Network Security: Blocking Intranet security vulnerabilities to create a secure and stable network for Enterprises

Recently, a large Chinese shipbuilding company experienced a shocking network security incident. Because the computer system of the shipyard stores a large amount of important design data, one day, the system suddenly reported that a computer terminal was illegally copying the important file data, through the tracking of the Intranet audit system, network administrators immediately lock the computer that Copies files and the username of the login system, so that they can immediately stop the illegal behavior before important files are passed out, this avoids unnecessary economic losses.

In fact, similar Intranet security events occur in many enterprises. However, not every enterprise can avoid losses due to different levels of Intranet security. According to a survey, more than 85% of security threats come from within the enterprise, 16% of which come from unauthorized access within the enterprise, and 40% from leakage of electronic files, intranet security is a major concern for enterprise network security.

To ensure network security, firewall, anti-virus software, IPS, and other products have long been widely deployed by enterprise users. However, these products are usually virtual in the face of Intranet security threats, because "Internal Sorrow" is better than "external troubles", enterprises need not only strong boundary security, but also stable Intranet security.

So, are corporate CIOs well aware of Intranet security, how well they are deployed, and what else needs to be improved, what are the development trends of Intranet security in terms of product technology.

Over half of enterprises pay attention to Intranet Security

Network security threats emerge one after another, and network security problems are everywhere. However, there are always priorities. Which of the following areas of security issues must be solved by enterprise users? According to the survey, "Intranet Security" occupies the first place in 54.9%. Second, 25.7% of users choose Internet security, 10.6% choose terminal security, and 8.8% choose Web security.

Apparently, more than half of the users have set "Intranet Security" as the first issue to be solved. At the same time, this also shows that the user's awareness of the importance of Intranet security has reached a considerable level.

Huang Yi, Consultant of the Product Project Department of Beijing Unicom Network Technology Co., Ltd., made it clear that Intranet security management is often more important than internet security management, the leakage of confidential information and intrusion of business systems are often caused by unauthorized internal access and the proliferation of Trojans. Therefore, it is imperative to ensure Intranet security.

As an expert in the field of Intranet security construction, Wan Jun, manager of the strategic marketing department of Beijing dingpu Technology Co., Ltd., told reporters that the concept of enterprise security defense has been more limited to conventional network management-level firewalls), network border vulnerability scanning, security audit, anti-virus, IDS, and other aspects, the main security facilities are mostly concentrated in the machine room, network entrance. It should be said that, under the close monitoring of these security devices, security threats from outside the network have been significantly mitigated. However, with the continuous development of enterprise informatization, security threats from inside the network are gradually highlighted, and the internal security problems of the network become the industry consensus.

In this regard, we can confirm the current security details of enterprise users. In the question "which security details are important to your company currently", 83.2% of users choose virus detection and removal, 69.0% choose database security, and 46.9% choose network device security, 31.9% of users choose patch upgrade management, 31.0% of users choose website O & M security, 27.4% of users choose identity authentication, and 22.1% of users choose information encryption. As you can see, whether it is common virus detection or removal, identity authentication or information encryption, users are quite concerned about this.
