what is security clearance for jobs in usa
Security clearance In the United States, a security clearance is an official determination that an individual may access information classified by the United States Government. Security clearances are hierarchical; each level grants the holder access to information in that level and the levels below it. The clearance process requires a background investigation and the signing of a nondisclosure agreement. Access to any particular piece of information requires "need-to-know."[10] In some cases, this requirement is only nominal, as some classified information is widely published on secure networks. In other cases, there is a formal need-to-know determination. In addition to such a determination, Special Access Programs and Sensitive Compartmented Information may require additional investigation and adjudication of the prospective clearance holder.
