About computer connections
Computer connections are the connections that you create
between other computers on any network and yours. You can
add, edit, and remove IP addresses on the
Networks list. These IP
addresses are associated with networks for which you want to
assign a level of trust when connecting to your computer:
Trusted, Standard, and Public.
Level Description
Trusted
Firewall allows traffic from an IP to reach your computer
through any port. Activity between the computer
associated with a Trusted IP address and your computer is
not filtered or analyzed by Firewall. By default, the first
private network that Firewall finds is listed as Trusted in
the
Networks
list. An example of a Trusted network is a
computer or computers in your local or home network.
Standard
Firewall controls traffic from an IP (but not from any other
computer in that network) when it connects to your
computer, and allows or blocks it according to the rules in
the
System Services
list. Firewall logs traffic and
generates event alerts from Standard IP addresses. An
example of a Standard network is a computer or
computers in a corporate network.
Public
Firewall controls traffic from a public network according to
the rules in the
System Services
list. An example of
Public is an Internet network in a cafe, hotel, or airport.
When allowing a connection, make sure that the computer that
you trust is safe. If a trusted computer is infected with a worm or
other mechanism, your computer can be vulnerable to infection.
Also, McAfee recommends that the computer you trust is
protected by a firewall and an up-to-date antivirus program.
