Discussions of network structure and security frequently depend on network
diagrams. This guide uses the following set of icons in all of its diagrams.
Router2
This icon represents a router. Each line
connected to a router icon represents a
network interface on that router. Each router
is presumed to have an administrative console
line connection, which is not shown.
Server
Workstation
Computers on the network are represented
with one of these two icons.
Small LAN
12.34.56.0/24
A local-area network (LAN) segment, such as
an Ethernet, is represented by a horizontal or
vertical bus, with several connections.
Network
This icon represents a LAN or a wide-area
network over which routers communicate.
Such networks normally include other routers,
and may include bridges, switches, link
encrypters, and other network hardware.
