There are several realities that typically fall outside of the approved enterprise communications mechanisms. These applications can enhance business responsiveness and performance – but, conversely – introduce inbound risks such as malware and vulnerability exploits, and outbound risks such as data loss and inadvertent sharing of private or proprietary data.
Palo Alto Networks identified several patterns related to users’ applications to collaborate with others. These applications were pervasive among these participating organizations, and can be summarized as “saying, sharing and socializing applications.” In fact, these applications present are in up to 96% of the participating organizations and consume nearly one-quarter of the overall bandwidth.
Saying: unmonitored, unchecked, and very risky
Saying applications, including webmail and instant messaging applications, are still being used in a largely unmonitored and uncontrolled manner, which introduces significant inbound and outbound risks. All of these saying applications either hop ports or use fixed ports that are not TCP/80 or TCP/443, which means that these applications cannot be easily monitored to control the related business and security risks. Furthermore, 60% of the saying applications discovered are capable of transferring files, thus opening organizations up to data leakage and the delivery of malware via attachments.
Sharing: users have found a better way to move and broadcast data
Since 2008, browser-based file-sharing applications have steadily grown in popularity to the point where they are now used more frequently than P2P or FTP. Now seen in 96% of organizations, these applications simplify file sharing but can also be broadcast-oriented (similar to P2P) in their distribution model. Using RapidShare, MegaUpload, or MediaFire, users can now upload their content and allow it to be indexed by one of the many affiliated search engines.
Socializing: when at work, Facebookers are voyeurs
Traffic patterns of Facebook may contradict certain assumptions about its use in the workplace. The bulk of the traffic (88%) is users watching Facebook pages. The risks that voyeurism represent include a potential loss of productivity and the possibility of malware introduction by clicking on a link within someone’s “wall.”
Comparatively speaking, usage of Facebook apps (including popular games such as FarmVille) only represents 5% of Facebook traffic. Facebook posting represents an even smaller 1.4% of the traffic, yet the small amount of use should not minimize the risks in terms of what users are saying about work-related subjects such as current projects, travel plans and company status.
Cloud-based computing: adoption driven by users and IT?
Results indicate that IT organizations may be moving beyond debating the pros and cons of enterprise-class, cloud-based applications to actual deployment. The traffic usage patterns for select Microsoft and Google applications indicate both top-down and bottom-up adoption, especially in the last months.
For example, enterprise versions of Google Docs and Gmail were found in 30% of the 723 participating organizations. In other words, the high use of “free” versions of the Google applications by the end-user may be forcing IT to consider these tools as licensed and fully supported alternatives—or replacements—for existing tools. As more tech-savvy users enter the workforce, their work patterns and requests for more application alternatives will likely accelerate the adoption of a wider range of enterprise-class applications.
