Question

Which AWS service is deployed to VPCs and provides protection from common network threats?

A. AWS Shield
B. AWS WAF
C. AWS Network Firewall
D. AWS Firewall Manager

Answer

C. AWS Network Firewall

Explanation

The correct answer to the question is C. AWS Network Firewall.

AWS Network Firewall is the AWS service that is deployed to VPCs and provides protection from common network threats. Let’s dive into a detailed explanation of this service:

AWS Network Firewall:

  • AWS Network Firewall is a managed network firewall service provided by AWS.
  • It allows you to deploy stateful firewall protections for your Amazon Virtual Private Cloud (VPC) environments.
  • With AWS Network Firewall, you can define customizable network security rules to filter traffic and protect your VPCs from common network threats, such as Distributed Denial of Service (DDoS) attacks, port scanning, and IP spoofing.
  • It integrates with other AWS services, such as AWS CloudWatch for monitoring and AWS Firewall Manager for centralized management of firewall rules.
  • AWS Network Firewall supports rule-based traffic inspection and filtering at the stateful 5-tuple (source IP, source port, destination IP, destination port, protocol) level.
  • It provides an additional layer of security to protect your applications and resources within your VPCs.

Now, let’s briefly explain why the other options are not the correct answers:

A. AWS Shield:

  • AWS Shield is a managed Distributed Denial of Service (DDoS) protection service provided by AWS.
  • While AWS Shield helps protect against DDoS attacks, it is not specifically deployed to VPCs for network threat protection.

B. AWS WAF:

  • AWS WAF (Web Application Firewall) is a web application firewall service provided by AWS.
  • It helps protect web applications from common web-based attacks, such as SQL injection and cross-site scripting (XSS).
  • While AWS WAF provides security for web applications, it does not provide network threat protection for VPCs.

D. AWS Firewall Manager:

  • AWS Firewall Manager is a service that simplifies the management of AWS WAF rules across multiple accounts and resources.
  • It allows you to centrally configure and manage firewall rules for AWS WAF.
  • While AWS Firewall Manager is related to firewall rule management, it is not specifically deployed to VPCs for network threat protection.

To summarize, if you need protection from common network threats for your VPCs, you should deploy AWS Network Firewall. It allows you to define customizable network security rules and provides stateful firewall protections to safeguard your VPC environments from various network-based attacks.
