TL;DR: The article says 1 thing stands out first: planning determines whether analysts collect the right artefacts before time pressure narrows the case, based on Cyber Triage's case work. Investigation plans still need human validation of evidence sources, scope, and environment details before collection starts.
Editorial analysis by NHI Mgmt Group, based on content published by Cyber Triage: “AI in DFIR 101: Why You Should Use AI for Planning”.
Key questions
Q: When should analysts rely on a deterministic playbook instead of AI?
A: Use deterministic playbooks when the incident class is known, the environment is well documented, and the evidence mapping is repeatable.
Q: How do teams keep AI-generated investigation plans defensible?
A: Keep AI in the candidate-generation stage and require a human to verify the chosen evidence sources, system scope, and investigative assumptions.
Q: How should security teams use GenAI in incident investigation planning?
A: Use GenAI as a planning assistant when the team needs to draft a new evidence map, find a near-match playbook, or adapt a template to a specific environment.
Practitioner guidance
- Standardise evidence-mapping playbooks for common incident questions Define a minimum evidence set for questions such as persistence, credential theft, and exfiltration, then store the mappings where analysts actually search during an incident.
- Use GenAI only for playbook drafting and gap-finding Allow AI to suggest candidate data sources and related investigative paths, then require a human to confirm relevance before the plan is used.
- Version control environment-specific substitutions Keep hostnames, IP ranges, logging platforms, and identity systems as separately maintained fields so customisation does not depend on memory during an incident.
Bottom line: Investigation planning determines whether analysts collect the right artefacts before time pressure narrows the case.

Planning is a control function, not a clerical step. When investigators fail to plan evidence collection, the result is not just slower triage, it is incomplete attribution and avoidable blind spots. That matters in IAM and NHI-adjacent investigations because authentication logs, process history, and credential artefacts are often the difference between a hypothesis and a defensible finding. The field should treat planning as a governed part of response design, not a convenience layer.
A question worth separating out:
Q: Why do investigation playbooks need regular customisation?
A: Because the same incident class can land in different logging stacks, identity systems, and endpoint configurations. If the playbook is not adjusted for the current environment, analysts waste time collecting the wrong evidence or miss the artefacts needed to support attribution and containment.
