Page 124 PaaS encryption varies tremendously due to all the different PaaS platforms. • Application layer encryption: Data is encrypted in the PaaS application or the client accessing the platform. • Database encryption: Data is encrypted in the database using encryption that’s built in and is supported by a database platform like Transparent Database Encryption (TDE) or at the field level. • Other: These are provider-managed layers in the application, such as the messaging queue. There are also IaaS options when that is used for underlying storage.

A. PaaS is very diverse and may include client/application, database, and proxy encryption as well as other options. PaaS (Platform as a Service) is a cloud computing service model that provides a platform for developers to build, deploy, and manage applications without managing the underlying infrastructure. PaaS offerings can be diverse, and the encryption options available within a PaaS environment can vary. It can include various encryption measures such as client/application, database, and proxy encryption, along with other security features. The range of encryption options depends on the specific PaaS provider and the services they offer.
