When doing threat and risk assessments it never hurts to have tools and resources to help you get through. Here is a tool that was put out by the RCMP and Canadian Security Establishment called “Harmonized Threat and Risk Assessment (TRA) Methodology”.
From Royal Canadian Mounted Police site:
This initial version of the Harmonized TRA Methodology should be regarded as an interim release pending completion of the policy suite renewal project by the Treasury Board Secretariat. Of necessity, it will require updating once the Government Security Policy and supporting standards have been revised and replaced. That being said, the actual mechanics of the methodology are likely to remain the same, only references to the superior policies, directives and standards are expected to change significantly.
There are a number of tools as appendices that could be useful. Give it a whirl.
