钉钉 AI 客服：安全加固完全指南

安全是 AI 客服的生命线。

一、安全威胁

威胁	风险	等级
SQL 注入	数据泄露	高
XSS 攻击	信息窃取	高
API 滥用	服务中断	中
数据泄露	隐私问题	高

二、输入验证

2.1 SQL 注入防护

// ❌ 不安全的查询
const sql = `SELECT * FROM users WHERE id = ${id}`;

// ✅ 安全的查询
const sql = 'SELECT * FROM users WHERE id = ?';
await db.query(sql, [id]);

2.2 XSS 防护

const validator = require('validator');

function sanitize(input) {
  return validator.escape(input);
}

// 使用
const safeMessage = sanitize(userMessage);

三、API 安全

3.1 速率限制

const rateLimit = require('express-rate-limit');

app.use('/api/', rateLimit({
  windowMs: 60 * 1000,
  max: 100,
  message: '请求过于频繁'
}));

3.2 API Key 验证

app.use((req, res, next) => {
  const key = req.headers['x-api-key'];
  
  if (!key || !validateKey(key)) {
    return res.status(401).json({ error: '无效 API Key' });
  }
  
  next();
});

四、数据加密

4.1 传输加密

// 强制 HTTPS
app.use((req, res, next) => {
  if (!req.secure) {
    return res.redirect(`https://${req.headers.host}${req.url}`);
  }
  next();
});

4.2 存储加密

const crypto = require('crypto');

function encrypt(text) {
  const iv = crypto.randomBytes(16);
  const cipher = crypto.createCipheriv('aes-256-cbc', SECRET_KEY, iv);
  let encrypted = cipher.update(text, 'utf8', 'hex');
  encrypted += cipher.final('hex');
  return iv.toString('hex') + ':' + encrypted;
}

function decrypt(text) {
  const [ivHex, encrypted] = text.split(':');
  const iv = Buffer.from(ivHex, 'hex');
  const decipher = crypto.createDecipheriv('aes-256-cbc', SECRET_KEY, iv);
  let decrypted = decipher.update(encrypted, 'hex', 'utf8');
  decrypted += decipher.final('utf8');
  return decrypted;
}

五、访问控制

5.1 RBAC 权限

const roles = {
  admin: ['read', 'write', 'delete'],
  editor: ['read', 'write'],
  viewer: ['read']
};

function checkPermission(user, action) {
  return roles[user.role].includes(action);
}

5.2 IP 白名单

const ALLOWED_IPS = ['192.168.1.0/24', '10.0.0.0/8'];

app.use((req, res, next) => {
  const ip = req.ip;
  
  if (!isAllowedIP(ip)) {
    return res.status(403).json({ error: '访问被拒绝' });
  }
  
  next();
});

六、安全头

const helmet = require('helmet');

app.use(helmet());
app.use(helmet.contentSecurityPolicy({
  directives: {
    defaultSrc: ["'self'"],
    scriptSrc: ["'self'"]
  }
}));

七、日志审计

function audit(action, user, details) {
  console.log(JSON.stringify({
    timestamp: new Date().toISOString(),
    action,
    user: user.id,
    details
  }));
}

// 使用
audit('DELETE_FAQ', req.user, { faqId: id });
