Wireless Data Shot: Security and the Enterprise (cont'd)
Most Common Types of Security Used in the Enterprise
As with previous questions relating to connectivity/data access, responses to the various types of security in
enterprise usage were cross-tabulated by developer type; corporate enterprise or independent. Overall, the
disparities between corporate and independent wireless developers are reasonably similar with the exception
of a few cases.

Independent developers are far more likely to use SSL/TLS secure channel encryption, which is supported by
the vast portion of this segment which chose \"Encryption of data before it is sent.\"
Wireless developers who identified themselves within the corporate enterprise sub-group we most likely to
use \"Digital Signatures,\" \"VPN,\" and \"Public Key Infrastructure\" mechanisms in their solution designs.
How Many Tiers in Enterprise Wireless Apps?
When our survey group was divided into corporate enterprise and independent segments, we cross-tabulated
the preferred tiered design choices used in wireless applications architectures. Overall, the divergence was
not large, except in a few areas.
Corporate enterprise developers prefer three-tied designs over any other type, by a margin of 12 points—quite
a noticeable split. This can be directly linked to the long-term and successful push from various enterprise
platforms—corporate developers are very comfortable with this architectural design paradigm.

The largest disparity is the answers in the \"Don't Know\" category. Nearly three times as many independent
wireless software developers do not know how many tiers will be in use. This is not due to a lack of technical
expertise, but is mainly attributable to the consultative, client-driven nature their application designs.
