Zorluk: KolaySecurity Monitoring and Threat Detection

A company's security team needs to monitor network traffic entering and leaving their Amazon VPC. They want to identify potential security threats, detect anomalous traffic, and capture details about the IP traffic flowing through the network interfaces. Which two actions should the solutions architect recommend to implement this security monitoring? (Select TWO.)

  1. Enable VPC Flow Logs on the target VPC to capture IP traffic details for network interfaces.Cevap
  2. Publish the flow log data to an Amazon CloudWatch Logs log group to enable querying and analysis.Cevap
  3. C
    Deploy AWS Shield Advanced on the VPC subnets to inspect and block Layer 7 SQL injection attacks.
  4. D
    Configure stateful Network ACLs at the subnet level to automatically track and log session state for all inbound traffic.
  5. E
    Enable AWS WAF on the subnet route tables to monitor network-layer routing anomalies.

Cevap

Enable VPC Flow Logs on the target VPC to capture IP traffic details for network interfaces, and publish the flow log data to an Amazon CloudWatch Logs log group to enable querying and analysis.
The correct combination of actions is to enable VPC Flow Logs on the target VPC to capture metadata about IP traffic, and to publish those logs to Amazon CloudWatch Logs (or Amazon S3) for querying and analysis. This aligned architectural approach captures network-level traffic data without agent overhead and allows direct querying to discover anomalous traffic.

Adım Adım Çözüm

1
Identify the primary source of VPC network traffic metadata.
VPC Flow Logs captures packet metadata (source, destination, protocol, port, packets, bytes) at the network interface level.
This provides the underlying data needed to audit network flows and detect threats.
2
Determine where to store and analyze the captured network traffic flow data.
Publishing to Amazon CloudWatch Logs or Amazon S3 allows for query execution and integration with anomaly detection tools.
VPC Flow Logs must be exported to a destination like CloudWatch Logs or Amazon S3 to be queried and analyzed.

Anahtar Kavram

VPC Flow Logs capture network traffic metadata at the VPC, subnet, or elastic network interface level, and can be published to CloudWatch Logs or Amazon S3 for security monitoring.
