Providing cyber security for the data was top-priority since the very beginning of the digitalization. Fault-tolerant data processing centers belonging to the Government of Moscow are used as a basis for countering attacks. So far, a data protection system has been built for the data center, which has made it possible to ensure the protection of the information systems located in the data center.
In 2018, we took measures to identify unauthorized access to the Moscow data storage and processing centers. During this year, more than 27,572  cyberattacks have been blocked. We are constantly improving our security system, conducting inspections and audits of security systems.
The correct functioning of the newly built information protection system has been confirmed by the positive results of certification tests for compliance with information security requirements and the issue of a certificate of conformity of the information facility with information security requirements.
As for our surveillance system, access to these cameras is also limited and controlled. In 2018, we developed an automated information system called Access Control System for Information Systems and Resources of the City of Moscow, which is designed to ensure safe, reliable identification and authentication of users when accessing the information systems of Moscow. The video retention period is about five to seven days. Within five days, any citizen can apply for data from video cameras. According to the statistics, 80 percent of users contact us within three days and a further 15 percent in the remaining two days.
