Wu Jiangxing, academician of the Chinese Academy of Engineering, called for the construction of Internet 'border guards' to cope with the current network security situation.

Following recent developments, cyberspace has gradually developed into the 'fifth battlefield' after the land, sea, air and outer space, according to Wu Jiangxing, who is also a computer and network technology specialist.

At present, other countries across the world are already building their own network warfare units. In 2010, the U.S. Army Cyber Command was established, including four units and about 1,000 personnel. Other countries such as Russia, Israel, South Korea and India have also launched their network warfare forces.

But at the moment China has no such unit. In other words, China's cyberspace is effectively undefended. As a result, hackers can easily gain access to China and the country is generally plagued with spam, said Wu Xingjiang.

China has just begun research on the protection of national IT facilities. Compared to the "Cyber Storm" series of exercises the U.S. has held in recent years, China's research is far removed from the massive U.S. nationwide action, both in scale and in maturity.

Wu Jiangxing said China must cultivate the concept of network border defense, and develop and innovate technology to give China more ways and means to safeguard network order and cyberspace, along with a greater range of equipment.
