Jakarta, INTI - Cybersecurity has become one of the most vital issues for nations across the globe. In the face of increasing international cyber attacks, China has positioned itself as a country with one of the most complex and robust cybersecurity defense systems. With the largest internet infrastructure in the world, and continuously evolving policies and technologies, how does China protect itself from the ever-growing sophistication of cyber threats?
This article will explore how China builds its formidable cybersecurity defenses, the strategies used to counter foreign attacks, and the innovations that make it one of the most advanced nations in the field of cybersecurity.
The Great Firewall: A Shield from the Outside World
One of the most controversial yet highly effective policies in China’s cybersecurity defense is the Great Firewall. This system acts as a barrier that blocks access to foreign websites and services deemed potentially threatening to national security. For instance, platforms like Google, Facebook, and Twitter are blocked in China, replaced by domestic platforms like Baidu, WeChat, and Alibaba.
By controlling internet traffic entering and leaving the country, China can monitor suspicious cyber activities and prevent attacks originating from abroad. Freedom House, in its report, labeled China as having the strictest internet policies in the world.
Quantum Encryption Technology: A Major Leap Toward Absolute Security
One of the most significant innovations developed by China to bolster its cybersecurity defense is Quantum Cryptography. This technology is seen as the future of data security, as it is nearly impossible to hack. In 2017, China launched the Micius satellite, the world’s first quantum encryption satellite. This satellite allows China to transmit encryption keys through light particles, which cannot be hacked without leaving traces.
This innovation places China as a leader in the global race toward stronger cybersecurity. Other nations, including the United States and the European Union, are also investing in quantum encryption technology, but China remains at the forefront.
International Cyber Attacks: An Ever-Present Threat
While China focuses on its cybersecurity defense, it is also involved in international cyber operations. According to a report from FireEye, China is suspected of having state-sponsored hacker groups that frequently conduct cyber espionage for economic and political purposes.
One of the most notorious groups is APT41, which cybersecurity researchers believe is affiliated with the Chinese government. APT41 has been accused of launching attacks against technology companies in the United States, Japan, and European nations.
