What is a firewall?
A firewall is an essential piece of security
software that monitors all incoming and
outgoing traffic going through your
network, checking for hackers, malware,
unauthorized outgoing information, or
anything that might put you or your PC at
risk. Firewalls are often the first line of
defense when protecting your data.
Why use a firewall?
Hackers can use Trojan viruses and
keylogging software to access your
computer and steal your personal data such
as your history, passwords, and banking
details by recording your sessions and
keeping track of your keystrokes. They can
also harness the power of your computer to
run illicit activities without your knowledge
(yes, your PC can be a part of the problem –
strange, but true).
What does a firewall do?
Cyber criminals can use any internet
connection or Wi-Fi network as an entry
point into your computer. Firewalls block all
unauthorized connections to your computer
(including those of hackers who are trying
to steal your data) and even let you select
which programs can access the internet so
that you’re never connected unknowingly.
