Bold Coast Security Guidance

Staff should regularly be reminded not to post CUI to social media outlets or other public facing web services. For Level 3 compliance your policy and plans must be in place to manage CUI to include prohibited storage and use means. A data handling guide as a desktop reference works great to reinforce the requirements for where and how data can be stored, processed, and/or transmitted.
