Don’t Use USB Drives in GMP Data Terminals Without Control and Validation

Remember: Never plug unvalidated USB drives into GMP systems — they can compromise data integrity, introduce malware, and breach regulatory controls.

Why This Matters in GMP

GMP data systems — including laboratory instruments, SCADA systems, HMI panels, and LIMS servers — contain sensitive manufacturing and testing data that must be secure, accurate, and traceable. The use of uncontrolled USB devices bypasses built-in audit trails, introduces cybersecurity vulnerabilities, and creates opportunities for unauthorized data manipulation or loss.

For example, a quality analyst may unknowingly use a USB drive carrying malware to export HPLC data. This could corrupt the system, alter batch data, or result in irreversible data loss. Additionally, such practices lack traceability, leaving gaps in the audit trail and violating ALCOA+ principles of data governance.

Regulatory and Compliance Implications

21 CFR Part 11 emphasizes the need for audit trails, secure access, and electronic record integrity in computerized systems. EU GMP Annex 11 reinforces the need for system validation, controlled access, and data protection. WHO GMP advises strong IT controls to prevent data corruption, unauthorized access, and loss.

Auditors often request logs of data transfers,
