AWS Firewall Manager - Naukri Code 360

Introduction

AWS Firewall Manager is a security management service that allows you to set up and maintain firewall rules for all of your AWS Organizations accounts and apps from one location. New applications and resources are created all the time. By adhering to a single set of security guidelines, the Firewall Manager makes it simple to bring them into compliance.

In this blog, we will learn about AWS Firewall Manager.

So, let's begin!

What is the AWS Firewall Manager

AWS Firewall Manager simplifies your administration and maintenance tasks across multiple accounts and resources for various protections, including AWS WAF, AWS Shield Advanced, Amazon VPC security groups, AWS Network Firewall, and Amazon Route 53 Resolver DNS Firewall. With Firewall Manager, you set up your protections just once, and the service automatically applies them across your accounts and resources, even as you add new accounts and resources.

Benefits of AWS Firewall Manager

Manage firewall rules across all of your accounts with ease

AWS Firewall Manager and AWS Organizations are linked, so you can manage your Amazon VPCs' AWS WAF rules, AWS Shield Advanced protection, security groups, and AWS Network Firewall rule. You can manage Amazon Route 53 Resolver DNS Firewall rules and AWS Marketplace third-party firewall rules from a single location. You may create policies, organize rules, and apply them centrally across your whole infrastructure. You can, for example, delegate the creation of account-specific rules while still adhering to global security standards across all accounts.

Ensure compliance with existing and new applications

AWS Firewall Manager automatically applies the mandatory security policies you set across existing and newly created resources. The service detects new resources as they are created across accounts. Consider the Office of Foreign Assets Control (OFAC) regulations of the US Department of Treasury. In that situation, To block traffic from embargoed countries, you can use Firewall Manager to create an AWS WAF rule that spans your Application Load Balancer, API Gateway, and Amazon CloudFront accounts. When new resources are developed, they will be automatically added to the policy scope.

Easily deploy managed rules across accounts

AWS Firewall Manager interfaces with AWS WAF Managed Rules, making it simple to deploy pre-configured WAF rules to your apps. With only a few clicks in the interface, you can select a Managed Rule from an AWS Marketplace Seller and deploy it across your Application Load Balancer, API Gateway, and Amazon CloudFront infrastructure. Subscribing to an AWS Marketplace Managed Rule for WAF that includes CVE patch updates, you can quickly defend your entire organization from zero-day vulnerabilities. You may use AWS Firewall Manager to automatically protect your accounts against DDoS attacks using Advanced Shield protections, such as UDP reflection, SYN flood, DNS query flood, and HTTP flood attacks.

Centrally deploy protections for your VPCs

For EC2 instances, ALBs, and ENIs in your Amazon VPCs, your security administrator can utilize Firewall Manager to build a baseline set of VPC security group rules. You may also audit any existing security groups in your VPCs for too permissive policies and rectify them all from one location. To limit traffic entering and leaving your network, you may use Firewall Manager to implement AWS Network Firewall rules across your organization's VPCs. In addition, you can use Firewall Manager to associate your VPCs with Route 53 Resolver DNS Firewall rules to prevent DNS requests for known dangerous domains while allowing inquiries for trusted domains.
