Question:
What is "protected" information?
Answer:
Information is "protected" if its disclosure could harm interests other than the "national interest."
There are three levels of protected information:
1) Protected C (extremely sensitive): applies to the very limited amount of information that, if compromised, could reasonably be expected to cause extremely grave injury outside the national interest, for example, loss of life.
2) Protected B (particularly sensitive): applies to information that, if compromised, could reasonably be expected to cause serious injury outside the national interest, for example, loss of reputation or competitive advantage.
3) Protected A (low-sensitive): applies to information that, if compromised, could reasonably be expected to cause injury outside the national interest, for example, disclosure of exact salary figures.
