Description​

AWS access from within AWS instances can be done by either encoding AWS keys into AWS API calls or by assigning the instance to a role that has an appropriate permissions policy for the required access. "AWS Access" means accessing AWS APIs to access AWS resources or manage AWS account resources.

Rationale​

AWS IAM roles reduce the risks associated with sharing and rotating credentials that can be used outside of AWS itself. If credentials are compromised, they can be used from outside of the AWS account they give access to. In contrast, in order to leverage role permissions an attacker would need to gain and maintain access to a specific instance to use the privileges associated with it.

Additionally, if credentials are encoded into compiled applications or other hard-to-change mechanisms, they are even less likely to be properly rotated due to service disruption risks. Over time, credentials that cannot be rotated are more likely to be known by an increasing number of individuals who no longer work for the organization.

From Console​

  1. Sign in to the AWS Management Console and navigate to EC2 dashboard at https://console.aws.amazon.com/ec2/.
  2. In the left navigation panel, choose Instances.
  3. Select the EC2 instance you want to modify.
  4. Click Actions.
  5. Click Security.
  6. Click Modify IAM role.
  7. Click Create new IAM role if a new IAM role is required.
  8. Select the IAM role you want to attach to your instance in the IAM role dropdown.
  9. Click Update IAM role.
  10. Repeat steps 3 to 9 for each EC2 instance in your AWS account that requires an IAM role to be attached.

From Command Line​

  1. Run the describe-instances command to list all EC2 instance IDs in the selected AWS region:

    aws ec2 describe-instances --region {{region-name}} --query 'Reservations[*].Instances[*].InstanceId'

  2. Run the associate-iam-instance-profile command to attach an instance profile (which contains an IAM role) to the EC2 instance:

    aws ec2 associate-iam-instance-profile \
        --region {{region-name}} \

💼 APRA CPG 234 → 💼 1 Identity and access management controls would ideally ensure access to information assets is only granted where a valid business need exists, and only for as long as access is required. Access is typically granted to users, special purpose system accounts, and information assets such as services and other software.33no data

💼 APRA CPG 234 → 💼 45 An understanding of plausible worst case scenarios can help regulated entities identify and implement additional controls to prevent or reduce the impact of such scenarios. One example is malware that infects computers and encrypts data, both on the infected computer and any connected storage, including (corporate) networks and cloud storage. Such attacks reinforce the importance of protecting the backup environment in the event that the production environment is compromised. Common techniques to achieve this include network segmentation, highly restricted and segregated access controls and network traffic flow restrictions.3537no data
