Amazon Web Services SCS-C02 Exam With Confidence Using Practice Dumps

The correct answer is D. Enable CloudTrail to monitor data events for read and write operations to S3 buckets.

According to the AWS documentation1, CloudTrail data events are the resource operations performed on or within a resource. These are also known as data plane operations. Data events are often high-volume activities. For example, Amazon S3 object-level API activity (such as GetObject, DeleteObject, and PutObject) is a data event.

By default, trails do not log data events. To record CloudTrail data events, you must explicitly add the supported resources or resource types for which you want to collect activity.For more information, see Logging data events in the Amazon S3 User Guide2.

In this case, the security team wants EventBridge to watch for the s3:PutObjectAcl API invocation logs from CloudTrail.This API uses the acl subresource to set the access control list (ACL) permissions for a new or existing object in an S3 bucket3. This is a data event that affects the S3 object resource type. Therefore, the security team must enable CloudTrail to monitor data events for read and write operations to S3 buckets in order to invoke an EventBridge event for this API call.

The other options are incorrect because:

A. Modifying the EventBridge event pattern by selecting Amazon S3 and All Events as the event type will not capture the s3:PutObjectAcl API call, because this is a data event and not a management event. Management events provide information about management operations that are performed on resources in your AWS account.These are also known as control plane operations4.

B. Modifying the EventBridge event pattern by selecting Amazon S3 and Bucket Level Operations as the event type will not capture the s3:PutObjectAcl API call, because this is a data event that affects the S3 object resource type and not the S3 bucket resource type.Bucket level operations are management events that affect the configuration or metadata of an S3 bucket5.

C. Enabling CloudTrail Insights to identify unusual API activity will not help the security team monitor new S3 objects or changes to any S3 bucket policy or setting that result in public access.CloudTrail Insights helps AWS users identify andrespond to unusual activity associated with API calls and API error rates by continuously analyzing CloudTrail management events6. It does not analyze data events or generate EventBridge events.

Enable VPC Flow Logs:

VPC flow logs capture details about the network traffic in your VPC, including both accepted and rejected traffic.

Configure the flow logs to capture traffic for the subnet where the affected EC2 instances are located.

Filter Rejected Traffic:

In the flow log configuration, ensure that you capture rejected traffic (log-status = REJECT).

This will provide a record of instances that attempted to communicate on TCP port 2905 and were blocked by the NACL rule.

Analyze Flow Logs:

Search the flow log records for entries where:

destination-port = 2905

log-status = REJECT

This will help identify the specific EC2 instances attempting to communicate on TCP port 2905.

Advantages of Using VPC Flow Logs:

Cost-effective: No additional infrastructure or services are required.

Scalable: Automatically captures traffic across the subnet without manual intervention.

Detailed Logs: Provides granular details about the rejected traffic.

The best solution to meet the company's requirements of offering an alternative login method while securely protecting player credentials and reducing the burden of password resets is to use Amazon Cognito with user pools. Amazon Cognito provides a fully managed service that facilitates the authentication, authorization, and user management for web and mobile applications. By configuring Amazon Cognito user pools to federate access with third-party Identity Providers (IdPs), such as social media platforms or Google, the company can allow users to sign in through these external IdPs, thereby eliminating the need for traditional username and password logins. This not only enhances user convenience but also offloads the responsibility of managing user credentials and the associated challenges like password resets to Amazon Cognito, thereby reducing the burden on the company's customer service team. Additionally, Amazon Cognito integrates seamlessly with other AWS services and follows best practices for security and compliance, ensuring that the player's credentials are protected.
