Software signature

The software used on the Management Unit, HNC and Server Unit x86 is supplied in packages which are provided with a signature.

• The packages of the underlying base software Linux SLES 15 are signed by the vendor.

• The specific packages for the Management Unit, HNC and Server Unit x86 are signed by Fujitsu.

During installation the signature is used to check whether the status of a package is unaltered, i.e. corresponds to the production status.

If the signature check fails, installation of the package is rejected.
