# GDK security overview

> Understand security obligations for GDK licensees, including secure GDK handling, dev hardware storage, Asset Custodian duties, and Microsoft audits.

For full security requirements covering the secure (Partners) GDK, dev hardware, asset custody, confidentiality, breach consequences, and audit, see [Security requirements](/home/onboarding-access/security-requirements).

Key takeaways:

* The secure (Partners) GDK — including dev hardware, software, docs — must **not** be shared
* Store dev hardware in a **secured, locked location**
* Designate an **Asset Custodian**
* Don't discuss the secure GDK with anyone outside your organization
* Microsoft may audit at any time
