SecureLogix just released our 2013 Voice and Unified Communications State of Security Report. Rod Wallace and myself authored the report. The report covers the most significant voice and UC threats. the report describes the threats and why they have recently and continue to become more severe. The report is also unique in that it presents real-world data collected from several hundreds assessments and managed service engagements, using our technology, on enterprise voice and UC networks. We present trending data and santized attack examples for each threat.
