The Importance of Openness and Sharing in Defending Critical Infrastructure

In the realm of cybersecurity, the ever-growing sophistication of cyber threats has put a spotlight on the need to protect critical infrastructure. State-sponsored actors, exemplified by the infamous Volt Typhoon group, have been relentless in targeting critical infrastructure using advanced cyber techniques. The implications of such attacks are profound, ranging from significant disruptions to infrastructure functions to threats on democracy, global economic stability, and potentially even loss of life. In response to these grave challenges, the call for enhanced cybersecurity measures has never been more urgent; it is a matter not just of security, but of public safety and national well-being.

The Volt Typhoon group, reportedly linked to China, has established itself as a major player in the realm of cyber-espionage through its adept use of stealth techniques to infiltrate critical infrastructure networks. With a primary focus on US military and government entities, Volt Typhoon exploits vulnerabilities in target environments, utilizing tactics that emphasize the use of existing legitimate tools and processes to evade detection. Eschewing the traditional malware approach, this group’s strategy makes it particularly challenging to detect and track their activities.

To effectively respond to these sophisticated cyber threats, transparency and information sharing are crucial components. In the event of a cyber incident, swift action is paramount not only for the affected organizations but also for government agencies tasked with investigating and mitigating these attacks, especially when state-sponsored actors are involved. Transparency facilitates coordinated and timely responses to prevent incidents from escalating.

One significant tool in the cybersecurity arsenal is the software bill of materials (SBOM), which has been recognized by the US federal government as vital for enhancing cybersecurity. By providing a detailed inventory of software components and dependencies, including open-source and third-party elements, SBOMs offer a critical line of defense against attacks like those orchestrated by Volt Typhoon. When coupled with the Vulnerability Exploitability eXchange (VEX) document, organizations gain a comprehensive understanding of their environment, enabling informed decisions to bolster their security posture.

Moreover, the importance of forging strong partnerships between the public and private sectors cannot be overstated in the fight against cyber threats. Public-private collaborations enable the sharing of intelligence on emerging risks, fostering a continuous exchange of critical information that enhances collective resilience. Through strategies like SBOMs, organizations can establish trust-based relationships that facilitate open communication about threats and vulnerabilities, leading to swifter resolution of cybersecurity issues.

Internally, organizations must prioritize enhanced visibility into their IT systems, particularly in the face of increasingly complex infrastructures. Solutions like observability offer real-time insights into system status, enabling IT teams to detect anomalies promptly and take proactive measures to prevent incidents. The SolarWinds Secure by Design initiative exemplifies a comprehensive approach to cybersecurity resilience, emphasizing transparency, innovation, and collaboration across sectors.

Ultimately, the evolving landscape of cyber threats necessitates ongoing collaboration and innovation to confront the challenges posed by cybercriminals and nation-state actors. By leveraging tools like SBOMs, observability, and partnerships between public and private entities, organizations can fortify their defenses and build a more secure future. Through united efforts, the cybersecurity community can create a safer environment capable of standing up to the complexities of modern cyber threats.
