Amazon Elastic Compute Cloud（Amazon EC2）的示例 SCP

需要 Amazon EC2 实例以使用特定类型

借助此 SCP，任何不使用 t2.micro 实例类型启动的实例都将被拒绝。

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "RequireMicroInstanceType",
      "Effect": "Deny",
      "Action": "ec2:RunInstances",
      "Resource": [
        "arn:aws:ec2:*:*:instance/*"
      ],
      "Condition": {
        "StringNotEquals": {
          "ec2:InstanceType": "t2.micro"
        }
      }
    }
  ]
}

防止在没有 IMDSv2 的情况下启动 EC2 实例

以下策略限制所有用户在没有 IMDSv2 的情况下启动 EC2 实例。

[
   {
      "Effect":"Deny",
      "Action":"ec2:RunInstances",
      "Resource":"arn:aws:ec2:*:*:instance/*",
      "Condition":{
         "StringNotEquals":{
            "ec2:MetadataHttpTokens":"required"
         }
      }
   },
   {
      "Effect":"Deny",
      "Action":"ec2:RunInstances",
      "Resource":"arn:aws:ec2:*:*:instance/*",
      "Condition":{
         "NumericGreaterThan":{
            "ec2:MetadataHttpPutResponseHopLimit":"3"
         }
      }
   },
   {
      "Effect":"Deny",
      "Action":"*",
      "Resource":"*",
      "Condition":{
         "NumericLessThan":{
            "ec2:RoleDelivery":"2.0"
         }
      }
   },
   {
      "Effect":"Deny",
      "Action":"ec2:ModifyInstanceMetadataOptions",
      "Resource":"*"
   }
]

以下策略限制所有用户在没有 IMDSv2 的情况下启动 EC2 实例，但允许特定 IAM 身份修改实例元数据选项。

[
  {
    "Effect": "Deny",
    "Action": "ec2:RunInstances",
    "Resource": "arn:aws:ec2:*:*:instance/*",
    "Condition": {
      "StringNotEquals": {
        "ec2:MetadataHttpTokens": "required"
      }
    }
  },
  {
    "Effect": "Deny",
    "Action": "ec2:RunInstances",
    "Resource": "arn:aws:ec2:*:*:instance/*",
    "Condition": {
      "NumericGreaterThan": {
        "ec2:MetadataHttpPutResponseHopLimit": "3"
      }
    }
  },
  {
    "Effect": "Deny",
    "Action": "*",
    "Resource": "*",
    "Condition": {
      "NumericLessThan": {
        "ec2:RoleDelivery": "2.0"
      }
    }
  },
  {
    "Effect": "Deny",
    "Action": "ec2:ModifyInstanceMetadataOptions",
    "Resource": "*",
    "Condition": {
      "StringNotLike": {
        "aws:PrincipalARN": [
          "arn:aws:iam::{ACCOUNT_ID}:{RESOURCE_TYPE}/{RESOURCE_NAME}"
        ]
      }
    }
  }
]

防止禁用默认 Amazon EBS 加密

以下策略限制所有用户禁用默认 Amazon EBS 加密。

{
  "Effect": "Deny",
  "Action": [
    "ec2:DisableEbsEncryptionByDefault"
  ],
  "Resource": "*"
}
