Can Apple phones be whitelisted?

Apple's mobile phone has no whitelist function.

I. Basic concepts

The concept of white list corresponds to "blacklist". After the blacklist is enabled, users (or IP addresses, IP packets, emails, viruses, etc. ) the blacklist cannot be passed. If the white list is set, users (or IP addresses, IP packets, emails, etc. ) will be given priority in the white list and will not be rejected as spam, so the security and speed are greatly improved. Extend its meaning one step further, then any application with blacklist function will have whitelist function corresponding to it.

Two. introduce

The concept of white list corresponds to "blacklist".

For example:

In the computer system, many softwares apply the black-and-white list rule, such as operating system, firewall, antivirus software, e-mail system, application software and so on. And almost all the control aspects have applied the black-and-white list rule. After the blacklist is enabled, users (or IP addresses, IP packets, emails, viruses, etc. ) the blacklist cannot be passed.

If the white list is set, users (or IP addresses, IP packets, emails, etc. ) will be given priority in the white list and will not be rejected as spam, so the security and speed are greatly improved.

Extend its meaning one step further, then any application with blacklist function will have whitelist function corresponding to it.

For example, in the operating system, if a user's number is blacklisted, he may not be able to enjoy a certain service or all services, and the users in the white list may not be restricted by the ordinary user rules in the system.
