Encryption of data at rest

Would the use of an OS with 128-bit encryption satisfy the encryption of data at rest?

    Encryption is one piece of the puzzle to address the data at rest requirement.

    In answer to your question, the NIST 800-111 guidance makes reference to the FIPS 197 document which does reference technologies that speak to the 128 bit reference you noted in your posting.

    However, this in and of itself would not satisfy the requirements because authentication is also a key aspect of the process that needs to be considered.
