Techniques for replicating changes to access control lists on investigative analysis data

Techniques for replicating changes to access control lists on investigative analysis data are disclosed. After a change is made in a database to an access control list (ACL) governing access to a secured component of a data object, an exporting nexus sends an ACL change network message to an importing nexus. The ACL change message includes information that importing nexus can use to apply the ACL change to the importing database. Applying the ACL change message includes using the information in the ACL change message to determine which change records for which secured components of the data object in the importing database the ACL change should be applied to. By doing so, user access to all change records in the importing database to which the ACL change is applied is governed by the new ACL, thereby preventing unauthorized access to the change records, including historical change records.
