以下是存储分段策略和组策略(IAM策略)的示例。

组策略(IAM)

主目录模式的存储分段访问

此组策略仅允许用户访问名为Users username的分段中的对象。

"Statement": [
    {
      "Sid": "AllowListBucketOfASpecificUserPrefix",
      "Effect": "Allow",
      "Action": "s3:ListBucket",
      "Resource": "arn:aws:s3:::home",
      "Condition": {
        "StringLike": {
          "s3:prefix": "${aws:username}/*"
        }
      }
    },
    {
      "Sid": "AllowUserSpecificActionsOnlyInTheSpecificUserPrefix",
      "Effect": "Allow",
      "Action": "s3:*Object",
      "Resource": "arn:aws:s3:::home/?/?/${aws:username}/*"
    }

  ]
}

拒绝创建对象锁定分段

此组策略将限制用户创建在存储分段上启用了对象锁定的存储分段。

备注

此策略不会在StorageGRID UI中强制实施、而是仅通过S3 API强制实施。

 
{
    "Statement": [
        {
            "Action": "s3:*",
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::*"
        },
        {
            "Action": [
                "s3:PutBucketObjectLockConfiguration",
                "s3:PutBucketVersioning"
            ],
            "Effect": "Deny",
            "Resource": "arn:aws:s3:::*"
        }
    ]
}

对象锁定保留限制

此存储分段策略会将对象锁定保留期限限制为10天或更短

{
 "Version":"2012-10-17",
 "Id":"CustSetRetentionLimits",
 "Statement": [
   {
    "Sid":"CustSetRetentionPeriod",
    "Effect":"Deny",
    "Principal":"*",
    "Action": [
      "s3:PutObjectRetention"
    ],
    "Resource":"arn:aws:s3:::testlock-01/*",
    "Condition": {
      "NumericGreaterThan": {
        "s3:object-lock-remaining-retention-days":"10"
      }
    }
   }
  ]
}

按版本ID限制用户删除对象

此组策略将限制用户按版本ID删除受版本控制的对象

{
    "Statement": [
        {
            "Action": [
                "s3:DeleteObjectVersion"
            ],
            "Effect": "Deny",
            "Resource": "arn:aws:s3:::*"
        },
        {
            "Action": "s3:*",
            "Effect": "Allow",
            "Resource": "arn:aws:s3:::*"
        }
    ]
}

此存储分段策略将限制用户(由用户ID "56622399308951294926"标识)按版本ID删除版本控制的对象

{
  "Statement": [
    {
      "Action": [
        "s3:DeleteObjectVersion"
      ],
      "Effect": "Deny",
      "Resource": "arn:aws:s3:::verdeny/*",
      "Principal": {
        "AWS": [
          "56622399308951294926"
        ]
      }
    },
    {
      "Action": "s3:*",
      "Effect": "Allow",
      "Resource": "arn:aws:s3:::verdeny/*",
      "Principal": {
        "AWS": [
          "56622399308951294926"
        ]
      }
    }
  ]
}

将存储分段限制为具有只读访问权限的单个用户

此策略允许单个用户对某个存储分段拥有只读访问权限、并明确授予所有其他用户的访问权限。将deny语句分组在策略顶部是一种较好的做法、可以加快评估速度。

{
    "Statement": [
        {
            "Sid": "Deny non user1",
            "Effect": "Deny",
            "NotPrincipal": {
                "AWS": "urn:sgws:identity::34921514133002833665:user/user1"
            },
            "Action": [
                "s3:*"
            ],
            "Resource": [
                "urn:sgws:s3:::bucket1",
                "urn:sgws:s3:::bucket1/*"
            ]
        },
        {
            "Sid": "Allow user1 read access to bucket bucket1",
            "Effect": "Allow",
            "Principal": {
                "AWS": "urn:sgws:identity::34921514133002833665:user/user1"
            },
            "Action": [
                "s3:GetObject",
                "s3:ListBucket"
            ],
            "Resource": [
                "urn:sgws:s3:::bucket1",
                "urn:sgws:s3:::bucket1/*"
            ]
        }
    ]
}

将组限制为具有只读访问权限的单个子目录(前缀)

此策略允许组成员对分段中的子目录(前缀)具有只读访问权限。分段名称为"study"、子目录为"study01"。

{
    "Statement": [
        {
            "Sid": "AllowUserToSeeBucketListInTheConsole",
            "Action": [
                "s3:ListAllMyBuckets"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::*"
            ]
        },
        {
            "Sid": "AllowRootAndstudyListingOfBucket",
            "Action": [
                "s3:ListBucket"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3::: study"
            ],
            "Condition": {
                "StringEquals": {
                    "s3:prefix": [
                        "",
                        "study01/"
                    ],
                    "s3:delimiter": [
                        "/"
                    ]
                }
            }
        },
        {
            "Sid": "AllowListingOfstudy01",
            "Action": [
                "s3:ListBucket"
            ],
            "Effect": "Allow",
            "Resource": [
                "arn:aws:s3:::study"
            ],
            "Condition": {
                "StringLike": {
                    "s3:prefix": [
                        "study01/*"
                    ]
                }
            }
        },
        {
            "Sid": "AllowAllS3ActionsInstudy01Folder",
            "Effect": "Allow",
            "Action": [
                "s3:Getobject"
            ],
            "Resource": [
                "arn:aws:s3:::study/study01/*"
            ]
        }
    ]
}
