How to build enterprise intranet security

Enterprise IntranetFor the risks faced by an enterprise's network security and to fully assess the risks that these risks may bring, they will be the primary problems that must be addressed during the implementation of security construction and the basis and basis for formulating security policies. So what security risks do enterprises have? What value can Enterprise Intranet security products bring to enterprises? Huang Kai, R & D Director of Yixin technology, learned about the information, users, and systems involved in Intranet security:

I. Information: security of confidential internal documents

About of business-related information in an enterprise will exist in the form of electronic documents. These internal information often involves trade secrets, or even the key core technology of the enterprise. The confidentiality requirements are high, once leaked, it is very likely to cause huge economic losses to enterprises.

1. A dedicated File Server may exist in the enterprise to store various types of documents. In the absence of effective management, any intranet user can access the documents and disseminate internal files or even confidential information at will, causing significant losses to the enterprise. Therefore, enterprises need to encrypt documents and set role-based user permission management.

IP-guard uses high-intensity transparent encryption technology to protect confidential information, so that files are automatically encrypted and protected after the user creates a new one. Encrypted Files cannot be decrypted and applied even if they are illegally transmitted to the outside of the enterprise. In addition, different internal document access control permissions can be set based on different departments and levels to establish a complete confidentiality system.

2. Enterprises may lack effective control over mobile storage devices. Anyone can copy and transfer electronic documents using their USB flash drives, MP3, and mobile hard drives, the risk of document leakage is greatly increased. If you completely disable the use of USB flash drive mobile devices, it will cause inconvenience to normal file transmission within the enterprise. Therefore, enterprises need to maximize information security while enjoying the convenience brought by mobile storage devices.

IP-guard can resolve the application conflicts between mobile storage devices in the organization. Its core is to control the permissions of external computer devices, including USB, Bluetooth, and optical storage devices, the classification standardizes and encrypts the use of mobile storage devices on the Internet. This is supplemented by a comprehensive mobile storage audit, and ultimately achieves both the portability and security of Mobile storage devices.

3. Enterprise Employees often use network-based programs such as QQ, fetion, MSN, and email for their work needs. These programs all have file transmission functions. If they are not restricted, it is highly risky to intentionally or unintentionally disclose files. Therefore, enterprises should effectively manage and control email and instant messaging tools.

IP-guard can manage the permissions for sending documents externally. Restrict outgoing mails from documents that exceed the specified size or contain the specified keywords, and even prohibit outgoing mails. This prevents important documents from being leaked through instant messaging tools. At the same time, the user's chat content and email content are fully recorded, so that managers can understand whether the user intentionally or unintentionally discloses important company information during the conversation.

Ii. Users: User desktop behavior Specification

In addition to confidential information within an enterprise, the efficiency of employees is crucial to the development of the enterprise. The popularity of the network undoubtedly improves the working conditions of employees and the overall efficiency of enterprises. However, some employees in an enterprise may indulge in online or desktop games and neglect their full-time work, seriously affecting enterprise development.

1. Some users may have irregular desktop behaviors, such as stock trading during work hours, browsing irrelevant news, online games, watching online movies, and listening to music, which are very inefficient, at the same time, P2P behaviors such as BT downloading, online videos, and thunder applications still exist, leading to frequent congestion of the company's bandwidth and the failure of normal network services. Enterprises must properly control and audit Internet access behaviors.

IP-guard can filter out all work-independent applications, and block the running of games, stock trading, media playback, instant messaging, BT, and other programs within a time period or around the clock. At the same time, it can also restrict the use of P2P software to help enterprises rationally allocate bandwidth resources and ensure stable network. In addition, IP-guard also provides a statistical table of user applications and web browsing conditions, allowing managers to clearly understand users' desktop behaviors.

2. Rich website resources not only bring useful information, but also contain pornographic and reactionary websites and their applications, improper Internet access behaviors of employees may lead to illegal download of viruses and Trojans into the enterprise. IP-guard can filter websites that are yellow, violent, or maliciously spreading viruses to ensure that users use webpages within compliance and legal scope, neither access or download, nor upload or spread any content containing pornographic violence.

Iii. System: system maintenance and Asset Management

The normal operation of IT systems is essential for enterprises to develop healthily. Due to the expansion of the company's scale and strength, the company's office locations may be distributed across different floors or even different regions, resulting in a large number of computer systems scattered, the company's internal asset statistics work is very cumbersome.

Computer systems are an essential part of an enterprise. Maintaining the normal operation of the system is the daily work of the IT administrator. Due to the lack of appropriate management tools, the enterprise often maintains hundreds of thousands of computer systems, it also makes the limited IT management personnel no longer flexible in the daily maintenance of the system, and the risk of system vulnerabilities continues to rise.

In this case, the system administrator can view the application, network connection, process, system information, and other basic information and running status of the Client Computer in real time through the IP-guard console, in a single console, You can grasp the running information of computers in the entire network. At the same time, it can also assist the Administrator to analyze the system running status and promptly solve system exceptions to prevent system faults. In addition, the system administrator can directly remotely control and operate on any computer on the IP-guard console, and can perform operations on remote computers in need to achieve Remote Desktop Access and two-way file transmission.

2. Many enterprises have large numbers of soft, hard, and non-IT assets. Traditional asset maintenance and management methods are cumbersome and time-consuming. After manual statistics are completed, information must be manually entered. When the data is counted or entered in half, the system adds new assets and the work is often interrupted. Once and again, IT managers will inevitably become confused, and tedious procedures will become so simple. Therefore, enterprises urgently need a simple method to count internal assets.

IP-guard automatically searches for and integrates IT asset information of client computers in the enterprise network, records hardware models in a centralized manner, saves manpower statistics, and automatically counts changes to hardware and software assets, provides a clear list of software and hardware Asset changes, allowing the system administrator to learn about asset changes through the console and keep up-to-date and most accurate asset information. It not only reduces the workload of the system administrator, but also avoids the loss and occupation of assets.

It can be seen that enterprises only carry out enterprise intranet construction from three aspects: protecting information asset security, standardizing user behavior, conducting effective system maintenance, and asset management, at the same time, combined with the necessary management systems and education and training systems, we can build a secure, efficient, and healthy Intranet for enterprises to help them grow and develop more rapidly!
