Critical Information Infrastructure Protection

The recent years have seen a tendency for the economic systems of different countries and the society as a whole to increasingly rely on information systems. In handling their day-to-day errands more conveniently, citizens can take advantage of various e-services such as online banking, reporting electricity statements, declaring taxes in the e-tax system, using mobile parking, etc.

Our dependency on the proper functioning of IT solutions has increased remarkably. The failure of an information system can have a substantial impact on the functioning of commercial enterprises and/or state agencies, thus also affecting the way customers/citizens are able to use services. From a country's perspective, the proper functioning of vital services is of great importance.

The purpose of the critical information infrastructure protection (CIIP) is to maintain a trouble-free functioning of the country's essential information and communication systems under ordinary circumstances and to ensure their continuity on a minimum level during critical situations.

The Section of Critical Information Infrastructure Protection at the Estonian Information System’s Authority (RIA) mainly concentrates on questions related to the protection of such information systems that are needed for the proper functioning of vital services. The main task of the section is to arrange protection for the state’s critical public and private information systems on the national level.

On the national level, RIA arranges the protection of such public and private sector information systems that are relevant for the functioning of the state of Estonia. We mainly focus on the issues of protecting the information systems that ensure the functioning of vital services. Vital services are services necessary for organising the functioning of the society, healthcare, security and people’s economical and social well-being. Pursuant to the Emergency Act, there are 43 vital services in Estonia.

On the strategic level, the protection is handled in the field of CIIP, where data about the critical information infrastructure (CII) are collected and maintained. Additionally, risk analyses related to CII are prepared, the respective security measures are developed and the supervision for following the methods is initiated.

On the operative level, RIA’s subunit the Computer Emergency Response Team of Estonia (CERT) handles the protection of the information systems necessary for the provision of vital services.
