Your supply chain is at risk due to a vendor data breach. How do you protect your cybersecurity?

As a Chief Information Security Officer (CISO), I understand the critical importance of a thorough risk assessment in safeguarding our supply chain. We start by cataloging all vendors and evaluating the sensitivity of the data they handle. This includes scrutinizing their security policies, incident response capabilities, and historical security posture. We conduct detailed risk assessments to understand potential impacts on our systems in the event of a breach. By using risk matrices and threat modeling, we can prioritize vendors based on the risk they pose, ensuring our efforts are focused on those that could most significantly affect our operations.

I would also leverage quality, curated risk intelligence data for continuous / predictive monitoring of the most critical third party suppliers.

To me as a CISO, a 3rd-party data breach on their side can create many questions about our cybersecurity posture. Below a few top tips on assessing 3rd party risks to get you started. - Identify and rank all vendors & data they handle. - Evaluate security practices & prioritize high-risk vendors (data & integration). - Assign a single point of contact (SPoC) or a Vendor Relationship Manager (for high-risk vendors) to streamline communication, build a relation & info gathering. - Ditch lengthy forms! Use standardized assessments or on-site visits for high-risk vendors. Proactive steps like these can help you manage what you can control, vs. what is outside of your span of control.

To protect your cybersecurity in the wake of a vendor data breach, it's crucial to implement a comprehensive strategy. Here are the key steps to take: Immediate Actions Assess the Impact: Determine the scope and impact of the breach. Identify the data and systems affected.

It must also include communication strategies for both internal teams and external parties, such as customers, to manage the breach's impact effectively. Ensuring that the plan is clear and actionable helps mitigate damage and maintain trust during a crisis.

Apart from having a well crafted IR plan (very common to have in large to enterprise level organisations but not so common in SMB segment), the most crucial factors are to know where all each vendor’s solution, technology and services are being used. What level of access to data they have? What is the sensitivities of that data and how it could impact the organisation? This will help speed up the IR process at the time of cyber crisis. And most importantly these scenarios must be practiced by the organisations on a regular basis as part of Cyber Crisis Management Drills. In case anyone needs more information then I am happy to talk about it. Feel free to reach out.

**Incident Response Plan:** 1. **Preparation:** Establish IRT roles, define incident criteria, and compile contact lists. 2. **Detection:** Monitor systems for anomalies and classify incidents based on severity. 3. **Containment:** Isolate affected systems, preserve evidence, and apply mitigation measures. 4. **Eradication:** Investigate root causes and implement permanent fixes. 5. **Recovery:** Restore systems, validate functionality, and communicate progress. 6. **Communication:** Notify internal stakeholders, report to external parties, and manage PR. 7. **Post-Incident:** Conduct a thorough review, update policies, and document lessons learned.

Document an incident response plan explicitly about vendor data breaches. Refine roles and responsibilities, channels of communication, and conduct tabletop exercises to test for plan effectiveness.

In today's interconnected world, a vendor data breach can have far-reaching consequences. Having a robust incident response plan is crucial for swiftly addressing such breaches. Here are key elements your plan should include: 1. Quickly isolate affected systems to prevent further damage. 2. Identify and eliminate the threat to secure your environment. 3. Restore operations to normal as efficiently as possible. 4. Develop clear strategies for internal and external communication, including with customers, to manage the breach's impact effectively. 5. Conduct Post Completion Audit after the incident to take learnings and avoid repetition. A well-prepared response can make all the difference in maintaining trust and minimising damage.

Cybersecurity investment is relative to the size of an organisation and its ability to invest in security and resilience. Regardless of size, all companies are vulnerable. Supply chain attacks are an increasing vector for criminals or state actors as its often easier to breach a target. Honestly, it's virtually impossible to fully safeguard against. The primary goal should be to stop the attack early before the attacker can gain a foothold inside the infrastructure and cause damage. Zero Trust, XDR, Firewall all form a part of identifying the attack early to reduce it's impact. “There are only two types of companies: Those that have been hacked and those that will be hacked.” – Robert S. Mueller, III, former Director of the FBI.

ISOLATE, ASSESS, RESPOND In the event of a vendor data breach, some key steps to protect your cybersecurity could include: ISOLATE affected systems immediately to prevent further damage. ASSESS the breach to understand its scope and impact on your data and operations. RESPOND by notifying stakeholders, enhancing security measures, and conducting thorough audits of vendor practices. In general, it would be a best practice to implement stricter access controls and stronger third party-related policies, improve encryption, and ensure continuous employee training to fortify your defenses against future incidents of that type. Good luck!

Continuously consider and adjust your cybersecurity strategy based on the responding threats, companies' best practices, and regulatory requirements. Foster a cybersecurity awareness culture across your organization and through your vendor ecosystem.
