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.
Windows application with SOCKS support. When installed on a
user's computer, transparent access (not through the Portal page)
to intranet applications is enabled.
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.
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.
A utility used to identify the route used for station-to-station
connectivity across the network.
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 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.
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.
