The UEM server must be configured to implement FIPS 140-2/140-3 mode for all server and agent encryption.

Without confidentiality protection mechanisms, unauthorized individuals may gain access to sensitive information via a remote access session. Remote access is access to DOD nonpublic information systems by an authorized user (or an information system) communicating through an external, nonorganization-controlled network. A block cipher mode is an algorithm that features the use of a symmetric key block cipher algorithm to provide an information service, such as confidentiality or authentication. AES is the FIPS-validated cipher block cryptographic algorithm approved for use in DOD. For an algorithm implementation to be listed on a FIPS 140-2/140-3 cryptographic module validation certificate as an approved security function, the algorithm implementation must meet all the requirements of FIPS 140-2/140-3 and must successfully complete the cryptographic algorithm validation process. Currently, NIST has approved the following confidentiality modes to be used with approved block ciphers in a series of special publications: ECB, CBC, OFB, CFB, CTR, XTS-AES, FF1, FF3, CCM, GCM, KW, KWP, and TKW. This requirement also applies to Zero Trust initiatives. Satisfies:FCS_COP.1.1(1), FTP_TRP.1.1(1) Reference:PP-MDM-414001

Verify FIPS 140-2/140-3 mode has been implemented on the UEM server for all server and agent encryption. If FIPS 140-2/140-3 mode has not been implemented on the UEM server for all server and agent encryption, this is a finding.

Configure the UEM server to implement FIPS 140-2/140-3 mode for all server and agent encryption.
