This is a ready-to-use incident response plan for computerized systems that hold GxP records. It is not a generic IT plan: a security incident on a GxP system is also a potential data-integrity event, so this plan adds a mandatory data-integrity impact assessment and a link into the quality system. Replace every <<FILL: ...>> placeholder, set your document numbers, and route it through document control. Rehearse it before you need it. A worked filled specimen for a ransomware scenario follows. This is general guidance to adapt and verify, not legal advice.

1. Purpose and scope
This plan defines how <<FILL: COMPANY NAME>> detects, contains, assesses, recovers from, and reports a security incident affecting a validated GxP computerized system, so that data integrity is protected and demonstrated, the validated state is restored before GxP use resumes, and reporting obligations are met. It applies to all systems that create, modify, or store GxP records. It works with the deviation, CAPA, backup and recovery, and change-control procedures rather than replacing them.
2. Roles
| Role | Responsibility |
|---|---|
| Incident lead (IT Security) | Coordinates the response; convenes the team; owns the incident record. |
| QA / data-integrity lead | Owns the data-integrity impact assessment; decides GxP impact and disposition; links to deviation and CAPA. |
| System / process owner | Provides system and process context; supports impact scoping. |
| IT / system administrator | Executes containment and recovery under direction. |
| Communications / legal / privacy | Assess external notification obligations (breach law, regulatory). |
| Senior management | Escalation and decisions on significant impact. |
3. Severity classification
Classify at triage; classification drives who is engaged and how fast. Any incident touching a GxP system engages QA from the start.
| Severity | Definition | Response |
|---|---|---|
| Critical | Active compromise of a GxP system; records may be altered or destroyed; production or release affected | Immediate full-team response; senior management engaged |
| High | Confirmed incident on a GxP system with limited or contained impact | Prompt response; QA engaged; management informed |
| Medium | Suspected or minor incident with no confirmed GxP data impact | Standard response; investigate and confirm |
| Low | Security event with no GxP relevance | Handle under general IT process; log |
4. Response phases
4.1 Detect and report
Incidents surface from monitoring and alerts, vendor security bulletins, failed integrity checks, or a user report. There is one clear reporting channel (<<FILL: channel>>) that every user knows. Record the time and source of detection.
4.2 Triage and classify
Assess severity per section 3 and, specifically, whether a GxP system or GxP records are affected. Engage QA whenever a GxP system is in scope. Open the incident record.
4.3 Contain without destroying evidence
Isolate the affected system (network segmentation, disable compromised accounts) to stop spread, but preserve logs, audit trails, and forensic evidence rather than wiping and rebuilding immediately. You may need that evidence to understand the attack and to prove what did or did not happen to the data.
4.4 Assess data-integrity impact (the GxP-specific step)
QA leads a documented assessment answering:
- Were GxP records created, altered, or deleted during the incident window?
- Is the audit trail intact and does it cover the incident window?
- Are results and decisions made from the affected data still reliable?
- Which batches, studies, dispositions, or releases are potentially affected?
This assessment usually opens a deviation with backward reach to the last known-good state. It gates whether affected data may be used.
4.5 Recover to a validated state
Restore from a tested, trusted backup taken before the compromise, and verify the system is back in its validated configuration before returning it to GxP use. Confirm the restored data is complete and uncorrupted, including the audit trail. A restore that returns service but cannot prove data integrity is not complete.
4.6 Root cause and CAPA
Investigate why it happened and what allowed it, and drive corrective and preventive action through the quality system, including whether an access, patching, or monitoring control must change.
4.7 Report
Notify internally per this plan. Assess and act on external obligations: data-privacy breach notification laws where personal or patient data was exposed, and GxP reporting expectations where the reliability of regulated data or a trial’s integrity is affected. Know the applicable clocks in advance.
5. Acceptance criteria
The response is acceptable when: the incident was reported through the defined channel and classified; containment preserved evidence; a documented QA-led data-integrity impact assessment was completed and gated data use; recovery restored a verified validated state from a clean backup; root cause and CAPA are tracked to closure; and external reporting obligations were assessed and met within their windows.
6. References
EU GMP Annex 11 (security and control of computerized systems); 21 CFR Part 11. FDA Data Integrity and Compliance With Drug CGMP (2018); MHRA GXP Data Integrity Guidance; PIC/S PI 041. Applicable data-privacy breach-notification law for the jurisdictions you operate in. Your deviation, CAPA, backup/recovery, and change-control SOPs.

Filled specimen
The following walks a ransomware incident on an illustrative laboratory system through the plan. The details are illustrative; replace them with your own.
| Phase | What happened |
|---|---|
| Detect and report | Endpoint alert plus an analyst reporting files renamed with an unfamiliar extension on the CDS file share, 08:12. Reported to the security channel; incident IR-2026-004 opened. |
| Triage and classify | GxP system (chromatography data) affected, records possibly encrypted. Classified Critical; full team convened; QA engaged; management informed. |
| Contain | CDS server isolated from the network; affected service accounts disabled; logs and the encrypted volume preserved for forensics rather than reimaged. |
| Data-integrity assessment | QA determined which analytical runs fell in the incident window (04-Aug 18:00 to 05-Aug 08:12), confirmed the audit trail on the database (separate from the encrypted share) was intact, and quarantined 3 result sets pending confirmation. Deviation DEV-2026-0221 opened. |
| Recover | Restored the file share and application from the 04-Aug 22:00 backup (pre-compromise); verified the validated configuration and that restored data plus audit trail were complete before returning the system to use. |
| Root cause and CAPA | Root cause: a service account with an unrotated credential and excessive share permissions. CAPA: rotate and vault service credentials, tighten share permissions to least privilege, add monitoring for mass file renames. |
| Report | No personal or patient data on the system, so no privacy-breach notification; documented the GxP data-integrity assessment for the file and the eventual product-impact conclusion in the deviation. |
The specimen shows the GxP difference in action: the team did not just restore service, it proved which results were in scope, confirmed the audit trail survived, quarantined the doubtful data, and closed the reliability question through a deviation before any affected result was used.
Common inspection findings this plan prevents
- A security incident on a GxP system handled purely as an IT event, with no QA involvement and no data-integrity assessment.
- Containment that wiped and rebuilt the system, destroying the evidence needed to prove what happened to the data.
- Recovery that restored service but never confirmed the restored data and audit trail were complete and uncorrupted.
- No assessment of which batches or studies were affected, leaving data reliability unresolved.
- Reporting obligations discovered during the incident instead of known in advance, so a clock was missed.
How to adapt this plan
- Set your document number, owner, and systems in scope.
- Align the severity bands and roles to your organization, and name the reporting channel.
- Point the recovery step at your tested backup and DR procedure, and the impact step at your deviation and CAPA SOPs.
- Confirm the data-privacy and GxP reporting obligations and their clocks for your jurisdictions.
- Rehearse the plan with a tabletop on the stated cadence, and update it from what the rehearsal reveals.
