One of the constituents of the state security is protecting information against unauthorized disclosure which would or could be harmful for the Polish state, or would be adverse for its interests, regardless of the form and the way they are expressed. Being classified, such information may be made available only to those who guarantee secrecy, and only to the extent necessary to perform their job or service on a given position, or perform duties entrusted. A screening, being an element of personal security, can prove whether a person guarantees secrecy or not. This procedure is to determine if, after obtaining access to classified information, a person tested would constitute doubts as far as the existence of unauthorized disclosure of classified information is concerned. A security clearance providing access to classified information has to be issued after a thorough examination, and only to the person guaranteeing full secrecy.
