Path summary
This path helps you keep facts, judgments, hypotheses, and unknowns separate while an investigation changes. It covers scope states, multi-source timelines, containment choices, evidence preservation, ownership, validation, and handoff.
Audience, difficulty, and effort
Audience: SOC analysts, incident responders, security engineers, identity security analysts, system administrators, investigation coordinators, and security operations leads. Difficulty: beginner to intermediate. Prerequisites: basic security-event terminology, common log sources, and the ability to separate facts from uncertainty. Estimated effort: about 75 minutes.
Why this path matters
An alert is not automatically an incident, and an initial scope is provisional. Evidence may arrive late, clocks may disagree, and containment can affect evidence. A clear record helps teams revisit what is known, what remains unresolved, who owns the next action, and when to reassess.
Learning outcomes
- Define a defensible initial scope without treating a hypothesis as fact.
- Build a multi-source timeline while recording source timestamps, gaps, and uncertainty.
- Coordinate containment and evidence preservation with named owners and validation steps.
- Prepare a structured handoff with residual risk and reopening triggers visible.
Suggested sequence
Lesson 1
Scoping an Incident Investigation
Set provisional boundaries, evidence needs, and reassessment triggers.
Open lesson 1Lesson 2
Building and Validating an Incident Timeline
Normalize timestamps, preserve provenance, and label inference.
Open lesson 2Lesson 3
Coordinating Containment, Evidence, and Handoff
Choose proportionate actions, validate them, and transfer open questions.
Open lesson 3How the lessons connect
Scope establishes the question and evidence boundaries. The timeline tests sequence and confidence. Containment and handoff turn the current record into owned, reviewable work without claiming the investigation is complete.

Completion boundary
Completion means reviewing the lessons and exercises. It does not prove mastery, certification, forensic authority, or authorization to contain, recover, or close an incident. Real investigations require local procedures, evidence, legal and business requirements, approvals, and appropriate authority.
Next learning direction
Continue with Identity and Access Defense when that Learning Path becomes available.
Limitations
These examples are fictional. They cannot establish compromise, complete evidence collection, attribution, containment effectiveness, or recovery readiness in a real environment.
