操作场景
安全组规则设置不当会造成严重的安全隐患，例如安全组规则对特定端口的访问不做限制。您可以通过修改安全组中不合理的安全组规则，保证云服务器实例的网络安全。本文指导您如何修改安全组规则。
前提条件
操作步骤
1. 登录 安全组控制台，进入安全组管理页面。
2. 在安全组管理页面，选择地域，找到需要修改规则的安全组。
3. 在需要修改规则的安全组行中，单击操作列的修改规则，进入安全组规则页面。
4. 在安全组规则页面，根据需要修改安全组规则所属的方向（入站/出站），单击入站/出站规则页签。
5. 找到需要修改的安全组规则，单击操作列的编辑，即可对已有规则进行修改。
说明：
修改安全组规则后无需重启云服务器。
