Gross Domestic Product (GDP) is the total monetary value of all goods and services produced within a country's borders over a specific period, usually a year. It serves as a key indicator of a nation's economic health and size, allowing for comparisons between countries or tracking growth over time. In cybersecurity contexts, GDP is often referenced to compare national investments in technology, security infrastructure, or digital resilience, helping to assess how economic resources relate to cybersecurity readiness.
