Appendix A: Glossary

R
real-time streaming protocol	A standard method of transferring audio and video and other time-based media over
(RTSP)	Internet-technology based networks. The protocol is used to stream clips to any RTP-
	based client.
reflect client IP attribute	Enables the sending of the client's IP address instead of the SG's IP address to the
	upstream server. If you are using an application delivery network (ADN), this setting
	is enforced on the concentrator proxy through the Configuration > App. Delivery
	Network > Tunneling tab.
registration	An event that binds the appliance to an account, that is, it creates the Serial#, Account
	association.
remote authentication dial-	Authenticates user identity via passwords for network access.
in user service (RADIUS)
reverse proxy	A proxy that acts as a front-end to a small number of pre-defined servers, typically to
	improve performance. Many clients can use it to access the small number of
	predefined servers.
routing information protocol	Designed to select the fastest route to a destination. RIP support is built into Blue
(RIP)	Coat appliances.
router hops	The number of jumps a packet takes when traversing the Internet.
S
secure shell (SSH)	Also known as Secure Socket Shell. SSH is an interface and protocol that provides
	strong authentication and enables you to securely access a remote computer. Three
	utilities—login, ssh, and scp—comprise SSH. Security via SSH is accomplished using
	a digital certificate and password encryption. Remember that the Blue Coat SG
	appliance requires SSH1. An SG appliance supports a combined maximum of 16
	Telnet and SSH sessions.
serial console	A third-party device that can be connected to one or more Blue Coat appliances.
	Once connected, you can access and configure the appliance through the serial
	console, even when you cannot access the appliance directly.
server certificate categories	The hostname in a server certificate can be categorized by BCWF or another content
	filtering vendor to fit into categories such as banking, finance, sports.
server portals	Doorways that provide controlled access to a Web server or a collection of Web
	servers. You can configure Blue Coat SG appliances to be server portals by mapping a
	set of external URLs onto a set of internal URLs.
server-side transparency	The ability for the server to see client IP addresses, which enables accurate client-
	access records to be kept. When server-side transparency is enabled, the appliance
	retains client IP addresses for all port 80 traffic to and from the SG appliance. In this
	scheme, the client IP address is always revealed to the server.
service attributes	Define the parameters, such as explicit or transparent, cipher suite, and certificate
	verification, that the SG appliance uses for a particular service. .
