At present, new technologies such as cloud computing, big data, Internet of Things, artificial intelligence, and smart devices have been widely accepted and applied by "Internet" companies. On the other hand, the application of these new technologies has made "Internet" companies face unprecedented cyber security challenges. Recently, Tencent Security Joint Lab, China Electronics Technology Standardization Research Institute, Tencent Network Space Research Center jointly released the "Internet" Enterprise Network Security Ecological Research Report (hereinafter referred to as "Report"), indicating that many enterprises still lack the necessary network. Safety management system and related measures. Experts said that the current domestic network security market is still in its infancy, but with the passage of the Cyber ​​Security Law, it is expected to open a market of 100 billion in the future.
The "Report" shows that mobile Internet security issues are increasing, and personal information leakage has occurred. From 2005 to 2015, the number of malicious programs has soared from 52 to 1.477 million, of which malicious deduction attacks are particularly serious; one is to steal core data. The purpose of the advanced and persistent attack mode APT attack becomes the biggest threat to the information security of industrial control systems. In all APT attacks, key manufacturing accounts for 33%, energy sector accounts for 16%, and becomes the hardest hit; cloud services face trust. Crisis, cloud security issues are highlighted. Once an attacker discovers and exploits the security vulnerabilities of the cloud platform itself, it may lead to serious large-scale information disclosure incidents; security vulnerabilities remain serious, and software vulnerabilities become the focus. According to CNNVD statistics of China's national information security vulnerability database, 7754 new vulnerabilities were added in 2015, of which 5142 new application software vulnerabilities, accounting for 2/3 of the total, and application software vulnerabilities have become the main security threat of the “Internetâ€.
Statistics from relevant institutions show that the average loss of domestic large and medium-sized enterprises in the year due to information security incidents reached 2.4 million US dollars. And the annual computer and cybercrime losses are more than $445 billion.
An Outdoor CPE (Customer Premises Equipment) is a client device used in outdoor environments, typically for wireless network connectivity. It is a device used to transmit Internet signals from a service provider to the user's location.
Outdoor CPE is commonly used to provide broadband access services, especially in remote areas or places without traditional wired network coverage. It can transmit an Internet connection via wireless signals to the building or area where the user is located. Outdoor CPE is typically a highly protected and durable device designed to handle harsh weather conditions in an outdoor environment.
Outdoor Cpes typically include the following main components:
1. Antenna: Outdoor CPE is usually equipped with a high-gain antenna for receiving and sending wireless signals. These antennas can be designed for different frequency bands and wireless standards.
2. Wireless module: Outdoor CPE usually includes a wireless module to handle the transmission and reception of wireless signals. This module usually supports different wireless standards such as Wi-Fi, LTE, 4G, etc.
3. Router function: Outdoor CPE usually has the function of a router, which can distribute the Internet connection to the device where the user is. It can provide IP address allocation, port forwarding, network security and other functions in the local area network.
4. Power supply and battery: Since Outdoor CPE is usually used in outdoor environments, it usually requires a reliable power supply. Some Outdoor Cpes are also equipped with batteries to provide continuous Internet connectivity in the event of a power outage.
The main features and advantages of Outdoor CPE are as follows:
1. High-speed broadband access: Outdoor CPE can provide high-speed broadband access services through wireless signals, so that users can enjoy high-speed Internet connections in places without traditional wired network coverage.
2. Flexibility: Since Outdoor CPE is a wireless connection, it can be used in different locations and environments. Users can place the Outdoor CPE in the best position as needed for optimal signal coverage and performance.
3. Simple installation: Outdoor CPE usually has a simple installation process, and users only need to place the device outdoors and make some basic Settings to start using the Internet connection.
4. Strong anti-interference ability: Outdoor CPE usually has strong anti-interference ability and can provide stable Internet connection under harsh environmental conditions. It can cope with various sources of interference, such as electromagnetic interference, weather conditions and so on.
5. High reliability: Outdoor CPE usually has a high degree of reliability and durability, and can be operated for a long time in a variety of outdoor environments. It usually has waterproof, dustproof, lightning-proof and other functions to cope with different weather conditions.
Outdoor CPE is widely used in a variety of scenarios, especially in rural areas, mountains, islands and other places without traditional cable network coverage. It can provide high-speed broadband access services to residents and enterprises in these areas, helping them to enjoy the convenience of the Internet.
In summary, the Outdoor CPE is a client device for outdoor environments to provide high-speed broadband access services via wireless signals. It is highly reliable, flexible and anti-jamming, and can provide a stable Internet connection in a variety of outdoor environments. It plays an important role in providing broadband access services, especially in places without traditional wired network coverage.
