Exemple de notification de changement d'élément de configuration
AWS Config utilise Amazon SNS pour envoyer des notifications aux points de terminaison d'abonnement. Ces notifications indiquent l'état de livraison des instantanés de configuration et des historiques de configuration, ainsi que chaque élément de configuration AWS Config créé lorsque les configurations des AWS ressources enregistrées changent. AWS Config envoie également des notifications indiquant si vos ressources sont conformes à vos règles. Si vous choisissez que les notifications vous soient envoyées par e-mail, vous pouvez utiliser des filtres dans votre application cliente de messagerie basés sur la ligne d'objet et le corps de message de l'e-mail.
Voici un exemple de charge utile d'une notification Amazon SNS qui est générée quand AWS Config
détecte que le volume Amazon Elastic Block Store vol-ce676ccc est attaché à l'instance dont l'ID est i-344c463d. La notification contient la modification apportée à l'élément de configuration pour la ressource.

Eléments de configuration pour les ressources avec des relations
Si une ressource est liée à d'autres ressources, une modification de celle-ci peut entraîner la création de plusieurs éléments de configuration. L'exemple suivant montre comment AWS Config créer des éléments de configuration pour des ressources ayant des relations.
-
Vous disposez d'une instance Amazon EC2 dont l'ID est
i-007d374c8912e3e90et qui est associée à un groupe de sécurité Amazon EC2,sg-c8b141b4. -
Vous mettez à jour votre instance EC2 pour remplacer le groupe de sécurité par un autre groupe de sécurité,
sg-3f1fef43. -
Comme l'instance EC2 est liée à une autre ressource, elle AWS Config crée plusieurs éléments de configuration, comme dans les exemples suivants :
Cette notification contient la modification apportée à l'élément de configuration pour l'instance EC2 lorsque le groupe de sécurité est remplacé.

Comprendre le champ configurationItemDiff dans les notifications ConfigurationItemChangeNotification Amazon SNS
AWS Config crée un élément de configuration chaque fois que la configuration d'une ressource change (création/mise à jour/suppression). Pour obtenir la liste des types de ressources pris en charge qui AWS Config peuvent enregistrer, consultezTypes de ressource pris en charge. AWS Config utilise Amazon SNS pour envoyer une notification lorsque les modifications se produisent. La charge utile des notifications Amazon SNS inclut des champs pour vous aider à suivre l'évolution des ressources dans une région donnée. AWS
Pour comprendre pourquoi vous recevez une notification ConfigurationItemChangeNotification, consultez les détails configurationItemDiff. Les champs varient en fonction du type de modification et peuvent former différentes combinaisons, comme MISE À JOUR-MISE À JOUR, MISE À JOUR-CRÉATION et SUPPRESSION-SUPPRESSION. Vous trouverez ci-dessous des explications sur certaines combinaisons courantes.
MISE À JOUR-CRÉATION et MISE À JOUR-MISE À JOUR
L'exemple suivant inclut les modifications apportées aux relations directes entre les ressources et les configurations des ressources. Les détails configurationItemDiff révèlent les informations suivantes :
Action effectuée : Une politique gérée présente dans le compte était associée à un rôle AWS Identity and Access Management (IAM).
Opération de base effectuée : MISE À JOUR (mise à jour du nombre d'associations du type de ressource AWS::IAM::Policy dans un compte).
Combinaisons de types de changements :
Changement de la relation directe entre les ressources MISE À JOUR-CRÉATION. Un nouvel attachement ou une nouvelle association a été créé(e) entre une politique IAM et un rôle IAM.
Changement de la configuration des ressources MISE À JOUR-MISE À JOUR. Le nombre d'associations de politiques IAM est passé de 2 à 3 lorsque la politique était associée au rôle IAM.
