AWS IAM User No Policies Audit: SOC2 Compliance
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
This runbook ensures that AWS IAM users don't have direct policies attached, adhering to SOC2 security guidelines. It mandates permissions be granted via group memberships or IAM roles, enhancing security and simplifying permission management. This audit is key in maintaining structured access control, crucial for SOC2 compliance in cloud environments.

Check which AWS IAM users have directly attached policies
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.This task involves identifying IAM users in an AWS environment who have individual policies attached to their accounts. This is key for security and compliance, ensuring permissions are managed through group memberships or role assumptions, rather than direct attachments, for better access control and security practices.

Attach an AWS IAM User to a Group
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.This task manages user permissions in AWS by confirming the existence of both IAM users and groups, ensuring users aren't already in the target group, and then adding them if necessary. This process streamlines user access management and maintains organized, best-practice-based user-group associations in AWS IAM.

Attach AWS IAM User Policy to Assume a Role
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.This task assigns a policy to an IAM user, enabling them to assume a specified IAM role. This key security measure allows controlled, temporary access elevation in line with the principle of least privilege. It's essential for secure and efficient permission management in AWS. Note:- This will directly attach a policy to the AWS IAM User.
