Create new firewall rules
Norton Personal Firewall includes Program Control, which helps you create
firewall rules as you use the Internet.
There are four ways to create firewall rules with Program Control:
Enable Automatic Program Control
When Automatic Program Control is active, Norton Personal Firewall can
automatically configure Internet access settings for programs the first time
that they run. Automatic Program Control only configures Internet access
for the versions of programs that Symantec has identified as safe.
If an unknown program or an unknown version of a known program
attempts to access the Internet, Norton Personal Firewall warns the user.
The user can then choose to allow or block Internet access for the program.
See “Keeping
current with
LiveUpdate” on
page 53.
Symantec regularly updates the list of recognized programs. You should
run LiveUpdate regularly to ensure that your list is up-to-date.
