A company wants to protect data at rest in Amazon S3 using client-side encryption. The application will run on Amazon EC2 instances. Which approach meets these requirements?

A company runs a critical web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The application processes sensitive customer data. The Security team has enabled VPC Flow Logs, CloudTrail, and GuardDuty. Recently, the team received a GuardDuty finding indicating a potential SSH brute force attack originating from an external IP address 203.0.113.50 targeting one of the EC2 instances. The Security Engineer needs to automatically isolate the affected instance and capture forensic evidence for analysis. The company has strict requirements: the instance must be isolated immediately, and a snapshot of the EBS volume must be taken before any remediation actions are taken. The instance is part of an Auto Scaling group, and the Security Engineer wants to minimize manual intervention. The Security Engineer has access to AWS Systems Manager and AWS Lambda. Which combination of steps should the Security Engineer implement to meet the requirements?

A company uses Amazon GuardDuty and AWS Security Hub. The security team has configured a custom insight in Security Hub to track findings related to S3 bucket exposures. They want to automatically remediate these findings by applying an S3 bucket policy that blocks public access. The team has created a Lambda function that applies the bucket policy and configured Security Hub to send findings to the Lambda function via a custom action. However, when a new finding is generated, the Lambda function is invoked but fails to apply the policy because it does not have permission to modify the S3 bucket. The Lambda function's execution role has permissions to modify S3 bucket policies, but the function is in the same account as the bucket. What should the team check?
