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.
What is an Operational Requirement Specification
An OPRS, is a document used to define the application of security elements.
It is used to ensure that the correct equipment is being selected to meet the security objectives.
It curtails the over application of security elements as each element is specifically identified as to its type, purpose and security objective.
The OPRS is the client’s best friend - if used properly - as it prevents equipment being over specified, thus costing the client more money.
