How Azure Protects Your Mobile App
The 5 layers standing between your app and the database.
What you'll learn
- Why an app talking straight to a database is the bug, not a shortcut
- Why authentication and authorization are two different checks, not one
- Why a private endpoint means the database has no public address to attack

Most people draw this
The app, the database, and a straight line between them — the shape everyone reaches for first, and the shape that gets you breached.
Frequently asked questions
- Why shouldn't a mobile app connect directly to a database?
- A direct line from app to database is also the entire attack surface — no token, no owner check, and (if reachable) a public endpoint an attacker can scan and query. Front Door with WAF, your own API, Microsoft Entra ID and a private endpoint each answer a different question, and removing any one of them removes what the others assumed was already handled.
- What's the difference between authentication and authorization here?
- Authentication (Entra ID) proves who is calling. Authorization is a separate check your API still has to make — deciding that a signed-in user only sees their own rows, typically a WHERE clause rather than middleware. Skipping it is broken object level authorization, OWASP API Security's #1 issue.

These are built for a phone
Every short is drawn at full portrait height, the shape a phone already is. Installed, it opens full-bleed with no address bar across the top — and the whole library reads offline.
