Prepare for an Orchestrated AWS Deployment

Prepare to install the AWS plugin and configure it to set up your security deployment in the AWS public cloud.
Complete the following tasks on AWS and Panorama before you orchestrate a VM-Series firewall on AWS.
  • AWS
    • Create an AWS user or instance profile for a specific AWS account with programmatic access and necessary permissions to allow the plugin to create resources on security VPC.
      For Security Account
      —An AWS Account with an user or instance profile who has the necessary permissions to launch AWS resources such as VPCs, VM instances, AWS load balancer, NAT gateways, and endpoints. The plugin needs the existing user or instance profile to have the following set of permissions to declare the IAM role valid. The CFT hyperlink under
      Security Account
      creates a policy with the following permissions.
      "Statement":[ { "Effect": "Allow", "Action": "ec2:*", "Resource": "*" }, { "Effect": "Allow", "Action": "elasticloadbalancing:*", "Resource": "*" }, { "Effect": "Allow", "Action": "cloudwatch:*", "Resource": "*" }, { "Effect": "Allow", "Action": "autoscaling:*", "Resource": "*" }, { "Effect": "Allow", "Action": "sts:assumerole", "Resource": "*" }, { "Effect": "Allow", "Action": "cloudformation:*", "Resource": "*" }, { "Effect": "Allow", "Action": [ "iam:Get*", "iam:List*", "iam:PassRole" ], "Resource": "*" }, { "Effect": "Allow", "Action": "ram:*", "Resource": "*" } ] },

