Classification Matrix: Manage sensitive documents effectively

What is a classification matrix? 📊

A classification matrix is a model that organizations use to classify documents according to their sensitivity and security needs. This often involves the use of a BIV classification, which stands for Availability, Integrity and Confidentiality. With the BIV classification, you assess:

• Availability: How important is it that a document is always accessible?
• Integrity: How critical is it that the content of a document remains accurate and unchanged?
• Confidentiality: How sensitive is the information and who is allowed to see it?

These BIV factors form the basis for determining the classification of a document.

 

 

Why a classification matrix is essential 🌟

Proper classification prevents errors and increases the security of your data.
Here are some advantages:

• 🔐 Protects sensitive data: Restrict access to confidential information.
• 📋 Ensures consistency: Everyone in the organization knows which rules apply to which documents.
• ⚡ Increases efficiency: Less time spent searching or doubting how to handle a document.
• ✅ Compliance with legislation: Think AVG, GDPR or other data security regulations.

 

 

This is how to create a classification matrix: A step-by-step plan 🛠️

Creating a good classification matrix does not have to be complicated. Just follow this roadmap:

1. Identify the types of data 🗂️
   • Analyze what types of information occur within your organization (e.g., HR files, customer contracts, emails).
2. Determine sensitivity levels 🔒
   • Create categories such as:
     • Public 🌍 (accessible to all).
     • Internal 📁 (employees only).
     • Confidential 🔐 (for specific teams only).
     • Highly confidential 🚨 (accessible only to management or security).
3. Define access levels 🚦
   • Establish who has access to each type of document.
4. Establish policies and procedures 🖋️
   • Make sure employees know how to label and secure documents.
5. Implement technology 💻
   • Use tools such as Microsoft Purview, Azure Information Protection, or other Data Loss Prevention (DLP) tools to implement classification automatically.
6. Train your employees 🎓
   • Make sure everyone is aware of the classification policy.

 

 

 

Tools and technology for document classification 🛡️

The right technology can make a world of difference. Some popular tools:

• Microsoft Purview: For data classification and regulatory compliance.
• Azure Information Protection: Add labels to sensitive files and control who can access them.
• Data Loss Prevention (DLP) tools: Detect and prevent accidental sharing of sensitive data.

 

 

Tips for successful implementation 🚀

• Start small: Start with a limited pilot to test the process.
• Monitor and improve: Provide regular audits to see if policies are effective.
• Engage your team: Make it accessible and user-friendly so that employees really use the classification matrix.
