The EC2 instances are deployed in a virtual network isolated section called Virtual Private Cloud (VPC). The traffic inside VPC is forwarded to a Direct Connect Gateway (DXG). We first created a routing table inside the private subnet of EC2 and directed all traffic destined for the vendor’s payment processing services IP into a VGW.

Think about what information you’ll need to find out which EC2 instance hogged a VPN connection or what service drove up costs on your NAT gateways, and so on. You simply can’t configure flow logging on internet gateways, which would seem like an obvious place to do so. AWS does not let you configure flow logging for internet gateways.

Two exciting new capabilities help you quickly answer any question about your multi-cloud network: Kentik Cloud users can now collect, analyze, and visualize flow logs generated on AWS Transit Gateways. Centralized logs from AWS Transit Gateways don’t require access to flow logs for every attached VPC.

Cato Networks is not aware of any malicious exploitation of its ZTNA using this technique. Details of the attack When a VPN client operates, it begins by creating an encrypted version of the original packet received from its virtual network interface. The malicious server is configured to use itself as the default gateway.

Big Cloud Fabric (Big Switch Networks) - is designed to run Kubernetes in private cloud/on-premises environments. CNI-Genie (Huawei) - CNI is short for “Container Network Interface;” this implementation enables Kubernetes to simultaneously have access to different implementations of the Kubernetes network model in runtime.
