According to CNet, Apple has submitted Mac OS X for an independant security evaluation.
The testing, being done as part of the U.S. government's National Information Assurance Partnership, will evaluate Mac OS X and Mac OS X Server on a series of common criteria used by a number of countries to evaluate the security features of various technologies. The evaluation allows governments and businesses to compare the relative security features of different products.
Submitting the operating system for testing could help give the Mac more clout in government circles, said Tom Goguen, director of worldwide product marketing for Apple's server software unit.
