A cyber range is a virtual environment designed to simulate real-world cyberattacks, security systems, and network operations for training, testing, and research purposes. It provides a safe and controlled platform where cybersecurity professionals, students, and organizations can practice detecting, responding to, and preventing cyber threats without affecting real systems. Cyber ranges are widely used for cybersecurity training, incident response exercises, ethical hacking, and security tool testing. They help users develop practical skills in areas such as malware analysis, penetration testing, network defense, and threat management. Governments, military organizations, educational institutions, and businesses use cyber ranges to improve cybersecurity readiness and strengthen digital defenses. Advanced cyber ranges may include artificial intelligence, cloud computing, and realistic attack scenarios to create hands-on learning experiences. These environments help organizations identify weaknesses in their systems and improve security strategies. As cyber threats continue to increase globally, cyber ranges play an important role in preparing skilled professionals and enhancing cybersecurity awareness, resilience, and protection in the digital world.
