Bow Tie Risk Assessment

A good Bow Tie Risk Assessment may require analysis of:
1. Hazards and threats (e.g., software viruses)
2. Barriers to prevent catastrophic event (e.g., antivirus software, periodic scans)
3. Events (e.g., system shutdown due to software virus)
4. Barriers to prevent harm to others (e.g., shutdown and full system scan)
5. Consequences of not preventing virus intrusion
