Abstract:
The Internet has made large amounts of
information available to the average computer
user at home, in business and in education. For
many people, having access to this information
is no longer just an advantage, it is essential. Yet
connecting a private network to the Internet can
expose critical or confidential data to malicious
attack from anywhere in the world. Firewalls
can protect both individual computers and
corporate networks from hostile intrusion from
the Internet, but must be understood to be used
correctly. A personal firewall is an application
which controls network traffic to and from a
computer, permitting or denying
communications based on a security policy.
Personal firewalls are typically designed for
end-users. Personal Firewall is able to control
network traffic by prompting the user. Personal
firewalls may also provide some levels of
intrusion detection, allow the software to
terminate or block connectivity where it suspects
an intrusion is being attempted. This paper is
proposed to implement personal firewall used in
laptops, personal computers and Personal
Digital Assistants (PDA) for personal use.
