SCS-C02 Exam Dumps : AWS Certified Security - Specialty

The solution to receiving automated email notifications when AWS access keys are detected on code repository sites is to use Amazon EventBridge with Amazon GuardDuty findings. Specifically, creating an EventBridge rule that targets Amazon GuardDuty findings, particularly theUnauthorizedAccess:IAMUser/InstanceCredentialExfiltrationfinding type, allows for the detection of potential unauthorized use or exposure of AWS credentials. When such a finding is detected, EventBridge can then trigger an action to send a notification via Amazon Simple Notification Service (Amazon SNS). By configuring an SNS topic to send emails, stakeholders can be promptly informed of such security incidents. This approach leverages AWS's native security and monitoring services to provide timely alerts with minimal operational overhead, ensuring that the company can respond quickly to potential security breaches involving exposed AWS credentials.

The fastest way to identify the federated user who terminated a production Amazon EC2 instance is to filter the IAM CloudTrail event history for the TerminateInstances event and identify the assumed IAM role. Then, review the AssumeRoleWithSAML event call in CloudTrail to identify the corresponding username. This method does not require any additional tools or queries, and it directly links the IAM role with the federated user.

Option A is incorrect because the role session name may not be the same as the federated user name, and it may not be unique or descriptive enough to identify the user.

Option C is incorrect because the IAM Access Advisor tab only shows when a role was last accessed, not by whom or for what purpose. It also does not show the specific time of access, only the date.

Option D is incorrect because using Amazon Athena to run SQL queries on the IAM CloudTrail logs is not the fastest way to identify the federated user, as it requires creating a table schema and running multiple queries. It also assumes that the federation is done using web identity providers, not SAML providers, as indicated by the AssumeRoleWithWebIdentity event. References:
