Surveillance de vos clés de chiffrement pour le service Amazon Bedrock

Lorsque vous utilisez une clé gérée par le AWS KMS client avec vos ressources Amazon Bedrock, vous pouvez utiliser AWS CloudTrailAmazon CloudWatch Logs pour suivre les demandes auxquelles Amazon Bedrock envoie. AWS KMS

Voici un exemple d' AWS CloudTrail événement permettant de CreateGrantsurveiller les AWS KMS opérations appelées par Amazon Bedrock pour créer une subvention principale :
