4. Policies

4.1 Types of Incidents and Level of Support

For statistical purposes, the incident reports are divided in the following categories:

  • Vulnerability
  • Malware
  • Scam
  • Data breach
  • Denial-of-Service attack
  • Phishing
  • IoT
  • APT
  • Disruption of service
  • Data leak
  • Spam
  • False positive

The automated bulk incident reporting system Autoreporter provides technical reports in a wide range of categories such as reporting a large number of varying types of bot malware (e.g. ZeuS, Conficker, ZeroAccess), web server break-ins, denial of service attacks and worm-like behavior.

The early-warning system HAVARO categorises the incidents in RED, yellow and green, based on the severity of the incident.

The vulnerability advisories produced by NCSC-FI are categorised based on the target type, exploit method, anticipated outcome and the existence of a supported fix or documented workaround.

4.2 Co-operation, Interaction and Disclosure of Information

NCSC-FI is governed by the Act on the Openness of Government Activities (621/1999 (External link)), according to which all Official documents must be public, unless specifically otherwise stated in the law. Exceptions to the opennes principle are detailed in

  • section 24 of the Act on the Openness of Government Activities
  • Government Decree on information security in central government (681/2010 (External link)) and
  • act on the international information security requirements (588/2004, not translated).

NCSC-FI has a legal mandate to receive, handle and share cyber security information, including telecommunications identification data that facilitates the investigation of network and information security incidents and threats.

4.3 Communication and Authentication
