Automating Identity and Access Management (IAM) tasks can greatly improve efficiency and security in an organization. Below, I’ll provide a Python script example for automating some common IAM tasks using the AWS Identity and Access Management (IAM) service. This script assumes you have the AWS SDK (Boto3) installed and configured with valid credentials.

Before running the script, make sure to:

  1. Install Boto3: You can install Boto3 using pip.
pip install boto3
  1. Configure AWS Credentials: Configure AWS credentials using the aws configure command or by setting environment variables.

Now, let’s create a Python script to automate some IAM tasks. In this example, we’ll create a new IAM user, assign a policy to the user, and generate access keys for them:

import boto3

# AWS IAM client
iam = boto3.client('iam')

# IAM User Details
username = 'new_user_name'
policy_name = 'YourPolicyName'

# Step 1: Create a new IAM user
try:
    response = iam.create_user(UserName=username)
    print(f"IAM User '{username}' created successfully.")
except iam.exceptions.EntityAlreadyExistsException:
    print(f"IAM User '{username}' already exists.")
except Exception as e:
    print(f"Error creating IAM user: {e}")

# Step 2: Attach a policy to the IAM user
try:
    response = iam.attach_user_policy(
        UserName=username,
        PolicyArn='arn:aws:iam::aws:policy/' + policy_name
    )
    print(f"Policy '{policy_name}' attached to '{username}' successfully.")
except iam.exceptions.NoSuchEntityException:
    print(f"Policy '{policy_name}' not found.")
except Exception as e:
    print(f"Error attaching policy to IAM user: {e}")

# Step 3: Generate Access Keys for the IAM user
try:
    response = iam.create_access_key(UserName=username)
    access_key = response['AccessKey']
    print(f"Access Key ID: {access_key['AccessKeyId']}")
    print(f"Secret Access Key: {access_key['SecretAccessKey']}")
except Exception as e:
    print(f"Error creating access keys: {e}")

Replace 'new_user_name' and 'YourPolicyName' with the desired username and policy name. Ensure that you have the appropriate permissions to perform these IAM actions.

This script creates a new IAM user, attaches a policy to the user, and generates access keys. Please be cautious when automating IAM tasks, as they can have significant security implications. Ensure that your IAM policies and configurations align with your organization’s security best practices.
