Installing a firewall on any computer with a broadband
connection is almost mandatory. A permanent, ‘always-on’ broadband
connection means that your computer has a fixed identity on the Internet,
which could be exploited by rogue software programs or viruses.
A firewall basically sits between your computer and the Internet and
acts as a buffer, or safety zone, to protect your computer
from any malicious activity. Firewalls can either be software programs
or separate pieces of computer hardware. Most home users with a single
computer will find that a software firewall is normally sufficient to
meet their needs.
Without effective firewall protection, it is almost inevitable that your
computer will become compromised at some point. A firewall is therefore
a critical element of your home computing set-up. Although
installing a firewall may be a steep learning curve, it is necessary to
understand the importance of having firewall protection if you have a
permanent, 'always-on' broadband Internet connection.
Below are a select few examples from the many firewalls available:
