Research on Cross Network and Cross Domain Network Security Protection System in Universities
In university network environments,characterized by large-scale networks,numerous users,and frequent information exchanges,network security risks have become more complex and diverse.To address these challenges,universities need to establish cross-network and cross-domain cybersecurity systems to ensure the smooth operation of teaching,research,and administrative activities.This paper analyzes the current state of cross-network and cross-domain cybersecurity in universities to understand the threats faced.Based on a comprehensive understanding of these threats,it designs a cybersecurity system that addresses complex and varied security challenges.First,it identi-fies the key security needs and potential threats within university networks.Then,it applies various key technologies such as SSL/TLS encryption,data classification and encryption,virtual private network(VPN),multi-factor authenti-cation(MFA),single sign-on(SSO),etc.,to construct an integrated security protection system covering boundary de-fense,internal monitoring,identity authentication,data protection,and security event response.Through these mea-sures,universities can not only enhance their level of cybersecurity but also ensure that network and data security are maintained throughout digital transformation and information construction processes,providing a solid foundation for higher education and scientific research.
