What do red list and white list mean?

1. In order to avoid sending spam messages to the leaders of relevant departments, operators have blocked the mobile phone numbers of some "important people" by technical means to prevent them from receiving spam messages like ordinary users.

2. After the leaders of the major provinces and cities listed in the "red list" enter the red list, the operator will notify the agents by phone that they are not allowed to sell or send advertising messages to them.

White list:

The concept of 1. whitelist corresponds to "blacklist".

2. 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 rapidity are greatly improved.

3. Expand its meaning by one step, so that any application with blacklist function will have whitelist function corresponding to it.

Extended data:

Working principle:

1. Whitelisting technology enables enterprises to approve which processes are allowed to run in a specific system by identifying whether processes or files in the system have approved attributes, public process names, file names, publisher names and digital signatures.

2. Some vendors' products only include executable files, while others also include scripts and macros, and can block a wider range of files. Among them, an increasingly popular whitelisting method is called "application control", which focuses on managing the behavior of endpoint applications.

As we all know, whitelisting was once a criticized technology. Whitelisting has always been regarded as difficult to deploy and time-consuming to manage, which makes it difficult for enterprises to deal with employees who want to deploy their chosen applications. In recent years, the whitelist product has made great progress, which is better combined with the existing terminal security technology, eliminates the obstacles of deployment and management, and provides automatic approval for users who want to install applications quickly.

4. At present, most products also provide this function, that is, using a system as a benchmark model to generate their own internal white list database, or providing templates to set acceptable benchmarks, or supporting compliance with standards such as PCI DSS or SOX.
