1.2 安全设计原则

# 安全设计原则
security:
  principles:
    - "最小权限原则"
    - "纵深防御"
    - "安全默认配置"
    - "失败安全"
    - "完全中介"
    - "开放设计"
    - "权限分离"
    - "心理可接受性"

二、身份认证与授权

2.1 JWT认证实现

// JWT认证服务
import jwt from 'jsonwebtoken';
import bcrypt from 'bcrypt';

class AuthService {
  private readonly JWT_SECRET = process.env.JWT_SECRET!;
  private readonly JWT_EXPIRES_IN = '24h';
  
  async authenticate(username: string, password: string) {
    // 1. 验证用户
    const user = await this.findUser(username);
    if (!user) {
      throw new Error('用户不存在');
    }
    
    // 2. 验证密码
    const isValid = await bcrypt.compare(password, user.passwordHash);
    if (!isValid) {
      throw new Error('密码错误');
    }
    
    // 3. 生成JWT
    const token = jwt.sign(
      {
        userId: user.id,
        username: user.username,
        roles: user.roles,
        permissions: user.permissions
      },
      this.JWT_SECRET,
      {
        expiresIn: this.JWT_EXPIRES_IN,
        issuer: 'openclaw-auth',
        audience: 'openclaw-api'
      }
    );
    
    // 4. 生成刷新令牌
    const refreshToken = jwt.sign(
      { userId: user.id },
      process.env.REFRESH_TOKEN_SECRET!,
      { expiresIn: '7d' }
    );
    
    return { token, refreshToken, user };
  }
  
  async verifyToken(token: string) {
    try {
      const decoded = jwt.verify(token, this.JWT_SECRET, {
        issuer: 'openclaw-auth',
        audience: 'openclaw-api'
      });
      return decoded;
    } catch (error) {
      throw new Error('令牌无效或已过期');
    }
  }
}

2.2 OAuth2.0集成

// OAuth2.0客户端
import { AuthorizationCode } from 'simple-oauth2';

class OAuth2Client {
  private client: AuthorizationCode;
  
  constructor() {
    this.client = new AuthorizationCode({
      client: {
        id: process.env.OAUTH_CLIENT_ID!,
        secret: process.env.OAUTH_CLIENT_SECRET!
      },
      auth: {
        tokenHost: process.env.OAUTH_TOKEN_HOST!,
        authorizePath: process.env.OAUTH_AUTHORIZE_PATH!,
        tokenPath: process.env.OAUTH_TOKEN_PATH!
      }
    });
  }
  
  async getAuthorizationUrl() {
    const authorizationUri = this.client.authorizeURL({
      redirect_uri: process.env.OAUTH_REDIRECT_URI!,
      scope: 'openid profile email',
      state: this.generateState()
    });
    
    return authorizationUri;
  }
  
  async getToken(code: string) {
    const tokenParams = {
      code,
      redirect_uri: process.env.OAUTH_REDIRECT_URI!,
      scope: 'openid profile email'
    };
    
    const result = await this.client.getToken(tokenParams);
    return result.token;
  }
}

三、访问控制

3.1 RBAC权限控制

// RBAC权限管理
class RBACService {
  private roles = new Map();
  private permissions = new Map();
  
  constructor() {
    this.initializeRoles();
  }
  
  private initializeRoles() {
    // 定义角色
    this.roles.set('admin', {
      name: '管理员',
      permissions: [
        'workflow:*',
        'user:*',
        'model:*',
        'tool:*',
        'system:*'
      ]
    });
    
    this.roles.set('developer', {
      name: '开发者',
      permissions: [
        'workflow:read',
        'workflow:write',
        'model:read',
        'model:execute',
        'tool:read',
        'tool:execute'
      ]
    });
    
    this.roles.set('viewer', {
      name: '查看者',
      permissions: [
        'workflow:read',
        'model:read',
        'tool:read'
      ]
    });
  }
  
  async checkPermission(user: User, resource: string, action: string) {
    const userRoles = user.roles || [];
    
    for (const roleName of userRoles) {
      const role = this.roles.get(roleName);
      if (!role) continue;
      
      // 检查通配符权限
      if (role.permissions.includes(`${resource}:*`)) {
        return true;
      }
      
