3 Levels of Security Clearance

August 18, 2008

Classification Levels

National security information that requires protection against unauthorized disclosure are classified at one of the following three levels.

 

 


Top Secret Clearance
Top Secret is applied to information that reasonably could be expected to cause exceptionally grave damage to the national security if disclosed to unauthorized sources.

This level needs to be reinvestigated every 5 years.

Secret Clearance
Secret is applied to information that reasonably could be expected to cause serious damage to the national security if disclosed to unauthorized sources.

This level is reinvestigated every 10 years.

Confidential Clearance
Confidential is applied to information that reasonably could be expected to cause damage to the national security if disclosed to unauthorized sources. The vast majority of military personnel are given this very basic level of clearance.

This level needs to be reinvestigated every 15 years.

Clearance Reinvestigation
Reinvestigations are more important than the original investigation because those individuals who have held clearances longer are more likely to be working with increasingly critical information.

    Security is only as good as it's funding,and updating.We will always have holes in National security softwares.Thats how you catch the crinimals.They try to outsmart the system, that lets them in to be loged.If someone is smart enough to hack,then they should get real jobs protecting systems from hackers ,and developing software to safeguard transactions.Beats prision,or not being able to use a touch tone telephone, and a computer till your 18th birthday. =:( The only time a hacker does any good, is when he(s) exposes illegal operations ,that the law will sort out when proven in a court.And may God have mercy on his phone bill.

    Airport security staff (administered by TSA) undergo a separate protocol - it is similar to an L Type clearance (SECRET).

    I went through a full background investigation and was granted a top secrect clearance in December 2007 but changed jobs soon after and the clearance was used only to obtain a position as a contractor. Will the status of the clearance remain or will a new background check be required if I apply for a position requiring a top secret clearance?

    Would working for FEMA for 90 days following hurricane Katrina give me one of these classifications that would still be valid after 3 years?
