2. Understanding AWS Config

AWS Config is a service provided by AWS that allows customers to assess, audit, and evaluate the configurations of their AWS resources. It continuously monitors and records the configurations of AWS resources and the relationships between each resource, creating an inventory of resource configurations and capturing their changes over time. AWS Config offers benefits such as:

  • Configuration history: Enables tracking and auditing of changes made to AWS resource configurations.
  • Compliance analysis: Assists in evaluating resource configurations against industry standards and internal policies.
  • Resource relationships: Provides insights into the dependency and relationship between different AWS resources.
  • Resource change notifications: Offers real-time notifications for changes made to AWS resources.
  • Troubleshooting and debugging: Facilitates root cause analysis for resource-related problems.

AWS Config achieves these benefits by utilizing managed rules, which are predefined or user-defined rules used to evaluate the compliance state of AWS resources. Managed rules play a vital role in ensuring resource configurations comply with AWS best practices and internal policies. These rules can be customized to match specific requirements and automatically evaluate the compliance of resources.

3. The Synergy of AWS Trusted Advisor and AWS Config
