Based on the current situation and problems of Intranet security, the technology alone cannot guarantee the competitiveness, or even the actual protection effect. These core causes of Intranet security problems can be solved only when the security management methods and security product management capabilities reach a certain level. In the face of increasingly complex application environments, administrator
