The US spooks advice to businesses to adopt Vista or Windows 7, have upset all Linux enthusiasts. Though the suggestion is made considering the security factors, Linux has unfortunately failed to capture their attention.

Businesses are asked to go for Windows 7 and Vista OS, as these operating systems claim to provide the necessary security. Both of these OS are listed in the best practices sheet of NSA. They did mention few other OS including OS-X. The one OS that did not get any consideration from NSA is Linux.

The surprising factor is that, though NSA has seen supporting proprietary software, it has neglected Linux completely.

When compared to the previous Windows workstation operating systems including XP, Windows 7 and Vista offer the necessary security enhancements. Since these security features are default, they offer complete protection against the attack of vectors. The one advice NSA gives to the old Windows XP users is to upgrade their machines and use Windows 7 or Vista.

A fact worth mentioning here is that, unlike Vista or Windows 7, Linux can run on older machines. NSA should have suggested a better alternative OS like Linux. Businesses and firms are advised to prefer Mac OS X system for automatic checking of updates. Once the user is informed about an available update, it should be installed along with confidential credentials. It also asked the users to update Apple's iPad.

All through the best practices sheet, NSA has been supporting proprietary software and has avoided mentioning Linux anywhere which has disappointed all Linux users.
