Navigating 21 CFR Part 11: Open vs. Closed Systems

Compliance with 21 CFR Part 11 is essential for ensuring the integrity and security of electronic records and signatures. One crucial aspect of this regulation is understanding the difference between open and closed systems and their respective compliance requirements. This blog delves into these distinctions, explores the specific compliance challenges associated with each, and illustrates how Arbour Group can help life sciences companies navigate these complexities effectively.

What is 21 CFR Part 11?  

21 CFR Part 11 is a regulation established by the U.S. Food and Drug Administration (FDA) that sets the criteria for electronic records and electronic signatures to be considered trustworthy, reliable, and equivalent to paper records. This regulation is vital for life sciences companies, ensuring electronic data meets the same rigorous standards as traditional paper documentation.

Understanding Open and Closed Systems  

Open Systems

According to 21 CFR 11.3(b)(9), an open system is an environment where system access is not controlled by the persons responsible for the content of electronic records. This means that users can create accounts and access the system without needing approval from an administrator, making it more accessible and more vulnerable to security risks.

Challenges

Security Risks: Open systems can pose significant security risks due to the lack of controlled access. Unauthorized individuals could potentially access sensitive data, leading to breaches and data integrity issues.

Data Integrity: Ensuring the accuracy and reliability of electronic records can be challenging in open systems. Companies must implement robust controls to protect data from unauthorized access and manipulation.

Compliance Requirements

Encryption: Documents must be encrypted to protect sensitive data from unauthorized access. Encryption ensures that only authorized personnel can read the data, maintaining its confidentiality.

Digital Signatures: Using digital signature standards, such as public key infrastructure (PKI) and multi-factor authentication (MFA), helps verify the signer's identity and maintain the integrity of electronic records.

Examples of Open Systems

Email Systems: Email platforms are examples of open systems where users can create accounts freely. Companies must ensure strong password policies and encryption to maintain the security of email communications.

Cloud Storage Services: Services like Google Drive and Dropbox allow users to store and share files. Companies must implement access controls and encryption to protect sensitive data stored in these open systems.

Closed Systems

As defined by 21 CFR 11.3(b)(4), a closed system is an environment where system access is controlled by the persons responsible for the content of electronic records. Only authorized personnel can access the system, and their actions are monitored and recorded, providing a higher level of security and control.

Challenges

Access Control: It is crucial to maintain strict access control to ensure that only authorized individuals can use the system. This includes implementing user authentication and authorization processes.

Audit Trails: Closed systems must have audit trails that record all user activities and changes to electronic records, ensuring accountability and traceability.

Compliance Requirements

Validation: Systems must be validated to ensure they operate correctly and meet regulatory requirements. This includes testing for accuracy, reliability, and performance.

Audit Trails: Secure, computer-generated, and time-stamped audit trails must be used to record operator entries and actions on electronic records.

User Authentication: Only authorized personnel should be allowed to use the system and electronic signatures, ensuring data integrity and security.

Examples of Closed Systems

Document Management Systems (DMS): These systems manage electronic documents like standard operating procedures and batch records, with access restricted to authorized users.

Audit Trails: QMS software solutions manage quality-related activities within a controlled environment, such as audits and employee training.

Differences Between Open and Closed Systems  

The primary difference between open and closed systems lies in access control. Open systems allow users to create their own accounts, which can introduce security risks and compliance challenges. On the other hand, closed systems require administrative approval for access, providing a higher level of control over data integrity and security. While both systems must comply with 21 CFR Part 11 requirements, open systems have additional requirements, such as encryption and digital signature standards.
