• Maintain access logs and periodic reviews

Access control is a key requirement for 21 CFR Part 11 Compliance, ensuring that only authorized personnel can view, update, or sign electronic records. Unique login credentials help preserve accountability. Role-based access prevents unauthorized actions and ensures users can only perform tasks relevant to their responsibilities. Systems should include automated timeout features to reduce risks from unattended terminals. Regular review of access logs helps detect any unusual activity or unauthorized access attempts. These controls collectively support secure and compliant digital operations within the pharma industry.

4. Electronic Signatures

Checklist

• Apply two-factor authentication for signing
• Ensure every signature is unique and traceable
• Capture user identity, timestamp, and purpose
• Enforce strict electronic signature SOPs
• Link signatures permanently to the associated record

Electronic signatures must meet strict requirements to support 21 CFR Part 11 Compliance. These signatures must be legally valid, fully traceable, and permanently attached to the corresponding electronic record. Two-factor authentication ensures that signing events cannot be performed by unauthorized individuals. Every signing action must clearly display the meaning and intent behind the signature, such as approval, review, or verification. Documented procedures should define how signatures are assigned, secured, and revoked. A compliant signature framework ensures regulatory trust and strengthens overall 21 CFR Part 11 Compliance.

5. Audit Trails

Checklist

• Capture every creation, modification, and deletion
• Record user identity and timestamps
• Prevent audit trail editing
• Review audit trails regularly
• Maintain secure, long-term storage

Audit trails provide the transparency required for 21 CFR Part 11 Compliance. These records show who performed each action, what was changed, when it occurred, and why it was performed. The system must generate audit trails automatically, and users must never have the ability to modify or delete them. Periodic review of audit trails helps pharma teams identify discrepancies, potential data integrity issues, or fraudulent behavior. A strong audit trail system ensures traceability and supports successful regulatory inspections.

6. Security and Data Protection

Checklist

• Encrypt data during storage and transmission
• Ensure secure backups and disaster recovery
• Use firewalls and intrusion detection systems
• Implement physical access controls
• Maintain comprehensive security SOPs
