Volume 9: Managing the Blue Coat SG Appliance

SG appliance

A Blue Coat security and cache box that can help manage security and content on a

 

network.

sibling class (bandwidth

A bandwidth class with the same parent class as another class.

gain)

 

simple network

The standard operations and maintenance protocol for the Internet. It uses MIBs,

management protocol

created or customized by Blue Coat, to handle (needs completion).

(SNMP)

 

simulated live

Used in streaming. Defines playback of one or more video-on-demand files as a

 

scheduled live event, which begins at a specified time. The content can be looped

 

multiple times, or scheduled to start at multiple start times throughout the day.

SmartReporter log type

A proprietary ELFF log type that is compatible with the SmartFilter SmartReporter

 

tool.

SOCKS

A proxy protocol for TCP/IP-based networking applications that allows users

 

transparent access across the firewall. If you are using a SOCKS server for the

 

primary or alternate forwarding gateway, you must specify the appliance’s ID for the

 

identification protocol used by the SOCKS gateway. The machine ID should be

 

configured to be the same as the appliance’s name.

SOCKS proxy

A generic way to proxy TCP and UDP protocols. The SG appliance supports both

 

SOCKSv4/4a and SOCKSv5; however, because of increased username and password

 

authentication capabilities and compression support, Blue Coat recommends that

 

you use SOCKS v5.

splash page

Custom message page that displays the first time you start the client browser.

split proxy

Employs co-operative processing at the branch and the core to implement

 

functionality that is not possible in a standalone proxy. Examples of split proxies

 

include:

 

• Mapi Proxy

 

• SSL Proxy

SQUID-compatible format

A log type that was designed for cache statistics and is compatible with Blue Coat

 

products.

squid-native log format

The Squid-compatible format contains one line for each request.

SSL authentication

Ensures that communication is with “trusted” sites only. Requires a certificate issued

 

by a trusted third party (Certificate Authority).

SSL interception

Decrypting SSL connections.

SSL proxy

A proxy that can be used for any SSL traffic (HTTPS or not), in either forward or

 

reverse proxy mode.

static route

A manually-configured route that specifies the transmission path a packet must

 

follow, based on the packet’s destination address. A static route specifies a

 

transmission path to another network.
