  • Respond to concerns and vulnerabilities raised by IGTF members and relying parties, by assessing risk and setting time and deadlines for response and action from the IGTF membership. This may include contacting individual CA operators and posting advisories to the igtf-general email list as needed.
  • Perform periodic audits of member CA contact addresses and other issues.
  • Periodically report to the IGTF membership on RAT activities (i.e., newsletter posts to the igtf-general email list and presentations at TAGPMA, EUGridPMA, APGridPMA, and IGTF All Hands meetings).
  • Maintain active RAT membership, including multiple representatives from each regional PMA (TAGPMA, EUGridPMA, APGridPMA) and keep the igtf-rat email list(s) and twiki pages up-to-date.


IGTF RAT Response Flowchart

The IGTF RAT operates by consensus. To react quickly and effectively, the group must have the ability to quickly reach consensus. We take the Apache Voting Process as a guide. Specifically, consensus is reached if there are three positive votes and no negative votes. Any official action requires that we reach consensus in this manner.

The IGTF RAT contacts CA operators via the email address in the .info file of the IGTF distribution. IGTF members are expected to monitor this address. The RAT expects responses from IGTF members within one business day. The RAT conducts tests of the CA email addresses twice per year.

To contact all IGTF CA operators, take the latest IGTF distribution and run

grep -h "email =" *.info | cut -c 9- | sort -u | perl -n -e '{ chomp; print "$_, " }' | sed 's/, $//g'

to get a list of addresses. Note the use of BCC or subjects including "please reply" is discouraged because it causes messages to be bounced or marked as spam.

For very urgent issues, the IGTF RAT may also post to igtf-general:

  IGTF CA operators:

  The IGTF RAT sent an urgent message to your registered email address.
  Please check your email and respond promptly.
  Contact if you did not receive the message.
