D.1 Preconfigured Certificate Risk Disclaimer
The Huawei-issued certificates preconfigured on Huawei devices during
manufacturing are mandatory identity credentials for Huawei devices. The
disclaimer statements for using the certificates are as follows:
1. Preconfigured Huawei-issued certificates are used only in the deployment
phase, for establishing initial security channels between devices and the
customer's network. Huawei does not promise or guarantee the security of
preconfigured certificates.
2. The customer shall bear consequences of all security risks and incidents arising
from using preconfigured Huawei-issued certificates as service certificates.
3. A preconfigured Huawei-issued certificate is valid from the manufacturing date
until May 2041.
4. Services using a preconfigured Huawei-issued certificate will be interrupted
when the certificate expires.
5. It is recommended that customers deploy a PKI system to issue certificates for
devices and software on the live network and manage the lifecycle of the
certificates. To ensure security, certificates with short validity periods are
recommended.
