The logs contain a lot of requests from unknown ip addresses to non-existent pages, which gives them a 404 error. Is it possible to block automaticly such ip addresses with frequent requests?
On the Traffic Inspector settings page, there is a setting called Error Shielding Mode. Set it to Maximum compatibility to enable monitoring and blocking of IP addresses that generate an excessive number of 404 requests. When set to Maximum security, WP Cerber will monitor and block other types of erroneous requests as well.
