A good way to defend against brute force attacks is to allow a certain number of login attempts, say three, and after that start delaying or blocking further attempts. Let's see how we can use ModSecurity to accomplish this.

If your login verification page is situated at yoursite.com/login, then the following rules will keep track of the number of login attempts by users:

#
# Block further login attempts after 3 failed attempts
#
<LocationMatch ^/login>
# Initalize IP collection with user's IP address
SecAction "initcol:ip=%{REMOTE_ADDR},pass,nolog"
