Multiple operating systems to enhance security How do you comment about the security benefits of such a setup? Drive C: Empty or dummy OS Drive D: Windows XP Pro SP3 (for normal usage) Drive E: Windows XP Pro SP3 (dedicated for online banking, shopping and the like) Security benefits: Non-default drive letter: Minor benefit but you are *slightly* less likely to be hacked if Windows resides on a drive other than C since the vast majority of people install Windows to their C drive. I know it's minor benefit but it doesn't hurt to do Dummy OS for easy target: You may optionally install a dummy OS. Its purpose is to sit and wait for infection. It's to give a false target for the hackers to attack. Dedicated Windows for mission-critical tasks: You only boot from this system to perform online banking, shopping and the like. Login --> Go to bank website --> Do transaction --> Log off. It's next to impossible to get infected in this case. You can install no security software or just a firewall in this dedicated Windows. This setup is much better than the expensive security setup with anti-virus, anti-trojan, anti-spyware, HIPS etc. Still they can't help getting infected by the ever-changing malware technology. This setup is 99.99% safe against new unknown malware, and even personalized/rare malware, unless this setup becomes so popular and malware writers start to write virus to infect multi-operating systems. What do you think? How true is it?
