Which AWS service can be used to securely store these logs?
Amazon EC2 VPC Flow Logs
Amazon CloudWatch Logs
Amazon CloudSearch
AWS CloudTrail
Explanations:
Amazon EC2 VPC Flow Logs capture network traffic data between resources in a VPC, not application-level logs.
Amazon CloudWatch Logs is a fully managed service designed to collect and store application logs, making it suitable for centralized storage of logs.
Amazon CloudSearch is a managed search service, not designed for log storage. It is used for indexing and searching data, not for storing logs.
AWS CloudTrail is used for auditing and recording AWS API calls, not for storing application logs. It provides governance and compliance data, not application-level logs.
