SECURITY RISK MANAGEMENT (SRM
)
1.1. When referring to SRM
1.1.a. Program risk
1.1.b. Speculative risk
1.1.c. Pure risk
2.
SRM TEAM
STEP 1
3.
ASSET IDENTIFICATION
3.1. Identification of the assets to be safeguarded
3.2. Each asset must be identified and quantified
3.3. Until all assets have been identified and quantified the program
3.4. The SRM team determines the specific assets
STEP 2
4.
DETERMINATION OF THE ASSET CRITICALITY
4.1. Human life
4.2. Specific cost factors
4.3. The "Impact of Loss" formula
4.4. The individual weighting factors
STEP 3
5.
ASSIGNING A CRITICALITY RATING
STEP 4
5.
IDENTIFICATION OF THE THREATS ASSOCIATED WITH EACH ASSET
5.1. All threats to an asset must be identified
5.2. Every threat associated with an asset
5.3. When a loss event does occur
5.4. The threat identification process incorporates
STEP 5
6.
IDENTIFICATION AND ASSESSMENT OF EXISTING COUNTERMEASURES WITH REFERENCE TO THE IDENTIFIED THREATS
.
6.1. Countermeasures are those actions taken to eliminate
6.2. Existing countermeasures must be identified
STEP 6
7.
ASSIGNMENT OF AN ASSET VULNERABILITY RATING
7.1. Each asset which has been prioritized according to criticality
7.2. Vulnerabilities are those physical, technical, administrative, procedural, or human characteristics
7.3. With regard to any asset the level of risk is directly related to
7.4. An alphabetical rating from "A" through "D" is assigned to each asset
STEP 7
8.
DETERMINE THE LEVEL OF RISK, (RISK LOGIC)
.
8.1. At this point in the SRM process each asset
8.1.a. The first designator, numerical designator
8.1.b. The second designator, letter designator
8.1.c. The combinations of the two designators
8.1.d. The assets are reprioritized
8.2. Using the Risk Level Values assigned, each asset is entered into a risk logic matrix as shown below
8.3.
Unacceptability
and
Acceptability
–
Risk

DECISION MAKING
9.1. The goal of the SRM process is to provide
9.2. The risk logic matrix presentation permits
9.3. For example, the risk levels reflected in the risk logic table
STEP 9
10.
USING THE MATRIX
10.1. The term managing risk is significant
10.2. The process can be applied equally effectively to any asset provided
10.3. When the process has been completed to the stage where the risk logic matrix
10.4. This process ensures that the criticality and impact of loss
10.5. Decision makers will be able to use the most cost effective measures that can be employed
10.6. Risk reduction measures include physical modification
10.7. Decision makers shall ensure that established minimum FAA security
10.8. The overall risk severity for a given threat or loss
STEP 10
11.
DETERMINE APPROPRIATE RISK REDUCTION METHODS AND THEIR ASSOCIATED COSTS.
11.1. Identify all required countermeasures
11.2. Identify cost effective countermeasure alternative approaches
STEP 11
12.
COST BENEFIT ANALYSIS (CBA).
12.1. All of the essential elements in the SRM process
12.2. CBA shall be applied to the results of the SRM process
12.3. Decision makers use the results of CBA as necessary
