Our team successfully delivered a compliant risk assessment to the ISA/IEC 62443 standard, identifying risks along with tangible economic solutions for the trains manufacturer to implement. The findings from our assessment not only highlighted areas of vulnerabilities, but also provided a roadmap for enhancing the security posture of the Class 196 train fleet. This comprehensive approach ensured that potential threats were mitigated, enhancing the safety and reliability of the fleet for both WMT and its passengers.

ISA/IEC 62443-3-2: Securing West Midlands Class 196 Train Fleet

Detailed security risk assessment resulting in risks identified and solutions provided to remediate the safety and security of the new Class 196 train fleet.

As part of our support, we were able to ensure RSA’s Cyber requirements for achieving and maintaining compliance using various security protection was upheld when deploying a fleet of 20,000 laptops. We also undertook a security evaluation audit, ensuring the new O365 accounts were conforming to RSA’s Information Security requirements to ensure the program could continue with the Digital Migration. We also developed and managed the deployment of a combination of migration endpoint security metrics into a centralized SIEM platform using ELK configured to provide alerting in this area.

We managed to identify a series of issues with the proposed architecture that could lead to potential malicious adversaries compromising the mobile app, should a particularl attack vectors be carried out. This resulted in our team working closely with the solution architects and developers to remediate our findings, such as leveraging native iOS and Kotlin libraries rather than using custom-built solutions for performing cryptographic and secrets management. We also reviewed the interaction between the mobile app and the backend infrastructure owned and managed by Tesco Banking and identified some issues around authentication of the app's microservices and addressed this by the introduction of introducing authentication methods for all calls made between the mobile app and backend IT Infrastructure.

Evaluating edge defenses using technology such as: Next-Generation Firewalls and ensuring Intrusion Detection/reverse proxy systems were in place at the ingress/egress of the Cloud environment provided some edge protection. Our team of security architects ensured that the Cloud environments were hardened to CIS benchmarks, but introduced compliance scanning at Code as Infrastructure level to ensure configuration of the Google environment was secure. We also ensure that when evaluating the solution from an assurance aspect, we ensure compliance against the Clients' security policies by leveraging tooling designed to pull data to indicate the configuration of the environments.
