IAM Best Practices

Vielen Dank

Bertram Dorn

Root Accounts Do Not Need Access Keys

Root Accounts Do Normally Not Log In

Best PracticesLock away your AWS account access keys

Create individual IAM users

Use groups to assign permissions to IAM users

Grant least privilege

Configure a strong password policy for your users

Enable MFA for privileged users

Use roles for applications that run on Amazon EC2 instances

Delegate by using roles instead of by sharing credentials

Rotate credentials regularly

Remove unnecessary credentials

Use policy conditions

Keep a history of activity

What type of events should I monitor for?

v You can monitor any specific event recorded by CloudTrail and receive notification from CloudWatch

v Monitor for security or network related events that are likely to have a high blast radius

v Popular examples based on customer feedback

1. Creation, deletion and modification of security groups and VPCs2. Changes to IAM policies or S3 bucket policies3. Failed AWS Management Console sign-in events4. API calls that resulted in authorization failures5. Launching, terminating, stopping, starting and rebooting EC2 instances

v Fully defined and pre-built CloudFormation template to get started

Receive email notifications of specific API activity
