What is AWS Config?
AWS Config is a service that allows you to evaluate, audit and assess your AWS resources. Through AWS Config, you can record and monitor your resource configuration. It also enables you to automate the evaluation of recorded configuration against the desired configuration. Therefore, you can review the changes occurring in the configuration of your resources. Moreover, Amazon Config gives you a deep insight into resource configuration history and determine your overall compliance against the configurations that you have specified.
AWS config monitoring and alarms is a security best practice
AWS Configure services are often used by developers or operations teams to avoid misconfigurations at AWS resource/service level and close security gaps. Once you enable the AWS Config, it starts detecting your existing cloud resources, records of their current configurations and changes that have occurred in these resources. Data recorded by AWS Config can be extremely useful for security audit, operational troubleshooting and compliance use cases as well. It can determine how an AWS resource was set up at a certain point of time and what relationship it had with other services and resources. You need to be aware of all the configuration changes made in the AWS Config. Therefore, it is essential to monitor any configuration changes made at the Config service level to keep your AWS cloud environment safe.

|Ok: Following trail has CW logs groups configured with metric filter, alarm, SNS topic with at least one subscriber.|
|Warning: No SNS topic exists OR No subscribers to the list Of SNS topics this alarm OR No alarm exists. Hence no associated SNS topic OR desired filter pattern doesn’t exist on any of the alarm existing in this region OR Metric filter doesn’t exist. Thus no associated alarm and SNS topic.|
|Critical: Delivery to CloudWatch logs not configured|
Description of further columns are as follows:
Account Id: Shows the respective account ID of the user’s account.
Account Name: Shows the account name corresponding to the user’s account.
Region: This column shows the region of your instance where it has been used.
Identifier: Shows you the service with its trial name.
Log Group Name: It represents the name of the group which has permission to use the service.
Metric Filter Name: Shows you the name that you have given to the metric filter

|Account Id||Applying account Id filter will display all the public snapshots for the selected account Id.|
|Region||Applying the region filter will display all the public snapshots corresponding to the selected region.|
|Severity||Applying severity filter will display public snapshots according to the selected severity type i.e. selecting critical will display all instances with critical severity. Same will be the case for Warning and Ok severity types.|
|Resource Tags||Applying resource tags filter will display those public snapshots which have been assigned the selected resource tag. For e.g., If a user has tagged some public snapshots by a resource tag named environment, then selecting an environment from the resource tags filter will display all those snapshots.|
|Resource Tags Value||Applying resource tags value filter will display data which will have the selected resource tag value. For e.g. – Let’s say a user has tagged some resource by a tag named environment and has a value say production (environment: production). Hence, the user can view data of all the resources which are tagged as “environment:production”. The user can use the tag value filter only when a tag name has been provided.|
|Compliance||Applying Compliance filter, you can further refine your security and health checks.|
