  • Document key event details and analytic findings in analysis reports and incident management systems.
  • Identify, extract and characterize network indicators from cyber threat intelligence sources, incident reporting and published technical advisories/bulletins.
  • Assess cyber indicators/observables for technical relevance, accuracy, and potential value/risk/reliability in monitoring systems.
  • Recommend detection and prevention/mitigation signatures and actions as part of a layered defensive strategy leveraging multiple capabilities and data types.
  • Develop IDS signatures, test and tune signature syntax, deploy signatures to operational sensors, and monitor and tune signature and sensor performance.
