Security Risk Analysis of Private Wireless Routing Equipment
February 10 12:08:59, 2024
(1) The original network boundary has been multiplied and destroyed
The wireless monitoring equipment inside the video surveillance network is so limited that the network boundary of the internal building should be directly radiated to the distance of 30 meters or more in the core of the building, which greatly expands and destroys the existing network boundary of the internal network. Attackers can use this WIFI channel to increase the risk of internal network attacks and intrusions.
(2) It is vulnerable to intrusion and has high security risks.
Although the private wireless router provides certain security measures, it is often unable to fully utilize the security protection capability of the routing device due to the user's security awareness and technical level, making the wireless routing device vulnerable to attack and cracking. Intruders can easily invade the internal network through wireless routing devices by means of cracking and deception in a distance of 30 meters or more, and easily perform damage to the internal network.
(3) It is difficult to monitor, and it is difficult for managers to discover the behavior of private devices.
For the network with HUB or HUB-like access, the supervision of private wireless routers is very difficult. It is difficult for managers to distinguish whether the devices that provide HUB access are legal or private. Is it wired or wireless. More difficult to supervise is the routing device accessed through NAT. Even if the administrator restricts the MAC and device port binding, an 802.1X-based access control system is established. Such devices can still be easily deceived. Access, the concealment and deception of such access makes it difficult for managers to find, let alone regulate. (Author: Li Hongmei Huang Xiaoping)
1. Compact structure: The pump body and impeller are designed in one piece, which makes the pump more compact, occupies a small area and is easy to install and maintain.
2. Corrosion resistance: The pump body and impeller are made of high-strength cast iron with special treatment on the surface, which has excellent corrosion resistance.
3. High efficiency and energy saving: The impeller is made of high quality wear-resistant material, which has the feature of high efficiency and energy saving and can greatly reduce energy consumption.
4. Safe and reliable: There are multiple protection measures during the operation of the pump, such as overload protection, overheating protection, etc., which ensure the safe and reliable operation of the pump.
5. Wide application: cast iron pumps are suitable for various industrial fields, such as petroleum, chemical, pharmaceutical, food, textile, etc., and can convey various liquid media.
