Security Architecture and Design

Enterprise Security Architecture
• Goals can be strategic (long term), tactical
(midterm), or operational (short term)
• Note that the labels (strategic,
tactical, and operational) can vary
from different sources. The important
point is that at the lowest level are
the people who do the job, at the
mid-level are the people who manage
the job, and at the top level are the
people who decide what job to do.
CISSPs are typically at the mid or top
levels.
• Your solutions approach can be enterprise
solutions (with management support) or
point solutions (no management support).
• Deming was the “father” of total quality
management (TQM)
• Zachman framework: two-dimensional
classification scheme (levels of architecture
& levels of interest).
• Other frameworks include COBIT, COSO,
ITIL, CMMI, SEI IDEAL, TOGAF, and ISO
42010:2007.
