Chatham rules

Many ISACs apply Chatham rules to establish anonymity around verbally shared information of particular sensitivity. This implies that the shared information within the group can be used by the members in the desired way, as long as the identity of the originator or any connection to the members is kept secret. Chatham rules are to be decided and established by the ISAC facilitator or the members themselves in advance. In the beginning phases of the ISAC, having the Chatham rules signed by each member facilitates some neccessary formality around the rules.