      The following granulized permissions accommodate your requirements and security permissions. These permissions provide a detailed explanation for the API calls made from the plugin. The permissions are granulized to accommodate every action that will be called from the CFT and plugin back-end code for both Security VPC and cross-account Application VPC.
      The following permissions are not implemented in the AWS plugin for Panorama version 3.0.1 because the detailed permissions list exceed the AWS policy size limitation.For inline policies, you can add as many policies as you want for a user, role, or group, but the total aggregate policy size per entity cannot exceed these limits—user policy size cannot exceed 2048 characters, role policy size cannot exceed 10240 characters, and groups policy size cannot exceed 5120 characters. Due to these limitations and back-end validation time, you must use the above mentioned permissions.
      { "Version": "2012-10-17", "Statement": [ { "Sid": "VisualEditor0", "Effect": "Allow", "Action": [ "ec2:AuthorizeSecurityGroupIngress", "cloudwatch:PutMetricData", "ec2:Describe*", "cloudwatch:DeleteAlarms", "autoscaling:DescribePolicies", "ec2:DeleteVpcEndpoints", "ec2:AttachInternetGateway", "ec2:AcceptTransitGatewayVpcAttachment", "autoscaling:ExecutePolicy", "ec2:DeleteRouteTable", "sts:GetSessionToken", "cloudformation:DescribeStackEvents", "ec2:RevokeSecurityGroupEgress", "ec2:CreateRoute", "ec2:CreateInternetGateway", "cloudformation:UpdateStack", "ec2:DeleteInternetGateway", "iam:ListRolePolicies", "autoscaling:TerminateInstanceInAutoScalingGroup", "iam:ListPolicies", "ec2:DisassociateTransitGatewayRouteTable", "iam:GetRole", "iam:GetPolicy", "ec2:CreateTags", "elasticloadbalancing:CreateTargetGroup", "ec2:RunInstances", "ec2:DisassociateRouteTable", "ec2:CreateVpcEndpointServiceConfiguration", "ec2:CreateTransitGatewayRoute", "ec2:CreateTransitGatewayVpcAttachment", "elasticloadbalancing:DescribeAccountLimits", "elasticloadbalancing:AddTags", "cloudformation:DeleteStack", "cloudwatch:DescribeAlarms", "ec2:DeleteNatGateway", "ram:AssociateResourceShare", "autoscaling:DeleteAutoScalingGroup", "ec2:CreateSubnet", "elasticloadbalancing:ModifyLoadBalancerAttributes", "iam:GetRolePolicy", "ec2:ModifyVpcEndpoint", "ec2:DisassociateAddress", "autoscaling:DescribeAutoScalingInstances", "ec2:ModifyVpcEndpointServicePermissions", "ec2:CreateNatGateway", "ec2:CreateVpc", "ec2:ModifySubnetAttribute", "iam:PassRole", "autoscaling:DescribeScalingActivities", "sts:DecodeAuthorizationMessage", "autoscaling:DescribeLoadBalancerTargetGroups", "iam:ListAttachedGroupPolicies", "ec2:DeleteLaunchTemplateVersions", "sts:GetServiceBearerToken", "iam:ListAccessKeys", "ram:DisassociateResourceShare", "ec2:ReleaseAddress", "ec2:DeleteLaunchTemplate", "elasticloadbalancing:CreateLoadBalancer", "ec2:AcceptVpcEndpointConnections", "iam:ListGroupPolicies", "iam:ListRoles", "elasticloadbalancing:DeleteTargetGroup", "ram:AssociateResourceSharePermission", "ec2:CreateLaunchTemplate", "elasticloadbalancing:DescribeTargetGroups", "elasticloadbalancing:DeleteListener", "ram:UpdateResourceShare", "iam:GetPolicyVersion", "ec2:DeleteSubnet", "ec2:ModifyVpcEndpointServiceConfiguration", "ec2:CreateTransitGatewayRouteTable", "ec2:ModifyTransitGateway", "cloudformation:DescribeStackResource", "ec2:AssociateRouteTable", "elasticloadbalancing:DeleteLoadBalancer", "elasticloadbalancing:DescribeLoadBalancers", "logs:CreateLogStream", "ec2:GetLaunchTemplateData", "ec2:DeleteTransitGatewayVpcAttachment", "autoscaling:DescribeAutoScalingGroups", "iam:ListAttachedRolePolicies", "logs:GetLogEvents", "autoscaling:UpdateAutoScalingGroup", "ec2:AssociateTransitGatewayRouteTable", "elasticloadbalancing:ModifyTargetGroupAttributes", "autoscaling:SetDesiredCapacity", "cloudformation:DescribeStackResources", "ec2:CreateRouteTable", "ec2:DetachInternetGateway", "cloudformation:DescribeStacks", "ec2:DeleteTransitGatewayRouteTable", "sts:AssumeRole", "ec2:DeleteTransitGatewayRoute", "iam:GetUserPolicy", "iam:ListGroupsForUser", "ec2:DeleteVpc", "iam:GetGroupPolicy", "ec2:AssociateAddress", "autoscaling:CreateAutoScalingGroup", "ram:AcceptResourceShareInvitation", "ec2:DeleteTags", "logs:DescribeLogStreams", "ec2:DeleteVpcEndpointServiceConfigurations", "autoscaling:DeletePolicy", "elasticloadbalancing:RemoveTags", "elasticloadbalancing:CreateListener", "elasticloadbalancing:DescribeListeners", "autoscaling:PutScalingPolicy", "ec2:CreateSecurityGroup", "iam:ListAttachedUserPolicies", "ec2:ModifyVpcAttribute", "ec2:ModifyInstanceAttribute", "ec2:GetTransitGatewayRouteTableAssociations", "ram:DeleteResourceShare", "ec2:AuthorizeSecurityGroupEgress", "ec2:ModifyTransitGatewayVpcAttachment", "iam:GetInstanceProfile", "ram:DisassociateResourceSharePermission", "elasticloadbalancing:DescribeTags", "ec2:DeleteRoute", "iam:ListUserPolicies", "logs:PutLogEvents", "ec2:AllocateAddress", "ec2:CreateLaunchTemplateVersion", "cloudwatch:PutMetricAlarm", "cloudformation:CreateStack", "ec2:CreateVpcEndpoint", "ec2:DeleteSecurityGroup", "ec2:StartVpcEndpointServicePrivateDnsVerification", "ec2:ModifyLaunchTemplate", "iam:ListUsers", "ram:CreateResourceShare" ], "Resource": "*" } ] }

