For gathering strategic threat intelligence that provides a high-level overview of the current cybersecurity posture, potential financial impacts of cyber activities, and overarching threats, sources such as Open Source Intelligence (OSINT), Cyber Threat Intelligence (CTI) vendors, and Information Sharing and Analysis Organizations (ISAOs)/Information Sharing and Analysis Centers (ISACs) are invaluable. OSINT involves collecting data from publicly available sources, CTI vendors specialize in providing detailed threat intelligence services, and ISAOs/ISACs facilitate the sharing of threat data within specific industries or communities. These sources can provide broad insights into threat landscapes, helping organizations understand how to align their cybersecurity strategies with current trends and threats.References:
