SIP (Source IP) Address

The source IP address of a frame.

Slave

A VPN Gateway that depends on a master device in the same
cluster for proper configuration.

SNMP (Simple Network Management Protocol)

A network monitoring and control protocol. Data is passed from
SNMP agents, which are hardware and/or software processes
reporting activity in each network device (a VPN Gateway, for
example), to the workstation console (or SNMP manager) used to
oversee the network. The SNMP agents return information in a
MIB (Management Information Base), which is a data structure
that defines what information is obtainable from the device.

SOCKS

A generic, proxy protocol for TCP/IP-based networking
applications. The SOCKS protocol provides a flexible framework
for developing secure communications by easily integrating other
security technologies, e.g. SSL.

SOCKS includes two components, the SOCKS server and
the SOCKS client. The SOCKS server is implemented at the
application layer, while the SOCKS client is implemented between
the application and transport layers. The basic purpose of the
protocol is to enable hosts on one side of a SOCKS server to gain
access to hosts on the other side of a SOCKS server, without
requiring direct IP reachability.

SPort (Source Port)

The source destination port, linking the incoming data to the
correct service. For example, port 80 for HTTP, port 443 for
HTTPS, port 995 for POP3S.

SSH (Secure Shell)

A program to log into another computer over a network, to
execute commands in a remote machine, and to move files from
one machine to another. It provides strong authentication and
secure communications over insecure channels.
