Secure Amazon container workloads using container attribute-based rules in AWS Network Firewall

Today, you can use AWS Network Firewall to protect traffic flowing to and from containerized applications on Amazon Elastic Kubernetes Service (Amazon EKS) and Amazon Elastic Container Service (Amazon ECS) clusters. If you run AI and machine learning (ML) workloads on Amazon EKS—such as model inference, RAG pipelines, or JupyterHub—your containerized workloads require the same […]

Prevent data exfiltration: AWS egress controls for cloud workloads

When securing an Amazon Web Services (AWS) environment, teams naturally prioritize inbound controls, firewalls, WAFs, and access policies, because that’s where the most visible threats originate. Outbound traffic, on the other hand, tends to get less attention. It’s often left open by default to avoid breaking application dependencies and because the risk feels less immediate. […]

Why and how to migrate to a Transit Gateway-attached AWS Network Firewall

AWS Network Firewall now supports native attachment to AWS Transit Gateway. Customers commonly use Transit Gateway to route traffic from Amazon Virtual Private Cloud (Amazon VPC) networks to a centralized inspection VPC (a VPC dedicated to hosting firewall endpoints for traffic inspection) where their network firewall endpoints are deployed. This centralized deployment model reduces the […]

Simplifying policy management with URL and Domain Category filtering on AWS Network Firewall

Network administrators face a persistent challenge: maintaining domain blocklists and allowlists that keep pace with the internet. New websites and services emerge daily, and keeping these lists current requires constant manual updates that leave gaps in coverage. This challenge intensifies when managing access to rapidly evolving categories like AI services, where new tools launch on […]

Security posture improvement in the AI era

It’s only been a few weeks since Anthropic announced the Claude Mythos Preview model and launched Project Glasswing with AWS and other leading organizations. This has generated a lot of discussion about the future of cybersecurity and what the ever-increasing capabilities of foundation models mean to organizations. As AWS CISO Amy Herzog pointed out in […]

Real-time malware defense: Leveraging AWS Network Firewall active threat defense

Cyber threats are evolving faster than traditional security defense can respond; workloads with potential security issues are discovered by threat actors within 90 seconds, with exploitation attempts beginning within 3 minutes. Threat actors are quickly evolving their attack methodologies, resulting in new malware variants, exploit techniques, and evasion tactics. They also rotate their infrastructure—IP addresses, […]

Simplify cloud security with managed rules from AWS Marketplace for AWS Network Firewall

AWS Network Firewall now supports managed rules curated by AWS Partners—giving you pre-built threat intelligence and security controls that reduce the need to create and maintain your own rule sets. This new capability helps organizations strengthen their network security posture with continuously updated AWS partner managed protection. What are managed rules from AWS Marketplace for […]

Analyze AWS Network Firewall logs using Amazon OpenSearch dashboard

Amazon CloudWatch and Amazon OpenSearch Service have launched a new dashboard that simplifies the analysis of AWS Network Firewall logs. Previously, in our blog post How to analyze AWS Network Firewall logs using Amazon OpenSearch Service we demonstrated the required services and steps to create an OpenSearch dashboard. The new dashboard removes these extra steps […]

Enhance TLS inspection with SNI session holding in AWS Network Firewall

AWS Network Firewall is a managed firewall service that filters and controls network traffic in Amazon Virtual Private Cloud (Amazon VPC). Unlike traditional network controls such as security groups or network access control lists (NACLs), Network Firewall can inspect and make decisions based on information from higher layers of the OSI model, including the Transport […]
