Overview
本技能提供OpenHarmony分布式业务安全代码检视的专业指导,包含18条安全设计规则和对应的检视要点。当检视分布式系统代码安全性时,在通用网络安全规则基础上,使用这些规则进行加强检视。

Code Review Workflow
Step 1: Understand the Code Context
首先理解代码的业务场景和所在模块:
-
识别关键模块: 确定代码是否涉及以下模块
- 分布式设备管理
- 分布式软总线
- 其他需要分布式能力的模块
-
识别业务类型: 判断是否涉及以下安全敏感业务
- 设备间认证和授权
- 用户敏感数据传输
- 跨设备状态机管理
- 可信关系管理
- 硬件资源访问
-
确定角色: 识别代码是主体侧(客户端)还是客体侧(服务端)
Step 2: Load Security Rules
根据代码涉及的业务类型,加载security_rules.md中对应的规则:
快速索引关键词:
- 跨设备传输 → Rules 3, 8, 15, 17
- 状态机 → Rule 2
- 授权/鉴权 → Rules 1, 5, 6, 8, 12
- PIN码/秘钥 → Rules 3, 8, 9, 10
- 资源申请 → Rule 4
- 权限配置 → Rules 7, 13
- 开关标记 → Rule 14
- 用户切换 → Rule 16
- 兼容代码 → Rule 18
Step 3: Review Against Security Rules
对每个适用的安全规则,执行以下检视:
-
定位相关代码: 使用Grep搜索关键模式
Grep patterns examples: - "auth", "authorize", "permission" for authorization checks - "PIN", "secret", "key" for sensitive data - "state", "status" for state machine - "random", "generate" for secret generation -
检查实现细节:
- 对照规则中的Check points逐项检查
- 查找潜在的违规模式
- 识别缺失的安全措施
-
记录发现:
- 标记违规代码位置 (file:line)
- 说明违反的具体规则
- 提供修复建议
Step 4: Apply General Security Best Practices
除了OpenHarmony特定规则外,还需检查通用安全实践:
- 输入验证: 所有外部输入是否经过验证
- 错误处理: 敏感操作是否有适当的错误处理
- 日志安全: 是否记录了敏感信息
- 资源管理: 是否有资源泄漏风险
Step 5: Generate Review Report
生成结构化的安全检视报告,包含:
- 执行摘要: 发现的严重安全问题数量和等级
- 违规清单: 按严重程度排序的违规项
- 规则映射: 每个问题对应的安全规则
- 修复建议: 具体的代码修改建议
Common Violation Patterns
Pattern 1: Client-controlled Authorization (违反规则1)
Bad Example:
// 客体侧直接使用主体侧传入的标志控制弹框
void handleAuthRequest(bool showPopup) {
if (!showPopup) {
// 直接跳过授权弹框
grantAccess();
}
}
Correct Approach:
// 客体侧独立决策是否需要授权
void handleAuthRequest() {
if (isSystemBusinessAndRegistered()) {
// 已注册的免授权业务
grantAccess();
} else {
// 默认必须弹框
showAuthorizationDialog();
}
}
Pattern 2: Plaintext Sensitive Data (违反规则3)
Bad Example:
// 明文传输PIN码
message.pin_code = userPin;
sendToRemote(message);
Correct Approach:
// 加密后传输
encryptedPin = encryptPin(userPin, sessionKey);
message.encrypted_pin = encryptedPin;
sendToRemote(message);
Pattern 3: Custom Trust Verification (违反规则8)
Bad Example:
// 自行比对账号信息判断可信关系
bool isTrusted() {
return localAccount == remoteAccount;
}
Correct Approach:
// 依赖HiChain查询
bool isTrusted() {
CredentialType type = HiChain.queryCredentialType(remoteDevice);
return type == CredentialType.SAME_ACCOUNT;
}
Pattern 4: Insecure Switch Defaults (违反规则14)
Bad Example:
// 默认值放通
bool enableSecurityCheck = true; // 默认启用
Correct Approach:
// 默认值禁用
bool enableSecurityCheck = false; // 默认禁用,需显式启用
Security Rule Categories

3. Trust Management
- Rule 7: Trusted Relationship Lifecycle Minimization
- Rule 8: Trusted Relationship Verification
- Rule 9: Trusted Relationship Persistence Timing
- Rule 15: Device Legitimacy Verification
- Rule 16: User Isolation for Distributed Trust
4. State Machine & Process Control
- Rule 2: State Machine Context Validation
5. Resource Management

Example Review Session
User request: "检视这段分布式设备管理代码的安全性"
Review process:
- Load security rules → Read security_rules.md
- Identify relevant rules → Rules 1, 2, 7, 8, 9, 11 (设备管理相关)
- Search code patterns → Grep for authorization, trust, state machine
- Check each rule:
- ✓ Rule 1: 授权流程是否在客体侧独立控制
- ✗ Rule 2: 发现状态机未校验上下文
- ✓ Rule 7: 可信关系生命周期管理正确
- ✗ Rule 8: 发现自定义可信判断逻辑
- Generate report → 列出违规点和修复建议
Tips
- Start with keywords: 使用security_rules.md中的关键词快速定位可疑代码
- Check both sides: 分布式业务需要同时检查主体侧和客体侧代码
- Verify complete flows: 跟踪完整的业务流程,不要只检查单个函数
- Consider edge cases: 检查错误处理、超时、重试等边界场景
- Review logging: 确保日志中不泄露敏感信息

- Detailed Rules: See security_rules.md for complete rule descriptions and check points
- Quick Reference: Use keyword mapping at the end of security_rules.md for fast rule lookup
