Running a complex network is not an easy job. In addition to simply keeping it up and running, you need to keep an ever-watchful eye out for unusual traffic patterns or content that could signify a network intrusion, a compromised instance, or some other anomaly. VPC Traffic Mirroring Today we are launching VPC Traffic Mirroring. This is a new feature that you can use with your existing Virtual Private Clouds (VPCs) to capture and inspect network traffic at scale. This will allow you to: Detect Network & Security Anomalies – You can extract traffic of interest from any workload in a VPC and route it to the detection tools of your choice. You can detect and respond to attacks more quickly than is possible with traditional log-based tools. You can think of VPC Traffic Mirroring as a “virtual fiber tap” that gives you direct access to the network packets flowing through your VPC. As you will soon see, you can choose to capture all traffic or you can use filters to capture the packets that are of particular interest to you, with an option to limit the number of bytes captured per packet. You can use VPC Traffic Mirroring in a multi-account AWS environment, capturing traffic from VPCs spread across many AWS accounts and then routing it to a central VPC for inspection.
