Mobile developers should be trained on credential handling, local data storage, authentication and authorization, secure communication, input and output validation, third party SDK risk and binary protections. The OWASP Mobile Top 10 2024 covers all of these, and it is a sound outline for a mobile specific training track.
Why mobile needs its own track
A mobile app runs on a device the developer does not control. Users can install it on a rooted phone, inspect its traffic and unpack its binary. Server developers can assume the code stays on their side of the wall. Mobile developers cannot.
That changes what to teach. Hard coded keys, tokens written to plain storage and trust in the client are the mistakes that matter most, and a generic web course barely touches them.
The OWASP Mobile Top 10 as an outline
The 2024 list has ten risks, M1 to M10:
| Id | Risk |
|---|---|
| M1 | Improper Credential Usage |
| M2 | Inadequate Supply Chain Security |
| M3 | Insecure Authentication/Authorization |
| M4 | Insufficient Input/Output Validation |
| M5 | Insecure Communication |
| M6 | Inadequate Privacy Controls |
| M7 | Insufficient Binary Protections |
| M8 | Security Misconfiguration |
| M9 | Insecure Data Storage |
| M10 | Insufficient Cryptography |
You do not need ten separate sessions. Group them into four.
- Secrets and storage (M1, M9, M10): what may live on the device, where, and how it is protected.
- Identity and traffic (M3, M5): who is the user, how does the server know, and how does data travel.
- Code and components (M2, M4, M7, M8): third party libraries, validating what the app receives, and what an attacker learns from the binary.
- Privacy (M6): what data the app collects, why, and who sees it.
Exercises that stick
- Give developers a built app and ask them to find anything sensitive in the package without running it. Most are surprised.
- Ask them to route the app through an intercepting proxy on a test device and read what it sends.
- Have them review the dependency list of an app and mark each library as needed, unknown or removable.
- Ask: which checks exist only in the app, and what happens if someone skips them? Anything the server does not also enforce is a suggestion, not a control.
Keep the platform detail current
Storage and permission behaviour changes with each major OS release. Do not freeze OS specific advice in slides that nobody revisits. Point developers at the current platform documentation and keep your own material focused on principles and on your own code.
Try it yourself
Click through it at your own pace, or open it full screen.
Look at how much of an app is code someone else wrote. That is the M2 conversation in one screen.
Where Safeguard fits
Safeguard does not offer training courses. It does offer dependency and SBOM scanning, which gives mobile teams an honest inventory of the libraries inside their apps, plus iOS and Android apps for following findings on the go. A free scan is at gold.safeguard.sh/scan.
Quick check
Do mobile developers need different training from backend developers?
Partly. Many principles overlap, but mobile adds device side storage, binary exposure and client trust issues that backend training rarely covers.
Is the OWASP Mobile Top 10 a compliance requirement?
It is a community awareness list, not a regulation. Use it to structure learning, and check your own contractual and regulatory obligations separately.
