Oracle Exadata Database Server X8-8 uses Trusted Execution Technology (TXT), which provides authenticity of a platform and its operating system.
When enabled, TXT ensures that the operating system (OS) starts in a trusted environment, and provides the OS with additional security capabilities not available to an untrusted OS. Using cryptographic techniques, TXT provides measurements of software and platform components so that system software as well as local and remote management applications may use those measurements to make trust decisions. Trusted Execution Technology defends against software-based attacks aimed at stealing sensitive information by corrupting system or BIOS code, or modifying a platform's configuration.
Trusted Execution Technology is disabled by default. For configuration information, see Configure Trusted Execution Technology.