      // 检查具体权限
      if (role.permissions.includes(`${resource}:${action}`)) {
        return true;
      }
    }
    
    return false;
  }
  
  async enforce(user: User, resource: string, action: string) {
    const hasPermission = await this.checkPermission(user, resource, action);
    if (!hasPermission) {
      throw new Error('权限不足');
    }
  }
}

3.2 ABAC属性访问控制

// ABAC策略引擎
class ABACEngine {
  private policies = [];
  
  async evaluate(user: User, resource: Resource, action: string) {
    for (const policy of this.policies) {
      const result = await this.evaluatePolicy(policy, user, resource, action);
      if (result !== undefined) {
        return result;
      }
    }
    
    return false; // 默认拒绝
  }
  
  private async evaluatePolicy(policy, user, resource, action) {
    // 评估条件
    const conditions = policy.conditions || [];
    for (const condition of conditions) {
      const result = await this.evaluateCondition(condition, user, resource);
      if (!result) {
        return undefined; // 条件不满足,跳过此策略
      }
    }
    
    // 检查操作
    if (policy.actions.includes(action) || policy.actions.includes('*')) {
      return policy.effect === 'allow';
    }
    
    return undefined;
  }
  
  private async evaluateCondition(condition, user, resource) {
    switch (condition.type) {
      case 'time':
        return this.evaluateTimeCondition(condition);
      case 'location':
        return this.evaluateLocationCondition(condition, user);
      case 'resource':
        return this.evaluateResourceCondition(condition, resource);
      default:
        return false;
    }
  }
}

四、数据安全

4.1 数据加密

// 数据加密服务
import crypto from 'crypto';

class EncryptionService {
  private readonly algorithm = 'aes-256-gcm';
  private readonly key: Buffer;
  
  constructor() {
    // 从环境变量获取密钥
    const keyString = process.env.ENCRYPTION_KEY!;
    this.key = crypto.scryptSync(keyString, 'salt', 32);
  }
  
  encrypt(text: string): EncryptedData {
    const iv = crypto.randomBytes(16);
    const cipher = crypto.createCipheriv(this.algorithm, this.key, iv);
    
    let encrypted = cipher.update(text, 'utf8', 'hex');
    encrypted += cipher.final('hex');
    
    const authTag = cipher.getAuthTag();
    
    return {
      encrypted,
      iv: iv.toString('hex'),
      authTag: authTag.toString('hex'),
      algorithm: this.algorithm
    };
  }
  
  decrypt(encryptedData: EncryptedData): string {
    const iv = Buffer.from(encryptedData.iv, 'hex');
    const authTag = Buffer.from(encryptedData.authTag, 'hex');
    
    const decipher = crypto.createDecipheriv(
      this.algorithm, 
      this.key, 
      iv
    );
    
    decipher.setAuthTag(authTag);
    
    let decrypted = decipher.update(encryptedData.encrypted, 'hex', 'utf8');
    decrypted += decipher.final('utf8');
    
    return decrypted;
  }
  
  // 哈希函数
  async hashPassword(password: string): Promise<string> {
    const salt = await bcrypt.genSalt(10);
    return bcrypt.hash(password, salt);
  }
}

4.2 数据脱敏

// 数据脱敏服务
class DataMaskingService {
  private maskingRules = {
    email: (email: string) => {
      const [local, domain] = email.split('@');
      const maskedLocal = local.charAt(0) + '***' + local.charAt(local.length - 1);
      return `${maskedLocal}@${domain}`;
    },
    
    phone: (phone: string) => {
      return phone.replace(/(\d{3})\d{4}(\d{4})/, '$1****$2');
    },
    
    idCard: (idCard: string) => {
      return idCard.replace(/(\d{6})\d{8}(\w{4})/, '$1********$2');
    },
    
    bankCard: (card: string) => {
      return card.replace(/(\d{4})\d{8}(\d{4})/, '$1****$2');
    }
  };
  
  maskData(data: any, rules: string[]): any {
    if (Array.isArray(data)) {
      return data.map(item => this.maskData(item, rules));
    }
    
