Determining User Access Level in Cloud Environment

A.

The correct answer is A. iam_enum_permissions.

Pacu is a penetration testing tool for assessing the security of Amazon Web Services (AWS) environments. It provides various modules that can be used to perform different types of attacks.

In this scenario, the penetration tester has logged in as a user in the cloud environment of a company and wants to determine the level of access of the existing user. The IAM (Identity and Access Management) service in AWS is responsible for controlling access to AWS resources. The iam_enum_permissions module in Pacu can be used to enumerate the permissions associated with the IAM user or role.

This module will scan the user's permissions and identify the actions they can perform on AWS resources, including EC2 instances, S3 buckets, and other services. By determining the level of access of the existing user, the tester can identify potential attack vectors and assess the security posture of the AWS environment.

The other answer choices are:

B. iam_privesc_scan: This module is used to scan for potential privilege escalation opportunities in AWS environments. It does not provide information about the level of access of an existing user.

C. iam_backdoor_assume_role: This module is used to create backdoor roles in AWS environments. It does not provide information about the level of access of an existing user.

D. iam_bruteforce_permissions: This module is used to brute-force IAM permissions in AWS environments. It does not provide information about the level of access of an existing user.
