Microsoft's COM is a software(146)that allows applications to be built from binary software components. COM is the underlying architecture that forms the foundation for higher-level software services, like those provided by OLE. COM defines a binary standard for function calling between components, a way for components to dynamically discover the interfaces implemented by other components, and a mechanism to identify components and their interfaces uniquely.OLE is a compound(147)standard developed by Microsoft. OLE makes it possible to create(148)with one application and link or embed them in a second application. Embedded objects retain their original format and(149)to the application that created them. Support for OLE is built into the Windows and MacOS Operating Systems. A(150)compound document standard developed mainly by Apple and IBM is called OpenDoc.

With hundreds of millions of electronic(161)taking place daily, businesses and organizations have a strong incentive to protect the(162)of the data exchanged in this manner, and to positively ensure the(163)of those involved in the transactions. This has led to an industry-wide quest for better, more secure methods for controlling IT operations, and for deploying strong security mechanisms deeply and broadly throughout networked infrastructures and client devices. One of the more successful concepts to engage the imaginations of the security community has been the development of standards-based security(164 )that can be incorporated in the hardware design of client computers. The principle of encapsulating core security capabilities in(165 )and integrating security provisions at the deepest levels of the machine operation has significant benefits for both users and those responsible for securing IT operations.
