Abstract : Access Control (AC) is a well known mechanism that allows access restriction to resources. Nevertheless, it does not provide notification when a resource is retransmitted to an unauthorized third party. To overcome this issue, one can use mechanisms such as Data Loss/Leak Prevention (DLP) or Transmission Control (TC). These mechanisms are based on policies that are defined by security experts. Unfortunately, these policies can contradict existing AC rules, leading to security leakage (i.e. a legitimate user is allowed to send a resource to someone who has no access rights in the AC). In this article, we aim at creating TC policies that are compliant with existing AC policies. To do so, we use a mapping mechanism that generates TC rules directly from existing AC policies. Thanks to the generated rules, our solution can make inferences to improve existing AC and enhance security knowledge between infrastructures.
