hello everyone. i am concerned about security to the PBX and i would like to discuss different fraud detection methods. Apart from making everything to secure the PBX (latest patches, iptables, firewalls, no outside users, strongs passwds,…) i would like to find out if there are any fraud detection techniques. As for my setup i do have a PBX running asterisk 11.4 and it has 3 sip trunks (over internet)

  • i use a CRON CDR database lookup every 10 minutes (it is a sort of a compromise period of time). The script checks for all tall and international calls for the last hour. The script has different thresholds for different territories.

    it works reliably but I think about more sophisticated algorithm to discover any fraud attempts (I want to analize the security log as well).

  • You could check out a company called pbxwall. They have a product that is more of a realtime fraud prevention. It is not free. We had a look at it and it looks like a pretty good product but budget did not allow us to get one. Pbxwall.com
