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.
