In his keynote at Oracle OpenWorld 2015, Larry Ellison, Executive Chairman of Oracle Corporation and Chief Technology Officer, mentioned that "making security features optional may have made sense at one point, when security features like encryption had a greater impact on processing speed, but it doesn't make sense anymore." It is better to have security at the level of the processor than the operating system because silicon is more tamper-proof, and this is much safer than having it in software because software can be changed.
The philosophy behind security that organisations need to adopt is that it should be "always-on", and enabled by default across the entire technology stack and into the cloud for true safety.
Compute, Network and Storage are cloud units most people are familiar with -- Oracle has taken this further with DBaaS. Hence, we now have security capabilities for Secure Isolation, Access Control, Data Protection, Monitoring, and Auditing at every layer -- be it Compute , Network, Storage and Database.
