Cyber attacks using the VoIP protocol Session Initiation Protocol (SIP) have been growing in 2016, accounting for over 51 percent of the Voice over Internet Protocol (VoIP) security event activity analysed in the last 12 months, according to a new report from IBM’s Security Intelligence group.
“SIP is one of the most commonly used application layer protocols in VoIP technology, so it’s not surprising that it’s the most targeted. In fact, we found that there has been an upward trend in attacks targeting the SIP protocol, with the most notable uptick occurring in the second half of 2016,” states the IBM Security Intelligence group.
The second most targeted protocol, Cisco’s proprietary Skinny Client Control Protocol (SCCP), accounted for just over 48 percent of detected security events during the same time period.
