Container-based encryption provides a more fine-grained approach to the encryption of data and information including encrypting selected data structures such as files, records, or fields. <\/p>\n<p>Further Discussion<br \/>\nEnsure CUI is encrypted on all mobile devices and mobile computing platforms that process, store, or transmit CUI including smartphones, tablets, and e-readers.<br \/>\nBecause the use of cryptography in this requirement is to protect the confidentiality of CUI, the cryptography used must meet the criteria specified in requirement SC.L2-3.13.11.<br \/>\nThis requirement, AC.L2-3.1.19, specifies that CUI be encrypted on mobile devices and extends three other CUI protection requirements (MP.L2-3.8.1, MP.L2-3.8.2, and SC.L2-3.13.16):<\/p>\n<ul>\n<li>MP.L2-3.8.1 requires that media containing CUI be protected.<\/li>\n<li>MP.L2-3.8.2 limits access to CUI to authorized users.<\/li>\n<li>Finally, SC.L2-3.13.16 requires confidentiality of CUI at rest.<\/li>\n<\/ul>\n<p>This requirement, AC.L2-3.1.19, also leverages SC.L2-3.13.11, which specifies that the algorithms used must be FIPS-validated cryptography, and SC.L2-3.13.10, which specifies that any cryptographic keys in use must be protected.[\/et_pb_testimonial][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[et_pb_section fb_built=&#8221;1&#8243;
