OS to know.

["John Williams" <ibmros () hotmail com>]

I am a graduate student at George Mason University obtaining my MS in 
Information Security and Assurance. What operating system is used more for 
security administration in the private sector versus the government sector? 
Pretty much I would like to know what operating system I should focus on if 
I wanted to pursue a government career in security or if I wanted to purse a 
career in the private sector. Thanks.
