How to prohibit foreign equipment from accessing intranet and extranet of enterprise?

Modern office, each enterprise will establish its own internal LAN, and set up a server to store and share the day-to-day work of the various types of data required, many employees will also share some of their own computer data, so that other users of the local area network access and use, this way is to save data delivery time, Improve the efficiency of everyone, it can be said, very convenient. However, the resulting information security, network security issues are gradually exposed, we have to pay attention to.

1, enterprises and foreign personnel to carry notebooks, mobile phones, tablets, etc., access to the enterprise LAN, can arbitrarily access the local area network share resources, including business secrets or important documents, once the malicious modification, copy, delete, the consequences of unimaginable, will make the enterprise suffered huge losses.

2, these foreign equipment may carry virus, Trojan and so on, access enterprise intranet, very easy to spread to the intranet of other computers, and the server has a significant impact, leading to damage or leakage of important data, disastrous consequences.

3, foreign equipment access to the enterprise LAN, if a large number of download files or online games, online video, online stock, etc., will seriously affect the speed, resulting in other computers can not normal access to the Internet, seriously affect the normal work of the staff order.

4, foreign equipment access to the enterprise LAN, arbitrarily modify the IP address or MAC address is also very common, if there is an IP conflict, will lead to the normal work. At the same time, modify the IP address or MAC address, also make some computers can exceed the Internet, evade network monitoring, and even to steal the company's important data or confidential information, is indeed a major network security risks.

Therefore, the enterprise network management personnel must to foreign computers, mobile phones, tablets and other equipment to carry out comprehensive, real-time, effective security management and monitoring, in order to protect the safety of business secrets, to ensure the stability and smooth internal network. So, is there any software specifically designed to manage this?

Through to netizens for help, small set to know the trend to software companies have a software in this respect, the name is "trend to network access control system", the software installation and operation is very simple, only to install on any one computer on the LAN can be.

First select the corresponding network card, click "Start Monitoring", the system will automatically scan all computers on the LAN, first displayed in the blacklist, and then we need to allow the Internet to move the computer to the white list, or all selected, all moved to the whitelist (white list that allows the Internet computer). If the foreign computer, mobile phone or flat-panel access to the LAN, you must first authorized by the Administrator to access, but also can directly check the "automatic isolation of foreign computers/mobile/flat", then foreign devices can not connect the enterprise intranet. If illegal practices are found, they can be either manually isolated or quarantined automatically. In addition, it can restrict its access to the intranet or access to the extranet. As shown in the figure:

So how do you prevent users from modifying IP or MAC addresses? Simply check the interface of "white list IP address changes automatically quarantine", "White list MAC address change automatic isolation" can be. Once discovered that the local area network computer modifies the IP address or modifies the MAC address to automatically isolate it, after the isolation cannot access the intranet and the outside net. The system automatically cancels quarantine only if it is changed back to its original IP address or MAC address.

This software not only can standardize the enterprise LAN management, restrict the foreign computer random access to corporate confidential documents, to prevent the release of important data, but also to protect against viruses, Trojans, especially the defense of worm viruses, defense of shock waves virus, against network storm attacks and other hacker attacks, but also can detect some hacker software intranet Record the dangerous host, send the alert information to the network administrator, so that the network administrator can locate the attacking source quickly and protect the intranet security. In addition, by prohibiting users from modifying IP and MAC addresses, users can also be prevented from using unauthorized Internet access to engage in illegal behavior, thus escaping network regulation. In short, this software can help the enterprise network management staff to solve a lot of headaches, simple operation, functional and practical, it is worth a try.
