Introduction
AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. It provides a detailed view of the configuration of AWS resources in your AWS account, including how they are related to one another and how their configurations have changed over time. This comprehensive guide will delve into AWS Config’s functionalities, best practices, and ways to leverage it for effective cloud governance and compliance.
Understanding AWS Config
This tool continuously monitors and records your AWS resource configurations, allowing you to automate the evaluation of recorded configurations against desired configurations. With this tool, you can review changes in configurations and relationships between AWS resources, dive into detailed resource configuration histories, and determine your overall compliance against the configurations specified in your internal guidelines.
Key Features of AWS Config
– Configuration Recording: Continuously record the configurations of your AWS resources.
– Configuration Compliance: Determine compliance of your resources with AWS Config Rules.
– Change Management: Track changes to the configuration of AWS resources over time.
Setting Up AWS Config
1. Enable AWS Config: Start by enabling this tool in your AWS account.
2. Select Resources to Record: Choose the types of resources you want this tool to record.
3. Create Config Rules: Define rules based on your organization’s compliance requirements.
Example of enabling this tool with AWS CLI:
aws configservice put-configuration-recorder --configuration-recorder name=default,roleARN=arn:aws:iam::123456789012:role/myConfigRole,recordingGroup={allSupported=true,includeGlobalResourceTypes=true}
AWS Config Rules
Config Rules are used to evaluate the configuration of your AWS resources. You can create custom rules or use pre-built rules by AWS.
Example of setting up a config rule to check whether encryption is enabled on S3 buckets:
aws configservice put-config-rule --config-rule file://config-rule.json
Where `config-rule.json` contains the rule definition.

1. Comprehensive Coverage: Ensure this tool covers all relevant AWS resources and regions.
2. Regular Audits: Regularly audit and review AWS Config data and compliance statuses.
3. Automation: Automate responses to compliance changes using AWS Lambda functions.
Integrating with Other AWS Services
It integrates with services like AWS CloudTrail for audit trails, AWS Service Catalog for managing catalogs of IT services, and AWS Systems Manager for resource data aggregation.
Advanced Configurations
– Aggregation of Data: Aggregate configuration and compliance data across multiple AWS accounts for centralized governance.
– Tagging: Use tags for easier management and categorization of AWS resources within this tool.
Use Cases for AWS Config
– Compliance Auditing: Helps in auditing compliance with internal policies and external regulations.
– Change Tracking: Track changes and review configurations of AWS resources.
– Security Analysis: Analyze configurations to identify potential security weaknesses.
Cost Management
While this is a powerful tool, it’s essential to manage its costs, especially when monitoring a large number of resources across multiple accounts.
