Apple has submitted its Mac OS X operating system for an independent security evaluation.

The testing will be carried out as part of the US government's National Information Assurance Partnership (NIAP). It will evaluate Mac OS X and Mac OS X Server on a series of criteria common to a number of countries. Testing will identify various technologies' security features, which will be compared by governments and businesses, NIAP claims.

Tom Goguen, director of worldwide product marketing for Apple's server-software unit, said agreeing to have the system tested would lend Macs more weight within the government as Unix-based operating systems are widely used in government systems, according to Cnet. Goguen said: "It will help us get more exposure."
