Journal Security 
Journal security is a component of task security that uses application member access rights to enforce your journal creation and posting policy.
Features
Journal security involves defining users that can administer (AdminJournal), create (CreateJournal), post (PostJournal), or unpost (UnpostJournal) journal entries. With AdminJournal rights, a user can create templates and clear journal tables (see Journal Template Creation and Journal Table Clearing).
You set up journal security by choosing Security in the Admin console, creating a task profile called Journals without selecting any checkboxes, then selecting one or more journal tasks and one or more teams or users.
Note
If you give users create access but not write access to a data region, they cannot create journal entries for that data region.
