When completing a threat/hazard analysis, you should do all of the following actions, except for: a. ask community organizations, critical infrastructure owners and operators, and other non traditional partners to assist with the process. b. avoid recent history or official records since they may not always be the best indicator of the presence or severity of a threat or hazard. c. use existing thiras, hazard analysis, threat assessments, and homeland security strategies to identify initial threats and hazards. d. use online data sources and local subject-matter experts to understand potential threats and hazards.
