Non Hardened Systems

Definition

Common hardening tactics readily found within traditional IT systems may be lacking in embedded environments. This can be the result of a simplified compute units, or other related simple systems that do not come with these hardening mechanisms built in.

How it works in robotics

In the realm of robotics, system hardening involves enhancing the security and resilience of robotic systems against potential cyber threats. The process is multifaceted, beginning with rigorous access controls to limit unauthorized interactions with the robot's software and hardware. Regular updates and patch management are essential to address vulnerabilities, as outdated firmware or software can become susceptible to exploitation. Implementing strong authentication mechanisms, such as biometrics or secure login credentials, adds an additional layer of defense. Encryption techniques play a crucial role in safeguarding communication between robot components and external systems. Furthermore, network segmentation helps isolate critical components, limiting the potential impact of a breach. Continuous monitoring and intrusion detection systems allow for the prompt identification of suspicious activities, while incident response plans enable quick and effective responses to potential security incidents. As robotics systems often operate in dynamic environments, the hardening process must consider both physical security measures and the integration of secure communication protocols to protect against unauthorized access and tampering. Overall, system hardening in robotics is a comprehensive approach that addresses various aspects to fortify the security posture of these intelligent machines.

Considerations

Embedded systems often work with limited or simplified compute units. These may not by default be equipped with expected hardening techniques, in software or in hardware. Confirm that the used system has the required security hardware and software configuration, do not assume it. Furthermore, update mechanisms may be suspect to attack.
