Data Mapping and Data Tracking for Cross-Border Data Flows

The Chinese regulatory authority, Cyberspace Administration of China (CAC) has relaxed the compliance requirements for cross-border data flows. (Of course, in this context its all about the outbound flow of China data!)

Exemptions from data security assessment or regulatory filings are available. This is a significant relief for companies that are non-CIIO (Critical Information Infrastructure Operators) or do not process sensitive personal information. However, it comes with a caveat:

"With fewer [authority] resources needed for handling the filings and approvals of cross-border data transfers, it is possible that [they] may spare more resources on enforcement of the regulations. Therefore, it is important for data processors to conduct data mapping and implement data tracking mechanisms ... for compliance with these new regulations." White & Case, Global Law Firm

??? Data Mapping: Navigating Your Data Landscape

• System / Data Inventory: Creating an inventory is the first step towards effective data protection. Take stock of all the personal information and important data your organisation collects, processes, and stores. This inventory provides a clear picture of your data landscape. Start with what you know and gradually build it out.
• Data Classification: Categorise your data based on sensitivity and regulatory requirements. This classification helps you prioritise protection efforts and determine the appropriate level of security for different types of data. You might need to have a mapping between the Data Classification Schema globally vs. China.
• Data Flow Diagrams: It is impossible to visualize the flow of all data within your organization (It would only reflect the complexities of the real world!). Start with a PoC: Map out its origin, storage locations, and destinations. By understanding how data moves, you can identify potential vulnerabilities and implement appropriate security measures.

?? Data Tracking: Prioritise "Important Data"

• Data Access Logs: Implement logging mechanisms that record access to personal information and important data. Capture details such as who accessed the data, when it was accessed, and for what purpose. This audit trail enhances accountability and aids in incident investigation.
• Data Transfer Auditing: Monitor and track data transfers outside of China. Keep a record of the parties involved, the type of data transferred, and the purpose of the transfer. This auditing process ensures compliance with regulatory requirements and helps detect any unauthorised data flows.
• Encryption and Access Controls: Apply robust encryption techniques and access controls to protect data from unauthorised access and ensure that only authorised individuals can access and transfer sensitive information. These measures add an extra layer of security to your application access controls.

?? Automated Monitoring Tools: Empowering Your Data Protection Strategy

• Data Loss Prevention (DLP) Systems: Deploy DLP that automatically detect and prevent unauthorized data transfers or breaches. These systems generate alerts for any suspicious activities, allowing you to take prompt action to mitigate risks. Again, you need to know where your sensitive data or "important" data is. Deploying DLP everywhere is not possible.
• Intrusion Detection and Prevention Systems (IDPS): Leverage IDPS solutions to monitor network traffic and identify potential data leaks or unauthorized access attempts. These systems act as a proactive defense mechanism, helping you stay one step ahead of potential threats.
• User Activity Monitoring: Utilise specialised software to track data behavior, including data access patterns. This enables you to identify any unusual or non-compliant activities, helping you quickly respond to potential data breaches or insider threats. But only after you have a good idea of where sensitive data is, and the normal behaviour of them

? Where to Start?

There's no unlimited resources; and the business won't be ready for the change from Day 1. Based on my experience, here's where I would start:

?? Assess Your Current State: Evaluate your organization's current data protection practices. Most likely your organisations have identified the critical systems (mostly because it contains sensitive data). This can help you prioritise your efforts and kick-start.

?? Define Clear Goals: Determine what you want to achieve with your data mapping and tracking initiatives. Set clear, measurable goals that align with your organisation's overall data protection strategy. If you don't know what you're aiming at, you'd never hit the target.

?? Engage Key Stakeholders: Involve key stakeholders, including IT, legal, compliance, and data governance teams, in the process. Collaboration and cross-functional alignment are crucial for successful implementation.

?? Seek Expert Guidance: Consult cybersecurity and legal experts to ensure you have a solid understanding of the regulatory landscape and the best practices in data protection. Their insights and guidance will help you make informed decisions.

?? Develop a Roadmap: Create a roadmap that outlines the specific steps, timelines, and responsible parties for implementing data mapping and tracking mechanisms. Break it down into manageable milestones to track progress effectively.

By following these steps, you'll be well on your way to establishing a robust data protection framework through effective data mapping and tracking.
