Guiyang, capital city of Southwest China's Guizhou province, is actively building a security framework to protect big data.

After the ransomware virus Wannacry hit computers across the world, cybersecurity has become a hot topic.

In order to resist hackers, the city has planned a '1+1+3+N' top-level design, Guiyang's vice mayor Xu Hao said at a news conference on Tuesday.

Guiyang has achieved the first '1' to become a big data security pilot city.

The second '1' is about establishing a security-testing site to examine different big data products, technologies and services.

The '3' means the city will create a big data security situation reaction center, supervision center and innovation center.

According to Xu, the big data security situation reaction center is ready for the 2017 China International Big Data Expo to be held in Guiyang on Thursday.

The 'N' means numerous big data security and cyberspace security platforms for different areas and industries will be built in Guiyang in the future.

The heads of Guiyang's government bodies will take charge of their institutions' cyberspace security management from June this year, Xu said.

Since 2015, a big data expo has been held in Guiyang each year.
