Computer Firewall Security Tips - What You Should Know About Firewall
The Internet contains so much information and people can search any information from the comfort of their home. You can search and download software, e-books, ordering books, online ticket booking, doing online banking and so much more.
However, Internet also contains threats that will cost you more than buying a new PC. The hackers can hack into your computer and steal your private and confidential information by using malicious software. If the malicious software gets into your computer, it will attempt to send your private information to the hackers without you knowing.
So, how can we prevent the malicious software from sending our private information? The answer is firewall. Firewall can filter your ingoing and outgoing traffic. Therefore, if any malicious software is trying to send your information to the outside world, it will filter it and your information will stay in your computer safely.
Firewall is a very useful tool and it can take the forms of a router, stand-alone server or software. Some people think that if they have an antivirus installed in their system, they no longer need any extra protection. But without firewall, malicious software can easily send the private information to the hackers.
But how can we test that our firewall is working perfectly? Luckily there is a way to test the firewall. The LeakTest software was created to test if the firewall will be able to block outgoing traffic or not. Shockingly, there are big companies firewalls out there that fail this simple test and they claimed that this test does not prove their firewalls cannot block outgoing traffic.
In my personal opinion, this simple test is very useful to determine if you have a good firewall installed in your system. The LeakTest software is a freeware and you can download it for free. Google it and download and remember to read the instruction before performing the test.
