-- Lists all the security configurations visible to this account, providing
-- their creation dates and times, and their names. This call returns a
-- maximum of 50 clusters per call, but returns a marker to track the
-- paging of the cluster list across multiple ListSecurityConfigurations
-- calls.
--
-- This operation returns paginated results.
