Question

Security analysis of CPS systems

Cyber Physical Systems (CPS) have been deployed into critical infrastructures in industry,
healthcare, military, etc. As attacks to CPS can have very serious consequences for the integrity of
these infrastructures and the confidentiality of their data, it is essential to develop robust solutions to
protect CPS by identifying their security threats and preventing, detecting and mitigating attacks.
However, securing CPS is not a straightforward task due to the heterogeneity of connected cyber and
physical elements. With a wide variety of CPS elements, the framework of each may not be the same
— there may be different physical barriers, computational capacity, network protocols, etc. An
organisation needs to identify critical components, functions and operational procedures and ensure
that each is secure.
Discuss CPS security threats, focusing on the IoT domain, and critically analyse typical solutions for
preventing and mitigating attacks. Support your analysis by demonstrating a technique, procedure or
tool useful for securing, e.g., a smart home device, a Raspberry Pi or other (Linux) device. You can
do this on a physical device or using a virtual machine, IoT or cloud platform. Provide a description of
the setup, including relevant configurations, commands and screenshots

Answer 1

Cyber-Physical Systems (CPS) have diverse security threats in the IoT domain. Typical solutions for preventing and mitigating attacks include access control, encryption, and continuous monitoring.

Step-by-step explanation:

Cyber-Physical Systems (CPS) are deployed in critical infrastructures like industry, healthcare, and military. Securing CPS is challenging due to the heterogeneity of connected cyber and physical elements.

In the context of Internet of Things (IoT) domain, typical security threats to CPS include unauthorized access, data breaches, and malicious attacks. Preventing and mitigating these attacks can be done through techniques like access control, encryption, and continuous monitoring.

A technique useful for securing a smart home device or a Linux device like a Raspberry Pi is to use strong passwords and enable two-factor authentication. The device should be regularly updated with security patches and the network should be protected using firewalls and secure protocols like HTTPS. Additionally, implementing intrusion detection systems and using secure programming practices can enhance the security of CPS elements.
