National Cyber and Information Security Agency (NCISA) has issued a WARNING against the use of both software and hardware of Huawei Technologies Co., Ltd., and ZTE Corporation. Use of these devices presents a security threat.

„Issue of this warning concludes our findings and those of our allies and security partners. The main issue is a legal and political environment of the People’s Republic of China, where aforementioned companies primarily operate. China’s laws, among other things, require private companies residing in China to cooperate with intelligence services, therefore introducing them into the key state systems might present a threat,” says the director of NCISA Dušan Navrátil.

Another reason NCISA has issued a warning is that the People’s Republic of China actively pursues its interests in the territory of the Czech Republic, including influence and espionage intelligence activities. This is exemplified in the annual reports of security services for 2017.

„According to the Act on Cyber Security, a warning means that system administrators in the critical information infrastructure, important information systems or essential service providers are obliged to acknowledge the threat and issue adequate measures. We do not differentiate between state-owned or privately owned systems. Our criterion is whether or not the intrusion of a specific system would have an impact on the functioning of the Czech Republic as a sovereign state,” says Dušan Navrátil.
