Thanks M,
I have security enable,
; output security messages to the file named "Security"
security => security
I see the file created in /var/log/asterisk/security but is empty, and
in /var/log/asterisk/messages I see the following:
[2015-12-03 06:52:32] NOTICE[19949] chan_sip.c: Failed to authenticate
device 100<sip:[email protected]>;tag=a121ab55
X.X.X.X is the IP of my Server, I don't know who is the attacker IP
unless I monitor for the server using the following command:
tcpdump -lni eth0 -f "udp port 5060"
Please advise.
Thanks,
Motty

The details of the source IP are available in the asterisk security
log (if you have that enabled) – but that particular attack hides its
address from the messages file.
It’s essential that you secure your PBX; there are options ranging
from free to commercial. Have a look at:

It’s easy to get a $20,000 phone bill, so take securing your PBX
seriously.

Hello, I continued to see this errors in the logs:
[2015-12-02 10:05:57] NOTICE[19949]: chan_sip.c:23277
handle_request_invite: Failed to authenticate device
100<sip:[email protected]> <mailto:sip:[email protected]>;tag=10cdeaf7
how do I guard against this kinds of attacks? Also, to get the IP
address from where this attack come from I use the following command
"tcpdump -lni eth0 -f "udp port 5060" is there an easy way to get the
attacker's IP?
Thanks,
Motty
