Data Protection

What Is Data Security?

A small-business guide to data classification, access control, encryption, monitoring, backup, and recovery.

Part of the Data Protection & Recovery Learning Center

Data security protects information from unauthorized access, alteration, loss, and disclosure. Effective programs combine people, policies, technology, and recovery planning.

Why it matters

What business leaders should understand

Sensitive client, employee, financial, and operational data exists across email, cloud applications, endpoints, backups, and vendors. Protecting only the office server leaves important gaps.

The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.

Learn how Meta IT Pro can help with backup and disaster recovery.
