GDPR Portal

1. GDPR Portal

The General Data Protection Regulation (GDPR) is a regulation in EU law on data protection and privacy in the European Economic Area (EEA) and the United Kingdom. It came into effect on 25 May 2018, and significantly impacts how organizations worldwide handle the personal data of individuals within these regions. This portal serves as a central resource for understanding GDPR compliance within the context of a MediaWiki installation and its associated processes. We'll cover the core principles, the implications for wiki administrators and users, practical implementation steps, and tools for managing GDPR requests.

What is GDPR?

GDPR isn't simply about technical changes; it's a fundamental shift in how data is viewed and treated. Previously, data protection laws often focused on *notification* – informing authorities about data processing. GDPR, however, is built on principles of *accountability* – organizations must demonstrate they are actively protecting personal data. The key principles include:

• Lawfulness, Fairness, and Transparency: Data must be processed lawfully, fairly, and in a transparent manner. This means clearly explaining to individuals *why* their data is being collected and *how* it will be used. See Privacy Policy for more detail.
• Purpose Limitation: Data can only be collected for specified, explicit, and legitimate purposes. It cannot be used for incompatible purposes later.
• Data Minimisation: Only the data necessary for the specified purpose should be collected. Avoid collecting excessive or irrelevant information.
• Accuracy: Data must be accurate and kept up to date. Individuals have the right to rectify inaccurate data.
• Storage Limitation: Data should be kept only as long as necessary for the specified purpose. Retention policies are crucial.
• Integrity and Confidentiality (Security): Data must be processed securely to prevent unauthorized access, loss, or destruction. This relates heavily to Security Best Practices.
• Accountability: The organization is responsible for demonstrating compliance with these principles. This includes maintaining records of data processing activities.

Why is GDPR Relevant to a MediaWiki Installation?

Even if your MediaWiki installation isn't directly commercial, GDPR likely applies if it processes the personal data of individuals within the EEA or UK. "Personal data" is broadly defined and includes any information relating to an identified or identifiable natural person ("data subject"). This can include:

• User Accounts: Usernames, email addresses, IP addresses, and any other information provided during account creation.
• Edit History: While seemingly innocuous, edit histories can reveal personal information (e.g., location based on IP address, interests based on editing patterns).
• Talk Pages & Contributions: Discussions and contributions can contain personal data.
• Logs: Server logs, access logs, and audit logs may contain IP addresses and other identifying information.
• Uploaded Files: Files uploaded to the wiki might contain personal data.
• Cookies: If your wiki uses cookies (even for basic functionality), you need to comply with cookie regulations. See Cookie Policy.
• Forms: Any forms used on the wiki, such as contact forms, collect personal data.

Failure to comply with GDPR can result in significant fines – up to €20 million or 4% of annual global turnover, whichever is higher. More importantly, it can damage your reputation and erode user trust.

Roles and Responsibilities

Within a MediaWiki environment, several roles have GDPR-related responsibilities:

• Wiki Administrator: Responsible for the overall GDPR compliance of the wiki, including implementing technical and organizational measures. This includes configuring privacy settings, managing user rights, and responding to data subject requests. See Administrator Guide.
• Wiki User: Users have a responsibility to be mindful of the personal data they share on the wiki and to respect the privacy of others.
• Data Protection Officer (DPO): If your organization is required to appoint a DPO (based on the size and nature of your data processing activities), they will oversee GDPR compliance across all areas, including the wiki.

Implementing GDPR Compliance in MediaWiki

Here's a breakdown of practical steps you can take to make your MediaWiki installation GDPR compliant:

1. Data Mapping & Audit:

• Identify Personal Data: Create a comprehensive list of all personal data processed by your wiki (as outlined above).
• Document Processing Activities: Document *how* each type of personal data is collected, used, stored, and shared. This is often referred to as a Record of Processing Activities (RoPA). Tools like PrivacyXL ([1](https://www.privacyxl.com/)) can assist with this.
• Assess Legal Basis: Determine the legal basis for processing each type of personal data (e.g., consent, legitimate interest, contract). Legitimate interest requires a careful balancing test. See ICO guidance ([2](https://ico.org.uk/for-organisations/data-protection-guide/)).

