the FTP authorization rules

Explanation:
Use the FTP Request Filtering feature page to define the request filtering settings for your FTP site.
FTP request filtering is a security feature that allows Internet service providers (ISPs) and Application
service providers to restrict protocol and content behavior. For example, using the File Name
Extensions tab you can specify a list of file name extensions that are allowed or denied. Source:
