Five Facts About Application
Usage on Enterprise Networks
in China
Application Usage and Risk Report
December 2011

Average number of social networking
applications per organization?
A total of 48 different social networking applications were
found in 94% of the 18 participating organizations with an
average of 7 found on each network.

Which application is used more heavily?
Based on the percentage of social networking bandwidth
consumed in the 18 participating organizations, Renren
consumed 34%. Facebook and Twitter consumed 1% and
0% respectively.

Local social networking applications dominate. Facebook,
Twitter and their “active” uses struggle for their share of
bandwidth.

Average number of browser-based
filesharing applications per organization?
A total of 30 different browser-based filesharing
applications were found in 89% of the participating
organizations with an average of 8 in each.

Browser-based filesharing use cases: work or
entertainment. Both uses have a common set of business
and security risks that organizations must address.

The number of applications
using Port 80 (tcp/80) only?
The number of applications that ONLY use Port 80 is 135 or
26% of the 535 applications found in the participating
organizations.

Percentage of total bandwidth consumed
by applications not using tcp/80?
49% of the total bandwidth is being consumed by 161 (30%
of 535) applications that DO NOT USE port 80 at all. Ever.

Port 80 only security is shortsighted. The common
perception is that Port 80 (tcp/80) is where all the traffic and all
the problems are. A port 80 emphasis is an absolute
requirement; but too much focus is shortsighted.
