Prevent activesync brute force attacks

Hello,

 

 

we set up microsoft activesync with mobile devices. Everything is working fine, but i see an issue with the possibility of brute force attacksagainst the active directory authenrication. I found an irule to handle this, but with this irule the authentication is checked with every get / post request.

 

 

I´m wondering, it this ins´t possible with the anomaly detection module / brute force attack prevention, but I don´t know how to implement this for activesync.

 

 

Does perhaps someone know how to implement this, or has someone does this already?
