The title (written by the BBC) seems to be ambiguous. This is not about hardening US computer systems, this is about banning US companies from using Huawei 5G technology. The United States has been lobbying other countries to not use Chinese 5G technology for a while now, while it doesn't seem like there are currently any viable alternatives. This makes it a nation-wide ban.
