Hi, everyone, Last week, we kept working on the design of security prototype. we were writing our proposal about how to make authorization decision, store object permissions, access control granularity and design revocation mechanisms. For the hardening prototype, we are working on reducing the prototype attack surface by analyzing the inputs, removing threats and using fuzzing tools to discover weaknesses.
