What is a cyber range?

Cyber ranges are modern battlefields for cybersecurity. Much like traditional shooting or military ranges that act as proving grounds for marksmanship and combat skills, cyber range platforms provide users with a safe environment to practice responding to real-world cyber challenges.

Within a secure and controlled setting, cyber ranges simulate complex networks and threats for cybersecurity training, allowing participants to learn and refine their strategies for defending against digital attacks. These training exercises offer realistic, real-time scenarios without putting actual systems at risk.

Using virtual machines, cyber ranges create realistic training environments that can be easily segmented from other networks such as a corporate LAN or the internet at large. These environments provide a safe space for experimentation and testing various cybersecurity tools and functionality.

Target infrastructures within the cyber range mirror actual servers, firewalls, routers, storage devices, and personal computers. This allows users to deploy real-world cybersecurity tools such as penetration testing, intrusion detection systems and digital forensics tools. Participants can also safely practice defending against specific cyberthreats such as malware and ransomware.

The NIST Cybersecurity Framework, which was designed by the National Institute of Standards and Technology (NIST), is commonly used in cyber ranges. The NIST framework is a guide based on five core functions—identify, protect, detect, respond, and recover—that provides a structured approach to cybersecurity strategy and risk management.

By incorporating the NIST framework into cyber range exercises, organizations can align their training with industry standards and best practices. This offers participants practical, real-world experience and enhances the organizations’ security posture.

A cyber range often features a learning management system (LMS) for organizing coursework and tracking students' progress and performance. Instructors use the LMS to define the curriculum and facilitate communication, assignments, and assessments. By combining advanced technology with targeted learning and testing opportunities, cyber ranges prepare cybersecurity professionals to confront evolving challenges.

There are 4 common types of cyber ranges:

• Simulation ranges replicate the behavior of real-world networks and systems. They use software simulations and provide an efficient, cost-effective environment for training and testing without the need for extensive hardware.
• Emulation ranges mimic the actual hardware and software configurations of a real-world network, offering a high degree of realism for practicing with specific technologies and setups.
• Overlay ranges use real hardware and networks that are overlaid with virtual elements to simulate different scenarios, offering a mix of realism and flexibility.
• Hybrid ranges combine elements of simulation, overlay, and emulation to create a versatile environment that balances realism, cost, and resource efficiency.

A cyber range consists of various technical components that work together to create a realistic and controlled environment for cybersecurity training, testing and research:

Cyber ranges were originally used primarily by military and government agencies. They are now used by a broad range of businesses and organizations due to their cost-effectiveness and valuable opportunities to upskill security team members. Cyber ranges offer essential training for various people and groups:

1. Bug bounty hunters: Cyber ranges provide bug bounty hunters with a safe environment for researching security issues and discovering new vulnerabilities, helping them find and report bugs to developers and manufacturers.
   
   
2. Cybersecurity professionals: Security analysts, penetration testers, ethical hackers, and other professionals use cyber ranges to refine their skills. They offer real-world practice, allowing professionals to keep up with emerging threats and learn new defense techniques.
   
   
3. Government and military and agencies: As some of the first users of the internet, military and government agencies depend on cyber ranges to maintain national defense and data safety. Cyber ranges aid government personnel in handling the latest cyberthreats, including cyber warfare and espionage.
   
   
4. IoT and smart grid developers: Developers and engineers working on Internet of Things (IoT) devices or smart grid technologies can use cyber ranges to test the security and resilience of their products.
   
   
5. Organizations and individuals: Companies can use cyber ranges for situational operations testing, training, and assessing candidates for cybersecurity positions. Individuals entering cybersecurity roles can benefit from the workforce training cyber ranges offer.
   
   
6. Researchers: Academics and researchers can use cyber ranges to study cybersecurity trends, conduct experiments, and test new tools and technologies in a controlled setting.
   
   
7. Security trainers and educators: Instructors, educators, and facilities such as security operations centers (SOCs) can use cyber ranges as platforms for teaching cybersecurity courses and developing training programs that provide students with practical, hands-on experience.
   
   
8. Students: Cyber ranges are now a key component of a top-tier cybersecurity education. They provide students pursuing certifications or degrees with practical experience through hands-on labs, enhancing their learning with realistic scenarios.

Cyber ranges are a critical tool for cybersecurity professionals. They offer a safe and controlled training platform for cybersecurity workforce development. Here are several reasons why cyber ranges are important:

1. Addressing the talent gap: By offering practical training, cyber ranges help close the skills gap in the cybersecurity workforce by preparing individuals with job-ready skills.
   
   
2. Continuous learning: Cyber ranges offer on-demand, ongoing opportunities for cybersecurity professionals and students to enhance their cyber skills, keeping them up-to-date with the latest cyberdefense strategies and tools.
   
   
3. Controlled environment: Cyber ranges provide a safe space for trial and error. This allows for repeated and reusable training scenarios without impacting live systems and enables experimentation and learning without risking damage to real data and networks, helping to prevent data breaches.
   
   
4. Incident response practice: Participants can practice and refine incident response plans in the range, learning how to use established playbooks and adapt to various threats. This experience enhances their readiness and confidence.
   
   
5. Keeping up with evolving threats: Cyber ranges allow individuals to stay current with emerging cyberthreats and techniques and prepare them for real-world challenges.
   
   
6. Performance assessment: Cyber ranges provide metrics and feedback to evaluate individual and team performance. These measurements help identify areas for improvement and enable tailored training for optimal results.
   
   
7. Realistic training: Cyber ranges use realistic attack scenarios and network simulations in a controlled, safe environment for practicing cybersecurity skills. Trainees develop hands-on experience and confidence in handling real-world threats without the risks that are associated with practicing on live systems.
   
   
8. Skills development: Trainees can hone their abilities to detect, prevent, and respond to cyberthreats. Cyber ranges help professionals stay updated with the evolving attack methods and defense strategies and help them enhance critical thinking, problem-solving skills, and confidence.
   
   
9. Team collaboration: Cyber ranges enable teamwork and coordination as participants work together on complex scenarios. This fosters effective communication and teamwork in high-pressure situations and prepares security teams for coordinated incident response.
   
   
10. Testing and research: Organizations can test new security tools and approaches within a cyber range, developing innovative solutions and assessing their efficacy. This enables safe testing of new technologies and supports ongoing research to improve cybersecurity measures.
