Blue Coat Systems SGOS Version 5.2.2 manual Volume 9: Managing the Blue Coat SG Appliance

Volume 9: Managing the Blue Coat SG Appliance

destination objects	Used in Visual Policy Manager. These are the objects that define the target location of
	an entry type.
detect protocol attribute	Detects the protocol being used. Protocols that can be detected include: HTTP, P2P
	(eDonkey, BitTorrent, FastTrack, Gnutella), SSL, and Endpoint Mapper.
diagnostic reporting	Found in the Statistics pane, the Diagnostics tab allows you to control whether Daily
	Heartbeats and/or Blue Coat Monitoring are enabled or disabled.
directives	Commands used in installable lists to configure forwarding and SOCKS gateway.
DNS access	A policy layer that determines how the SG appliance processes DNS requests.
domain name system (DNS)	An Internet service that translates domain names into IP addresses. See also private
	DNS or public DNS.
dynamic bypass	Provides a maintenance-free method for improving performance of the SG appliance
	by automatically compiling a list of requested URLs that return various kinds of
	errors.
dynamic real-time rating	Used in conjunction with the Blue Coat Web Filter (BCWF), DRTR (also known as
(DRTR)	dynamic categorization) provides real-time analysis and content categorization of
	requested Web pages to solve the problem of new and previously unknown
	uncategorized URLs—those not in the database. When a user requests a URL that has
	not already been categorized by the BCWF database (for example, a brand new Web
	site), the SG appliance dynamic categorization service analyzes elements of the
	requested content and assigns a category or categories. The dynamic service is
	consulted only when the installed BCWF database does not contain category
	information for an object.
E
early intercept attribute	Controls whether the proxy responds to client TCP connection requests before
	connecting to the upstream server. When early intercept is disabled, the proxy delays
	responding to the client until after it has attempted to contact the server.
ELFF-compatible format	A log type defined by the W3C that is general enough to be used with any protocol.
emulated certificates	Certificates that are presented to the user by SG appliance when intercepting HTTPS
	requests. Blue Coat emulates the certificate from the server and signs it, copying the
	subjectName and expiration. The original certificate is used between the SG
	appliance and the server.
encrypted log	A log is encrypted using an external certificate associated with a private key.
	Encrypted logs can only be decrypted by someone with access to the private key. The
	private key is not accessible to the SG appliance.
EULA	End user license agreement.
event logging	Allows you to specify the types of system events logged, the size of the event log, and
	to configure Syslog monitoring. The appliance can also notify you by email if an
	event is logged. See also access logging.
