Rapidly cyber-attacks are increasing, it’s very crucial to protect your application with a firewall. AWS Network firewalls protect your application from threats like malware, botnets, and DDoS attacks while providing advanced access control.
AWS Network Firewall:-
AWS Network Firewall is a software-based highly available managed firewall service that makes it easy to deploy essential network protections for all of your VPCs and scale automatically with your network traffic, without worrying about deploying and managing any underlying infrastructure. AWS Network Firewall deploy at the edge of your AWS VPC so it can inspect and control all ingress and egress traffic.
AWS Network Firewall provides some extra features like deep packet inspection, application protocol detection, domain name filtering, and an intrusion prevention system. It also offers web filtering that can stop traffic to known bad URLs and monitor fully qualified domain names. AWS Network Firewall’s stateful firewall can incorporate context from traffic flows, like tracking connections and protocol identification, to enforce policies such as preventing your VPCs from accessing domains using an unauthorized protocol.
Benefits of the AWS Network Firewall:
- Policy management is consistent across VPCs and accounts.
- Fine-grained controls for access provide flexible protection.
- It is easy to manage the infrastructure for High Availability.
How it works:
AWS Network Firewall is a stateful, managed, network firewall and provide ids services for AWS. It can be associated with other AWS Services like an internet gateway, a NAT gateway, a VPN, or a transit gateway.
AWS Firewall Manager
AWS Firewall Manager is a security management service that secures your virtual networks at scale inside the Amazon Cloud. It allows you to centrally configure Managed Rules for AWS Network Firewall policies across multiple AWS accounts and applications.
Adding new application and resources in to compliance by enforcing a common set of rules are bit easy.
AWS Firewall Manager allows you to have a single service to build firewall rules, create security policies, and enforce them in a consistent, hierarchical manner across your entire infrastructure, from a central administrator account of your AWS Organization.
Benefits of AWS Firewall Manager are:
Manage firewall rules to multiple accounts: –
AWS Firewall Manager is integrated with AWS Organizations so that from one place you can manage AWS WAF rules, AWS Shield Advanced Protection, Security Groups, AWS Network Firewall rules, and Amazon Route 53 Resolver DNS Firewall rules.
Manage rules easily deploy across accounts:
Pre-configured WAF rules or from an AWS Marketplace seller can be deployed consistently across your ALBs, API Gateways, and CloudFront infrastructure with just a few clicks in the interface.
Centrally deploy AWS Network Firewall protections for across VPCs:
The security administrator can deploy a baseline set of VPC security group rules for EC2 instances, ALBs, and ENIs in your VPCs. From a single place, you can also audit any existing security groups in your VPCs and remediate them. You can allow Firewall Manager to deploy rules for AWS Network Firewall across your VPCs in your organization to control traffic leaving and entering your network. Firewall Manager can also associate your VPCs with Route 53 Resolver DNS Firewall rules to block DNS queries.
