AWS Firewall Manager

Securing Your Cloud with AWS Firewall Manager

Secure Your Cloud

Introduction

In the rapidly evolving cloud computing landscape, security remains top priorities for businesses of all sizes. With the continuous rise of sophisticated cyber threats and complex network architectures, organizations need robust solutions to safeguard their cloud Environments. One such solutions offered by AWS is the AWS Firewall Manager (or AWS Network Firewall). Which is a tool designed to simplify firewall management and enhance overall security posture.

What Is Firewall Manager?

Firewall Manager is a centralized security management service that allows you to set and administer firewall rules across all of your accounts and applications from a single location. It provides a unified approach to firewall management. Think of AWS firewall Manager as the central command centre of your cloud security. It lets you manage and enforce consistent security policies across multiple AWS accounts and resources, including WAF, Network Firewalls, VPC security groups, and others.

Benefits of AWS Firewall Manager

Simplify management of firewall rules across your accounts: AWS Firewall Manager is linked with AWS Organizations, allowing you to manage your Amazon VPC’s AWS WAF rules, AWS Shield Advanced protections, security groups, AWS Network Firewall rules, and Amazon Route 53 Resolver DNS Firewall rules from a single location.

Ensure compliance of existing and new applications: AWS Firewall Manager applies the mandatory security policies you establish across existing and newly generated resources automatically.

Easily deploy managed rules across accounts: With just a few clicks in the interface, you can select a Managed Rule from an AWS Marketplace Seller and deploy it uniformly throughout your Application Load Balancer, API Gateway, and Amazon CloudFront architecture.

Centrally deploy protections for your VPCs: Security administrators can use Firewall Manager to establish a baseline set of VPC security group rules in Amazon VPCs for EC2 instances, Application Load Balancers (ALBs), and Elastic Network Interfaces (ENIs).

Ensure compliance of existing and new applications: AWS Firewall Manager (AWS Network Firewall) automatically enforces mandatory security policies that you define across and newly created resources.

How Firewall Manager works

You manage your Firewall Manager policies with your Firewall Manager administrator account.

Firewall Manager sets the Firewall Manager administrator account as the AWS Organizations Delegated Administrator for Firewall Manager when you create it.

This gives the Firewall Manager access to the organizational units (OUs) you use to define the scope of your Firewall Manager policies.

It generates findings for out-of-compliance resources and detects assaults, which it sends to AWS Security Hub.

Conclusion

AWS Firewall Manager stands out as a robust solution for organizations seeking to streamline and fortify their cloud security. By providing centralized management, automated rule deployment. This brings us to the end of this blog.
