The findings are based on analysis of traffic data collected from 5,500 network assessments and billions of threat logs over a 12-month span. The report provides the industry’s most detailed assessment of the relationship between advanced cyber threats and the applications running on enterprise networks worldwide.
The Application Usage And Threat Report provides an analysis of applications and their link to cyber threats within the enterprise. The report summarises network traffic assessments performed worldwide in more than 5,500 organisations where 2,100 applications, 16,000 unique threats and billions of threat logs were observed.
Key takeaways:
- Common sharing applications such as e-mail, social media, and video remain favored vehicles for delivering attacks but are often the start of multi-phased attacks rather than the focus of threat activity.
- 99 percent of all malware logs were generated by a single threat using UDP; attackers also use applications like FTP, RDP, SSL, and NetBIOS to mask their activities.
- 34 percent of applications observed can use SSL encryption; many network administrators are unaware of what applications on their networks use unpatched versions of OpenSSL, which can leave them exposed to vulnerabilities such as Heartbleed.
In addition to the findings, the report includes actionable intelligence that security teams can use to better protect their networks, such as:
- Deploy a balanced safe enablement policy for common sharing applications – key to the success of this recommendation is documentation of the policies, education of users, and periodically updating the policy.
- Effectively control unknown traffic – every network has unknown traffic: small in volume, averaging only 10 percent of bandwidth we observed, but high in risk. Controlling unknown UDP/TCP will quickly eliminate a significant volume of malware.
- Determine and selectively decrypt applications that use SSL – selective decryption, in conjunction with enablement policies outlined above, can help businesses uncover and eliminate potential hiding places for cyber threats.
