Trust and security

Any discussion of software trust must be based on fundamental understanding of the security-related system elements. These elements are:

• Privileges

• Trusted Facility Management (TFM)

• Discretionary Access Controls (DAC)

• DAC Isolation Mechanism

The next subsections give a general explanation of these elements of security and trust. There are other descriptions in Managing system security to which you may want to refer for other perspectives and information.
