An improved candidate would also:
  • Provide advanced recommendations to address gaps in logging and detections based on an analysis of threats and data
  • Create detailed and thorough testing plans to ensure higher chance of accurate detections
  • Produce clear metrics and reports (FP rate, backlog) for technical and executive audiences

An excellent candidate would also:
  • Create advanced use cases for detections based on an analysis of threats and data, including sample criteria to identify the behavior and mapping detections to MITRE Telecommunication&CK
