The digitally duplicated environment is hardly a new concept. In fact, it was first applied in the manufacturing industry over 20 years ago before being popularized by John Vickers, NASA’s Principal Technologist, who coined the term "digital twin" in 2010.
However, the idea of using a digital twin as a means of studying a physical object dates back even further, with NASA’s pioneering use of digital twin technology during its space exploration missions of the 1960s. According to IBM (linked above), "Each voyaging spacecraft was exactly replicated in an earthbound version used for study and simulation purposes by NASA personnel serving on flight crews."
But it is only recently, with increasing volumes of computer horsepower and improvements in software, that the application of digital twin technology is becoming possible in the cybersecurity industry—and is set to become a powerful tool for the future.
What Is A Digital Twin?
A digital twin is a virtual replica of a physical system or asset, which enables simulation and modeling of real-world processes. Because the digital twin is informed by real-world data, it can be used to generate valuable insights and drive better decision making.
Rather than focusing on individual systems, a digital twin provides a comprehensive model that encompasses people, systems, processes and workflows. For example, it can accurately capture the order-to-cash process, which includes high-level corporate procedures and processes—including buying and selling activities and how money flows in and out of the organization.
The Role Of Digital Twins In Identity And Access Management
One area of cybersecurity that is particularly interesting for digital twins is their ability to create a holistic representation of an organization’s real-world identity and access environment. Historically, identity and access provisioning and orchestration had to be linear. However, over time and with advancements in tech, modern organizations need a more dynamic view of our identities and access.
Digital twins create a low-risk lens through which to view a model of your identities and access. They enable the application of artificial intelligence (AI) to simulate and predict potential changes in identity and access management (IAM). Using the digital twin combined with AI, organizations can test what-if scenarios and validate role-based access changes—assessing their impact on people, finances and technology.
Using a digital twin to model changes not only provides valuable insights but also facilitates smooth transitions without disruption to actual processes. What’s more, with a holistic view of their operations, IT teams can identify areas to optimize their IAM processes and eliminate redundant steps—helping organizations gain efficiencies and adapt to evolving business needs with greater confidence and precision.
Additionally, digital twin technology supports real-time monitoring and predictive analytics so that AI can respond swiftly to anomalies or security threats, preventing breaches before they occur.
Leveraging Digital Twins To Enhance Cybersecurity
Vulnerability Assessment
Digital twins are virtual replicas of an organization’s IT infrastructure, including their networks, systems and devices. By simulating various cyberattack scenarios, security teams can identify potential vulnerabilities and weaknesses without impacting the real-world environment. This allows for proactive risk assessment and mitigation to boost cyber resilience.
Incident Response Training
Harnessing digital twin technology, cybersecurity teams can create realistic incident response training that replicates actual cyberattacks in a virtual environment. This enables them to enhance their skills, test their incident response procedures and techniques and improve their overall readiness to effectively manage real-world security breaches.
Security Testing And Validation
Before deploying new security controls, patches or configurations in a live environment, these can be tested and validated using digital twins. Security teams are able to monitor the impact of changes on a virtual replica to identify any potential issues, issues, conflicts or performance degradation. This approach reduces the risk of introducing security vulnerabilities or disrupting business operations.
Threat Simulation And Analysis
Digital twins can simulate the behavior of potential cyber threats, such as malware, ransomware or advanced persistent threats (APTs). By studying how these threats propagate and impact the virtual environment, security researchers and analysts gain valuable insights into the increasingly sophisticated techniques used by cybercriminals. This knowledge can help in developing more effective detection and prevention strategies.
Security Architecture Design And Testing
When designing new security architectures or implementing security controls, organizations can leverage digital twins to test and validate their effectiveness. By first creating virtual models and modeling various cyberattack scenarios, IT teams are able to identify design flaws, performance bottlenecks or potential security gaps—refining and improving security architecture before deployment in a real-world environment.
When it comes to building a robust cybersecurity posture, digital twin technology is one of the most promising tools currently available. These use cases demonstrate how digital twins can provide a safe and controlled environment for cybersecurity testing, analysis and training—empowering organizations to reinforce security in vulnerable areas and proactively detect and respond to evolving cyber threats.
