The
firewall is a
necessary component in any network installation. Firewalls protect your data
and equipment from unauthorized access.
Spam and
viruses do not attack the
firewall;
however, every packet of data that is put before the
firewall must be
analyzed to determine what to do with the data. This analysis of unsolicited
messages can slow down the overall performance of the device and reduce the
speed at which you can communicate on the internet.
