USE CASES

Where this instrument fits.

  • Plan evidence collection after an incident
  • Identify telemetry gaps before or during DFIR
  • Structure a timeline-building workstream
  • Create preservation priorities and owner assignments
INPUTS

Required input fields.

  • Incident type (required): Ransomware, Business email compromise, Cloud account compromise, Insider incident, ...
  • Environment (required): Cloud-first, Hybrid, On-premises
  • Log source coverage (required): Central and retained, Partial, Weak or short retention
  • Known time window (required): Known narrow window, Broad window, Unknown
  • Business impact (required): Low, Material, Critical

Data handling: this interface uses the L2ET protected same-origin instrument engine. Do not enter confidential, regulated, privileged, incident, medical or sensitive operational data.

METHOD

Incident Timeline logic.

Maps incident type to evidence families, prioritizes volatile and high-value sources, and converts log coverage and time-window uncertainty into preservation priority.