Exemple de notification MISE À JOUR-CRÉATION et MISE À JOUR-MISE À JOUR configurationItemDiff :
{ "configurationItemDiff": { "changedProperties": { "Relationships.0": { "previousValue": null, "updatedValue": { "resourceId": "AROA6D3M4S53*********", "resourceName": "Test1", "resourceType": "AWS::IAM::Role", "name": "Is attached to Role" }, "changeType": "CREATE" >>>>>>>>>>>>>>>>>>>> 1 }, "Configuration.AttachmentCount": { "previousValue": 2, "updatedValue": 3, "changeType": "UPDATE" >>>>>>>>>>>>>>>>>>>> 2 } }, "changeType": "UPDATE" } }
MISE À JOUR/SUPPRESSION
L'exemple suivant inclut les modifications apportées aux relations directes entre les ressources et les configurations des ressources. Les détails configurationItemDiff révèlent les informations suivantes :
Action effectuée : Une politique gérée présente dans le compte était détachée d'un UTILISATEUR IAM.
Opération de base effectuée : MISE À JOUR (mise à jour de la politique d'autorisations associée au type de ressource AWS::IAM::User).
Combinaisons de types de modifications : modification de la relation directe entre les ressources MISE À JOUR-SUPPRESSION. L'association entre un utilisateur IAM et une politique IAM dans un compte a été supprimée.
Exemple de notification configurationItemDiff MISE À JOUR-SUPPRESSION :
{ "configurationItemDiff": { "changedProperties": { "Configuration.UserPolicyList.0": { "previousValue": { "policyName": "Test2", "policyDocument": "{ "Version": "2012-10-17", "Statement": [ { "Sid": "VisualEditor0", "Effect": "Allow", "Action": "ec2:RunInstances", "Resource": "arn:aws:ec2:*:*:instance/*", "Condition": { "StringLike": { "aws:RequestTag/VPCId": "*" } } } ] }" }, "updatedValue": null, "changeType": "DELETE" >>>>>>>>>>>>>>>>>>>> 3 } }, "changeType": "UPDATE" } }
SUPPRESSION-SUPPRESSION
L'exemple suivant inclut les modifications apportées aux relations directes entre les ressources et les configurations des ressources. Les détails configurationItemDiff révèlent les informations suivantes :
Action effectuée : Un rôle IAM présent dans un compte a été supprimé.
Opération de base exécutée : SUPPRESSION (une ressource du type de ressource AWS::IAM::Role a été supprimée).
Combinaisons de types de modifications : modification de la relation directe entre les ressources et modification de la configuration des ressources SUPPRESSION-SUPPRESSION. La suppression du rôle IAM a également supprimé l'association de la politique IAM au rôle IAM.
Exemple de notification configurationItemDiff SUPPRESSION-SUPPRESSION :
{ "configurationItemDiff": { "changedProperties": { "Relationships.0": { "previousValue": { "resourceId": "ANPAIJ5MXUKK*********", "resourceName": "AWSCloudTrailAccessPolicy", "resourceType": "AWS::IAM::Policy", "name": "Is attached to CustomerManagedPolicy" }, "updatedValue": null, "changeType": "DELETE" }, "Configuration": { "previousValue": { "path": "/", "roleName": "CloudTrailRole", "roleId": "AROAJITJ6YGM*********", "arn": "arn:aws:iam::123456789012:role/CloudTrailRole", "createDate": "2017-12-06T10:27:51.000Z", "assumeRolePolicyDocument": "{"Version":"2012-10-17","Statement":[{"Sid":"","Effect":"Allow","Principal":{"AWS":"arn:aws:iam::123456789012:root"},"Action":"sts:AssumeRole","Condition":{"StringEquals":{"sts:ExternalId":"123456"}}}]}", "instanceProfileList": [], "rolePolicyList": [], "attachedManagedPolicies": [ { "policyName": "AWSCloudTrailAccessPolicy", "policyArn": "arn:aws:iam::123456789012:policy/AWSCloudTrailAccessPolicy" } ], "permissionsBoundary": null, "tags": [], "roleLastUsed": null }, "updatedValue": null, "changeType": "DELETE" } }, "changeType": "DELETE" }
