In response to stakeholder requests and to enhance the usability of the CUI Registry, ISOO recently updated the CUI Registry to reflect the banner markings that can be applied to the various categories of CUI. You can find this change on individual category pages, directly below the category name. This change should assist authorized personnel in the proper application of CUI Markings. ISOO has also developed a number of resources that should assist with the proper marking of CUI. The CUI Marking Handbook, training videos (Introduction to Marking & Marking Commingled Information), and the CUI Coversheet are great resources as you implement and begin marking CUI.
