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.
