• Review and analyze risk-based Security information and event management (SIEM) alerts when developing hunt hypotheses.
• Review open-source intelligence about threat actors when developing hunt hypotheses.
• Plan, conduct, and document iterative, hypothesis based, tactics, techniques, and procedures (TTP) hunts utilizing the agile scrum project management methodology.

The hypothesis contains all data required, is free from errors in grammar, spelling, content, and submitted in the specified times that are stated in the deliverable section.
• Hunt Reports: Hunt reports describe the original hypothesis and all iterations. At each stage, the report details how the hypothesis was tested and the results. The reports contain all data required, is free from errors in grammar, spelling, content, and submitted in the specified times that are stated in the deliverable section.
