Need a tool to monitor apache logs for suspicious requests and ban users via htaccess

Question

Do you know any tool that monitors apache logs for suspicious actions (for example, several blocks by mod_security from one IP) and after it blocks this IP using .htaccess?

Answer 1

You can take a look at fail2ban. Not sure if there is an action to ban via .htaccess, but that can be added in -- if you don't want to ban via iptables.
