Network segmentation is a security measure that partitions a network into sections or segments to restrict the movement of a cyber attacker and make it difficult for her to gain access to valuable network resources. This threat-mitigating practice has been recommended by several information security agencies. While it is clear that segmentation is a critical defensive mitigation against cyber threats, it is not clear how to properly apply it. Current standards only offer vague guidance on how… 
A nature-inspired decision system for secure cyber network architecture
TLDR
A cyber decision support system that automatically generates security-optimized segmentation architectures for network environments subject to dynamically-changing cyber threats is proposed and demonstrated via a case study on a representative network environment under an evolving cyber attack.
Capturing the security effects of network segmentation via a continuous-time markov chain model
TLDR
This study examines an alternative method for evaluating segmentation architectures utilizing a continuous-time Markov chain to model changes in network state based on relevant network parameters such as vulnerability arrival rate, patch rate, etc.
A Trilevel Model for Segmentation of the Power Transmission Grid Cyber Network
TLDR
A novel trilevel programming model is developed to opti- mally segment a grid communication system, taking into account the actions of an information technolology (IT) administrator, attacker, and grid operator.
Deployment Decision Support for Mitigating Cyber Attacks on Wireless Sensor Networks
TLDR
Results show that routing protocol and sensor placement have substantial impact on the behavior and lifetime of WSN during cyber attack; analyzing this behavior aids in deciding on a sensor deployment.
Network Segmentation and Zero Trust Architectures
TLDR
While network segmentation shares similar goals with zero trust architecture, it has fundamental incompatibilities that prevent it from being a useful security enhancement within a ZTA.
Cyber-Physical Architecture for Automated Responses (CyPhAAR) Using SDN in Adversarial OT Environments
TLDR
This paper presents a formulation of a novel tradeoff analysis and its use in advancing a cyber-physical architecture for automated responses (CyPhAAR), which should evaluate the mitigation benefits of responses versus the physical affects that result.
Learning Security Strategies through Game Play and Optimal Stopping
TLDR
The interaction between an attacker and a defender is formulated as an optimal stopping game and let attack and defense strategies evolve through reinforcement learning and self-play to produce effective defender strategies for a practical IT infrastructure.
AUTOMATION OF NETWORK MICRO SEGMENTATION
TLDR
The Automation of Network Micro Segmentation Environment is used to configure the network and systems automatically and protects the sensitive data from hackers by allowing the data to be visible only to the selected users.
