what is a government security clearance ?

Answer 1

Security clearance descriptors often appear in employment advertisements, as employers generally prefer to hire people who are already cleared to access classified information at the level needed for a particular job or contract.

Due to the nature of security classifications and clearances, often people incorrectly identify their clearances by a combination of actual clearance level, additional access controls, caveats, and the organization who granted them clearance. In addition, different organizations within the Federal government use different terminology and lettering, as is discussed below.

Some items on are based on a list compiled by a nonauthoritative source on the Internet. Items marked "*" are defined in the 2006 U.S. Government's National Industrial Security Program Operating Manual (NISPOM) p. 14 ff [1] Any combination of the SI, SI-ECI-*, TK, B, G, HCS letters can be used.

Information is classified at 3 levels. For general access to this information, the Cognizant Security Authority ( Generally, the DoD), grants collateral clearances at the level:

C - Confidential *
S - Secret *
TS - Top Secret (DoE has the Q clearance which is equivalent) *
On top of classification, the Government also has special access control systems for certain information, in which access is determined by need-to-know, and which may have increased investigative requirements before access is granted:

SAP - Special Access Program *
SCI - Sensitive Compartmented Information *
SI
TK
G
HCS
Some catagories of information, while possibly but not necessarily needing special access control, by their nature may require extra security education, special handling procedures, et cetera. These are known as caveats:

COMSEC - Communications Security *
CNWDI - Critical Nuclear Weapon Design Information *
NOFORN - Not Releasable to Foreign Nationals (access restricted to U.S. citizens) *
WNINTEL - Warning Notice - Intelligence Sources and Methods Involved [2]
CRYPTO - Cryptographic *
Prior to being granted any clearances or accesses, A person is investigated by the Government. Depending on the level of clearance and access the person needs, the Government undertakes one of the following investigations:

LAC - Local Agency Check
NAC - National Agency Check
NACLC (National Agency Check with Local Agency Check and Credit Check) *
SSBI - Single Scope Background Investigation *
SBPR - SSBI Periodic Reinvestigation
SBI - Special Background Investigation
EBI - Extended Background Investigation
Certain accesses require one to undertake one ore more polygraphs:

Polygraph - Counterintelligence Scope (CI, CI Poly)
Polygraph - Full Scope / Lifestyle (FS, LS, Lifestyle Poly)

The FBI does an extensive search on you and your background to look for any criminal records, terrorist affiliations, etc....Clearances have different levels i.e. classified, secret, top secret....and even if you have a top secret clearance you still must have a "need to know" before you can get involved or read document...Clearances are required for certain military jobs, working at the pentagon, white house, with any foreign ambassadors, to be member of the house and/or senate, any important job with the government, and I'm sure a lot of other things, like working for NASA. Hope this answers your question.
