What is a Qualitative Security Survey?
A qualitative analysis is more suitable when evaluating lower security applications. These facilities will have lower consequence loss assets and so will be better able to withstand loss or damage of an asset.
Some examples might include retail stores, apartment buildings, small businesses, and restaurants.
What is a Quantitative Security Survey ?
A rigorous quantitative analysis is required for protection of assets with unacceptably high consequence of loss, even if the probability of an adversary attack is low. This is a characteristic of high security systems typically found at pharmaceutical facilities, nuclear power plants, prisons, government and military installations, plus some museums, refineries, utilities, airports, telecommunications hubs and large industrial complexes. In each of these cases the loss of or damage to at least some of these assets can have high consequences.
