The underlying layer of the OPC Data Access (DA) specification is based on Microsoft's COM/DCOM technology, which enables inter-process communication in a variety of programming languages for the Windows operating system. In modern operating systems, processes are encapsulated to provide increased stability and security. COM provides a communication interface layer that allows local and remote procedure calls between processes. DCOM (Distributed COM) is the natural extension of COM to support communication among objects on networked computers

DCOM can achieve security transparency, making distributed applications secure without any security-specific coding or design in either the client or the component. This is because DCOM lets developers and administrators configure the security settings for each component. Just as Windows operating systems allow administrators to set Access Control Lists (ACLs) for files and directories, DCOM also stores ACLs for components. These ACLs indicate which users or groups of users have access to a component of a certain class. For additional specifications on DCOM security, refer to the DCOM Technical Overview paper on the Microsoft TechNet website.
