The given explanations are not exactly the one to answer the question. Those are only security types or ways. In BO, the security levels are applied to row level and column level. Both have been handled by the administrator in supervisor tool or in designer tool. These two levels of securities are used to restrict the data at row level or column level in case of a particular user or user group. Please explore Business Objects forum to get more information about row level security and column level security.
