Conclusion first: no
As a senior network security engineer, my point of view is that network security is a long-term continuous field, not a career that is easily eliminated. This may change as technology advances and new threats emerge, but as professionals in the cybersecurity field, we need to learn and adapt to new technologies and continually enhance our skills and knowledge.
The field of network security is a very broad field, including but not limited to network defense, penetration testing, security analysis, and emergency response. With the development of technology, new threats and attack methods continue to emerge, so network security engineers need to constantly learn and update knowledge, and master new technologies and methods to protect network security.
Second, cybersecurity is a growing industry with ever-increasing demands. Whether it's a business, government agency, or individual, cybersecurity engineers are needed to keep their networks safe. In the first-tier cities at the forefront of social and economic development, the cyber security industry is particularly popular.
Network security involves key information and data assets, and ensuring information security is of great significance to enterprises and governments. As an important force in ensuring information security, network security engineers have an important position and development prospects.
Conclusion: Network security engineers do need to constantly learn and update their skills, but they are not easy to be eliminated. On the contrary, due to the ever-increasing demand for network security in society, there is still a broad space for development in the field of network security.

The government's emphasis on network security is also increasing. With the promulgation and implementation of the "Network Security Law", the entire network security industry will have greater development opportunities. In terms of policies, policies, regulations and support measures will also be used to provide support for the cultivation of network security talents, technological innovation, industrial development, and business operations.
4. Opportunities for innovation and development
Cybersecurity is an active, innovative field. Technical innovation and development such as offensive and defensive drills, malicious code analysis, vulnerability mining, and security big data mining will bring new opportunities for the development of the security industry. At the same time, with the development of the Internet, some new application scenarios, such as the application of blockchain technology, network security in smart home and other fields, will also provide a large number of new opportunities for network security talents.
Network Security Career Orientation
Network Security Engineer
Network security engineer is the core profession in the field of network security. They need to have knowledge of network infrastructure, computer systems and software, as well as familiarity with basic encryption techniques, vulnerability discovery, security awareness education and response to vulnerabilities. Knowledge in these areas will be applied to defend against and respond to various information security threats.
security manager
Security managers need to formulate security policies and policies, assess security risks and formulate countermeasures, conduct security audits and compliance checks, etc. They should have a certain understanding of the entire life cycle of network security, and be able to comprehensively analyze risks and formulate specific protection measures.
security analyst
Security analysts discover potential network security issues by analyzing logs and data generated in the network, and conduct security risk assessment and alarm response. They need to have the ability to analyze various data such as vulnerabilities and attacks.
penetration tester
Penetration testers are an important network security profession. They are mainly responsible for simulating attacks on enterprises and organizations in order to discover the loopholes of enterprises, thereby improving the network security defense capabilities of enterprises. Penetration testing works across the Internet, mobile devices, web applications, and internal network structures.
Security operation and maintenance personnel
Security operation and maintenance personnel are responsible for managing and maintaining the network security system to ensure the security of the enterprise's information system and data. Including the responsibilities of managing security devices, maintaining systems, responding to emergencies, and detecting attacks.
Data Security Engineer
With the advent of the big data era, the demand for data security engineers is increasing. They need to protect, process and store data securely, ensuring data integrity and confidentiality. Work in the field of data security involves data privacy protection, big data security management, data mining, and vulnerability analysis.
Mobile Security Engineer
With the popularization of mobile Internet, mobile security has obviously become a new security risk. Mobile Security Engineer
Mainly responsible for the protection of APP, system security, mobile device security and other aspects. Mobile security engineers need to understand the knowledge of mobile device system structure, APP development characteristics and vulnerability characteristics, and also need to be familiar with mobile security attack techniques and defense methods. Their main task is to design and implement security strategies for various mobile devices and APPs, and to ensure that mobile devices and APPs will not be attacked or leak data during use.
Anti-fraud engineer
Anti-fraud engineers need to master artificial intelligence, machine learning and other technical means, and analyze user behavior and other data to conduct risk assessment and early warning, tracking and monitoring of fraudulent behavior. They are mainly responsible for responding to malicious network attacks such as network fraud, fraud, and devil programs, especially in industries such as finance, e-commerce, and games.
How to get started with network security
Network security is an extremely complex field that requires not only basic knowledge of computers, but also a deep understanding of the field of network security. Here are the basics you need to know about cybersecurity and how to get started:
