Autonomic security for zero trust networks

Abstract

There is a long-standing need for improved cybersecurity through automation of attack signature detection, classification, and response. In this paper, we present experimental test bed results from an implementation of autonomic control plane feedback based on the Observe, Orient, Decide, Act (OODA) framework. This test bed modeled the building blocks for a proposed zero trust cloud data center network. We present test results of trials in which identity management with automated threat response and packet-based authentication were combined with dynamic management of eight distinct network trust levels. The log parsing and orchestration software we created work alongside open source log management tools to coordinate and integrate threat response from firewalls, authentication gateways, and other network devices. Threat response times are measured and shown to be a significant improvement over conventional methods.
