Trying to set up a cloudformation template with a custom SSL Negotiation policy. The cloudformation error I am getting is:
CREATE_FAILED AWS::ElasticLoadBalancing::LoadBalancer BackendELB SSLNegotiationPolicy cannot be enabled
My cloudformation template section is as follows:
"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" ]
}
]
If I remove the InstancePorts section then the ELB creates with no errors, but the new load balancer doesn't use the policy outlined.
Any ideas?
Side question: Is it necessary to set every value of your policy to either true or false or if the cipher is not defined in the template, does it default to the value defined in the recommended SSL policy?
I think you're on the right track. You can view the existing security policy contents with:
aws elb describe-load-balancer-policies
I specify everything for completeness, such as the policy below:
"Policies" : [

"PolicyName" : "My-ELBSecurityPolicy-2014-10-DisableRC4",

You also have to reference the policy in the ELB specification itself:
"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" ]
}
],
