When & How to Report Security Incidents – ENISA releases new guidelines
The European Union Agency for Cybersecurity (ENISA) releases new guidelines to facilitate the reporting of security incidents by national telecom security authorities.
The guidelines published help national telecom security authorities in the reporting of significant incidents to ENISA and the European Commission under the European Electronic Communications Code (EECC).
These new guidelines replace the previous ones issued by ENISA on incident reporting under Article 13a of the EU Telecoms Framework Directive. This revised version takes into account the scope and the provisions of the EECC and provides non-binding technical guidance to national authorities supervising security in the electronic communications sector.
The following three types of incident reporting are provided for under article 40 of the EECC:
1. National incident reporting from providers to national security authorities;
2. Ad-hoc incident reporting between national security authorities and ENISA;
3. Annual summary reporting from national security authorities to the European Commission and ENISA.
The new guidelines focus firstly on the ad-hoc incident reporting between the security authorities and ENISA and secondly on the annual summary reporting. More specifically, the document includes information on how and when security authorities can report security incidents to ENISA, to the European Commission and to other security authorities.
The information provided considers the services and incidents within the scope of the EECC - incidents affecting confidentiality, availability, integrity and authenticity of networks and services. The thresholds needed for the annual reporting are also defined. These thresholds are both of a quantitative and of a qualitative nature.
The quantitative elements considered include the number of users affected and the duration of the incident. Qualitative information was also used, such as the geographical coverage of the incident and the impact on the economy, on society and on users.
The new guidelines also include an incident report template and draw the distinction between national and annual reporting.
This report was drafted by ENISA in close cooperation with the ECASEC expert group of national telecom security authorities.
