[TYPO3-english] Preventing brute-force attacks in FE login form

[Claudio Strizzolo]

Hi all,
I am currently using Typo3 4.5.

Does someone have any hints about preventing brute-force attacks using 
Typo3 FE login form (felogin system extension)?

For instance: if a user supplies a wrong password several times in a 
certain time interval (let's say: 10 times in 2 minutes), don't let 
him/her trying again using the same username in the next 15 minutes. 
Basically I'd like to avoid brute-force attacks by automated tools.

Many thanks in advance,

Claudio
