Difficulty: MediumThreat Detection and Vulnerability Management

A SaaS provider hosts its web application on Amazon EC2 instances and stores container images in Amazon Elastic Container Registry (Amazon ECR). The security team needs to implement automated tools to accomplish two tasks:
1. Continually scan the EC2 instances and container images for software vulnerabilities and unintended network exposure.
2. Monitor AWS account activity and network traffic to detect anomalous behavior, potential unauthorized access, and malicious threats.

Which two AWS services should the company use to meet these requirements? (Select two.)

  1. Amazon InspectorAnswer
  2. Amazon GuardDutyAnswer
  3. C
    AWS Artifact
  4. D
    Amazon CloudWatch
  5. E
    AWS Key Management Service (AWS KMS)

Answer

Amazon Inspector and Amazon GuardDuty should be used to scan for software vulnerabilities and detect malicious threats, respectively.
Amazon Inspector automatically and continuously scans EC2 instances and ECR container images for software vulnerabilities and unintended network exposure. Amazon GuardDuty provides continuous threat detection by monitoring AWS account activity and network traffic to identify potential malicious activity.

Step-by-Step Solution

1
Identify the service responsible for scanning EC2 instances and ECR container images for software vulnerabilities and network exposure.
Amazon Inspector performs vulnerability scanning on Amazon EC2 instances and Amazon ECR images.
This meets the first requirement of detecting software vulnerabilities and unintended network exposure.
2
Identify the service responsible for monitoring AWS account activity and network traffic to detect anomalous or malicious behavior.
Amazon GuardDuty provides continuous threat detection by analyzing events and log data.
This meets the second requirement of detecting threats, unauthorized access, and malicious activity.
