Design your firewall deployment for Internet ingress traffic flows

Introduction Exposing Internet-facing applications requires careful consideration of what security controls are needed to protect against external threats and unwanted access. These security controls can vary depending on the type of application, size of the environment, operational constraints, or required inspection depth. For some scenarios, running Network Access Control Lists (NACL) and Security Groups (SG) […]

Continuous verification of network compliance using Amazon VPC Network Access Analyzer and AWS Security Hub

Introduction As your distributed application teams operate network infrastructure, it can be challenging for central security, networking, or cloud operations teams to determine whether the correct network controls are in place.

Deployment models for AWS Network Firewall with VPC routing enhancements

Introduction Amazon Virtual Private Cloud (VPC) is a logically isolated virtual network. It has inbuilt network security controls and implicit routing between VPC subnets by design. Network security controls such as security groups (SGs) and network access control lists (ACLs) provide you with options to control network traffic. However these controls operate at network and transport […]

Migrating from Squid Web Proxy to AWS Network Firewall

Introduction Regardless of size or industry, it’s common for organizations to have security and compliance rules for securing internet-bound traffic. AWS customers need control over, and the ability to filter, requests that are initiated by resources in private and public subnets and sent to the internet. This is also known as “egress filtering.” In AWS, […]

Resolve DNS names of Network Load Balancer nodes to limit cross-Zone traffic

Introduction Network Load Balancer (NLB), part of the Elastic Load Balancing Family, is the flagship Layer 4 load balancer for AWS. It offers elastic capacity, high performance, and integration with many other AWS services (such as Amazon EC2 Auto Scaling). NLB is designed to handle millions of requests per second while maintaining ultra-low latency, improving […]
