You need to deploy Oracle Database Vault
We can deploy separation of duties through Oracle Database Vault and create realms as per your data domains.
Data in transfer can be secured by using encryption provided by Oracle Advance Security option of Enterprise Edition.
Data at rest can be secured by using Data Masking and subsetting pack
There may be many aspect to this question.
As far as security point of view there are algorithms like 'AES128' or AES264 which privide more comression amd add a level a security to the Data.
Answer to this question lies with the ORacle Vault.
It is a technique through which even a system administrator who has the control of the whole system would not be able to see the data without the key supplied by the Oracle Vault.
The ORacle vaults needs to open and running then only you would be able to access the data which would have a meaning.
This can be achieved through
by data vault
but even there is no one have the control of product only DBA can Enable Or disable this feature
