Discuss Amazon ANS-C01 Exam Topic 1 Question 42

A company is planning to host external websites on AWS. The websites will include multiple tiers such as web servers, application logic services, and databases. The company wants to use AWS Network Firewall. AWS WAR and VPC security groups for network security.

The company must ensure that the Network Firewall firewalls are deployed appropriately within relevant VPCs. The company needs the ability to centrally manage policies that are deployed to Network Firewall and AWS WAF rules. The company also needs to allow application teams to manage their own security groups while ensuring that the security groups do not allow overly permissive access.

What is the MOST operationally efficient solution that meets these requirements?

ADefine Network Firewall firewalls. AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups in code Use AWS CloudFormation to deploy the objects and Initial policies and rule groups. Use CloudFormation to update the AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups. Use Amazon GuardDuty to monitor for overly permissive rules.

BDefine Network Firewall firewalls. AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups in code. Use the AWS Management Console or the AWS CLI to manage the AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups. Use Amazon GuardDuty to invoke an AWS Lambda function to evaluate the configured rules and remove any overly permissive rules.

CDeploy AWS WAFv2 IP sets and AWS WAFv2 web ACLs with AWS CloudFormation. Use AWS Firewall Manager to deploy Network Firewall firewalls and VPC security groups where required and to manage the AWS WAFv2 web ACLs, Network Firewall policies, and VPC security groups.

DDefine Network Firewall firewalls. AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups in code. Use AWS CloudFormation to deploy the objects and initial policies and rule groups. Use AWS Firewall Manager to manage the AWS WAFv2 web ACLs. Network Firewall policies, and VPC security groups. Use Amazon GuardDuty to monitor for overly permissive rules.

D looks good, but managing everything in code feels a bit overwhelming.

Dong 11 months ago

Wait, can GuardDuty really monitor for overly permissive rules?

Kendra 11 months ago

C is interesting, but I'm not sure about using Firewall Manager for everything.

Blythe 11 months ago

I think B is better for flexibility with the AWS CLI.

Kristine 12 months ago

Option A seems solid for automation with CloudFormation.

Ulysses 12 months ago

I practiced a similar question, and I think using GuardDuty to monitor for overly permissive rules is crucial. It’s a good way to ensure security.

I feel like option C might be the best choice since it mentions AWS Firewall Manager, which centralizes management. But I need to double-check the details.

Annelle 1 year ago

I'm not entirely sure, but I think using CloudFormation for deployment is a good practice. It helps with consistency, right?

King 1 year ago

I remember studying about AWS Firewall Manager and how it can help manage security policies across multiple accounts. It seems relevant here.

Ilene 1 year ago

I'm not too familiar with AWS Firewall Manager, so I'll need to do some research on that service to understand how it can be used to manage the Network Firewall and WAF policies. The other parts of the solution seem pretty straightforward, though.

Option D looks like the most comprehensive solution that meets all the requirements. Defining the resources in code and using CloudFormation for deployment, while leveraging Firewall Manager for centralized policy management, seems like the most operationally efficient approach.

Hmm, I'm a bit confused about the different AWS services mentioned and how they all fit together. I'll need to review the details of each one to make sure I understand the differences and how they can be used together.

Lindy 1 year ago

This question seems pretty straightforward. I think the key is to use a combination of CloudFormation and Firewall Manager to centrally manage the security policies and configurations.

Option D looks good, but I'm a little worried about the performance impact of using GuardDuty. Maybe we could use a custom Lambda function instead to keep things snappy.

A: Option D sounds solid, but I agree, GuardDuty might slow things down.

Lashaun 2 years ago

Hmm, this is a tough one. I'm leaning towards option C because it seems to offer the most centralized management of the security components. But I'm open to hearing what the other candidates think.

I agree with Douglass. Option D seems to cover all the requirements effectively.

Douglass 2 years ago

I think the most operationally efficient solution is option D.

Fannie 2 years ago

Option D looks good, but I'm not sure about using Amazon GuardDuty to monitor for overly permissive rules. Wouldn't it be better to use a more robust solution like AWS Config or AWS Security Hub?

Kattie 2 years ago

This seems like a pretty straightforward question. I think option D is the best solution as it allows for centralized management of the security policies while still giving the application teams the ability to manage their own security groups.

Jacquline 2 years ago

↳ replying to Kattie

It's important to strike a balance between centralized control and allowing application teams some autonomy.
