LAN access control system | Dashizhi network access control software

Prevent external computer access, prevent ARP attacks, detect mixed network cards, and prohibit proxy Internet access

Awarded: The first domestic LAN security software that focuses on preventing external computers from accessing the company's LAN, preventing ARP virus attacks, preventing network sniffing, and prohibiting proxy Internet access.

Software introduction:

 Dashizhi network access control system is a professional LAN security protection system launched by Dashizhi (Beijing) Software Engineering Co., Ltd. to effectively prevent external computers from accessing the company's LAN and effectively isolate LAN computers (forbid computers from accessing the Internet or accessing LAN servers to share files, or prohibiting computers from communicating with other computers on the LAN; it can also prohibit employees from bringing their own laptops, IP Ads, smartphones, etc. are connected to the company LAN through wired or wireless wifi), prohibiting computers from modifying IP and MAC addresses, detecting LAN promiscuous mode network cards, defending against LAN ARP attacks, detecting LAN proxy software, and prohibiting computer proxy access to the Internet. The core functions can provide effective solutions for LAN network security, standardized network management and commercial secret protection of enterprises and institutions.

The specific functions of this system are as follows:

1. It is forbidden for external computers (such as laptops) or mobile devices (such as tablets or mobile phones) to access the unit's LAN to access the Internet;

2. Prohibit external computers from accessing internal computer resources in the LAN or server shared files, and prohibit external computers from communicating with computers within the unit;

3. It is forbidden for computers within the unit to modify the IP address or MAC address to prevent IP address theft, IP conflict attacks, unauthorized access to the Internet or evasion of network monitoring;

4. Forbid computers in the unit's LAN to actively access external devices, and external devices cannot access internal devices to achieve two-way isolation;

5. Real-time detection of online or offline status of computers inside the LAN or external computers;

6. Break through all firewalls to isolate internal computers or external computers from accessing the Internet or accessing the internal LAN;

7. Detect network cards in promiscuous mode in the LAN to prevent LAN computers from running hacking software, sniffing software, packet capture software, etc.;

8. Defend against LAN ARP attacks, ARP spoofing, ARP virus attacks, ARP hijacking attacks, etc.;

9. It can scan LAN wireless routers in real time, ban intranet wireless routers, restrict the installation of wireless routers, or prohibit Internet access through wireless routers.

10. Based on the network filtering driver, it is forbidden for external devices to access internal computers or internal computers to actively access external devices.

11. Detect the software and hardware configuration of the client computer, remotely restart the client, close the client, etc.
