USE CASES

Where this instrument fits.

  • Scope incident response priorities
  • Prepare executive incident summaries
  • Identify containment urgency
  • Prioritize identity, network and data review
INPUTS

Required input fields.

  • Compromised identity scope (required): Single low-privilege user, Business app role, Privileged or cloud admin
  • Lateral movement potential (required): Low, Medium, High
  • Data reach (required): Low, Material, Critical
  • Dependency concentration (required): Low, Medium, High
  • Segmentation strength (required): Strong, Partial, Weak

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

Heatmap logic.

Combines identity privilege, lateral movement potential, data reach, dependency concentration and segmentation into a blast-radius pressure map.

Assumptions

  • No live discovery is performed.
  • Estimates depend on accurate architecture knowledge.
  • Containment decisions require incident commander review.
INTERACTIVE INSTRUMENT
