With the amount of SIP hacking on the increase this is a pretty good webinar for those people that are running Asterisk Boxes,

We have seen a increase in SIP hacking attempts across NZ at the moment, it comes and goes in cycles and you would have possibly seen a few News Items about it as well ,

Whilst we take care of the certified devices on VFX, security on Open VFX and Asterisk devices is the users' responsibilty so here is a nice little webinar sent to me by my support team to share with you.

Please Asterisk users take your security seriously as getting burned can be costly for you and us and niether of us want that Cry.

If in doubt seek advice

i think we've seen some 2000 SIP requests bounce off our firewall in the last two weeks. Varying source IP's and varying CLI's. Well worth a second look, even if you think you're safe..

I've seen numerous attacks looking back at logs as well.

If you're running trixbox the fail2ban script is in later distributions. You should be running this as a bare minimum. Extensions locked down to local IP ranges is also a very good idea!
