The SecuriDex was a directory of the Rebel Alliance where the Task Force on Alliance Security stored information about threats to their movement.
All the members of the Granse Confederacy had entries on the SecuriDex, particularly Lu'daal-ud. His had an addendum stating that, if any agents or operatives thought they were up to the task of capturing him, they were to contact their Task Force on Alliance Security for their proposal to be discussed.
