Do Assign Digital Access Logs to Every GMP Terminal to Ensure Traceability
Remember: Each GMP data terminal must maintain its own unique access log — this enables traceable, secure, and compliant data entry and review.
Why This Matters in GMP
Digital access logs provide a transparent, tamper-evident record of who accessed a system, what changes were made, and when. Without terminal-specific logging, actions become untraceable, allowing unauthorized changes, data overwrites, or deletions to go unnoticed. In GMP settings where electronic records guide product release and testing decisions, this compromises data integrity and system trustworthiness.
For instance, if multiple analysts share login credentials or a system lacks user-specific audit trails, it becomes impossible to attribute critical actions — such as result approval or method ing — to an individual. This lack of traceability not only violates compliance expectations but also impedes root cause investigations during deviations.
Regulatory and Compliance Implications
21 CFR Part 11 requires that all electronic records have secure, user-specific access and a full audit trail. EU GMP Annex 11 mandates system security, access control, and electronic traceability. WHO GMP emphasizes that each computerized GMP system should record access logs for all critical transactions
Regulators expect documented evidence of login logs, user roles, and audit trail reviews. If terminal access is shared, untracked, or lacks logs, it often leads to serious data integrity citations, especially for systems managing analytical, production, or validation data.
Implementation Best Practices
Configure each terminal with individual user accounts and secure password policies. Enable auto-logging of login time, activity, and logout. Store access logs in a centralized, secure location with restricted QA oversight. Use biometric or badge-based login if available for added traceability.
Regularly review access logs for anomalies. Conduct periodic system audits to verify that terminals are not being used without logging and that all log entries are maintained per your data retention policy. Ensure all personnel understand the implications of terminal misuse or shared logins.
