Smart gateway status analysis where smart gateway security is reflected

With the development of the Internet of Things, the security of wireless LANs is not only related to personal and family information security, but also a key area related to personal safety and property security. To achieve the security of the wireless LAN, it mainly depends on the core of the home area network - intelligent gateway.

Domestic gateway standards and status

In China, due to the large number of existing home network standards and the lack of uniform standards, it has brought difficulties to interoperability between devices of different home network protocols.

The competition among home network standards has led home gateways and home appliance manufacturers to find it difficult to choose an agreement as their own product standard. The lack of such unified protocol standards on the market has led downstream equipment manufacturers to produce equipment according to different interface standards and protocols. It has become very difficult to interconnect and interoperate between different devices. In turn, as manufacturers, manufacturers have headaches due to specific installation problems caused by the lack of equipment. Therefore, the standards for gateways, network protocols, and devices urgently need to be unified. This is one of the bottlenecks encountered by the smart home manufacturers' offline products.

The main gateway needs to be compatible with the home network standard protocol. The difficulty lies in how the home gateway realizes the conversion of the two protocols, so that the user can manage and control the two different standard protocol devices through the home gateway on the Internet.

The target devices in the home gateway system are divided into two categories: one is a device that has been transformed according to the original protocol, and the other is a device that supports a home network standard protocol, and the two devices communicate with the gateway according to their respective protocols. When the devices based on the two protocols and the web pages respectively perform data interaction, the functions of the gateway are different.

Smart Gateway Security

Whether to open the unnecessary remote login and management service port, such as telnet, ssh and so on. The opening of these ports is like opening a door to all kinds of viruses and hackers on the internet. Once the login password of these services is broken, hackers can freely log on to this gateway to intercept and steal user data. . You can even control the smart devices connected to this gateway.

There is no authentication and authorization mechanism for intelligent service remote management, which gives the possibility of hacker disguise management on internet.

The weakness of the gateway firewall function does not protect the gateway LAN internal devices with the enterprise firewall. Make LAN users have the risk of being attacked.

The execution permission of the system's third-party program must be shut down. A lot of virus attacks are implemented by searching for a router that can execute third-party scripts. As a zombie client, these zombie devices are used to attack the Internet.

The intelligent gateway is not only the control center of the smart device, but also the security performance of the smart device. The smart device manufacturers need to work hard to improve the security of their products and prevent the occurrence of large-scale attacks.
