Enabling the Intel TXT Feature in the BIOS
Intel Trusted Execution Technology (TXT) provides greater protection for information that is used and
stored on the business server. A key aspect of that protection is the provision of an isolated execution
environment and associated sections of memory where operations can be conducted on sensitive data,
invisibly to the rest of the system. Intel TXT provides for a sealed portion of storage where sensitive data
such as encryption keys can be kept, helping to shield them from being compromised during an attack
by malicious code.
