Blue Coat Systems Blue Coat Systems SG Appliance, SGOS Version 5.2.2 manual Appendix A: Glossary

Appendix A: Glossary

issuer keyring	The keyring used by the SG appliance to sign emulated certificates. The keyring is
	configured on the appliance and managed through policy.
L
licensable component (LC)	(Software) A subcomponent of a license; it is an option that enables or disables a
	specific feature.
license	Provides both the right and the ability to use certain software functions within an AV
	(or SG) appliance. The license key defines and controls the license, which is owned
	by an account.
listener	The service that is listening on a specific port. A listener can be identified by any
	destination IP/subnet and port range. Multiple listeners can be added to each
	service.
live content	Also called live broadcast. Used in streaming, it indicates that the content is being
	delivered fresh.
LKF	License key file.
load balancing	A way to share traffic requests among multiple upstream systems or multiple IP
	addresses on a single host.
local bypass list	A list you create and maintain on your network. You can use a local bypass list alone
	or in conjunction with a central bypass list. See bypass list.
local policy file	Written by enterprises (as opposed to the central policy file written by Blue Coat);
	used to create company- and department-specific advanced policies written in the
	Blue Coat Policy Language (CPL).
log facility	A separate log that contains a single logical file and supports a single log format. It
	also contains the file’s configuration and upload schedule information as well as
	other configurable information such as how often to rotate (switch to a new log) the
	logs at the destination, any passwords needed, and the point at which the facility can
	be uploaded.
log format	The type of log that is used: NCSA/Common, SQUID, ELFF, SurfControl, or
	Websense.
	The proprietary log types each have a corresponding pre-defined log format that has
	been set up to produce exactly that type of log (these logs cannot be edited). In
	addition, a number of other ELFF type log formats are also pre-defined (im, main,
	p2p, ssl, streaming). These can be edited, but they start out with a useful set of log
	fields for logging particular protocols understood by the SG appliance. It is also
	possible to create new log formats of type ELFF or Custom which can contain any
	desired combination of log fields.
log tail	The access log tail shows the log entries as they get logged. With high traffic on the
	SG appliance, not all access log entries are necessarily displayed. However, you can
	view all access log information after uploading the log.
