Browser – The Gateway to Internet

browser security testBrowsers are like windows, through which your computer interacts with the outside world. It is the gateway, through which you can access the vast information available on the Internet.

But at the same time, they are also the pathways, through which malware can sneak into your computers. They can take the exploit the security holes in your browsers to infect your computer. For any robust PC Security plan, it is important to plug these browser security holes.

How to Plug Security Holes in Your Browsers

There is one simple trick, nothing complex. Just remember to update your browser with the latest release. Most of the browsers like Firefox and Google Chrome have an automatic software update feature and they notify you as soon as a new stable release version is available for download. You just have to listen to them and keep on updating.

Internet Explorer updates are released by Microsoft alongwith the Windows Updates. You just have to keep the Automatic Windows Update ON. But for some of the browsers like Opera, you might have to keep a eye yourself on the availability of the new release and download the new version afresh.

How to Test Your Browser Security

I just found one useful online Browser Security Test, which is absolutely free to use. Nothing complex, just head on to the website http://bcheck.scanit.be/bcheck/index.php. It will identify your browser details. Click on the Start Security Test, and your browser will be grilled with some rigorous testing. This tool is available for both of the popular Internet browsers, Internet Explorer and Firefox.

It may not be making much sense to you, but if you are interested, following is the list of the security tests performed by it.
