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essential to address vulnerabilities, as outdated firmware or software can become susceptible to exploitation.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.
