R.A. Method phases supported

  • Context establishment : MEHARI allows covering either an entire organization or to select and zoom on particular parts (affiliate, business activity, type of asset or threat, …) using specific scope and boundaries
  • Stakes analysis and assets classification : based on business consideration of consequences of dysfunctions and allowing to give a “value” to information attached assets (primary and secondary, according to ISO/IEC 27005) The types of assets considered are: services, information data and effective compliance to regulations.
  • Risk identification : MEHARI gives indications for the business stakes identification and valuation, the resulting classification of assets (according to ISO 27005) for the Availability, Integrity and Confidentiality security criteria is performed. Also the likelihood of the various threats is identified and the evaluation of the security measures to reduce the risk may be collected from audit questionnaires. All the elements for risk evaluation are available for the next phases
  • Risk analysis : MEHARI knowledge bases provide comprehensive lists of risk scenarios associated with the assets and the various threats. The combination of stakes, threats and vulnerabilities included in the method allows analyzing the risks situations and preparing for the risk assessment.
  • Risk assessment : This is based on the quantification of these elements, and the seriousness for the organization is established on a scale with 4 levels. The most serious scenarios (level 4 and 3) will have to be managed

R.M. Method phases supported

  • Risk assessment: the critical risks may be displayed and analyzed under various other forms: by asset criterion, type of threat, actor, etc
  • Risk treatment : The Risk managers or auditors have the capacity to select the treatment option (reduce, accept, transfer/share, avoid) and, in the case of a decision of reduction, MEHARI provides the capability to select the additional security measures for the reduction of likelihood and/or impact and to integrate them in additional projects depending on the level of the resources and types of organization
  • Risk acceptance : the capacity to indicate individually the acceptance of scenarios is provided. Further indications in the case of risk sharing (e.g. with insurance) is collectable
  • Risk communication : All the stakeholders are associated since the beginning (stakes analysis) and the operational staff (either IT, communications, etc.) contributes to the analysis. Inputs to the building or revision of the Information security policies are provided as well as directions for security projects. Once filled during the risk management cycle, the knowledge base file constitutes a folder for further work and communication.