    if (typeof data === 'object' && data !== null) {
      const masked = { ...data };
      for (const [key, value] of Object.entries(masked)) {
        if (rules.includes(key)) {
          const masker = this.maskingRules[key];
          if (masker && typeof value === 'string') {
            masked[key] = masker(value);
          }
        }
      }
      return masked;
    }
    
    return data;
  }
}

五、API安全

5.1 API安全中间件

// API安全中间件
class APISecurityMiddleware {
  static async authenticate(req, res, next) {
    try {
      const authHeader = req.headers.authorization;
      if (!authHeader) {
        return res.status(401).json({ error: '未提供认证令牌' });
      }
      
      const token = authHeader.replace('Bearer ', '');
      const decoded = await authService.verifyToken(token);
      
      req.user = decoded;
      next();
    } catch (error) {
      return res.status(401).json({ error: '认证失败' });
    }
  }
  
  static async authorize(permission: string) {
    return async (req, res, next) => {
      try {
        const [resource, action] = permission.split(':');
        await rbacService.enforce(req.user, resource, action);
        next();
      } catch (error) {
        return res.status(403).json({ error: '权限不足' });
      }
    };
  }
  
  static async rateLimit(req, res, next) {
    const clientIp = req.ip;
    const key = `rate_limit:${clientIp}`;
    
    const current = await redis.incr(key);
    if (current === 1) {
      await redis.expire(key, 60); // 60秒窗口
    }
    
    if (current > 100) { // 每分钟100次
      return res.status(429).json({ 
        error: '请求过于频繁',
        retryAfter: 60
      });
    }
    
    next();
  }
}

5.2 输入验证

// 输入验证
import { z } from 'zod';

const workflowSchema = z.object({
  name: z.string()
    .min(1, '工作流名称不能为空')
    .max(100, '工作流名称不能超过100个字符'),
  
  description: z.string()
    .max(500, '描述不能超过500个字符')
    .optional(),
  
  nodes: z.array(
    z.object({
      id: z.string().uuid(),
      type: z.enum(['model', 'tool', 'condition', 'loop']),
      config: z.record(z.any())
    })
  ).min(1, '至少需要一个节点'),
  
  edges: z.array(
    z.object({
      source: z.string().uuid(),
      target: z.string().uuid(),
      condition: z.string().optional()
    })
  ),
  
  metadata: z.record(z.any()).optional()
});

class InputValidator {
  static validateWorkflow(input: any) {
    try {
      return workflowSchema.parse(input);
    } catch (error) {
      if (error instanceof z.ZodError) {
        const errors = error.errors.map(err => ({
          path: err.path.join('.'),
          message: err.message
        }));
        throw new ValidationError('输入验证失败', errors);
      }
      throw error;
    }
  }
  
  static sanitizeInput(input: string): string {
    // 防止XSS攻击
    return input
      .replace(/</g, '&lt;')
      .replace(/>/g, '&gt;')
      .replace(/"/g, '&quot;')
      .replace(/'/g, '&#x27;')
      .replace(/\//g, '&#x2F;');
  }
}

    };
    
    // 写入审计日志
    await this.writeToDatabase(logEntry);
    
    // 发送到SIEM系统
    await this.sendToSIEM(logEntry);
    
    // 实时告警
    if (this.isSuspiciousEvent(event)) {
      await this.triggerAlert(event);
    }
  }
  
  private isSuspiciousEvent(event: AuditEvent): boolean {
    const suspiciousPatterns = [
      // 多次失败登录
      event.action === 'login_failed' && event.count > 5,
      
      // 异常时间访问
      event.timestamp.getHours() < 6 || event.timestamp.getHours() > 22,
      
      // 敏感操作
      ['delete', 'update', 'export'].includes(event.action) && 
      ['user', 'workflow', 'model'].includes(event.resource),
      
      // 来自异常IP
      this.isSuspiciousIP(event.ipAddress)
    ];
    
    return suspiciousPatterns.some(pattern => pattern);
  }
}

        }
      });
    }
  }
  
  private async monitorAPIAccess() {
    const apiStats = await this.getAPIStats('1h');
    
    // 检查异常API调用
    for (const [endpoint, stats] of Object.entries(apiStats)) {

          vulnerabilities: vulns
        });
      }
    }
    
    return results;
  }
}

九、合规与标准
