Data protection and encryption are critical components of any organisation’s security strategy, focusing on protecting sensitive data from unauthorised access, loss, or corruption. This sector includes practices such as encryption, secure data storage, data masking, and the implementation of robust access control mechanisms for both structured and unstructured data. By securing data, organisations can mitigate the risks associated with data breaches, protect customer privacy, and ensure compliance with data protection regulations, such as the GDPR or the Data Protection Act.

Level 1 Certification

———————————————————————————————————

Measure 4.1: Implement Basic Data Encryption for Sensitive Data

Does your enterprise ensure that sensitive data is encrypted, both when stored (data at rest) and when transmitted (data in transit)?
Example: Enable encryption on all devices storing sensitive data (e.g., laptops, mobile devices, and external storage). Use simple encryption tools like BitLocker for Windows or FileVault.

Measure 4.2: Implement Access Control Policies for Sensitive Data

Does your enterprise restrict access to sensitive data based on user roles, ensuring that only authorised personnel can view or modify it?
Example: Limit access to sensitive files, databases, and information to those employees who require it for their role, ensuring data is not unnecessarily exposed.

Measure 4.3: Store Sensitive Data Securely

Does your enterprise store sensitive data in secure environments, such as encrypted databases or cloud services with robust security features?
Example: Use cloud storage providers such as Google Drive or Microsoft OneDrive with built-in encryption and security features to store sensitive data securely.

Measure 4.4: Educate Employees on Data Protection Best Practices

Does your enterprise educate employees on the importance of protecting sensitive data and the use of encryption?
Example: Provide basic training on data protection best practices, such as handling sensitive data securely and recognising risks related to data breaches.

Level 2 Certificaton

To achieve Level 2: Level 1 must also be achieved.

———————————————————————————————————

Measure 4.5: Implement Stronger Encryption Solutions for Data at Rest and In Transit

Does your enterprise use advanced encryption solutions for all sensitive data, including emails, documents, and databases, both at rest and in transit?
Example: Implement SSL/TLS encryption for email communications and use encryption standards for files and databases.

Measure 4.6: Deploy Data Loss Prevention (DLP) Tools

Does your enterprise implement DLP tools to prevent unauthorised access, sharing, or transmission of sensitive data outside the organisation?
Example: Use DLP solutions such as Symantec DLP or Digital Guardian to monitor and restrict the movement of sensitive data and prevent unapproved transfers via email or file sharing.

Measure 4.7: Conduct Regular Access Reviews and Audits

Does your enterprise regularly audit user access to sensitive data to ensure compliance with access control policies and verify that access is appropriate for employees’ roles?
Example: Conduct quarterly or bi-annual reviews of user access permissions for systems that handle sensitive data, ensuring employees no longer have access to data they don’t need for their current role.

Measure 4.8: Implement Secure Data Storage Solutions

Does your enterprise use encrypted storage solutions for data backup and long-term archiving?
Example: Use encrypted cloud storage providers or dedicated encrypted servers for data backups and long-term data retention.

———————————————————————————————————

Level 3 Certificaton

To achieve Level 3: Level 2 and Level 1 must also be achieved.

———————————————————————————————————

Measure 4.9: Implement End-to-End Encryption for Critical Communications

Does your enterprise implement end-to-end encryption for all critical communications, such as internal messaging and email correspondence, to protect sensitive information?
Example: Use platforms like Signal or ProtonMail, which provide end-to-end encryption, for sensitive communications that require high levels of confidentiality.

Measure 4.10: Utilise Advanced Authentication for Sensitive Data Access

Does your enterprise require multi-factor authentication (MFA) for accessing sensitive data and systems, ensuring that only authorised users can access critical information?
Example: Implement MFA solutions such as Google or Microsoft Authenticator to ensure that access to sensitive data is secured with an additional layer of authentication beyond just passwords.

Measure 4.11: Enforce Data Masking Techniques for Sensitive Data Exposure

Does your enterprise implement data masking techniques for non-production environments where sensitive data might be exposed (e.g., during software development or testing)?
Example: Use data masking software to anonymise sensitive customer data, replacing it with fictional but realistic data in testing environments.

Measure 4.12: Develop and Maintain a Comprehensive Data Protection Strategy

Does your enterprise have a formal, documented data protection and encryption strategy in place, and is it regularly reviewed and updated to ensure ongoing compliance with data protection laws?
Example: Develop a comprehensive data protection policy that covers encryption, access control, data storage, and employee responsibilities, and review this policy annually to keep it up-to-date with evolving regulations like GDPR.
