Firewalls work on a set of rules to determine which inbound and outbound connections are authorized. If
your computer is preintalled with a rewall program, it helps protect against computer Internet security
threats, unauthorized access, intrusions, and Internet attacks. It also protects your privacy. For more
information about how to use the rewall program, refer to the help system of your rewall program.
The Windows operating system preinstalled on your computer provides the Windows Firewall. For details on
using the Windows Firewall, refer to “Help and Support” on page 111
