What do you do if your vendors and suppliers compromise your supply chain security?

Without a doubt, one of the biggest concerns of CISOs is the risks derived from the relationship with third parties. Evaluating the risks we place on our suppliers is one of the most difficult tasks we can face because many times these suppliers are imposed on us by the business. NIS2, the new European security directive, places a lot of focus on the supply chain and the need to evaluate and minimize the risk associated with it. In this sense we think that we are all on both sides because we are also part of our clients' supply chain. Before addressing the topic, we can start by thinking about what he said: "treat others as you would like to be treated."

'Avengers, assemble! We are dealing with a supply chain breach.' Invoke your CIR plan if you have one. If not, follow these. Immediately assess the extent of the breach and identify affected systems. Notify relevant stakeholders, including management and IT/security teams. Communicate with the vendor to understand the cause and scope of the breach. Implement temporary measures to mitigate the impact while investigating further. Review and strengthen supply chain security protocols and vendor management processes. Consider diversifying your supplier base to reduce dependency on a single vendor. Collaborate with industry peers and regulatory authorities to share best practices for supply chain security.

Taking prompt and decisive action, collaborating with vendors, and implementing robust security measures, you can mitigate the risks posed by compromised vendors and suppliers and safeguard your supply chain security.

If vendors compromise your supply chain security: 1. Assess the extent of the breach and impact on your organization. 2. Communicate with affected stakeholders transparently. 3. Implement immediate measures to mitigate risks and contain the breach. 4. Review and strengthen vendor security requirements and contracts. 5. Conduct regular audits and assessments of vendor security practices. 6. Consider diversifying suppliers to reduce dependency on vulnerable vendors. 7. Collaborate with industry peers to share threat intelligence and best practices. 8. Continuously monitor and adapt supply chain security measures to evolving threats.

When facing a compromise of supply chain security by vendors or suppliers, swiftly implement a response plan involving three key steps: First, assess the extent of the compromise by conducting a thorough investigation into the affected systems and data. Second, collaborate closely with the impacted vendors to mitigate the breach and strengthen their security measures to prevent future incidents. Finally, review and revise your supply chain risk management processes to include regular audits, vendor security assessments, and contractual clauses mandating adherence to robust security standards. This proactive approach ensures a more resilient supply chain and minimizes the risk of future compromises.

This is one of the most difficult yet essential part. When notifying stakeholders of a vendor Security breach, prioritize transparency and timeliness. Craft a clear and concise message outlining the nature of the breach, the data potentially affected, and the steps you're taking to contain the issue, mitigate damage, and prevent future occurrences. Tailor the communication based on stakeholder needs; provide more technical details to IT teams and focus on potential impacts for customers. I highly recommend being transparent as much as possible.

Inform relevant stakeholders within your organization, including senior management, IT security teams, legal departments, and affected business units, about the supply chain security breach. Communicate transparently and provide timely updates on the situation, including potential impacts and mitigation efforts.

The first step is to isolate the compromised vendor and prevent further damage. This might involve suspending data flows, disabling access, or taking affected systems offline. Work with the vendor to understand the extent of the breach. Identify what data was compromised, how it happened, and which systems are affected. Depending on the severity of the breach and the type of data compromised, you might need to notify your customers and potentially relevant authorities.

Take immediate steps to contain the threat and prevent further unauthorized access or exploitation of your organization's systems, data, and resources. Isolate affected systems or components within the supply chain to limit the spread of the compromise.

This should have been done earlier to prevent this, Work with the vendor to address the vulnerabilities that caused the breach. This might involve patching software, updating configurations, or implementing stricter access controls. This is a wake-up call to strengthen your own Security posture. Review your vendor selection process and implement stricter security assessments for future partnerships.

Work closely with the compromised vendors and suppliers to identify and remediate the vulnerabilities or security weaknesses that contributed to the supply chain compromise. Implement security patches, updates, or configuration changes to mitigate the identified risks and strengthen the overall security posture of the supply chain.

Reviewing policies involves a systematic examination to ensure they are effective, up-to-date, and aligned with current needs. This process typically involves gathering relevant stakeholders, thoroughly reading and analysing the policies, identifying any gaps or inconsistencies, and proposing revisions or complete rewrites. The goal is to create clear, concise, and enforceable policies that promote a safe, secure, and efficient work environment.

Review and revamp your security protocols, especially your vendor management policies is to ensure supply chain security never takes a hit. Make sure they're rock solid with strict security requirements and regular check-ins. Learn from the breach to fine-tune your incident response plan for quicker and smarter reactions next time. Get everyone involved in the review process to build a tight-knit culture of security awareness across your organization.

Review and revise your organization's supply chain security policies, procedures, and contractual agreements with vendors and suppliers to ensure they align with best practices and regulatory requirements. Incorporate specific security requirements, such as risk assessments, security audits, and incident response protocols, into vendor contracts and service level agreements (SLAs).

It is better to sign a service level agreement (SLA) with the vendor if it's a critical service. The SLA should define the disruption/issue fixing timelines and how the issue is escalated. Additionally, priority levels can be set based on the type of the issue (e.g., if the business impact is low - 24 hours, if the impact is medium - 4 hours, if the impact is high - 1 hour, etc.). Also, you can obtain the same service from two vendors to avoid a single point of failure (ISP etc.)

Foster stronger partnerships and collaboration with trusted vendors and suppliers who prioritize security and demonstrate a commitment to mitigating supply chain risks. Establish regular communication channels and mechanisms for sharing threat intelligence, security updates, and best practices with partners.

Sin lugar a duda una de las mayores preocupaciones de los CISOs son los riesgos derivados de la relación con terceros. Evaluar los riesgos que depositamos en nuestros proveedores es una de las tareas más difíciles a las que nos podemos enfrentar porque muchas veces estos proveedores nos vienen impuestos desde negocio. La NIS2, la nueva directiva europea de seguridad, pone mucho foco en la cadena de suministro y en la necesidad de evaluar y minimizar El riesgo asociado a ella. En este sentido pensemos que todos estamos en los dos bandos porque también formamos parte de la cadena de suministro de nuestros clientes. Antes de abordar el tema, podemos empezar por pensar aquello que decía: "trata a los demás como te gustaría que te tratasen".

Conduct post-incident reviews and lessons learned sessions to analyze the root causes of the supply chain security compromise and identify opportunities for improvement. Implement proactive monitoring and threat intelligence capabilities to detect and respond to potential supply chain security threats in real-time. Stay informed about emerging supply chain security risks and trends, and continuously adapt your security strategies and practices to mitigate evolving threats.
