Brief Analysis of Enterprise Intranet security construction status

With the development of information technology, informatization plays an increasingly important supporting role in enterprises' production and operation activities. The popularization of Enterprise LAN, the wide application of office automation, and the implementation of various application systems such as ERP, MES, and production automation within the enterprise bring great convenience to enterprise activities, it also brings many security risks, such as virus spreading, leakage of confidential enterprise information, loss of production business data, and network abuse. At this time, the enterprise's protection measures are mainly firewall-represented network boundary protection. Once the firewall is crossed, it will cause great damage and risks to the enterprise's internal network.

This is mostly due to the limited computer knowledge of most users in the enterprise, lack of awareness of information security, lack of protection awareness, and lack of technical measures for enterprise network prevention, therefore, it is difficult to effectively monitor and prevent single point threat outbreaks in the LAN. Relying on a single border firewall and anti-virus software, it cannot cope with viruses and other information security threats. Only by protecting each client can it effectively prevent virus intrusion, information leakage, and worms, network abuse and other problems. Therefore, Enterprise Intranet security management becomes increasingly important.

Overview of Intranet Security and Management

The concept of Intranet security: Generally, we are limited by the network boundaries of the enterprise lan. The enterprise network is divided into two parts: Intranet and external network. Therefore, Intranet security refers to the information security of the enterprise's internal LAN. Specifically, it refers to the comprehensive management of information security of networks within the enterprise LAN firewall, which further includes the comprehensive management of LAN terminals. Due to the rapid development and changes of IT technology, new technologies and new security threats are constantly emerging. Therefore, the concept of Intranet security is constantly changing from beginning to end.

Intranet security status quo

With the development of enterprise information construction, more than 80% of the materials and data of enterprise production and operation are stored in the form of electronic documents and data. This information includes the company's core production technology, business cost information, daily production data and other aspects of the data, high reliability, confidentiality requirements, if the data is lost or leaked, this will cause unpredictable consequences to the production and operation activities of enterprises.

The popularization of Enterprise LAN lays the foundation for enterprises to improve employees' work efficiency and enhance their overall competitive strength. However, irregular desktop behaviors of employees, such as stock trading during work hours, online games, and online movies, seriously affect work efficiency. At the same time, BT downloads, online videos, thunder applications, and other behaviors cause blockages on the Enterprise LAN and affect normal business development. Illegal or unhealthy website browsing may lead to illegal downloads of viruses and Trojans into the enterprise LAN, which seriously harms the security of the enterprise network.

External personnel cannot be effectively managed. The company cooperates with the staff of the outsourcing unit to come to the factory for communication. Because the computer equipment of the relevant personnel cannot be checked in time, it is easy for the computer equipment to bring viruses and Trojans into the internal network of the enterprise. At the same time, the lack of external personnel monitoring will also cause leakage of internal information of the enterprise.

Due to the development of enterprises and scattered office locations, a large number of computer systems are distributed, making asset statistics within the enterprise very cumbersome. IT is the daily work of the IT department to maintain the normal operation of computer systems. However, due to the lack of appropriate management tools, the maintenance of hundreds of thousands of computer systems within the enterprise is usually performed, it also enables limited IT management personnel to invest a limited amount of time in unlimited system maintenance work.

With the continuous development and progress of information technology, the management of Intranet security is also evolving. From initial asset management, patch distribution, access control, device encryption, behavior auditing, data leakage prevention, and transparent encryption, with the development of technology and the concept of Intranet security, the construction of Intranet security is becoming more and more comprehensive and mature.

Currently, Intranet security management has entered the era of overall leakage prevention. Access Control and encryption cannot solve all problems, and pure behavior audit has no significance. We only carry out comprehensive and multi-angle design on information security from a global perspective of enterprise information security management, and make overall planning and unified arrangements, comprehensive integration of access control, network monitoring, security audit, permission management, transparent encryption, and other means, according to different security levels in the enterprise LAN, different confidentiality levels, deploy a tiered protection system with different levels and different levels of strength to organically combine management, technology, audit, and personnel to build a three-dimensional overall security network within the enterprise, in order to achieve real Intranet security.
