For a unified vision of the security of critical infrastructures and sensitive sites

In a joint project, partners of the SECEF consortium have defined the IDMEF V2 standard for detecting incidents on cyber and physical systems. The partners are CS Novidy’s from CS Group, IMS Network, CyberTest System, and Centrale Supelec. The project received support from the Région Ile de France and the Public Investment Bank of the French State.This new “Incident Detection Message Exchange Format” is an improvement of the IDMEF V1 format (RFC 4765), which CS GROUP has used for over a decade for security event supervision within its SIEM PRELUDE. Initially, it was specialized for detecting cyber intrusions and the new version extends to all incidents.

A new IDMEF V2 format has been submitted to the international standardization organization IETF (Internet Engineering Task Force) where the main Internet standards are defined (HTTP, SMTP, FTP, etc.). The SECEF consortium has opened a site,to collect external contributions for possible enrichment.

Thanks to the European H2020 7SHIELD research project (Grant Agreement n. 883284) for the protection of critical infrastructures such as the European ground segments (, the SECEF and 7SHIELD projects were able to jointly enrich the IDMEF V2 format. CS Novidy’s, then partner of the 7SHIELD project and Leader of the SECEF project, brought its IDMEF experience to the 7SHIELD project and reciprocally enabled the IDMEF V2 format of the SECEF project to benefit from the experimental feedback carried out on a large scale on the five pilots European countries (Belgium, Finland, Greece, Italy, Spain) of the 7SHIELD project.

Gabriele Giunta, ENGINEERING ING. INF. SPA (Italy), project coordinator and expert in security of critical infrastructure confirms that “The use of IDMEF in a specific UAF format to 7SHIELD was essential for our experiments. About thirty technical modules of our system architecture are able to communicate with each other thanks to this format, in a very effective and seamless way. We are looking forward to supporting a future standardization.”
