Discussion Text
Changes to any software components can have significant effects on the overall security of Ubuntu 24.04 LTS. This requirement ensures the software has not been tampered with and that it has been provided by a trusted vendor.
Accordingly, patches, service packs, device drivers, or operating system components must be signed with a certificate recognized and approved by the organization.
Verifying the authenticity of the software prior to installation validates the integrity of the patch or upgrade received from a vendor. This ensures the software has not been tampered with and that it has been provided by a trusted vendor. Self-signed certificates are disallowed by this requirement. Ubuntu 24.04 LTS will not have to verify the software again. This requirement does not mandate DoW certificates for this purpose; however, the certificate used to verify the software must be from an approved CA.
