Cybersecurity is increasingly recognized as a human problem because many security breaches stem from human behavior rather than purely technical vulnerabilities. Factors such as user error, social engineering, and insider threats highlight the critical role people play in maintaining security. While technical controls like firewalls and encryption are essential, they cannot fully address risks that arise from human decisions and interactions. Understanding how individuals perceive, respond to, and manage security challenges is therefore vital for developing more effective protections.

Technical controls alone are insufficient because they often assume ideal user behavior and do not account for the complexities of human psychology and organizational culture. Attackers frequently exploit cognitive biases, lack of awareness, or routine habits, bypassing sophisticated defenses. As a result, security strategies must integrate training, awareness programs, and user-centered design to complement technological measures. This holistic approach acknowledges that securing systems requires addressing both the technical infrastructure and the human elements involved.

Artificial intelligence further transforms human trust and decision-making in cybersecurity. AI-driven tools can enhance threat detection and automate responses, but they also introduce new challenges related to transparency, reliability, and user reliance. People may either overtrust AI recommendations or dismiss them without sufficient understanding, affecting the overall security posture. The Cybersecurity and Privacy Research Lab (CPRL) exists to study these human factors, focusing on how individuals interact with security technologies and how to design systems that support better decision-making. By researching the human layer of security, CPRL aims to develop practical solutions that bridge the gap between technology and human behavior.
