I recently read a really good and comprehensive blog post from the Windows 8 team regarding security. The article discusses current security approaches and weaknesses. It also overviews common ways to compromise user's credentials on-line and the difficulties of password management. I believe that is a good read for every body and I believe important for power users to spread the word and help casual users to enhance the security over the Internet presences and different devices used on the daily digital routines.
The second part of the article talks about the Windows 8 enhancements regarding security. Handy applications to help users to keep complex and more secure passwords and on-line identities and how Windows 8 provides clever and alternative login mechanisms both for home and corporate users.
Check it out. I'm sure it will be helpful.
