Securing Edge Computing on PON with Open-Source Software: Lessons from Industrial R&D

The paper Security-by-Design at the Telco Edge with OSS: Challenges and Lessons Learned was published on April 30, 2025. It explores the secure development of edge computing platforms in optical networks using open-source tools and discusses the practical challenges faced during an industrial research project.

The paper details efforts to secure GENIO, a platform for edge computing on Passive Optical Network (PON) infrastructures, using Open-Source Software (OSS). It identifies threats and applies mitigations such as hardening, vulnerability management, digital signatures, static, and dynamic analysis. The research highlights lessons learned in implementing these measures with OSS, assessing their maturity and limitations within an industrial context.

In an age where digital infrastructure forms the backbone of modern life, safeguarding systems from cyber threats has become a matter of critical importance. As technology evolves at breakneck speed, so too must the tools and frameworks designed to protect data, applications, and networks. This article delves into some of the most effective cybersecurity tools and practices currently in use, underscoring their role in fortifying digital assets against an ever-growing array of threats.

The Growing Complexity of Cybersecurity

The increasing sophistication of cyberattacks has necessitated a corresponding evolution in security measures. From containerized applications to cloud-based systems, every layer of the digital ecosystem demands meticulous protection. Tools such as Docker Bench Security, Kube-bench, and Trivy have emerged as indispensable components in this effort, enabling organisations to identify vulnerabilities and strengthen their defences against potential breaches.

The Development of Cybersecurity Frameworks

The creation of these tools relies on a combination of automated scanning, policy enforcement, and continuous monitoring. For example, Docker Bench Security provides a set of best practices for securing Docker containers, while Kube-bench ensures that Kubernetes clusters adhere to industry standards. These frameworks are designed to integrate seamlessly into existing workflows, allowing organisations to maintain security without disrupting operations.

Tools like Docker Bench Security and Kube-bench play a pivotal role in securing containerized environments. By enforcing strict access controls and ensuring that configurations align with best practices, these tools significantly reduce the risk of exploitation. Their ability to integrate into existing workflows makes them invaluable for organisations seeking to maintain security without disrupting operations.

Trivy and OWASP Dependency-Check are critical for identifying vulnerabilities in software dependencies. These tools enable organisations to stay ahead of potential threats by continuously monitoring their supply chains for insecure components. By addressing these issues proactively, organisations can mitigate risks before they escalate into full-blown breaches.

Frameworks such as Falco and Kubearmor provide real-time monitoring and threat detection, helping organisations respond swiftly to emerging threats. These tools are particularly effective in identifying and mitigating potential attacks before they cause significant damage.

As cyber threats continue to grow in complexity and frequency, the need for robust cybersecurity measures becomes increasingly apparent. Tools such as Docker Bench Security, Kube-bench, Trivy, Falco, and Kubearmor represent just a few of the essential components in this ongoing effort. By leveraging these tools and adopting best practices, organisations can better protect their digital assets and maintain the trust of their stakeholders.

In an era where data breaches can have far-reaching consequences, cybersecurity is no longer an optional consideration but a critical imperative. The tools and practices discussed here represent a starting point for organisations seeking to fortify their defences against an ever-evolving threat landscape.
