Computer Security and Layers just like Shrek's onions

Security is focused on creating layers. An obstacle course for attackers which means they have to hop and climb over and hopefully will give up and attack another computer, making it another person’s problem. Minimising risk is an important goal in achieving a secure system. It is important that whilst creating a secure system the system is not put into a lock down state. This creates a system with no functionality or usability and by definition not a secure system. It is important that users of computer systems stay informed and are aware of how to protect there systems. Microsoft’s new operating system Vista has promised new and exciting features, hopefully it will not be a repeat of Windows XP and its security problems and we can work with secure, functional and easy to use systems.
