MySQL安全加固十大硬核操作技术文章大纲
1. 修改默认端口与限制访问
- 将默认3306端口改为非标准端口，减少扫描风险
- 通过防火墙或安全组限制仅允许可信IP访问MySQL服务
- 禁用远程root登录，仅允许本地或特定用户连接
2. 强化账户与密码策略
- 删除匿名账户和测试数据库（如test库）
- 设置复杂密码策略：长度≥12位，包含大小写字母、数字、特殊字符
- 定期轮换密码，避免长期使用同一密码
3. 最小权限原则
- 为每个应用创建独立账户，仅授予必要权限（避免ALL PRIVILEGES）
- 限制FILE、PROCESS、SUPER等高危权限的使用
- 使用REVOKE回收不必要的权限
4. 启用SSL/TLS加密传输
- 配置MySQL支持SSL证书，强制客户端加密连接
- 验证证书有效性，避免中间人攻击
- 监控未加密连接的尝试行为
5. 审计与日志监控
- 开启MySQL审计插件（如audit_log）记录关键操作
- 定期分析错误日志、慢查询日志和二进制日志
- 使用工具如OSEC或Percona Audit Plugin增强审计
6. 数据脱敏与加密
- 对敏感字段（如手机号、身份证号）使用AES加密存储
- 应用层实现动态数据脱敏（如SUBSTRING或CONCAT部分显示）
- 考虑透明数据加密（TDE）保护表空间文件
7. 防止SQL注入
- 强制使用预处理语句（Prepared Statements）
- 对用户输入进行严格的校验和转义
- 禁用动态SQL拼接，避免EXECUTE IMMEDIATE滥用
8. 系统级加固
- 以非root用户运行MySQL服务（如专用mysql账户）
- 限制MySQL目录权限（如chmod 750 /var/lib/mysql）
- 关闭不必要的系统功能（如skip_symbolic_links防止符号链接攻击）
9. 定期备份与恢复验证
- 使用mysqldump或xtrabackup实现全量/增量备份
- 备份文件加密存储，并测试恢复流程有效性
- 制定RTO（恢复时间目标）和RPO（恢复点目标）策略
10. 漏洞管理与补丁更新
- 订阅MySQL官方安全公告（如Oracle Critical Patch Updates）
- 定期升级至最新稳定版本或应用安全补丁
- 使用漏洞扫描工具（如OpenVAS）检测潜在风险
附加：安全工具推荐
- 漏洞扫描：Nessus、Qualys
- 配置检查：MySQL Enterprise Firewall、Percona Toolkit
- 监控告警：Prometheus + Grafana + AlertManager
