A method, computer program product and computer system for securing alterable data. A computer that is remotely managed may be equipped with a protected storage that is accessible only by BIOS code. The protected storage may have the capacity to store a symmetrical encryption key. An EEPROM, which normally contains the BIOS code, may be used to store accessible configuration data as well as remotely unaccessible sensitive access information (e.g., passwords). The remotely unaccessible sensitive data is encrypted with the symmetrical encryption key by the BIOS code. Remote access to the sensitive data is accomplished via change requests submitted to the BIOS code over a secure channel. The BIOS code then determines whether the request is valid. If so, then sensitive data is decrypted, altered, encrypted, and re-written into the EEPROM. Normal access to accessible data is unaffected and remote access is allowed without changing the computer system architecture.

Prevention of unpermitted use of enabling bits is achieved by sealing the enabling bits to an environment in such a way that the bits can only be unsealed by or from the environment, and by using an isolation mechanism to isolate the environment from other environments on the machine on which the environment operates.
