Posted on April 17, 2009. Filed under: Computer, Security, Tutorials, Web | Tags: , , , , , , , |


       Today, i read an article on my friend Rick’s (whatsonmypc ) blog about “Free layers of protection”. It somehow inspired me to write about how to check the security of your machine on Internet. So now, I’m starting an Internet security Test Series which cover all test to check your computer security on internet one by one, which helps you to know how much safe you are.

              In Internet Security Series-I  today we test firewall

         Basically, a firewall is a barrier to keep destructive forces away from your property/computer. In fact, that’s why its called a firewall. Its job is similar to a physical firewall that keeps a fire from spreading from one area to the next.

       So, this test will check your computer for ports that are commonly left open. Open ports could allow your computer to be compromised. This firewall test will also check for open ports known to be used by Viruses and Trojans.

      

       Are you ready to test your firewall?

    1. if yes,then Click Here

       

    2. Scroll down and you find a heading firewall testing -get started. In a box enter your IP which is written on that page and enter.

                   

    3.  Here you can choose which type of security scan you want to perform:

  • Standard Security Scan– This is for most internet users. This security scan checks commonly used ports as well as test for known ports used by trojan and virus programs.
  • Ranged Security Scan – This scan allows you to test a range of ports to help determine services running on all 65,535 ports. This is for network administrators and security professionals .
  • Advanced Security Scan– This gives you option to enter the ports you want scanned. Simply separate them with a comma such as 23,80,27374. For a UDP port scan ,simply add UDP, to the list of ports, for example: UDP,20,23.

   

      4. After Select anyone of the above three click start scan. After few seconds this will display your result.

      Now you can see how powerful and secure firewall you have ..
