If you want to become a network security engineer, GPT recommends that you need to master the following technologies:
1. Basic network knowledge: understand basic concepts such as network protocols, network topology, and subnetting.
2. Operating system knowledge: Familiar with the security configuration and vulnerabilities of common operating systems (such as Windows, Linux).
3. Database knowledge: Understand database security configuration and defense technologies.
4. Programming language: master at least one programming language, such as Python, C++ or Java, for writing automation scripts and developing security tools.
5. Principles of network security: Understand the principles and common attack methods of network attacks, such as DDoS, SQL injection, cross-site scripting attacks, etc.
6. Encryption algorithm: Familiar with common encryption algorithms, such as DES, AES, RSA, etc., and the principle of public key infrastructure (PKI).
7. Firewall and intrusion detection system: understand the principle and configuration of firewall and intrusion detection system.
8. Vulnerability assessment and penetration testing: Learn how to assess system vulnerabilities and conduct penetration testing to find and fix security vulnerabilities.
9. Security Incident Response: Learn how to identify and respond to security incidents, including incident analysis, forensics, and emergency response.
10. Security awareness and legal knowledge: Understand laws and regulations related to network security and privacy protection.
In addition, it is also very important to continuously learn and keep up with the latest technologies and threats in the field of network security. Participating in relevant training courses, passing certification exams (such as CISSP, CEH), and practical experience are also key to becoming a network security engineer.
