IP blocking in nginx after a certain number of 404 requests (in a row or per hour)

Question

Nginx

Actually, there is a certain bunch of pictures with an incremental ID, I want to complicate the life of stupid brute-forcers. Is there any way to do this with nginx only?

Answer 1

There is a good module
limit_conn_status 404
There are a lot of samples in Google according to the directive.
