简介

设备风险管理平台(SecurityGuard,简称SG)向应用提供风险分析能力,包括root检测,设备完整性检测,物理真机检测等功能。 SG模块可以分为如下三大部分:

  • SG 接口层:提供SG API供应用调用。
  • SG 基础服务层:实现SG数据管理、模型管理、配置管理、采集器管理等功能。
  • SG 安全模型: 1)越狱检测模型:检测系统是否处于越狱的状态,比如通过分析系统调用表、内核代码段是否会破坏来判断是越狱状态; 2)设备完整性检测模型:检测设备是否处于完整的未被修改的状态,比如通过分析boot状态是否有异常、设备是否被解锁来判断设备完整性状态; 3)物理机检测模型:检测当前设备是物理机或模拟器;

编译构建

以rk3568为例,编译命令如下:

./build.sh --product-name rk3568 --build-target security_guard --ccache

事件ID编码规则

使用事件ID编码的方式对数据做分类,编码原则如下:

  • 按照OH系统、厂商系统(基于OH定制的系统)两个维度定义编码;
  • OH系统的编码随社区独立演进,代码合入社区时重新分配编码;
  • 厂商系统的编码有厂商自定义演进,不与社区编码重叠

事件ID编码分为三部分组成,每部分采用三位16进制表示:子系统编码 + 部件编码 + 事件编码

  • 区分OH系统与厂商系统的子系统、部件、事件编码范围: OH系统使用: 0x800 – 0xFFF 厂商系统使用: 0x000 – 0x7FF
  • 新增编码从小到大自然增长;

事件ID示例:

OH系统(以82c800801编码为例):
82c :OH a子系统, 800:OH b部件、 801:OH c事件

厂商系统(以1002003编码为例):
1 :厂商 x子系统, 002 :厂商 y部件、 003 :厂商 z事件

模型编码规则:

使用易于开发者使用的字符串标识模型,提供两种分类: 1、Vender厂商预置的,由OpenHarmory定义,由厂商做差异化的能力; 2、EDR类App下发模型,由App做自定义模型的标识;
