[1] It typically involves preventing or reducing the probability of unauthorized or inappropriate access to data or the unlawful use, disclosure, disruption, deletion, corruption, modification, inspection, recording, or devaluation of information.
The McCumber Cube. The McCumber Cube is a model for establishing and evaluating information security (information assurance) programs.This security model, created in 1991 by John McCumber, is depicted as a three-dimensional Rubik's Cube-like grid.
The source reliability is rated between A (history of complete reliability) to E (history of invalid information), with F for source without sufficient history to establish reliability level. The information content is rated between 1 (confirmed) to 5 (improbable), with 6 for information whose reliability can not be evaluated.
The intersection of security risk and laws that set standards of care is where data liability are defined. A handful of databases are emerging to help risk managers research laws that define liability at the country, province/state, and local levels. In these control sets, compliance with relevant laws are the actual risk mitigators.
The CIA, for example, is more likely to obtain HUMINT on terrorists than the very limited foreign resources of the Department of Homeland Security (DHS) or the Federal Bureau of Investigation (FBI). The DHS, like the military, is seen principally as a consumer of national intelligence, but its border and transportation security functions also ...
