SSL (Secure Sockets Layer) Protocol

The SSL protocol is the leading security protocol on the Internet. It runs above the TCP/IP protocol and below higher-level protocols such as HTTP or IMAP. SSL uses TCP/IP on behalf of the higher-level protocols and, in the process, allows an SSL-enabled server to authenticate itself to an SSL-enabled client.

SSL VPN client

Windows application with SOCKS support. When installed on a user’s computer, transparent access (not through the Portal page) to intranet applications is enabled.

STP (Spanning Tree Protocol)

An algorithm used in transparent bridges that dynamically determines the best path from source to destination. It avoids bridge loops (two or more paths linking one segment to another), which can cause the bridges to misinterpret results. The algorithm creates a hierarchical "tree" that "spans" the entire network including all switches. It determines all redundant paths and makes only one of them active at any given time.

TLS (Transport Layer Security)

The TLS protocol provides communications privacy over the Internet. The protocol allows client/server applications to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.

Traceroute

A utility used to identify the route used for station-to-station connectivity across the network.

Trap

If a trap is defined in the MIB, a trap message is sent from the SNMP agent to the SNMP manager when the trap is triggered. A trap can for example define a hardware failure in a monitored device.

Tunnel Guard

Tunnel Guard is an application that maintains checks that the required components (executables, DLLs, configuration files, etc.) are installed and active on the remote user’s machine.

URI (Uniform Resource Identifier)

The addressing technology from which URLs are created. Technically, URLs such as HTTP:// and FTP:// are specific subsets of URIs, although the term URL is mostly heard.
