Using Console

Using CLI

Create Metric Filter:

aws logs put-metric-filter \
  --log-group-name "YOUR_LOG_GROUP_NAME" \
  --filter-name "IAMPolicyChangesFilter" \
  --filter-pattern '{ $.eventSource = "iam.amazonaws.com" && $.eventName = "AttachRolePolicy" }' \
  --metric-transformations "metricName=IAMPolicyChangesEventCount,metricNamespace=CloudTrailMetrics,metricValue=1"

Replace "YOUR_LOG_GROUP_NAME" with the name of your CloudTrail log group.

Create CloudWatch Alarm (optional): Use the put-metric-alarm command to create an alarm based on the metric you created.

Using Python

import boto3

cloudwatch_logs = boto3.client('logs')
cloudwatch = boto3.client('cloudwatch')

# Create Metric Filter
response = cloudwatch_logs.put_metric_filter(
    logGroupName='YOUR_LOG_GROUP_NAME',
    filterName='IAMPolicyChangesFilter',
    filterPattern='{ $.eventSource = "iam.amazonaws.com" && $.eventName = "AttachRolePolicy" }',
    metricTransformations=[
        {
            'metricName': 'IAMPolicyChangesEventCount',
            'metricNamespace': 'CloudTrailMetrics',
            'metricValue': 1
        }
    ]
)

# Create CloudWatch Alarm (optional)
# You can use cloudwatch.put_metric_alarm() to create an alarm based on the metric

Replace "YOUR_LOG_GROUP_NAME" with the name of your CloudTrail log group.These steps should help you set up the IAMPolicyChangesEventCount metric in CloudWatch using the AWS Console, AWS CLI, or Python script. Remember to adjust the configuration according to your specific use case and environment.
