Risk Frameworks

Оглавление

A risk framework is a structured process for identifying, assessing, and managing an organization's risks. A number of frameworks have been developed to identify and evaluate risk. These frameworks have evolved to address the unique needs of different industries and regulations. Individually, these frameworks address assessment, control, monitoring, and audit of information systems in different ways, but all strive to provide internal controls to bring risk to an acceptable level. While there are several internationally accepted risk frameworks, a number of industry-specific frameworks have also been developed to meet specific needs.

Regardless of the framework, to effectively address risk in an organization, standard processes to evaluate the risks of operation of information systems must take into account the changing threat environment, the potential and actual vulnerabilities of systems, the likelihood that the risk will occur, and the impact to the organization should that risk become realized.

From a governance perspective, the selection of a framework should create a controls environment that is as follows:

 Consistent: A governance program must be consistent in how information security and privacy are approached and applied.

 Measurable: The governance program must provide a way to determine progress and set goals. Most control frameworks contain an assessment standard or procedure to determine compliance and, in some cases, risk as well.

 Standardized: As with measurable, a controls framework should rely on standardization so results from one organization or part of an organization can be compared in a meaningful way to results from another organization.

 Comprehensive: The selected framework should cover the minimum legal and regulatory requirements of an organization and be extensible to accommodate additional organization-specific requirements.

 Modular: A modular framework is more likely to withstand the changes of an organization, as only the controls or requirements needing modification are reviewed and updated.

There are dozens of different risk management frameworks. While many of the frameworks address specific industry or organizational requirements, you should be aware of the broad characteristics of the more common frameworks.
