A Risk Assessment Methodology (RAM)

for Physical Security

Violence, vandalism, and terrorism are prevalent in the world today. Managers and decision-makers need to have a reliable way of estimating risk to help them choose much protection is needed in their facility. A risk assessment method has been sophisticated by Sandia National Laboratories to assess risk at various types of services including US Mints and federal dams. The strategy is based on the standard risk equation:

Risk sama dengan PA * (1 - PE) 2. C,

PENNSYLVANIA is the probability of adversary attack,

PE can be security system efficiency,

1 - PE is definitely adversary achievement, and

C is result of reduction to the harm.

The process commences with a characterization of the facility including recognition of the undesired events and the respective essential assets. Guidance for defining a design basis threat is included, as well as for using the definition of the threat to estimate the probability of adversary harm at a certain facility. Relative values of consequence will be estimated. Strategies are also included for estimating the effectiveness of the safety system against the adversary assault. Finally, risk is calculated. In the event that the cost of risk is usually deemed to get unacceptable (too high), the methodology address a process to get identifying and evaluating security system upgrades in order to reduce risk.

Be aware: Each crucial infrastructure (CI) follows a RAM process developed specifically for that CI. This white colored paper gives a general discourse on the MEMORY approach and address the differences between the distinct RAMs.


Analysis Methodology

An evaluation methodology has become used to measure the vulnerability of physical safety systems to get facilities. Number 1 describes the purchase and sequence of the several basic actions of the strategy. 1 . Center Characterization

A basic step in security alarm analysis is to characterize the facility operating states and conditions. This task requires having a thorough explanation of the facility itself (the location of the internet site boundary, building locations, floor plans, and access points). A description in the processes in the facility is also required, as well as identification of any existing physical protection features. This information can be obtained by several sources, including center design plans, process points, safety analysis reports, environmental impact assertions, and site surveys. Physique 1 . Measures in the Analysis Methodology

2 . Undesired Events/Critical Assets Id

Undesired Events- The unwanted events has to be established. Unwanted events result in undesired outcomes. Undesired situations are site-specific and have unfavorable impacts upon public health and safety, the surroundings, assets, quest, and promotion.

Critical Assets- The attacker could cause every undesired function to occur in a number of ways. An organized approach is necessary to identify crucial components to get prevention in the undesired events. A reasoning model, just like a fault forest, can be used to determine the essential components. The critical pieces and their locations become the crucial assets to safeguard. Figure two is the top-level portion of a generic wrong doing tree intended for facilities.

3. Consequence Dedication

The next step is to categorize unwanted events or loss of important assets. The proposed types of consequences are similar to those used by the Department of Protection per Military Standard 882C. Yes
