Answer / raj

The PIX Firewall protects an inside network from
unauthorized access by users on an outside network, such as
the public Internet. Most PIX Firewall models can
optionally protect one or more perimeter networks, also
known as demilitarized zones (DMZs). Access to the
perimeter network is typically less restricted than access
to the inside network, but more restricted than access to
the outside network. Connections between the inside,
outside, and perimeter networks are controlled by the PIX
Firewall.

All PIX Firewalls provide at least two interfaces, which by
default, are called outside and inside, and are assigned a
security level of 0 and 100, respectively.
