The TF-CSIRT Steering Committee coordinates the activities of the Task Force. It is comprised of the TF-CSIRT Chair, the TF-CSIRT Secretary (ex-officio) and six elected representatives.

The TF-CSIRT Chair is elected every two years. The other elected representatives also serve two year terms, but the terms are staggered so that two representatives are elected each year. Elections are normally held during TF-CSIRT meetings in September. If you are interested in participating as an SC member, we have prepared some information that might be useful as to the commitment involved.


The Steering Committee has the following responsibilities:

  • Coordinating the activities of TF-CSIRT and recommending courses of action where issues occur.
  • Making decisions on CSIRT accreditation and certification in accordance with the guidelines agreed by the TF-CSIRT membership.
  • Reviewing the performance of the Trusted Introducer service and making recommendations to modify or expand it.
  • Overseeing the development of the TRANSITS training curricula and course materials, monitoring tutoring standards, and registration of tutors.
  • Advising on future developments and strategic directions in computer security.
  • Providing input on meeting agendas.
