The purpose of NCSC-FI’s CERT activities is to prevent information security incidents and to disseminate information on information security matters.

The duties of CERT-FI include:

    • solving information security violations and threats against network, communications and value-added services;
    • gathering information on such incidents;
    • disseminating information on information security matters.

    The objective of CERT-FI's activities is to:

      • ensure that public communications networks and communications services function safely and properly;
      • safeguard functions that are vital to society.

      Our CERT services provide help in information security matters. In addition to general information about information security, we can also provide help in the technical investigation of severe information security violations.

      Our alerts, advisories, vulnerability reports, guidelines and other notices are available on our website under ‘NCSC News’ (External link), as RSS feeds , via mailing lists and in Yle’s teletext service (External link), on page 863

      We welcome contacts for example in the following situations:

      • attacks and attempted attacks against the infrastructure of the internet, such as name services and backbone networks
      • automatic and widely-spread attacks and attempted attacks against websites
      • severe attacks and attempted attacks against telecommunications networks
      • detection and attempted use of new forms of attack
      • information security violations and attempted violations against information systems of private persons, companies, organisations or the public administration.
