AWS Cloudformation：负载均衡器自定义 SSL 协商策略

Question

尝试使用自定义 SSL 协商策略设置 cloudformation 模板。我得到的 cloudformation 错误是：

CREATE_FAILED AWS::ElasticLoadBalancing::LoadBalancer BackendELB SSLNegotiationPolicy 无法启用

我的cloudformation模板部分如下：

"Policies" : [
                {
                    "PolicyName": "SSLNegotiationPolicy",
                    "PolicyType": "SSLNegotiationPolicyType",
                    "Attributes": [
                        { "Name" : "Protocol-TLSv1", "Value" : "true" },
                        { "Name" : "Protocol-TLSv1.1", "Value" : "true" },
                        { "Name" : "Protocol-TLSv1.2", "Value" : "true" },
                        { "Name" : "Protocol-SSLv2", "Value" : "false" },
                        { "Name" : "Protocol-SSLv3", "Value" : "false" },
                        { "Name" : "ECDHE-RSA-AES128-GCM-SHA256", "Value" : "true" },
                        { "Name" : "ECDHE-ECDSA-AES128-SHA256", "Value" : "true" },
                        { "Name" : "ECDHE-RSA-AES128-SHA256", "Value" : "true" },
                        { "Name" : "ECDHE-ECDSA-AES128-SHA", "Value" : "true" },
                        { "Name" : "ECDHE-RSA-AES128-SHA", "Value" : "true" },
                        { "Name" : "DHE-RSA-AES128-SHA", "Value" : "true" },
                        { "Name" : "ECDHE-ECDSA-AES256-GCM-SHA384", "Value" : "true" },
                        { "Name" : "ECDHE-RSA-AES256-GCM-SHA384", "Value" : "true" },
                        { "Name" : "ECDHE-ECDSA-AES256-SHA384", "Value" : "true" },
                        { "Name" : "ECDHE-RSA-AES256-SHA384", "Value" : "true" },
                        { "Name" : "ECDHE-RSA-AES256-SHA", "Value" : "true" },
                        { "Name" : "ECDHE-ECDSA-AES256-SHA", "Value" : "true" },
                        { "Name" : "AES128-GCM-SHA256", "Value" : "true" },
                        { "Name" : "AES128-SHA256", "Value" : "true" },
                        { "Name" : "AES128-SHA", "Value" : "true" },
                        { "Name" : "AES256-GCM-SHA384", "Value" : "true" },
                        { "Name" : "AES256-SHA256", "Value" : "true" },
                        { "Name" : "AES256-SHA", "Value" : "true" },
                        { "Name" : "DHE-DSS-AES128-SHA", "Value" : "true" },
                        { "Name" : "RC4-SHA", "Value" : "false" },
                        { "Name" : "ECDHE-ECDSA-RC4-SHA", "Value" : "false" }
                    ],
                    "InstancePorts" : [ "443" ]
               } 
           ]

如果我删除 InstancePorts 部分，则 ELB 创建时不会出现错误，但新的负载均衡器不使用概述的策略。

有什么想法吗？

附带问题：是否有必要将策略的每个值都设置为 true 或 false，或者如果模板中未定义密码，它是否默认为推荐的 SSL 策略中定义的值？

我认为你在正确的轨道上。您可以通过以下方式查看现有的安全策略内容：

aws elb describe-load-balancer-policies

为了完整性，我指定了所有内容，例如以下政策：

    "Policies" : [
      {
        "PolicyName" : "My-ELBSecurityPolicy-2014-10-DisableRC4",
        "PolicyType" : "SSLNegotiationPolicyType",
        "Attributes" : [
            { "Name": "Protocol-SSLv2", "Value": "false" }, 
            { "Name": "Protocol-TLSv1", "Value": "true" }, 
            { "Name": "Protocol-SSLv3", "Value": "false" }, 
            { "Name": "Protocol-TLSv1.1", "Value": "true" }, 
            { "Name": "Protocol-TLSv1.2", "Value": "true" }, 
            { "Name": "Server-Defined-Cipher-Order", "Value": "true" }, 
            { "Name": "ECDHE-ECDSA-AES128-GCM-SHA256", "Value": "true" }, 
            { "Name": "ECDHE-RSA-AES128-GCM-SHA256", "Value": "true" }, 
            { "Name": "ECDHE-ECDSA-AES128-SHA256", "Value": "true" },

            { "Name": "EXP-KRB5-RC4-MD5", "Value": "false" }
        ]
      }
    ]

您还必须参考 ELB 规范本身中的策略：

    "Listeners" : [
      { "LoadBalancerPort" : "80",
        "InstancePort" : "80",
        "Protocol" : "HTTP" },
      { "LoadBalancerPort" : "443",
        "InstancePort" : "80",
        "Protocol" : "HTTPS",
        "SSLCertificateId" : "arn:aws:iam::111111111111:server-certificate/somedomain.com",
        "PolicyNames" : [ "My-ELBSecurityPolicy-2014-10-DisableRC4", "SomeOtherPolicy" ]
      }
    ],
