Those activities are logged in the error log. just check the log file once for a while. Most time you don't need to any thing, as those are taken care of by server itself unless the attacker is not frustrated and keep doing that, then you can block them at firewall level.
We will add a option to send email notification when we further improve the anti-attack engine. With current engine, you may receive too many alerts when it happens.
If your sites got attacked a lot, and current litespeed can not feed off those attack very well, please send us more information about the attack, if you can figure out the pattern of the attack. :-)
