Amazon uses Tiros to validate WAN network segmentation hourly
Overview
Amazon Web Services says it uses Tiros, its automated-reasoning tool for network connectivity, to validate network segmentation across all modeled paths in a Cloud WAN deployment.
Amazon Science describes the method in a first-party post.
Tiros collects the customer's Cloud WAN configuration, including route tables, attachments and policy documents, and runs the check as often as every hour. Amazon says it does this instead of relying on packet sampling. The check confirms that no path exists between segments the policy declares should be isolated.

AIAmazon Web Services describes using Tiros, its automated-reasoning tool for network connectivity, to validate network segmentation across all modeled paths. The approach analyzes a deployed Cloud WAN configuration's route tables, attachments, and policy documents as frequently as every hour, rather than relying on packet sampling. Tiros checks that no path exists between segments that the policy declares should be isolated.
