I need to secure our Oracle db from unauthorized changes to the schema. The db is not in a development\production environment. It is strickly holding non-sensitive data, however, one of our security requirements is to have the Oracle Database Source Code Object Encryption - encrypted. Is the wrap utility used for this purpose? What does obfuscation offer? We simply do not want the existing Oracle schema to be tampered with and become unusable. Could someone clarify if the wrap utility or obfuscation utility is only used for a development environment or could it be used to protect the existing Oracle db schema?
