An Improved Verification Method Based on Asynchronous Verification

With the rapid development of Industrial Internet of Things (IIoT) technology, its applications have permeated various aspects of life and multiple industry sectors, significantly enhancing convenience. However, the large-scale deployment of HoT devices has also triggered numerous security issues, especially in enterprise-level applications. Although some current methods have alleviated these problems to a certain extent, they still face many challenges in practical applications. This paper proposes an improved solution based on asynchronous verification methods, integrating Risk Assessment Based on Security Baseline, Business Security Mechanisms, and Global Access Control List into the algorithms of the Verification Server. The aim of this method is to enhance internal traffic security by rejecting access from high-risk hosts, ensuring minimal API access authorization, and enforcing security policies, thereby avoiding the rapid depletion of resources at the Verification Server due to excessive malicious failed requests.
