When a client uploads a file to a server, NSFOCUS WAF performs protection based on the file type. If the file type matches an illegal upload restriction policy, NSFOCUS WAF allows or blocks the upload based on the corresponding action specified in the policy, and logs the event. On the Illegal Upload Restriction page, customers can create, edit, delete, and duplicate illegal upload restriction policies.
Choose Security Management > Policy Management > Basic Protection > Illegal Upload Restriction, click Create in the upper-right corner, configure basic information and inspection information as required, and click OK.
