National CERT Department

National CERT was established in accordance with the Information Security Act of the Republic of Croatia and according to the Act CERT is a national body for prevention and protection from computer threats to the security of public information systems in the Republic of Croatia. One of its main tasks is to harmonize the treatment of security computer incidents in public information systems created in the Republic of Croatia or in other countries and organisations when connected with the Republic of Croatia.

According to the Ordinance on the Work of National CERT, the Department deals with incidents if one of the parties to the incident is in the Republic of Croatia (i.e. if it is in the .hr domain or in Croatian IP address space).

The work and organisation of National CERT should be aligned with the Information Security Act (Official Gazette 79/2007) and the requirements set forth in the Cybernetic Security Act on key services providers and digital service providers (Official Gazette 64/2018), which stipulates that the Croatian Legislation adopted Directive 2016/1148 of the European Parliament and of the Council of July 6th, 2016 on measures for a high level of security of network and information systems throughout the Union (the so-called NIS Directive – The Directive on Security of Network and Information Systems). The action of National CERT is largely determined by the National Cyber Security Strategy and its action plan.

National CERT service users are all users of public information systems and Internet users in the Republic of Croatia, including CARNET users and providers of hosting services and Internet access services (ISP). Users of National CERT service can be all Internet users in the Republic of Croatia, i.e. resident users, business entities, institutions, Internet access providers in the Republic of Croatia and other entities other than state administration bodies that are in charge of ZSIS CERT.

National CERT is organized into four services:

  • Incident Handling Service
  • Infrastructure Security Service
  • Security Awareness and Governance Advisory Service
  • Service Development and Maintenance Service

The Incident Handling Service works to mediate the resolution and processing of incidents as the first level of resolution, support and coordination. The service also works on the processing of aggregated data and the preparation of reports, as well as on raising awareness of cyber security.

The Service Development and Maintenance Service deals with the development of services and applications that we use when processing incidents, automating certain processes and facilitating the processing of incidents with various scripts. The largest project currently being implemented is the development of a national platform for the exchange of incidents (PIXI).

National CERT is implementing proactive and reactive measures within its activities. Proactive measures work before the incident and other events that could endanger the security of public information systems to prevent or mitigate potential damage. Reactive measures have an impact on incidents in the Republic of Croatia and other events that could endanger the computer security of public information systems in the Republic of Croatia.

Proactive measures implemented by National CERT are:

  • monitoring the situation in the field of computer security and publishing news from the field of Internet security
  • release computer-security recommendations on detected vulnerabilities
