Deploy all Password policy using terragrunt code and also with manual step-by-step procedure.

Introduction:-

The password policy in #AWS Identity and Access Management (IAM) is a set of rules that define the requirements for creating and managing user passwords. It helps ensure that passwords are secure and difficult to guess, reducing the risk of unauthorized access to AWS resources. The ##IAM password policy includes settings for password length, complexity, age, and reuse, and can be configured using the #AWS Management Console, CLI, or #API. A strong password policy is an important aspect of AWS security best practices.

Issue 1: Ensure IAM password policy requires at least one uppercase letter

This AWS control checks whether the #Amazon EC2 instances in your account are managed by AWS Systems Manager.

Issue 2: Ensure IAM password policy requires at least one lowercase letter

Password policies are, in part, used to enforce password complexity requirements. IAM password policies can be used to ensure passwords are comprised of different character sets. It is recommended that the password policy require at least one lowercase letter.

Issue 3: Ensure IAM password policy requires at least one symbol

Issue 4: Ensure IAM password policy requires at least one number:

Issue 5 : Ensure IAM password policy requires minimum password length of 14 or greater

Password policies are, in part, used to enforce password complexity requirements. #IAM password policies can be used to ensure passwords are at least a given length. It is recommended that the password policy require a minimum password length 14.

General step to follow: Create one folder name it IAM,using the same folder create one file and name it terragrunt.hcl and paste the below code into that file.For module reference click on the below link

Terraform Registry
registry.terraform.io

This is an example reference.

# terragrunt.hcl
terraform {
  source = "terraform-aws-modules/iam/aws"
}
include {
  path = find_in_parent_folders()
}
inputs = {
  # Require a minimum password length of 12 characters
  minimum_password_length = 12
  # Require at least one lowercase letter, one uppercase letter, one number, and one special character in the password
  require_lowercase_characters = true
  require_uppercase_characters = true
  require_numbers = true
  require_symbols = true
  # Enforce a maximum password age of 90 days
  max_password_age = 90
  # Prevent password reuse for the last 5 passwords
  password_reuse_prevention = 5
}

After paste this code in the file. Just save and open the terminal enter the first command terragrunt init for Initializing and after Initialization, enter the second command terragrunt plan when the plan executed successfully ,enter the third command terragrunt apply after apply configuration would be done in your aws Iam console.

Follow the step to setup the password policy manually:

To modify the password policy

Open the IAM console at https://console.aws.amazon.com/iam/.
Choose Account settings.
Select Requires at least one uppercase letter and then choose Apply password policy.
Select Requires at least one lowercase letter and then choose Apply password policy.
Select Require at least one non-alphanumeric character and then choose Apply password policy.
Select Requires at least one number and then choose Apply password policy.
In the Minimum password length field, enter 14, then choose Apply password policy.

Conclusion:-

Implementing a strong password policy for #IAM users is crucial for maintaining the security of your #AWS environment. By configuring password requirements such as minimum length, complexity, age, and reuse prevention, you can reduce the risk of unauthorized access to your #AWS resources. The password policy settings can be configured using the #AWS Management Console, CLI, or API, and can also be automated using #Terraform or other infrastructure-as-code tools. A strong password policy is a fundamental component of a comprehensive AWS security strategy.
