GCP Terraform Misconfiguration: Compute Engine Serial Console Enabled
Abstract
Terraform 配置设置了一个启用交互式串行控制台访问权限的 Compute Engine 实例。
Explanation
未能阻止不需要的网络流量会扩大云服务的攻击面。向公众开放的服务会受到恶意实体近乎持续的扫描和探测。
默认情况下,禁用 Compute Engine 实例的串行端口的控制台访问权限。启用串行控制台访问权限可能会允许攻击者从任意 IP 地址连接到 Compute Engine 实例,因为串行端口不支持基于 IP 的访问限制。
示例 1:以下 Terraform 配置通过将
