Understanding Data Classification at Alpha Development

Proper handling of company data is everyone’s responsibility. This guide explains how to classify and handle different types of information.

Data Classification Levels

• Public: Information that can be shared externally (marketing materials, press releases)
• Internal: Information for internal use only (company policies, internal announcements)
• Confidential: Sensitive information restricted to specific teams (project financials, contracts)
• Highly Confidential: Critical information with strict access control (strategic plans, legal documents)

Handling Guidelines

• Store confidential documents in SharePoint with restricted permissions
• Do not send sensitive information via unencrypted email
• Use OneDrive’s Personal Vault for highly sensitive personal files
• Lock your screen when stepping away from your computer (Windows Key + L)
• Shred physical documents containing sensitive information
• Report any data breaches or suspected leaks to IT immediately

Email Best Practices

• Double-check recipients before sending emails with attachments
