B. AWS Shield Advanced provides advanced DDoS protection for the NLB, making it the appropriate choice for protecting against large and sophisticated DDoS attacks at the network layer. C. AWS WAF is designed to provide protection at the application layer, making it suitable for securing the API Gateway against web exploits like SQL injection. A. AWS WAF is not compatible with NLB as it operates at the application layer, whereas NLB operates at the transport layer. D. While GuardDuty helps detect threats, it does not directly protect against web exploits or DDoS attacks. Shield Standard focuses on edge resources, not specifically NLBs. E. Shield Standard provides basic DDoS protection for edge resources, but it does not directly protect the NLB or address web exploits at the application layer.

AWS Shield protects against Layer 3 and 4 attacks through NLB and AWS WAF protects against Layer 7 attacks through API Gateway.

I did not get this right initially, but when I looked it up, it became clear. Basically any device that acts at network level - Shield (Layer 4 devices, maybe capable of layer 7 as well). For example, NLB, ELB, CF, Route 53. Any device that works on HTTP/HTTPS/SFTP level(Layer 7 services) ==> WAF , which is ALB, API Gateway. a Layer 7 device are not capable of layer 4 sevices, and they rely on underlying hardware/firmware(OR in this case of Software defined networking, Software) to do that.

Shield advanced does not protect against SQL injection. That is what WAF is for. GuardDuty is not the right tool here. Answers are B and C bro.

B) Use AWS Shield Advanced with the NLB C) Use AWS WAF to protect Amazon API Gateway The key reasons are: AWS Shield Advanced provides expanded DDoS protection against larger and more sophisticated attacks Using it with the NLB helps protect against network floods WAF still provides critical protection against exploits at the API lay

Selected Answer: BC

NLB is a Lyer 3/4 component while WAF is a Layer 7 protection component. That is why WAF is only available for Application Load Balancer in the ELB portfolio. NLB does not terminate the TLS session therefore WAF is not capable of acting on the content. I would consider using AWS Shield at Layer 3/4. https://repost.aws/questions/QU2fYXwSWUS0q9vZiWDoaEzA/nlb-need-to-attach-aws-waf

Selected Answer: C

• A. Use AWS WAF to protect the NLB. INCORRECT, cos' WAF not integrate with network LB • B. Use AWS Shield Advanced with the NLB. YES. AWS Shield Advanced provides additional protections against more sophisticated and larger attacks for your applications running in AWS. The doubt is : why apply the protection in the NLB when the facing of the app. is the API Gateway?, because Shield shoud be in front of the communications, not behind. Nevertheless, this is the best option. • C. Use AWS WAF to protect Amazon API Gateway. YES, https://aws.amazon.com/es/waf/faqs/ • D. Use Amazon GuardDuty with AWS Shield Standard INCORRECT, GuardDuty not prevent attacks. •E. Use AWS Shield Standard with Amazon API Gateway. INCORRECT. It could be, in principle, a good option, cos' it's in front of the gateway, but the questions said explicity: "wants to detect and mitigate large, sophisticated DDoS attacks", and Standard not provide this feature.

for those who select A, it is wrong, WAF is Layer 7, it only support ABL, APIGateway, CloudFront,COgnito User Pool and AppSync graphQL API (https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html). NLB is NOT supported. Answer is BC

A and B are the best options to provide the greatest protection for the platform against web vulnerabilities and large, sophisticated DDoS attacks. Option A: Use AWS WAF to protect the NLB. This will provide protection against common web vulnerabilities such as SQL injection. Option B: Use AWS Shield Advanced with the NLB. This will provide additional protection against large and sophisticated DDoS attacks.

A and C are the best options for protecting the platform against web vulnerabilities and detecting and mitigating large and sophisticated DDoS attacks. A: AWS WAF can be used to protect the NLB from web vulnerabilities such as SQL injection. C: AWS WAF can be used to protect Amazon API Gateway and also provide protection against DDoS attacks. B: AWS Shield Advanced is used to protect resources from DDoS attacks, but it is not specific to the NLB and may not provide the same level of protection as using WAF specifically on the NLB. D and E: Amazon GuardDuty and AWS Shield Standard are primarily used for threat detection and may not provide the same level of protection as using WAF and Shield Advanced.

The best protection for the platform would be to use A and C together because it will protect both the NLB and the API Gateway from web vulnerabilities and DDoS attacks.

WS Shield Advanced can help protect your Amazon EC2 instances and Network Load Balancers against infrastructure-layer Distributed Denial of Service (DDoS) attacks. Enable AWS Shield Advanced on an AWS Elastic IP address and attach the address to an internet-facing EC2 instance or Network Load Balancer.https://aws.amazon.com/blogs/security/tag/network-load-balancers/

Regional resources You can protect regional resources in all Regions where AWS WAF is available. You can see the list at AWS WAF endpoints and quotas in the Amazon Web Services General Reference. You can use AWS WAF to protect the following regional resource types: Amazon API Gateway REST API Application Load Balancer AWS AppSync GraphQL API Amazon Cognito user pool You can only associate a web ACL to an Application Load Balancer that's within AWS Regions. For example, you cannot associate a web ACL to an Application Load Balancer that's on AWS Outposts.

***CORRECT*** A. Use AWS WAF to protect the NLB. C. Use AWS WAF to protect Amazon API Gateway. AWS WAF is a web application firewall that helps protect web applications from common web exploits such as SQL injection and cross-site scripting attacks. By using AWS WAF to protect the NLB and Amazon API Gateway, the company can provide an additional layer of protection for its cloud communications platform against these types of web exploits.

About AWS Shield Advanced and Amazon GuardDuty AWS Shield Advanced is a managed DDoS protection service that provides additional protection for Amazon EC2 instances, Amazon RDS DB instances, Amazon Elastic Load Balancers, and Amazon CloudFront distributions. It can help detect and mitigate large, sophisticated DDoS attacks, "but it does not provide protection against web exploits like SQL injection." Amazon GuardDuty is a threat detection service that uses machine learning and other techniques to identify potentially malicious activity in your AWS accounts. It can be used in conjunction with AWS Shield Standard, which provides basic DDoS protection for Amazon EC2 instances, Amazon RDS DB instances, and Amazon Elastic Load Balancers. However, neither Amazon GuardDuty nor AWS Shield Standard provides protection against web exploits like SQL injection. Overall, the combination of using AWS WAF to protect the NLB and Amazon API Gateway provides the most protection against web exploits and large, sophisticated DDoS attacks.

Your answer is wrong. Sophisticated DDOS = Shield Advanced (DD0S attacks the front!) What happens if your load balances goes down? Your API gateway is on the BACK further behind the NLB. SQL Protect that with the WAF B and C are right.
