server overload.
Logical Secure
Server
The SSL configuration consisting of an IP address for the hardware web server
providing content, an SSL TCP service port specification, a clear text port
specification, a key association specifying the key and certificate to use when
processing transactions, and a security policy specifying the cryptographic
scheme(s) to use.
R
Remote Port
The user-specified non-secure TCP port used by the Cisco Secure Content
Accelerator to send decrypted data to and receive data to be encrypted from the
logical secure server.
Reverse-Proxy
Server
A secure server responsible for offloading SSL processing for the client. The
client browser is configured to use the IP address of the reverse-proxy server as
a proxy. The reverse-proxy server is set to listen for clear text on the specified
port (usually 81 or 8080). DNS information must be configured on the
reverse-proxy server.
