#### 📝 Summary: The document discusses various challenges related to software security in OT and ICS, particularly when using Open Source Software. #### 📖 Main Content: The challenges include dependency vulnerabilities, lack of commercial support, and inadequate documentation. These challenges make it difficult for organizations to manage their software securely. #### 🔮 Future Research: Investigation into how organizations are overcoming these challenges and what best practices are emerging. #### 🧪 Hypotheses: 1. Organizations that address these challenges proactively will have a more robust cybersecurity posture. 2. Dependency vulnerabilities are the most significant challenge faced by organizations. #### 📊 Methodology: Interviews with IT managers and security audits could provide insights into how organizations are addressing these challenges. #### 💡 Implications: Understanding and overcoming these challenges are crucial for improving the cybersecurity posture of critical infrastructure. #### 📖 References: - CISA PDF: [Link](https://www.cisa.gov/sites/default/files/2023-10/Fact_Sheet_Improving_OSS_in_OT_ICS_508c.pdf) ## Links - [[3.
