had to Update from 1.6 to 2.5, antihack?

[agidi1]

Hello, we had a trusty Elastix 1.6 working but the PSU decided to quit on us.
So i downloaded 2.5 and set it up.

But i could not find the Anti-hack module i had seen before in the add ons and cant find how on earth to instal secast on it.

This is a small box and i use a couple of remote SIP ext.

please advice on anti-hack or secast install, i cant find anything.
