Configuration history of AWS resources
AWS Config records details of changes to your AWS resources to provide you with a configuration history. You can use the AWS Management Console, API, or CLI to obtain details of what a resource’s configuration looked like at any point in the past. AWS Config will also automatically deliver a configuration history file to the Amazon S3 bucket you specify.
Configuration history of software
AWS Config enables you to record software configuration changes within your Amazon EC2 instances and servers running on-premises, as well as servers and Virtual Machines in environments provided by other cloud providers. With AWS Config, you gain visibility into operating system (OS) configurations, system-level updates, installed applications, network configuration and more. AWS Config also provides a history of OS and system-level configuration changes alongside infrastructure configuration changes recorded for EC2 instances.
Resource relationships tracking
AWS Config discovers, maps, and tracks AWS resource relationships in your account. For example, if a new Amazon EC2 security group is associated with an Amazon EC2 instance, AWS Config records the updated configurations of both the Amazon EC2 security group and the Amazon EC2 instance.
Configurable and customizable rules
AWS Config provides you with pre-built rules for evaluating provisioning and configuring of your AWS resources as well as software within managed instances, including Amazon EC2 instances and servers running on-premises. You can customize pre-built rules to evaluate your AWS resource configurations and configuration changes, or create your own custom rules in AWS Lambda that define your internal best practices and guidelines for resource configurations. Using AWS Config, you can assess your resource configurations and resource changes for compliance against the built-in or custom rules.
Conformance packs help you manage compliance of your AWS resource configuration at scale--from policy definition to auditing and aggregated reporting--using a common framework and packaging model. Conformance packs are integrated with AWS Organizations. Using conformance packs as your compliance framework, you can package a collection of AWS Config rules and remediation actions into a single entity (known as a conformance pack) and deploy it across an entire organization. This is particularly useful if you need to quickly establish a common baseline for resource configuration policies and best practices across multiple accounts in your organization in a scalable and efficient way.
Multi-account, multi-region data aggregation
Multi-account, multi-region data aggregation is a capability in AWS Config that enables centralized auditing and governance. It gives you an enterprise-wide view of your AWS Config rule compliance status, and you can associate your AWS organization to quickly add your accounts. The aggregated dashboard in AWS Config will display the total count of non-compliant rules across your organization, the top five non-compliant rules by number of resources, and the top five AWS accounts that have the most number of non-compliant rules. You can then drill down to view details about the resources that are violating the rule, and the list of rules that are being violated by an account.
AWS Config supports extensibility by allowing you to publish the configuration of third-party resources into AWS Config using our public APIs. Examples of third- party resources include version control systems such as GitHub, Microsoft Active Directory resources or any on-premises server. AWS Config enables you to view and monitor the resource inventory and configuration history of these third-party resources using the AWS Config console and APIs, like you do for AWS resources. You can also create AWS Config rules or conformance packs to evaluate these third-party resources against best practices, internal policies, and regulatory policies.
AWS Config can provide you with a configuration snapshot - a point-in-time capture of all your resources and their configurations. Configuration snapshots are generated on demand via the AWS CLI or API and delivered to the Amazon S3 bucket you specify.
Cloud governance dashboard
AWS Config provides you a visual dashboard to help you quickly spot non-compliant resources and take appropriate action. IT Administrators, Security Experts, and Compliance Officers can see a shared view of your AWS resources compliance posture.
You can choose from numerous AWS Partner Network (APN) partners who provide solutions that integrate with AWS Config for resource discovery, change management, compliance, or security. To learn more about AWS Config APN Partners, visit here.
AWS Config integrates with AWS CloudTrail to correlate configuration changes to particular events in your account. You can use the CloudTrail logs to obtain the details of the event that invoked the change, including who made the request, at what time, and from which IP address. You can navigate to the Config timeline from the AWS CloudTrail console to view the configuration changes related to your AWS API activities. To learn more about this feature, read our documentation here.
AWS Systems Manager
AWS Config integrates with AWS Systems Manager to record configuration changes to software on your Amazon EC2 instances and servers in your on-premises environment. With this integration, you can gain visibility into operating system (OS) configurations, system-level updates, installed applications, network configuration, and more. Config also provides a history of OS and system-level configuration changes alongside infrastructure configuration changes recorded for EC2 instances. You can navigate to the Config timeline from the Systems Manager console to view the configuration changes of your managed EC2 instances.
Amazon EC2 Dedicated Host
AWS Config integrates with Amazon EC2 Dedicated Hosts to assess license compliance. Config records when instances are launched, stopped, or terminated on a Dedicated Host, and pairs this information with host and instance level information relevant to software licensing, such as Host ID, Amazon Machine Image (AMI) IDs, number of sockets and physical cores. This enables you to use Config as a data source for your license reporting. You can navigate to the Config timeline from the Amazon EC2 Dedicated Hosts console to view the configuration changes of your Amazon EC2 Dedicated Hosts.
Application Load Balancers
AWS Config integrates with Elastic Load Balancing (ELB) service to record configuration changes to Application Load Balancers. Config also includes relationships with associated EC2 security groups, VPCs, and subnets. You can use this information for security analysis and troubleshooting. For example, you can check which security groups are associated with your application load balancer at any point in time. You can navigate to the Config timeline from the ELB console to view the configuration changes of your Application Load Balancers.
You can use AWS Organizations to define the accounts to use for AWS Config’s multi-account, multi-region data aggregation capability. AWS Organizations is an account management service that enables you to consolidate multiple AWS accounts into an organization that you create and centrally manage. By providing your AWS Organizations details, you can monitor the compliance status across your organization.
