Despite the advantages of digital twin technology for increasing efficiency and production, several security concerns and obstacles are associated with its widespread use. Therefore, before using digital twin technology, it is essential to consider the following significant security concerns.

1. Reconnaissance

Sniffing packets and bandwidth is part of reconnaissance. Attackers can use these methods to count devices, find security flaws, and uncover vulnerabilities. Unauthorized access to private information and exploiting weaknesses in the CPS and its digital twin are possible outcomes of such attacks.

Attackers can, for example, monitor network activity and intercept network packets to identify which CPS components are operational or to deduce CPS activity from the bandwidth usage between the CPS and its digital counterpart. The bandwidth between the CPS and its digital twin may allow attackers to estimate the potential protocols, even if the network packets cannot be adequately decrypted or analyzed.

Once network data has been effectively intercepted, attackers can learn more about the CPS's communication with its digital duplicate. The next section will include reconnaissance-based attacks, such as model injection, data injection, and data delay.

2. Attacks Using Data Injection

Interaction between real and digital components needs to be carefully controlled because of the inherent data dependency and requirement for reliability. One attack technique involves introducing malicious commands or bogus status reports to fool the system. The assault methods listed below have the potential to either interfere with the cyber-physical system or give digital twins inaccurate information.

1) To gain control of the CPS, attackers send particular orders that should come from the digital twin. Attacks like these aim to take control of CPS devices or harm and destroy them, preventing the digital twin from operating the CPS and leading to simulation failures.

2) Attackers trick digital twins by sending packets to show the CPS's current state. This kind of attack has the potential to confuse and malfunction by causing the digital twin to obtain inaccurate data from the CPS.

3. Data Delay Attack

Digital twin technology relies heavily on real-time synchronization between the virtual and real worlds. Attackers might try to break this synchronization, though, by adding many communication delays. Attackers may overload the network to affect the physical or digital twin and create these kinds of delays.

Attacks of this kind are comparable to denial-of-service (DoS) attacks. To carry out such an assault, attackers don't even need to comprehend ICS protocols or features. The digital or physical twin may not react promptly during a timeout, which could cause both twins to behave unexpectedly.

4. Model Corruption

Directly injecting unauthorized software is another way to throw off the synchronization between the physical and digital twins. If an attacker manages to get access to the environment, they might, for example, look through the repositories, examine the code, and insert malicious code to distort the model. The digital twin is impacted as soon as the model is compromised. The output may become inconsistent if the digital twin can no longer faithfully depict the physical twin.

As an alternative, attackers can introduce harmful code into model-building libraries. Additionally, models created using compromised libraries are tainted. As a result, the digital twin may be compromised and lose its ability to faithfully depict the physical twin, which could result in inconsistent output.

5. User Data Breach and IP Leakage

Attackers may be able to obtain sensitive data acquired by physical twins, such as sensor values, data from the Internet of Things devices, and more after digital twin technology is compromised. In a production setting, this data usually requires more effort to access. However, recovering sensitive data from a leaked digital twin is easier. The physical twin could also contain priceless intellectual property (IP), frequently a vital business resource.

Furthermore, as the GDPR demonstrates, many firms today place a high importance on preserving privacy. If a digital twin is compromised and contains client information, the company may sustain not just monetary losses but also harm to its reputation.
