Fms webacl rulegroup association remediation

Using Console

Using CLI

To remediate the misconfiguration “FMS Web ACL Should Have Rule Group Association” using AWS CLI, follow these steps:

Open your terminal or command prompt.
Use the following AWS CLI command to update a rule group association with your FMS Web ACL:

aws wafv2 update-web-acl \
  --name <WEB_ACL_NAME> \
  --scope REGIONAL \
  --id <WEB_ACL_ID> \
  --lock-token <LOCK_TOKEN> \
  --rules '[
      {
        "Name":"<RULE_GROUP_NAME>",
        "Priority":<PRIORITY>,
        "Statement":{
          "RuleGroupReferenceStatement":{
            "ARN":"<RULE_GROUP_ARN>"
          }
        },
        "Action":{
          "Allow":{}
        }
      }
    ]'

Replace the following placeholders in the command:

<WEB_ACL_NAME>: The name of your FMS Web ACL.
<WEB_ACL_ID>: The ID of your FMS Web ACL.
<LOCK_TOKEN>: The lock token associated with the Web ACL.
<RULE_GROUP_NAME>: The name of the rule group you want to associate.
<PRIORITY>: The priority of the rule group in the Web ACL.
<RULE_GROUP_ARN>: The ARN of the rule group.

To retrieve the lock token, run the following command:

aws wafv2 get-web-acl --scope REGIONAL --id <WEB_ACL_ID> --name <WEB_ACL_NAME>

Execute the update command in your terminal. This will associate the specified rule group with your FMS Web ACL.
Verify that the rule group is successfully associated with the FMS Web ACL by checking the Web ACL configuration in the AWS Management Console or by running the following AWS CLI command:

aws wafv2 list-web-acls --scope REGIONAL

This command will list all the regional web ACLs in your account, including the one with the associated rule group.By following these steps, you can remediate the misconfiguration “FMS Web ACL Should Have Rule Group Association” using AWS CLI.

Using Python

To remediate the misconfiguration of FMS Web ACL not having a Rule Group Association using Python, you can follow these steps:

Install the necessary Python libraries: Ensure you have the AWS SDK for Python (Boto3) installed. You can install it using pip:

pip install boto3

Write a Python script to associate a Rule Group with the FMS Web ACL:

import boto3

# Initialize the WAFv2 client
wafv2_client = boto3.client('wafv2')

# Specify the Web ACL ID, name, and the Rule Group ARN that you want to associate
web_acl_id = 'YOUR_WEB_ACL_ID'
web_acl_name = 'YOUR_WEB_ACL_NAME'
rule_group_arn = 'YOUR_RULE_GROUP_ARN'
priority = 1

# Retrieve the current lock token
response = wafv2_client.get_web_acl(
    Name=web_acl_name,
    Scope='REGIONAL',
    Id=web_acl_id
)

lock_token = response['LockToken']

# Update the Web ACL to associate the Rule Group
update_response = wafv2_client.update_web_acl(
    Name=web_acl_name,
    Scope='REGIONAL',
    Id=web_acl_id,
    LockToken=lock_token,
    Rules=[
        {
            'Name': 'RuleGroupAssociation',
            'Priority': priority,
            'Statement': {
                'RuleGroupReferenceStatement': {
                    'ARN': rule_group_arn
                }
            },
            'Action': {
                'Allow': {}
            }
        }
    ]
)

print("Rule Group associated successfully with the FMS Web ACL")

Replace 'YOUR_WEB_ACL_ID', 'YOUR_WEB_ACL_NAME', and 'YOUR_RULE_GROUP_ARN' with the actual Web ACL ID, name, and Rule Group ARN you want to associate.
Run the Python script: Save the script in a file (e.g., associate_rule_group.py) and run it using Python:

python associate_rule_group.py
