Awen's Adventures in Miniature Wonderland
One of many recent additions to Awen Collective's asset discovery tool, Dot, is the ability to parse and analyse network traffic of the Z21 protocol. Chances are you know a thing or two about model trains if "Z21" sounds familiar. Indeed, Z21 is a German organisation that maintains proprietary technologies to monitor and control miniature locomotives.
PCAPs - The World of Network Traffic
How does one get started obtaining pcaps in an enterprise environment? Having each endpoint on your network store the traffic they detect is likely both heavy on resources and difficult to manage and aggregate. On the other hand, having your network perimeter devices such as your firewalls do the same would mean capturing unfiltered traffic or compelling an already-preoccupied machine to work overtime to either analyse packets itself or forward packets to another machine for monitoring.
