B |
|
Backend Server | Secure server responsible for offloading SSL processing for the client. A backend server listens for clear text from the client, encrypts the data, and connects via SSL to the server. |
C |
|
Certificate | Digital information that proves the identify of the server; similar to a digital ID card. Certificates are issued by Certificate Authorities. |
Cipher | An encryption algorithm. |
F |
|
Flash memory | Memory area in which device configuration may be saved; configuration information not stored in the flash memory is lost during a power cycle or when the device is rebooted or reloaded. |
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. |
S |
|
Secure Sockets Layer (SSL) | An application-level protocol enabling secure transactions of data through privacy, authentication, and data integrity. |
Simple Network Management Protocol (SNMP) | An application-level protocol used to monitor and perform basic configuration of network devices. |
Server Port | The user-specified secure TCP port monitored by the Cisco Secure Content Accelerator for secure transaction requests. |
