Under increased cybersecurity concerns, a company is deploying a near real-time intrusion detection system (IDS) solution. A system must be put in place as soon as possible. The architecture consists of many AWS accounts, and all results must be delivered to a central location.
Which solution will meet this requirement, while minimizing downtime and costs?

A. Deploy a third-party vendor solution to perform deep packet inspection in a transit VPC.
B. Enable VPC Flow Logs on each VPC. Set up a stream of the flow logs to a central Amazon Elasticsearch cluster.
C. Enable Amazon Macie on each AWS account and configure central reporting.
D. Enable Amazon GuardDuty on each account as members of a central account.
