Exam AWS Certified Security - Specialty SCS-C02 topic 1 question 90 discussion

A company's security engineer is developing an incident response plan to detect suspicious activity in an AWS account for VPC hosted resources. The security engineer needs to provide visibility for as many AWS Regions as possible.

Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

  • A. Turn on VPC Flow Logs for all VPCs in the account.
  • B. Activate Amazon GuardDuty across all AWS Regions.
  • C. Activate Amazon Detective across all AWS Regions.
  • D. Create an Amazon Simple Notification Service (Amazon SNS) topic. Create an Amazon EventBridge rule that responds to findings and publishes the findings to the SNS topic.
  • E. Create an AWS Lambda function. Create an Amazon EventBridge rule that invokes the Lambda function to publish findings to Amazon Simple Email Service (Amazon SES).

BD are the correct options here. The keywords here are "developing an incident response plan to detect suspicious activity". There is no better way to develop incident response plan without providing a way for the relevant stakeholders to take actions or respond to suspicious activities. B is an obvious option because GuardDuty can monitor and analyze API calls across all AWS Regions, and network activities found in Amazon CloudTrail Events, Amazon VPC Flow Logs, and DNS Logs. Therefore, option A is not needed since GuardDuty monitoring activities include the VPC Flow Logs. There is no better way to respond to the findings generated by GuardDuty than the services described in option D.

https://docs.aws.amazon.com/guardduty/latest/ug/guardduty_data-sources.html#guardduty_vpc "When you enable GuardDuty, it immediately starts analyzing your VPC flow logs from Amazon EC2 instances within your account. It consumes VPC flow log events directly from the VPC Flow Logs feature through an independent and duplicative stream of flow logs. This process does not affect any of your existing flow logs configuration."

Ok, but why the Detective svc. wasn't a good choice here as it's for developing an incident response plan to 'detect' right?... Agree with option D on the other hand cuz it makes sense..

Selected Answer: AB
A and B are correct for sure. The question does not mention anything about "notifications" or "communications", so D is incorrect. A is correct because the question mentions visibility and detection. You get visibility into network traffic with VPC flow logs. B is correct because because we need to "detection" threats. GaurdDuty is a threat detection capability.

Selected Answer: AB
The most cost-effective combination of steps to meet these requirements. A. Turn on VPC Flow Logs for all VPCs in the account. B. Activate Amazon GuardDuty across all AWS Regions. VPC Flow Logs provides detailed visibility into network traffic with your VPs. This is a cost effective way to monitor and log network activity, which is important for detecting suspicious behaviour. Amazon GuardDuty is a managed threat detection service that continuously monitors for malicious activity and unauthorized behaviour. Activating across all AWS regions ensures comprehensive coverage and visibility into potential security threats.

VPC Flow logs are very expensive.... Guardduty is the right tool to do that with eventbridge

Selected Answer: BD
A. Turn on VPC Flow Logs for all VPCs in the account: While VPC Flow Logs offer detailed information about network traffic, analyzing and storing logs for all VPCs across Regions can incur significant storage and processing costs. C. Activate Amazon Detective across all AWS Regions: Detective focuses on root cause analysis and investigation, which might be overkill for initial detection and notification. Additionally, its per-hour billing model can quickly become expensive for continuous monitoring across multiple Regions. E. Create an AWS Lambda function for publishing findings to SES: While Lambda offers flexibility, creating and maintaining a custom Lambda function specifically for publishing findings can add development and operational overhead compared to the readily available options with EventBridge and SNS.