      For Application Account
      —An AWS account other than the Security account that hosts either TGW or the applications that needs to be protected. Within this account you must create a RoleARN with the following permissions.
      { "Version": "2012-10-17", "Statement": [ { "Action": [ "ec2:Describe*", "ec2:DisassociateTransitGatewayRouteTable", "ec2:CreateTransitGatewayRoute", "ec2:CreateTransitGatewayRouteTable", "ec2:AssociateTransitGatewayRouteTable", "ec2:DeleteTransitGatewayRouteTable", "ec2:DeleteTransitGatewayRoute", "ec2:GetTransitGatewayRouteTableAssociations" ], "Resource": "*", "Effect": "Allow" }, { "Action": [ "iam:Get*", "iam:List*" ], "Resource": "*", "Effect": "Allow" } ] }

    • Dedicated CIDR block
      —A CIDR block reserved for the Security VPC. The plugin manages this CIDR block, using it to launch firewalls, load balancers, and other deployment resources for the Security VPC.
    • AWS transit gateway
      —Create a TGW and ensure that the selected AWS user has permission to configure the TGW resources.
  • Panorama
    • Panorama Plugin for AWS
      —Version 3.0.1 or later.
    • VM-Series Plugin
      —Version 2.0.6 or later.
    • PanOS
      —Version 10.0.5 or later.
    • Create a valid license API key configured on Panorama for delicensing the firewalls.
    • Create an IAM role on the plugin under
      Panorama
      Plugins
      AWS
      Setup
      IAM Roles
      . This configuration needs the Access Key and Secret Key associated with the user you created in your AWS account.

Configure IAM Roles for AWS Plugin in Panorama

With the AWS plugin 3.0.1 or later, you can use IAM roles to enable Panorama to authenticate and retrieve metadata on the resources deployed within your AWS account(s). When your Panorama is not deployed on AWS, you have two options. You can either provide the long-term IAM credentials for the AWS accounts, or set up an Assume Role on AWS to allow access to the defined AWS resources within the same AWS account or cross-accounts. An Assume Role is recommended as the more secure option.
  1. To validate the AWS user credentials created for Security VPC, go to
    Panorama
    Plugins
    AWS
    Setup
    IAM Roles
    .
  2. Click
    Add
    and enter the following details under
    Security Account Detail
    .
    • Enter a name for the IAM role and an optional description.
    • Enter the AWS access key and secret key to validate permissions. Re-enter the secret key to confirm the secret access key.
    • Select an account type—
      Instance Profile
      or
      AWS Account Credentials
      . If your Panorama is deployed on AWS, you can choose to either attach an instance profile with the correct permissions to your Panorama or add the credentials associated with the IAM role on Panorama. If your Panorama is not deployed on AWS, you must enter the credentials for the IAM role locally on Panorama.
  3. Under
    Application Account Details
    , search and select the needed RoleARNs to provide valid permissions to the Security account to access the resources in the Application VPC.
    The status of validity of monitoring and deployment is color coded for ease of identification.
    • Valid (Green)—Indicates that the secret key and access key are valid. Also, all RoleARNs entered for application account access have valid permissions to do necessary action.
    • Partially valid (Orange)—Indicates that the secret key and access key are valid but one or more RoleARNs entered for application account access do not have valid permissions to do necessary action. Click the status hyperlink to open the IAM and see which specific RoleARNs do not comply.
    • Invalid (Red)—Indicates that the secret key and access key entered are either invalid or do not have permissions to do the necessary action.
    • Commit Required (Gray)—Indicates that a commit is required for the role.
    • Validating (Gray)—Indicates that the plugin is trying to connect to AWS to check the necessary requirements. If this status continues for more than a few seconds, verify if the connection to AWS is established.
    Only the IAM roles with green or orange status are allowed for further deployment configuration.
