The document summarizes key findings from a Palo Alto Networks application usage and risk report on enterprise networks in Singapore: - On average, organizations had 16 social networking applications with Facebook consuming 67% of social networking bandwidth and Twitter consuming 7%. - Browser-based filesharing applications were found in 92% of organizations with an average of 18 applications per organization. - 28% of applications, or 217 applications, only used port 80 while 49% of total bandwidth was consumed by 29% of applications that did not use port 80 at all. - The report emphasizes that while port 80 is important, too much focus on it alone can be shortsighted given other applications using different ports.

1. Five Facts About Application
Usage on Enterprise Networks
in Singapore
Application Usage and Risk Report
December 2011

3. Average number of social networking
applications per organization?
A total of 64 different social networking applications were
found in 97% of the 65 participating organizations with an
average of 16 found on each network.

5. Which application is used more heavily?
Based on the percentage of social networking bandwidth
consumed, Facebook consumed 67% of the social
networking bandwidth. Twitter consumed a mere 7%.

6. Facebook is dominant in Singapore. Action oriented uses
(apps, games, posting, and plugin) are used more heavily in
Singapore than they are globally.

8. Average number of browser-based
filesharing applications per organization?
A total of 47 different browser-based filesharing
applications were found in 92% of the 65 participating
organizations with an average of 18 in each.

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

11. The number of applications
using Port 80 (tcp/80) only?
The number of applications that ONLY use Port 80 is 217 or
28% of the 775 applications found in the participating
organizations.

13. Percentage of total bandwidth consumed
by applications not using tcp/80?
49% of the total bandwidth is being consumed by 216 (29%
of 775) applications that DO NOT USE port 80 at all. Ever.

14. 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.
