Cost-Effective Cybersecurity: A Multi-Tiered Defense Framework with Open-Source Solutions
Description
This book presents a comprehensive, research-driven framework for implementing cost-effective cybersecurity solutions through the integration of open-source security tools within a structured, multi-tiered defense model. Addressing the growing challenge of cybersecurity affordability, particularly for SMEs, educational institutions, and resource-constrained organizations, it offers a systematic approach to mitigating threats while ensuring scalability and resilience. The book provides empirical evaluations of security tools, real-world deployment insights, and practical implementation strategies, bridging the gap between theoretical cybersecurity principles and actionable solutions. By incorporating technical, economic, and strategic perspectives, it equips cybersecurity professionals, IT administrators, researchers, and policymakers with the knowledge to enhance security postures without incurring prohibitive costs. This publication stands out by offering a structured defense model, performance benchmarking of open-source solutions, and a forward-looking analysis of emerging threats, making it an essential resource for advancing cybersecurity resilience in financially constrained environments.
