Disk & Timeline Analysis
Reconstruct activity from file systems, logs, execution artifacts, and application history.

Operating context
Timeline analysis normalizes heterogeneous timestamps and helps test incident hypotheses. Clock drift, collection gaps, and artifact semantics must remain visible.
- Define the security decision that disk & timeline analysis must support.
- Assign accountable owners, escalation paths, service levels, and privacy boundaries.
- Measure signal quality, response consistency, operational cost, and improvement over time.
Operational workflow
- 01
Establish scope, dependencies, normal behavior, and a documented baseline.
- 02
Collect the minimum telemetry and context needed for disk & timeline analysis.
- 03
Correlate independent signals and state confidence before taking disruptive action.
- 04
Document the decision, evidence, containment or control action, and responsible owner.
- 05
Review the outcome, tune the process, and validate the improvement with a safe test.
Signals, evidence & decisions
| Signal or artifact | Decision it supports |
|---|---|
| forensic image or targeted acquisition | Establish event sequence and affected scope. |
| normalized super-timeline | Confirm identity, asset, or control context. |
| artifact provenance and parser version | Support containment, recovery, or tuning. |
Record source, timestamp, collection method, confidence, owner, and disposition. Preserve the smallest useful evidence set and document any uncertainty.
Implementation & improvement
- Work from verified copies.
- Preserve original timezone and timestamp meaning.
- Annotate inference separately from observed facts.
