Program overview
Information security, simply put, teaches you how to protect the "door locks" and "safes" in the digital world. It's neither pure programming nor pure management, but a combination of both—you need to understand how hackers attack (e.g., SQL injection, phishing emails) and how to set rules (e.g., employee password policies, data classification systems). Core courses include: cryptography (encryption and decryption), network attack and defense, Security Operations Center (SOC) management, data privacy and compliance (e.g., China's Data Security Law), and enterprise security architecture design. If you have clear logic, enjoy problem-solving, and are interested in "offense-defense confrontation," this major is a great fit. Many Chinese universities (e.g., Xidian University, Beijing University of Posts and Telecommunications) have strong hands-on labs in this field, even allowing direct participation in real enterprise security projects—a valuable resource for international students.
