Managing risk in high assurance systems by optimizing topological resources

Abstract

We explore strategies for manipulating the topology of a network to promote increased and pragmatic high assurance systems. Topology matters to network threats and security, and the relative distance between nodes can impact the rate of dispersion of viruses, as well as access times in denial of service, probing, and insider threat attacks. We suggest methods to separate threatening and threatened nodes with enough hops to reduce and degrade risks. This work provides network analysts with an option to include other measures such as risk assessments to the construction and management of high assurance systems. We consider a scaled down model to demonstrate the proof of concept using artificial data. Specifically, we explore the efficacy of ring networks and the structure that occurs on k‐hop networks when there are a prime number of nodes. We introduce techniques for the randomization of network topologies to manage real‐time risk and provide a dynamic means to improve network security by increasing technical debt to a potential attacker.

Maintenance of Network Security in Hospital Information Construction Based on the Internet of Things

“…It can improve employee productivity, reduce operating costs, avoid duplication of work or errors, and give full play to the functions of the hospital information system. Effectively improve the quality of medical care and strengthen the communication between doctors and patients so as to obtain better treatment and care, but his research did not clearly propose how to specifically and effectively improve the quality of medical care [1]. Baykara and Das conducted a survey of ten hospitals, and the informatization construction funds of each hospital are related to the hospital's business income.…”
