The Token Trust and Traceability Working group has been instantiated in the Summer of 2023 to answer security questions posed by the move from x509 to Tokens for AAI, problems faced by the WLCG and EGI communities.
This work encompasses a revisit to the successful work of the Traceability and Isolation WG, which concluded in 2019 with two principle findings[1][2], paraphrased as a need for:
simple, but regular tests of the experiment traceability capacities;
documentation e.g. at EGI level to help sites discover how to identify what they need.
