Which of the following approaches achieve this requirement?

Explanations:

A proxy solution can inspect IP packet data by analyzing the traffic passing through it, allowing for malicious content detection. Routing all outbound traffic through the proxy on EC2 allows centralized inspection.

A host-based agent on each EC2 instance can inspect the packet data for malicious content directly on the instance level, providing a detailed and localized inspection approach.

VPC Flow Logs capture metadata about traffic flows but do not provide the content of the IP packets themselves, so they cannot be used for deep content inspection of malicious or invalid data.

ELB access logs record HTTP(S) request details but do not provide the full packet data, and they are more focused on connection information than inspecting IP packets for malicious content.

The CloudWatch Logs agent collects log data from EC2 instances but does not directly perform packet-level inspection. It’s used for logging and not for content inspection of IP packets.
