Generally speaking, a computer firewall is a kind of
software program that works by preventing unauthorized access from or to a
private network. Firewalls are considered as tools that could help enhance computer
security including those that are connected to a network like the internet
or LAN. Firewalls are an important part of an extensive network security
framework.
A firewall will isolate the computer from the internet through
the use of a wall of code that check every individual packet of data when it
arrives at either firewall’s sides – outbound or inbound from your computer –
know if it will be blocked or allowed to pass.
Firewalls can further improve the security of your
computer by allowing granular control over what kinds of system processes
and functions have access to the networking resources. Firewalls could use
different kinds of signatures as well as host conditions to deny or allow
traffic. Even though they seem complicated, firewalls are quite easy to
install, setup, as well as operate.
Many people believe that a firewall is a device that needs
to be installed on a network and it will control the traffic that moves through
the network segment.
But, it is also possible to have firewalls that are host
based. This could be done on the units themselves, like with ICF or Internet
Connection Firewall. Generally, the work of these two firewalls is the same.
They prevent intrusion and offer a strong way of accessing control policy. In
simple terms, firewalls are nothing but a unit that protects your computer.
What Is The Job Of A Firewall?
Firewalls do the following things:
- Validate access
- Protect resources
- Control and manage network traffic
- Report and record events
- Work as an intermediary
What And Why You Need A Personal Firewall?
It is crucial to know why you need a firewall
and how it can help you secure computing. We have to understand the objective
of information security since it helps us to know how a firewall will deal with
those needs.
With today’s high speed Internet Access, you connect your
computer electronically to a huge network over which, unless you’ve got a personal firewall installed,
you will have restricted control and from which you will have restricted
protection. Until lately, unless you have worked for a company that offers high
speed internet access.
But just like anything, there are drawbacks to high speed
internet connection. But there is an irony to all these. The feature that makes
it attractive is also the reason that it’s vulnerable. It’s like connecting to
the internet through a highspeed internet connection is just like leaving your house’s front door open
and worse, unlocked. It’s because high speed internet connection possesses
these following features. It has a constant IP, a high speed access, and an
active connection.
Protect Yourself With A Personal Firewall
Now that you already have an idea that you’re extremely
vulnerable when you are online on a high speed internet connection, what should
you do next? You have to learn how to defend your
computer and yourself.
You need a firewall when you surf the internet when you are
at home and you are using an always on broadband connection. You connect to the
internet through a public WiFi network in an airport, café, or park. You run a
home network that needs to remain separated from the internet. You want to
remain updated about when a program on your computer tries to connect to the
internet. Most personal
firewalls can be configured so you can easily make security policies that
are suitable for your personal needs.
