AWS Ansible Misconfiguration: RDS Publicly Accessible

YAML

Abstract

Ansible 任务定义了具有公共访问权限的 Amazon RDS 实例。

Explanation

可公开访问的 Amazon RDS 实例不必要地扩大了组织的攻击面。向公众开放的服务会受到攻击者近乎持续的扫描和探测。

示例 1：以下 Ansible 任务设置了具有公共访问权限的 RDS 实例，因为 publicly_accessible 设置为 true。


- name: createdb
  community.aws.rds_instance:
    db_instance_identifier: test-db
    engine: aurora
    instance_type: db.t2.small
    username: "{{ username }}"
    password: "{{ password }}"
    cluster_id: test-cluster
    publicly_accessible: true

AWS CloudFormation Misconfiguration: Improper EC2 Network Access Control

JSON
YAML

Abstract

该模板定义了访问限制不足的安全组。

Explanation

宽松的访问配置会无端暴露系统并扩大组织的攻击面。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。

当发现并发布某项公开服务的零日漏洞（例如 Heartbleed）时，尤其容易出现问题。攻击者可能会主动追踪和搜索未修补和暴露的系统以进行利用。
