Threat hunting and investigation

Threat hunting and investigation Requirements and security baseline

Baseline alignment. Detection and traffic inspection safeguards selected for the agreed CIS IG. CIS IGs

• Hypothesis-based investigation: scope, supported systems and accountable owners
• Telemetry search and correlation: approved settings, access and dependencies
• Findings and response handoff: acceptance criteria, retention and exceptions

Threat hunting and investigation Deployment and control mapping

• Scope and ownership: Candidate investigation capability for reviewing relevant telemetry and testing threat hypotheses; product selection, coverage and retention remain unconfirmed.
• Approved rollout and acceptance: Controlled pilot covering hypothesis-based investigation and telemetry search and correlation; acceptance test: run a defined hunt against available telemetry, retain a reproducible query and trace a supported finding to its response or disposition.
• Applicable requirements mapped to configuration, validation evidence and approved exceptions

Threat hunting and investigation Client and user guide

• Using hypothesis-based investigation within the approved service scope
• Recognizing failures and reporting a support request
• User responsibilities, access limits and service acceptance

Threat hunting and investigation Technician training outline

• Hypothesis-based investigation: records, configuration and diagnostic checks
• Telemetry search and correlation: authorized administration and exception handling
• Findings and response handoff: validation, evidence and service handoff

Threat hunting and investigation RDA technician workflow

• Identify and assess the requirement; plan the scope, accountable owner and required approvals
• Implement and verify: Run a defined hunt against available telemetry, retain a reproducible query and trace a supported finding to its response or disposition.
• Document the configuration and result; hand off operation, review exceptions and plan lifecycle changes

Threat hunting and investigation Portal and access training

• Named operators, role boundaries and multifactor access where supported
• Service identities, protected credentials and emergency access
• Access approval, periodic review and removal

Threat hunting and investigation Training module template

• Learning objectives and prerequisites: hypothesis-based investigation: records, configuration and diagnostic checks
• Authorized practical exercise: Run a defined hunt against available telemetry, retain a reproducible query and trace a supported finding to its response or disposition.
• Knowledge check, observed result and instructor or responsible-owner sign-off

Threat hunting and investigation Basic installation and acceptance

• Approved platform, owner, permissions and prerequisite checks
• Controlled pilot covering hypothesis-based investigation and telemetry search and correlation
• Acceptance test: Run a defined hunt against available telemetry, retain a reproducible query and trace a supported finding to its response or disposition.

Threat hunting and investigation Advanced deployment and changes

• Extend hypothesis-based investigation to additional approved scope
• Change telemetry search and correlation with impact review and rollback
• Validate findings and response handoff after an approved change

Threat hunting and investigation Technical configuration and integrations

• Hypothesis-based investigation: configuration and dependency records
• Telemetry search and correlation: supported interfaces and permission boundaries
• Findings and response handoff: diagnostic collection, retention and evidence export

Threat hunting and investigation Operational audit and checklist

• Coverage and operating checks: hypothesis-based investigation: coverage, health and unresolved exceptions
• Evidence sample: hunt hypothesis, data sources, time range and coverage limits; finding disposition, response actions and validation
• Review date and owner; pass or fail, exceptions, corrective action and retest evidence

Threat hunting and investigation Tabletop exercises

• A required dependency or responsible provider becomes unavailable
• An access or configuration change interrupts the service
• Reported success conflicts with the observed business result

Threat hunting and investigation Response playbook

• Assess the affected scope, evidence and business impact
• Authorize corrective action, escalation or rollback
• Verify service recovery, retain evidence and update the baseline

Threat hunting and investigation Operational runbooks

• Validate hypothesis-based investigation against the approved design
• Investigate a failure affecting telemetry search and correlation
• Collect findings and response handoff evidence and confirm service acceptance

Threat hunting and investigation Evaluation and lifecycle review

Selection and fit. Compare viable options against the business need, security requirements, existing systems and full operating cost. Record the reasons for the selection, the tradeoffs accepted and the conditions that would prompt a different choice.

Keeping the choice current. Follow supplier notices between scheduled reviews and reassess before renewal or a material change. Check ownership changes, renamed or retired products, subscription and licensing terms, pricing, capabilities and support commitments. Record the effect on security, data handling, integrations and service continuity. Assign an owner to approve adjustments or plan a transition, including data export and removal of access.

• Measured service outcome and practical acceptance results
• Supported scope, access, evidence availability and dependencies
• Licensing or provider terms, maintenance effort and lifecycle cost
