introduction
Firewalls
are computer security systems that protect your office/home PCs or your network
from intruders, hackers & malicious code. Firewalls protect you from
offensive software that may come to reside on your systems or from prying
hackers. In a day and age when online security concerns are the top priority of
the computer users, Firewalls provide you with the necessary safety and
protection.
What exactly are
firewalls?
Firewalls
are software programs or hardware devices that filter the traffic that flows
into you PC or your network through an internet connection. They sift through
the data flow & block that which they deem (based on how & for what you
have tuned the firewall) harmful to your network or computer system.
When
connected to the internet, even a standalone PC or a network of interconnected
computers make easy targets for malicious software & unscrupulous hackers.
A firewall can offer the security that makes you less vulnerable and also
protect your data from being compromised or your computers being taken hostage.
How do they
work?
Firewalls
are setup at every connection to the Internet, therefore subjecting all data
flow to careful monitoring. Firewalls can also be tuned to follow
"rules". These Rules are simply security rules that can be set up by
yourself or by the network administrators to allow traffic to their web
servers, FTP servers, Telnet servers, thereby giving the computer
owners/administrators immense control over the traffic that flows in & out
of their systems or networks.
Rules
will decide who can connect to the internet, what kind of connections can be
made, which or what kind of files can be transmitted in out. Basically all
traffic in & out can be watched and controlled thus giving the firewall
installer a high level of security & protection.
