*Who controls the encryption keys*

Figure 24 examines the issue of control over encryption keys in the 
cloud environment for both encryption of data
at rest and encryption of data at the application level. Thirty-four 
percent of respondents believe their organization
is in control of encryption keys for *both* data encrypted at the 
*application level* and at rest in the cloud
environment. Another 28 percent and 29 percent believe control of 
encryption keys is a *shared activity between**
**the organization and the cloud provider*. Only 19 percent and 17 
percent of respondents, respectively, view the
cloud provider as having control over encryption keys for either 
encryption at the application level or for data at
rest

[Figure 24]

Figure 25 shows German organizations are the most likely to say their 
organizations have control of encryption
keys *at the application level *and for data at rest in the cloud. 
Brazilian respondents are the least likely to say their
organizations have control over encryption keys at the application level 
and for data at rest in the cloud.

control of encryption keys*
