Data Classification Policy
1. Purpose
This Data Classification Policy outlines the framework for classifying data collected and processed by Yazi. It aims to ensure that all company data is appropriately classified and handled according to its level of sensitivity and corresponding requirements for confidentiality, integrity, and availability.
2. Classification Levels and Data Types
Public (Level 1)
Data that is intended for public release.
Includes marketing materials, published survey results, or any data that is not deemed sensitive.
Public data may be shared via company website, press releases, or social media.
Internal (Level 2)
Internal operational data not meant for public release.
Includes internal policies, employee schedules, or nonsensitive survey data.
Should be shared internally using company-sanctioned methods such as company email or internal document management systems. It should not be shared on public platforms, like personal social media accounts.
Confidential (Level 3)
Sensitive data that could harm individuals or Yazi if disclosed.
Includes personal data of survey respondents, HR records, and customer information.
Sharing should only be done through secure channels, such as encrypted emails or secure file transfer protocols. Confidential data must not be shared over messaging apps like WhatsApp or unsecured email.
Highly Confidential (Level 4)
Highly sensitive data that would cause severe damage if disclosed.
Includes proprietary research, legal documents, trade secrets, and detailed personal information.
Strictly controlled access on a need-to-know basis. Distribution should be done through encrypted databases with access logging. No external sharing without explicit authorization.
