Common ground of physical and information security
Physical information security is the intersection, the common ground between physical security and information security. It primarily concerns the protection of tangible information-related assets such as computer systems and storage media against physical, real-world threats such as unauthorized physical access, theft, fire and flood. It typically involves physical controls such as protective barriers and locks, uninterruptible power supplies, and shredders. Information security controls in the physical domain complement those in the logical domain, and procedural or administrative controls.
Status granted to individuals allowing them access to classified information or to restricted areas
A security clearance is a status granted to individuals allowing them access to classified information or to restricted areas, after completion of a thorough background check. The term security clearance is also sometimes used in private organizations that have a formal process to vet employees for access to sensitive information. A clearance by itself is normally not sufficient to gain access; the organization must also determine that the cleared individual needs to know specific information. No individual is supposed to be granted automatic access to classified information solely because of rank, position, or a security clearance.
