Global VoIP security threats - large scale validation based on independent honeynets
2015
2015 IFIP Networking Conference (IFIP Networking)
Preserved Fulltext
The results show similar attacker behavior, confirm previous assumptions about attacks and present new insights in large scale VoIP attacks, e.g., for toll fraud. ...
In order to effectively protect VoIP users from misuse, researchers use, e.g., honeynets to capture and analyze VoIP attacks occurring in the Internet. ...
SETUP, OPERATION AND STATISTICS OF THE INDEPENDENT HONEYNETS The honeynets use different architectures for trapping and analyzing VoIP attacks, because the honeynets were designed and implemented independently ...
