Bulgaria takes special measures to protect computer networks
"The cyber attacks are scary," Borissov said at the annual meeting of the heads of diplomatic missions of the country abroad.
World practice showed that there were no impenetrable networks, Borissov said.
Borissov said he even met with hackers, and they told him that "in practice it is hard to protect our networks."
Meanwhile, the protection cost enormous money, he said.
Now, the State Agency for National Security (SANS) is dealing with this issue, Borissov said without announcing details.
In the autumn of 2015, websites of Bulgarian institutions such as the Ministry of Interior, SANS, parliament, president and Central Election Commission (CEC) have experienced difficulties as a result of a distributed denial-of-service (DDoS) attack.
During the first DDoS attack against CEC, which began on the day when Bulgaria held local elections and referendum on electronic voting, over 530 million requests were made to the Internet portal of CEC within ten hours, a quarter of them from IP addresses originating in Vietnam, Turkey and the United States, officials said then. ■
