Dual use refers to technologies, software, or products that are developed for legitimate civilian purposes but can also be adapted or misused for military or malicious activities. In cybersecurity, dual use technologies might include encryption tools, network monitoring software, or data analysis platforms that serve beneficial roles in protecting data and ensuring privacy. However, these same tools can be exploited by threat actors for espionage, cyberattacks, or surveillance. Understanding dual use is crucial for policymakers, businesses, and security professionals to balance innovation with security, regulate exports, and prevent misuse without stifling technological progress.
