A filtering rule that includes one or more members in a set. For example, you can use allow list rules to tell a forwarder which files to consume when monitoring directories, or you can use allow list rules with the deployment server to explicitly select deployment clients.
You can combine allow list rules with deny list rules, which specify which members of a set to exclude, to achieve precise filtering. Deny list rules override allow list rules.
The term "allow list" replaces the term "whitelist". Both terms refer to the same functionality.
