Research on access control model of conference system in small LAN environment

With the rapid development of information technology, conference systems become increasingly important in a variety of scenarios, but also bring security challenges. This paper defines the concept of access control, reviews the research progress of access control in the current literature, and analyzes the network characteristics, user group characteristics and security requirements of the conference system in the small LAN environment. On this basis, this paper designs the access control model of conference system in detail, including user permission management, access control policy, technical implementation scheme, and proposes the method of model effect evaluation. Through security evaluation, performance testing, flexibility testing, user satisfaction survey and other methods, we can fully understand the actual effect of the access control model, and make continuous improvement according to the evaluation results.
