AWS IAM Self Manage Policy

Here’s the permission needed for an AWS user to manage their own IAM account. The policy allows them to view their own account information, change their own passwords, rotate access keys and certificates, and manage their own git credentials.

AWS Display IAM Certificates

SSL certificates were uploaded to IAM prior to Certificate Manager. Unfortunately, the certificates are not visible from the IAM console. There’s no way to view when a certificate is expiring. So, here’s how to display IAM certificates from the AWS CLI.

SSL Certificates Explained

If you’re confused about the different formats and files that the Certificate Manager will accept in AWS, this site explains it fairly well. The Certificate Manager contains 3 fields during the import process. Certificate body, Certificate private key, and Certificate chain.

  • Server certificate > Intermediate certificate > Root certificate
  • Private RSA Key
  • Chain consists of Root and Intermediate
  • Cloud
  • Linux
  • Git
