DBU ISPF Security utility
You can secure products against unauthorized updates.
When you implement security, only authorized users can use the ISPF interface to update product components (for example, PDX entries). If you do not implement security, any user who has access to the online panels can update product components. Only updates are restricted; online display is not restricted. You must have ISPF to use these security measures.
The DBU Security facility has two components: the security file and the security module. You should use the same security file and module for all products from the DBU tape.
