Defence in depth for the home

Posted on: March 25, 2010

‘Defence in depth’. That is what the commercial security world calls having multiple layers of security to protect you in case one fails.

Simply put, your home computer needs to have multiple layers of defences including an up to date browser like Firefox, have Anti Virus software that works, run Windows Update every month and update all your applications at least weekly, as a minimum. Sounds like hard work, no one interested in your computer? Don’t be a muppet!

If your computer is hacked then you could be storing child porn, terrorist training material, or your computer could be used to send spam. Assuming that you never entered any personal or financial information, else that would have been stolen as well, the worst case scenario is that your home gets raided as part of the war on terror and computers seized…

No one can guarantee perfect Internet computer security unless you unplug the Internet.

A recent hacking contest showed that ALL major browsers on the Internet can have security issues including Safari on Macs, iPhones, Windows 7,  and both Internet Explorer 8 and Firefox on any computer. So next time you click on a link sent to you, visit dubious websites, or download a file from the Internet, be sure of your defences and make sure they are deep!
