Data-plane actions (0)

By access level: none.

This policy grants no actions in this plane.

Excluded and conditional actions

No patterns are excluded by NotAction or Deny statements.

Resource scope and attachment

Resource scope across granted actions: mixed.

Can be attached: Yes, to users, groups and roles.

Why this tier

  • Grants only List and Read actions.

Guidance

Practical scope

The policy allows elasticloadbalancing:Describe* and elasticloadbalancing:Get*, ec2:DescribeInstances, ec2:DescribeClassicLinkInstances and ec2:DescribeSecurityGroups on Resource "*". It also allows arc-zonal-shift:GetManagedResource on arn:aws:elasticloadbalancing:*:*:loadbalancer/* and arc-zonal-shift:ListManagedResources and arc-zonal-shift:ListZonalShifts on "*".

Use cases

  • Let users view Elastic Load Balancing resources and the EC2 and zonal shift information related to them without changing them.

Best practices

  • AWS managed policies don't grant least privilege permissions. The IAM User Guide suggests using IAM Access Analyzer to see which permissions principals actually use, then writing a custom policy or generating one with only the required permissions.

Security considerations

  • The policy grants no write actions, but it applies to all resources and also reads EC2 instances and security groups and zonal shift information.
  • You cannot change the permissions in an AWS managed policy. If AWS updates the policy, the update affects every user, group and role it is attached to.

Assignment guidance

You can attach this policy to your users, groups and roles. The reference page also links to guidance on creating a permission set using AWS managed policies in IAM Identity Center. It fits where read only access to Elastic Load Balancing is intended.

Frequently asked questions

When should I attach ElasticLoadBalancingReadOnly?
The Elastic Load Balancing User Guide says it provides read-only access to Elastic Load Balancing and dependent services, and the reference page says you can attach it to your users, groups and roles. Attach it where viewing load balancers is the intended scope.
What does ElasticLoadBalancingReadOnly grant?
It allows elasticloadbalancing:Describe* and elasticloadbalancing:Get*, three EC2 describe actions and three arc-zonal-shift read actions.
What are the security risks of ElasticLoadBalancingReadOnly?
The policy grants no write actions, but it applies to all resources and also reads EC2 instance and security group details. AWS managed policies don't grant least privilege permissions, and you must consider the security risk of granting principals more permissions than they need. AWS updates to the policy affect every identity it is attached to.
