Hi, thanks for the example. Please let me improve it a bit:

• I've notice you have a typo in the second REGEX - a backslash instead of dot: select\*from should be select.*from
• I would make the filter case insensitive by adding (?i) prefix (documentation)
• if somebody want to add this filter via Plesk interface, he should add ignoreregex = string, otherwise plesk doesn't show the filter when you add a jail (I've spent like an hour to find it out).

So in my case, to use it with Plesk, the filter looks like this:

[Definition]
failregex = (?i)^<HOST> .*UNION%%20SELECT%%20CHAR.*HTTP
        (?i)^<HOST> .*select.*from.*HTTP
        (?i)^<HOST> .*select%%20name_const.*HTTP

ignoreregex =
