IR-5 Incident Response

Incident Monitoring

High Risk Moderate Low Cost

IR-5 requires tracking and documenting information system security incidents. Monitoring here means maintaining situational awareness of open incidents — status, owners, evidence, and timelines — not only initial detection. Healthcare organizations need a durable incident register that supports IR handling, leadership reporting, and HIPAA documentation duties.

Control Objective

Maintain an authoritative, up-to-date record of security incidents so nothing falls through cracks and every case has ownership, status, and evidence trail.

Implementation Guidance

  1. Use a single incident register (ticketing/IR platform) for security and privacy-impacting events.
  2. Capture required fields: discovery time, reporter, systems/ePHI involved, severity, commander, containment status, and closure rationale.
  3. Update status throughout the lifecycle — not only at open and close.
  4. Link related alerts, forensic notes, and AU-6 findings to the parent incident.
  5. Dashboard open incidents for on-call and compliance leadership.
  6. Retain incident records per policy and HIPAA documentation retention.
  7. Include BA-reported incidents in the same register with source tags.
  8. Reconcile monthly: open tickets vs SIEM major alerts to catch untracked events.

Real-World Use Cases

How this control shows up in healthcare and HIPAA-covered environments.

Multiple phishing reports same morning

Help desk gets 12 phish clicks. IR-5 monitoring rolls them under one campaign incident with linked user tickets so containment (resets, session kills) is coordinated rather than 12 disconnected chats.

Long-running vendor investigation

A cloud EHR hoster reports an ongoing investigation. IR-5 tracks weekly status, evidence received, and privacy impact updates until closure — visible to compliance.

Forgotten 'low' ticket that grew

A minor malware ticket stayed open without updates. Monitoring metrics flag stale incidents; escalation finds lateral movement and upgrades severity.

Best Practices

  • One register for security incidents organization-wide.
  • Mandatory field completion before severity assignment.
  • SLA for status updates on open high/critical incidents.
  • Link privacy breach assessments to the same ID.
  • Retain records for required periods.
  • Review stale incidents in weekly ops meetings.

Common Gaps & Violations

  • Incidents only in email threads.
  • No shared view between IT and privacy.
  • Closed without documenting outcomes.
  • BA incidents tracked separately and lost.
  • Detection alerts never converted to incident records.

Required Documentation

  • Incident monitoring / tracking procedure
  • Incident record field standard
  • Tool screenshots or exports of the register
  • Retention schedule for incident records
  • Metrics reports (open aging, MTTR)

How to Test & Validate

  1. Open a test incident and verify required fields and ownership.
  2. Confirm privacy can access linked records appropriately.
  3. Review aging report for stale open incidents.
  4. Trace a recent SIEM critical alert to an IR-5 record.
  5. Verify retention settings.

Audit Considerations

Assessors sample incident tickets for completeness and timelines. Sparse or missing documentation of known events is a common HIPAA incident-procedure finding.

HIPAA Mapping

How this NIST control supports HIPAA Security Rule expectations.

  • 164.308(a)(6)(ii) — identify and respond to security incidents; document incidents and their outcomes.
  • 164.316 Documentation — retain required policies and procedures documentation, including incident records as implemented.
  • 164.404 Breach notification — timelines depend on knowing when an incident was discovered (tracking matters).

Compliance Tips

  • Use one incident ID across Slack, tickets, and breach worksheets.
  • Train help desk on when to open an IR-5 record vs a normal service ticket.
  • Export monthly incident summaries for leadership and risk meetings.

Frequently Asked Questions

Is IR-5 the same as SIEM monitoring?

SIEM detects; IR-5 ensures incidents are tracked and documented as cases through closure.

Should privacy incidents use a separate system?

They can, but link IDs — auditors struggle when security and privacy histories cannot be correlated.

How long should we keep incident records?

Follow your documentation retention policy; HIPAA often drives at least six years for related documentation — confirm with counsel.
