En undersökning i datasäkerhet för hemanvändare - Är det nödvändigt att använda brandvägg?
The emphasize of this study is to evaluate security issues for home users
having a personal computer connected to the Internet. It focus on the usage of
advantages and disadvantages when using a firewall while connected to the
Internet.
The hypothesis is that it gives a better protection to install and use a
firewall compared not to do so, due to security flaws in the operating system.
The prediction was tested on a home user's personal computer. The testwork was
divided into two major tests, each of them performed with, respectively
without, a firewall. These major tests were divided into five smaller semi
tests. The first semitest without a firewall suffered from a virus or worm
attack resulting in loss of data and log files. During the other tests no
successful intrusion was detected. The conclusion of the study is that usage of
a standard configured firewall provides a better protection for home users than
not to use a firewall; and it's beneficial to update the operating system and
other programs with security updates as soon as possible when they appear.
