Introduction

As part of the AWS account preparation required before onboarding cloud accounts into the platform, you will need to create least privilege policies— individual policies that must be attached to your cross-account role that allow the platform to access the AWS data it needs in order to create its reports.

Least Privilege Polices by Product (Read-Only)

Each least privilege policy provides the necessary permissions to enable core functions in the platform. The policies for enabling Read-Only access to the platform are listed below organized by product and platform capability:

Pre-configured automation templates for allowing access
You can use the S3 URLs provided based on the type of access you wish to provide for the platform.

S3 URL with Template for Read-Only Access:

FinOps: https://corestack-cfn.s3.amazonaws.com/AWS_Onboarding_FinopsBundle_Template.json

SecOps: https://corestack-cfn.s3.amazonaws.com/AWS_Onboarding_SecopsBundle_Template.json

Capability	Description	Least Privilege Permissions
Cost Visibility and Usage	Enabling this permission helps CoreStack retrieve cost data from AWS and display it in the Cost Posture section(s), which provides visibility into costs across all your cloud accounts.	`s3:GetObject` `arn:aws:s3:::[YOUR COST AND USAGE REPORT BUCKET]/* (For Master Account)`
Support and RI	Enabling these permissions allows access to pricing model information that can help users increase cost savings for their AWS resource usage, compute Savings Plans that can provide lower prices on EC2 instance usage, and support services that help customers use AWS products and features.	`ce:DescribeNotificationSubscription,` `ce:GetReservationPurchaseRecommendation,` `ce:GetReservationUtilization,` `support:DescribeServices,` `support:DescribeSupportLevel,` `support:DescribeTrustedAdvisorCheckResult`
Cost Budget and Billing	These permissions allow cloud-native budgets for AWS to be displayed in the CoreStack portal.	`budgets:ViewBudget,` `budgets:DescribeBudgetActionHistories,` `budgets:DescribeBudgetActionsForAccount`
Cost Optimization	These permissions allow the monitoring of resource utilization data and the reclaiming of native recommendations, which in turn can help users achieve potential cost savings through FinOps policies.	`compute-optimizer:DescribeRecommendationExportJobs,` `compute-optimizer:GetAutoScalingGroupRecommendations,` `compute-optimizer:GetEBSVolumeRecommendations,` `compute-optimizer:GetEC2InstanceRecommendations,` `compute-optimizer:GetEC2RecommendationProjectedMetrics,` `compute-optimizer:GetECSServiceRecommendationProjectedMetrics,` `compute-optimizer:GetECSServiceRecommendations,` `compute-optimizer:GetEffectiveRecommendationPreferences,` `compute-optimizer:GetEnrollmentStatus,` `compute-optimizer:GetLambdaFunctionRecommendations,` `compute-optimizer:GetRecommendationPreferences,` `compute-optimizer:GetRecommendationSummaries`
