Preparation Of A Risk Analysis, Its Calculation, Importance And Objectives

Preparation of a risk analysis, its calculation, importance and objectives

Goal

Identify the possible threats, and the damages and consequences that they may produce. Carrying out a certain evaluation to mitigate the possible risks.

Importance

• Identify and evaluate environmental and health problems produced by the realization of dangerous activities and the management of toxic substances.
• Verify new and traditional technologies that are used in determining the effectiveness of the different mitigation controls and techniques designed to reduce risks.
• Location of potentially dangerous facilities.
• Make up in an adequate period to mitigate and correct possible risks.

Steps required for its development

1. Define the scope. This is the first step that must be followed for an analysis, establish an analysis of said study. This defines the strategic areas on which security must be improved. A scope can also be defined according to departments, processes or systems.
2. Identify assets. When we have the scope, we must know how to identify what are the assets that are related to the scope, that is, department, systems or processes. To identify them, an inventory can be made on a spreadsheet or table.
3. Identify / select threats. After identifying the assets, we need to identify which are the threats that our assets could affect. This step is to identify what are the characteristics of our teams and what are its vulnerable points.

   You have to take all this into account to estimate the probability and impact for the next phase.

4. Evaluate the risk. At this point we have to take into account the asset inventory, a set of threats to which it is exposed, set of vulnerabilities associated with each asset and the set of implanted security measures. Already with all this, we can calculate what is the risk of each threat towards assets. The calculation of risk is the multiplication of probability due to the impact of this.
5. Treat the risk. When we calculate the risk there are four main strategies to treat it:

• Transfer the risk to a third party, that is, to hire for insurance that covers the damages caused by some information leakage.
• Eliminate risk, this is when the process in which the risk is involved can be eliminated.
• Take the risk.
• Implement measures to mitigate it, this is done by hiring backup Internet to access services from the cloud if the main internet line falls.

conclusion

In this document we could see how a risk analysis, its importance and objectives is composed. We could also see where they can be used and thus have a study of possible threats and unwanted or unpredictable events and which consequences they can produce.

These characteristics help provide possible damage to the system infrastructure and have a prognosis in terms of maintenance. It is also one of the most used tools for disaster evaluation.
