In the digital age, cybersecurity threats evolve at a rapid pace, presenting challenges that outstrip traditional defense measures. Despite the breadth of existing proprietary security solutions, these often come with high costs and limited flexibility, constraining their adoption and adaptability to dynamic threat landscapes. This highlights a critical gap in the provision of cost-effective and scalable cybersecurity measures, particularly for organizations with limited resources. The research herein underscores the necessity for a comprehensive evaluation of open-source cybersecurity tools to mitigate these constraints. Addressing this need, our work systematically surveys the domain of open-source cybersecurity tools, identifying their potential to offer a resilient, adaptive, and financially accessible multi-tiered defense framework. We propose a novel six-layered model that integrates these tools into a cohesive strategy, covering detection and prevention, endpoint protection, investigation and recovery, SIEM, IAM, and security awareness and training. The model advocates for an open collaborative approach, capitalizing on community-driven innovations to create a sustainable and continually evolving cybersecurity defense posture. Through this research, we aim to empower organizations to construct robust, adaptive, and cost-efficient cyber defenses, thereby enhancing their resilience against an ever-changing array of cyber threats.