Resource Inventory & Cost Optimizations ( CoreStack Policies)	These permissions allow CoreStack to pull resources from AWS in order to provide cost recommendations through FinOps policies.	`access-analyzer:List,` `acm:DescribeCertificate,` `acm:GetCertificate,` `acm:ListCertificates,` `acm:ListTagsForCertificate,` `apigateway:GET,` `application-autoscaling:DescribeScheduledActions,` `autoscaling:Describe,` `batch:Describe,` `clouddirectory:DescribeDirectories,` `clouddirectory:GetDirectory,` `clouddirectory:ListDirectories,` `cloudformation:DescribeStacks,` `cloudformation:GetStackPolicy,` `cloudformation:GetTemplate,` `cloudformation:ListStackResources,` `cloudformation:ListStacks,` `cloudfront:Get,` `cloudfront:List,` `cloudhsm:Describe,` `cloudhsm:List,` `cloudtrail:DescribeTrails,` `cloudtrail:Get,` `cloudtrail:ListTrails,` `cloudwatch:GetDashboard,` `cloudwatch:GetMetricStatistics,` `cloudwatch:ListDashboards,` `cloudwatch:ListMetrics,` `cloudwatch:GetMetricData,` `cloudwatch:Describe,` `codeartifact:DescribeDomain,` `codepipeline:List,` `cognito-identity:Describe,` `cognito-identity:Get,` `cognito-user:List,` `cognito-user:Describe,` `datapipeline:DescribePipelines,` `datapipeline:GetPipelineDefinition,` `datapipeline:ListPipelines,` `directconnect:DescribeConnections,` `directconnect:DescribeLocations,` `directconnect:DescribeVirtualGateways,` `directconnect:DescribeVirtualInterfaces,` `dms:Describe,` `dynamodb:Describe,` `dynamodb:ListTables,` `dynamodb:ListTagsOfResource,` `ec2:Describe,` `ecr:BatchGetImage,` `ecr:BatchImportUpstreamImage,` `ecr:DescribeRepositories,` `ecr:GetLifecyclePolicy,` `ecr:GetLifecyclePolicyPreview,` `ecr-public:GetRepositoryCatalogData,` `ecs:Describe,` `ecs:List,` `eks:Describe,` `eks:List,` `elasticache:Describe,` `elasticbeanstalk:Describe,` `elasticfilesystem:Describe,` `elasticloadbalancing:Describe,` `elasticmapreduce:Describe,` `elasticmapreduce:List,` `es:Describe,` `es:ListDomainNames,` `glacier:Describe,` `glacier:List,` `glue:List,` `glue:Get,` `guardduty:GetDetector,` `guardduty:ListDetectors,` `iam:GetGroup,` `iam:GetGroupPolicy,` `iam:GetPolicy,` `iam:GetRole,` `iam:GetRolePolicy,` `iam:GetUser,` `iam:GetUserPolicy,` `iam:List,` `iam:SimulatePrincipalPolicy,` `inspector:Describe,` `inspector:List,` `iot:DescribeThing,` `iot:ListThings,` `kafka:Describe,` `kafka:List,` `kinesis:DescribeStream,` `kinesis:GetShardIterator,` `kinesis:ListStreams,` `kinesis:ListTagsForStream,` `kms:Describe,` `kms:Get,` `kms:List,` `lambda:Get,` `lambda:List,` `lightsail:Get,` `logs:DescribeLogGroups,` `logs:DescribeLogStreams,` `logs:GetLogEvents,` `mgh:DescribeApplicationState,` `mgh:ListApplicationStates,` `mq:DescribeBroker,` `mq:ListBrokers,` `opsworks:DescribeStacks,` `opsworks:DescribeStackSummary,` `opsworks:DescribeUserProfiles,` `organizations:Describe,` `organizations:List,` `qldb:DescribeLedger,` `quicksight:Describe,` `quicksight:List,` `rds:Describe,` `rds:List,` `redshift:Describe,` `route53:GetTrafficPolicy,` `route53:GetTrafficPolicyInstance,` `route53:List,` `S3:GetAccountPublicAccessBlock,` `s3:GetBucketACL,` `s3:GetBucketLocation,` `s3:GetBucketPolicy,` `s3:GetBucketPublicAccessBlock,` `s3:GetBucketTagging,` `s3:GetLifecycleConfiguration,` `s3:GetNotificationConfiguration,` `s3:ListAllMyBuckets,` `s3:ListBucket,` `sdb:DomainMetadata,` `sdb:ListDomains,` `secretsmanager:List,` `secretsmanager:Describe,` `servicecatalog:Describe,` `servicecatalog:List,` `sheild:DescribeProtection,` `sheild:ListProtections,` `sns:GetSnsTopic,` `sns:GetSubscriptionAttributes,` `sns:GetTopicAttributes,` `sns:ListSubscriptionsByTopic,` `sns:ListTopics,` `sqs:GetQueueAttributes,` `sqs:ListQueues,` `ssm:Describe,` `ssm:Get,` `ssm:List,` `storagegateway:Describe,` `storagegateway:List,` `swf:List,` `waf:Get,` `waf:List,` `waf-regional:Get,` `waf-regional:List,` `wafv2:Get,` `wafv2:List,` `workmail:Describe,` `workmail:List,` `workspaces:Describe*`
