when completing a threat/hazard analysis, you should do all of the following actions, except for: a. 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. b. ask community organizations, critical infrastructure owners and operators, and other non traditional partners to assist with the process. c. use online data sources and local subject-matter experts to understand potential threats and hazards. d. use existing thiras, hazard analysis, threat assessments, and homeland security strategies to identify initial threats and hazards.
