Architecture Toolkit
The
Zachman Framework for Enterprise Architecture (ISA),1
defined
in 1987, is a logical construct to define and control the interfaces
and integration of all components of a system. The framework of the
Zachman model enables systematic capture of system specific
information from the various perspectives with respect to a system
architecture.
The
model is applied to capture the security policy of the existing
system to ensure the actual user requirements are understood prior
to system re-development. When this framework is complete, the
explicit, directive based security requirements can be applied and
overlaid into the framework, reconciling the implicit, working model
and the directive based model for the system’s security
requirements.

The Zachman Enterprise
Architecture framework for systems modeling provides a commonly used
technique that can be applied to security policy modeling early in
the system requirements definition process. By applying the top
three levels of the Zachman hierarchy, it is possible to develop a
descriptive security policy in simple English that can be understood
by the system consumer organizations.
Application of the
Zachman Model provides a technique to:
· express doctrine oriented
security requirements,
· reconcile these requirements
with the “as built” security requirements, and
· provide traceability for
requirements from specification to
implementation.
