†(Personal communication, Rich Dymalski (email)) Both the logical and physical means that will insure that information is protected. 'Logical Security' is an intangible process that identifies, authenticates, authorizes, protects, and provides access control over programs and data. A password is an example of logical security for data stored or transmitted. 'Physical Security' refers to material factors (facility, environment, communication wiring, devices, etc.). Anchoring desktop computers with locks is an example of a physical security item.
