As of July 2023, Android's operating system share will reach 40.15%. As a No.1 operating system, it must not only ensure ease of use, but also better ensure security. This article will briefly introduce Android's security measures, and will introduce detailed introductions in different topics later.
As an open system, Android provides an open source platform and application environment suitable for mobile devices. Its software architecture is shown below. The bottom layer uses Linux, and the upper layer adopts a layered architecture. The components of each layer assume that the components below have taken appropriate security measures.
Google provides a series of security services on Android devices, mainly including the following aspects.
| Google play offers community moderation | Application license verification, security scanning and other services |
|---|---|
| Android update service via OTA | Provide device feature and security updates. |
| App Service Provides Cloud Functions | Such as data and settings backup security features |
| verify app scan app | Warn or block when installing |
| SafetyNet | Privacy-preserving intrusion detection system |
| SafetyNet Attestation | Verify device security compatibility |
| device manager | For finding lost or stolen devices |
In order to ensure the security of the Android system is guaranteed, Google has proposed a standard security plan operating process.
1) Design Review: Create a large number of configurable security models and designs early in the development lifecycle.
2) Penetration testing and code review: Components created during development and open source components are subject to strict security reviews.
3) Open source and community audits: Allows for extensive security audits by anyone interested.
4) Incident response: specify a comprehensive security response process.
5) Monthly Security Updates: Provides regular security updates.
The above is the overall structure provided by Android for device security. Specific to the implementation level, it will provide corresponding solutions from startup to application.

If you want to become an architect or want to break through the 20-30K salary range, then don't be limited to coding and business, but you must be able to select models, expand, and improve programming thinking. In addition, a good career plan is also very important, and the habit of learning is very important, but the most important thing is to be able to persevere. Any plan that cannot be implemented consistently is empty talk.
If you have no direction, here I would like to share with you a set of "Advanced Notes on the Eight Major Modules of Android" written by the senior architect of Ali, to help you organize the messy, scattered and fragmented knowledge systematically, so that you can systematically and efficiently Master the various knowledge points of Android development.
Compared with the fragmented content we usually read, the knowledge points of this note are more systematic, easier to understand and remember, and are arranged strictly according to the knowledge system.

1. Interview collection
2. Source code analysis collection
3. The collection of open source frameworks
