 Presentations
Enterprise
Security Architecture (ESA) - An Overview
This presentation provides an extensive overview of the current state of Enterprise
Security Architecture (ESA). Various definitions, existing models, and components
are presented along with a discussion of the relationships between the ESA
and the Technical Security Architecture (TSA). Federal military, federal civilian
and non-federal models will be discussed.
Technical Security Architecture (TSA) - Tying ESA to Operations
A complete Security Architecture program should contain both
enterprise-level and system-level guidance. Ideally the enterprise-level
guidance is part of the Enterprise Security Architecture
(ESA) process and system-level guidance is part of a Technical
Security Architecture (TSA) program. However, dealing with
numerous guidance sources and different ESA/TSA frameworks
can be challenging. The goal is to establish a strong TSA
program that is both seamless to the ESA and part of a complete
operations methodology.
This briefing
describes the basic concepts behind an effective TSA program,
how it compliments and reinforces an ESA program, and an
example of a TSA framework designed to tie into both the
ESA and operations frameworks
