- Social, video, and filesharing are not the top threat sources. While 339 social networking, video, and filesharing applications represent 20 percent of network bandwidth use, they account for less than 1 percent of threat logs.
- Exploits continue to target enterprises' most valued assets via commonly used business applications. Of the 1,395 applications studied, 9 business critical applications were responsible for 82 percent of all exploit logs.
- Malware hides inside custom applications. Custom or unknown applications are the leading type of traffic associated with malware communications, accounting for 55 percent of malware logs, yet they are consuming less than 2 percent of network bandwidth.
- SSL is used as both a security mechanism and a masking agent. 356 applications use SSL in some way. SSL by itself represented 5 percent of all bandwidth and the 6th highest volume of malware logs. HTTP proxy, used both as a security component and to evade controls, exhibited the 7th highest volume of malware logs.
