Bold Coast Security Guidance

Labeling is second nature to larger organizations, but a new and occasionally challenging task for smaller organizations to stay on top of. To make it easiest for users, adopt as few labels as possible reflecting the data in your environment. A "CUI" label may be the easiest, but you may find that using red markings or red paint is a more graphic and easy to spot representation of the importance of the data. Remember to Include labeling requirements in your security training and on any data handling posters or signs you create.
