Windows seems to be taking security billions of dollars more serious. This is very exciting. I like Windows 2000/XP but the security is a major conscern. While I don't think Vista will be able to beat up on Unix, Its great that it will be more secure.
Some of Windows Vista's Security Features include:
Least-Priviledge User. Previous implementations of Windows are shipped out with no default security features. This is the reason most people surf with an Admin account. Vista will have User Account Protection which will restrict common users to the following:
Laptop users will be able to set a WEP key to attach to a home wireless network
Users will be able to install printer drivers
Users will be able to download and install updates
VPN and dial-up connections can be created and established
Running most applications
Built in Anti-Virus and Firewall. Windows Vista will have the ability to clean virus from the system. So there may be less of a need for tools such as Adaware and Hijackthis. Although I suspect some third party tools will still be necessary.
The best thing I've read so far about the comming Vista security is the principles behind the Vista design:
According to Debra Shinder's article at WindowSecurity.com,
Last week at the MVP global summit in Redmond, I had the opportunity to hear from a number of Microsoft insiders, the guys who actually wrote the code, about their goals and philosophy in creating the new OS and included components such as Internet Explorer 7.0. I was encouraged by what I heard: defense in depth was a concept that kept coming up over and over again. Multi-layered security is the only way to provide real protection, and MS’s commitment to making fundamental changes in the architecture to support that type of protection will give Vista a big security edge over older Windows operating systems.
