'Consumer' grade communications electronics, e.g. routers, modems, phones are (deliberate by design) unsecured devices.

We have mentioned that Microsoft's BitLocker encryption has vulnerabilities;

Now the lawmakers of the United States have put through law that forbids people in government using hardware manufactured by Huawei or ZTE as shown in article within screenshot;

Just one aspect of secure communications is the use of https:// in web addresses as opposed to the not so secure http://.

In order to be assured of some sort of security, login links for quite some time contain the address https://, however ZTE have deliberately omitted the https protocol in favour of the more vulnerable http to gain access as administrator to their hardware.

In the above illustration the web browser warns that the connection is not secure i.e http://

The company TP-Link also has this not secure mode of login to their routers.

We therefore do not recommend the purchase or use of Huawei, TP-Link or ZTE.

Optus sells Huawei modems to Australia's 'consumers'.

Optus and Virgin also sell ZTE pocket wifi devices.
