Network security is a continuous process of attack and defense confrontation. To do a good job in network security, first of all, we should have a thorough and comprehensive understanding of various forms of network threats. Next, I will sort out the causes of network security problems for you. You can also visit this for more
1. Security vulnerabilities emerge endlessly
Security vulnerabilities generally refer to some problems arising in various stages of the information system life cycle (planning, construction, operation, etc.), which will affect the security (confidentiality, integrity, availability, etc.) of the system. With the development of big data, cloud computing, 5G, artificial intelligence and other technologies, data exchange is becoming more and more frequent, which leads to the blurring of network boundaries and the increasing number of vulnerabilities. There is a kind of zero day vulnerability with great harm in the security vulnerabilities, which refers to the vulnerabilities that are unknown to the software manufacturer and the public at the time of discovery and have no corresponding patches. Due to the small scope of proliferation and no corresponding protective measures, such vulnerabilities have high confidentiality and success rate when used, and are used by attackers to obtain powerful weapons under illegal control.
When attackers invade websites, steal business files, launch advanced attacks, and spread blackmail viruses, they often use security vulnerabilities as a breakthrough. With the ability to dig and utilize security vulnerabilities, attackers can get through the network tunnel, so that each attack target can become a network node and be permanently controlled. People engaged in network attacks do not need very strong technical skills, because the use of tools is simple and provides a set of scripts to guide how to attack. The network attacks launched by using security vulnerabilities have been industrialized, forming a huge “network black industry”, which poses a huge threat to the normal operation of enterprises.

Diversified network attack scenarios
New technologies promote the digitalization process of enterprises, inject new momentum into the transformation and upgrading of enterprises, but also bring new dangers to enterprises. The expansion of network attack has enriched the attack scene of hackers. According to the prediction of the Global Association of Mobile Communication Systems (GSMA), in 2025, the number of Internet of Things devices in the world will exceed 25 billion, and hundreds of millions of terminals and devices will access the Internet, which will increase the network security risk and diversify the network attack scenarios.
Large transnational hacker attacks, attacks against key infrastructure and Internet of Things equipment, data privacy leaks, and rampant blackmail viruses will cause huge damage to the network, not only causing serious impact on personal and corporate security, but also causing great economic losses, and even threatening national security.
3. Weak foundation for security construction
Information technology is changing with each passing day, and the informatization level of security management is constantly improving. However, in the process of information system construction of domestic enterprises, long-term absence of security, online system with problems, bare metal operation and other phenomena are common. Security and information construction still lacks top-level design, and the original management business flow and information flow are difficult to achieve seamless integration. For example, many industrial protocols, equipment and systems did not take into account the security in complex network environments at the beginning of design. The system has a long life cycle, few upgrades and maintenance, and there are potential security risks.
In addition, at the beginning of the design, the Internet mainly considered the transmission of information, and basically did not consider security issues. Due to the sharing and openness of the Internet, there is a congenital deficiency in online information security (the TCP/IP on which it depends lacks the corresponding security mechanism), so it is not adaptive in terms of security, reliability, quality of service, bandwidth and convenience. Enterprise security construction is often driven by compliance, and the phenomenon of focusing on construction, ignoring operation and maintenance is widespread.
