CCI(s)

• CCI-001199 - Protects the confidentiality and/or integrity of organization-defined information at rest.
• CCI-002475 - Implement cryptographic mechanisms to prevent unauthorized modification of organization-defined information when at rest on organization-defined system components.
• CCI-002476 - Implement cryptographic mechanisms to prevent unauthorized disclosure of organization-defined information at rest on organization-defined system components.

Fix Recommendation

Configure Amazon Linux 2023 to protect the confidentiality and integrity of all information at rest.

Encrypting a partition in an already installed system is more difficult, because existing partitions will need to be resized and changed.

To encrypt an entire partition, dedicate a partition for encryption in the partition layout.

Check Contents

Verify Amazon Linux 2023 is configured so that all partitions are encrypted with the following command:

$ sudo blkid
/dev/xvda1: UUID="ed0acbe9-bd05-495e-a9ac-cb615b29327d" TYPE="crypto_LUKS"

Every persistent disk partition present must be of "Type" "crypto_LUKS".

If any partitions other than the boot partition, bios partition or pseudo file systems (such as /proc or /sys) are not type "crypto_LUKS", this is a finding.
