Why did crime-related security systems grow rapidly after the 1960s?

The rapid growth of crime-related security systems since the 1960s is attributed to several interconnected factors that reflect the evolving nature of modern society and technology.1

Key drivers for this expansion include:

• Business and Information Sensitivity: There has been a significant increase in the number of security-sensitive businesses and a growing need to protect proprietary information.1
• Technological Vulnerabilities: The increasing computerization of sensitive data has created unique vulnerabilities, necessitating more robust protective measures.1
• Heightened Awareness: Improved methods of reporting crime have led to a wider public and institutional awareness of security needs.1
• Security Threats: Many countries have faced an escalating need for protection against specific threats, including violent demonstrations, bombings, and hijackings.1

These developments have been supported by rapid advancements in electronics and miniaturization, which have made security hardware—such as intrusion-detection devices—more reliable, automated, and easier to install.1
