The establishment of the Information Security Management System is a very laborious process. Nevertheless, setting standards on how to ensure information security and how to better protect information is a crucial outcome for that organization.
Information Security Management System the way that each organization will follow is almost the same.
Scope of information security study
The first thing to do is to determine the scope and limits of the study. A system can be set up for an entire organization or for a particular department. In any case, the limits of the study should be complete and correctly defined. The scope should be determined in line with the decision of the top management and the organization's information security objectives.
Information security policy
This policy is determined by the senior management and sets the objectives of the study and determines the risks to be evaluated and the criteria for risk management. Top management should always stand behind the information security policy.
Risk assessment method
A risk assessment method should be identified in accordance with the information security policy. Accordingly, acceptable risk levels should be identified and criteria should be set. Information that should be protected by creating a risk map should be determined according to the degree of impact and the likelihood of risk occurring.
Identification of risks
The risks that threaten the existence of information should be identified by using the risk assessment method to be determined. In this study, an inventory of information assets will be prepared. Information assets to be included in the Information Security Management System will be listed according to their type and severity. The emergence of top-secret information can do great harm to the organization, but making the same information unusable may be less damaging.
Assessment of risks
The measures to be taken for the risks to be determined are decided in this step. Risk can be eliminated or reduced to acceptable levels by appropriate controls. Or, risk factors are eliminated and risk is avoided.
Approval of senior management
After the risk management study is completed, it is necessary to get approval from the senior management to apply it.
If a risk cannot be completely eliminated, it may be an acceptable risk at the discretion of the top management.
