A Library of Architectural Frameworks for IT and Cybersecurity Professionals
This document provides a comprehensive overview of key architectural frameworks for IT and Cybersecurity professionals. It covers Enterprise Architecture (EA) frameworks like TOGAF and the Zachman Framework, which focus on holistic enterprise design and management. It also details Cybersecurity frameworks and models including SABSA, the NIST Cybersecurity Framework (CSF), and Zero Trust Architecture (ZTA), offering guidance on managing cyber risk and designing secure systems.
Each framework is analyzed regarding its description, uses, pros and cons, practical application examples, and links to associated governing bodies and official guidance resources. The document aims to serve as a reference library for understanding these frameworks and their applications in improving business efficiency and establishing resilient security postures.
Zone Architecture in Enterprise IT and Security
This article discusses Zone Architecture as a strategy for dividing an organization's network into distinct segments based on criteria like business function or data sensitivity. It covers the definition, core principles, advantages (such as reduced attack surface and improved scalability), and challenges of implementing Zone Architecture.
The article also explores various implementation approaches, its role in achieving business objectives, and how it enhances data protection and cybersecurity. It provides reference architectures for on-premises and Azure cloud environments, and discusses extending Zone Architecture to multi-cloud and hybrid environments. The conclusion emphasizes strategic considerations and future trends like micro-segmentation and integration with Zero Trust models.