2. Technical Measures:

• Enable Secure Connections (HTTPS): Essential for protecting data in transit. Ensure your wiki is served over HTTPS.
• IP Address Masking/Anonymization: Consider masking or anonymizing IP addresses in logs to reduce the risk of identifying individuals. Extensions like `IPAnonymize` ([3](https://www.mediawiki.org/wiki/Extension:IPAnonymize)) can help.
• Data Encryption: Encrypt sensitive data at rest (e.g., user passwords, potentially sensitive content).
• Access Control: Implement strict access control policies to limit access to personal data to authorized personnel only. Utilize MediaWiki's built-in user rights management system.
• Regular Security Audits: Conduct regular security audits to identify and address vulnerabilities. Tools like OWASP ZAP ([4](https://owasp.org/www-project-zap/)) can assist.
• Database Backups: Ensure database backups are stored securely and are only accessible to authorized personnel. Consider encryption for backups.
• Cookie Consent Management: If your wiki uses cookies, implement a cookie consent banner that allows users to opt-in or opt-out of non-essential cookies. Consider using a cookie consent management platform (CMP) like Cookiebot ([5](https://www.cookiebot.com/)).

3. Organizational Measures:

• Privacy Policy: Create a clear and comprehensive privacy policy that explains how you collect, use, and protect personal data. Make it easily accessible on your wiki. See Privacy Policy Template.
• Terms of Service: Update your terms of service to reflect your GDPR compliance.
• Data Retention Policy: Establish a data retention policy that specifies how long you will keep different types of personal data.
• Data Subject Request Procedures: Develop procedures for handling data subject requests (see below).
• Staff Training: Train all staff (including administrators) on GDPR principles and procedures. Resources like GDPR Training ([6](https://www.gdprtraining.eu/)) can be helpful.

4. Data Subject Rights & Handling Requests:

GDPR grants individuals several rights regarding their personal data. You must have procedures in place to handle these requests:

• Right to Access: Individuals have the right to know what personal data you hold about them.
• Right to Rectification: Individuals have the right to have inaccurate data corrected.
• Right to Erasure (Right to be Forgotten): Individuals have the right to have their personal data deleted under certain circumstances.
• Right to Restriction of Processing: Individuals have the right to restrict the processing of their personal data.
• Right to Data Portability: Individuals have the right to receive their personal data in a portable format.
• Right to Object: Individuals have the right to object to the processing of their personal data.

Handling Requests in MediaWiki:

• Identify the Data: Locate all instances of the data subject's personal data within the wiki (user account, edit history, talk pages, logs, etc.).
• Verify Identity: Verify the identity of the requester to prevent unauthorized access.
• Respond Promptly: Respond to requests within one month (unless an extension is justified).
• Document Everything: Keep a record of all data subject requests and your responses.
• Consider Deletion vs. Anonymization: For erasure requests, consider whether data can be anonymized instead of deleted to preserve historical information.

Useful Extensions

Several MediaWiki extensions can assist with GDPR compliance:

• UserMerge: Allows administrators to merge user accounts, which can be useful for consolidating data. ([7](https://www.mediawiki.org/wiki/Extension:UserMerge))
• BlockLog: Provides a detailed log of user blocks, which can be helpful for demonstrating accountability. ([8](https://www.mediawiki.org/wiki/Extension:BlockLog))
• ConfirmEdit: Helps prevent vandalism and abuse, which can reduce the risk of personal data being maliciously published. ([9](https://www.mediawiki.org/wiki/Extension:ConfirmEdit))
• AbuseFilter: A powerful tool for detecting and preventing abusive behavior, including the posting of personal data. ([10](https://www.mediawiki.org/wiki/Extension:AbuseFilter))
• GDPR Compliance (Beta): A developing extension aiming to provide more specific GDPR-related features. ([11](https://github.com/MediaWiki/extensions/tree/master/GDPRCompliance))
