Summary

Firewalls do not solve every home network security issue. They are a critical step for security, but they need to be complemented with the other steps in this book (including antivirus and antispyware/adware).

Also, do not expect a firewall to catch every hack or intrusion attempt. Firewalls are pretty good at blocking today's known hacks. However, crafty folks as the hackers are, they can find new ways around firewalls.

View having appropriate firewalls in your home network as significantly raising the barrier against intruders so that they move on to easier targets.
