Hi

I had an attack yesterday where a single IP address generated a large number of 404 errors (around 20/second). There was 776 unique URLs targeted.

The 404 shield is a great feature but I wondered if there was a way to automatically block an address if a certain number of 404 errors are generated (possibly within a certain timeframe), without needing to specify the URLs?

Kind regards
Dan

Hello,

there isn't such feature since a plugin in Joomla is not the correct tool for the job.
In order to block an URL after too many attempts, we need to track them down, writing in the database. This means that there are 2 database operations (read + write) for each URL.
In order to block such URL, the server has to load a massive amount of resources (CPU, memory, database connection, load Joomla core, load all system plugins and THEN we can decide to block it or no).
The best tool to protect yourself from too many queries is to setup a CDN for your site: in this way the traffic is handled by the CDN, blocking attackers.
