Guidelines for Dealing with a Data Breach from Suppliers
In today's digital age, businesses are increasingly vulnerable to cyberattacks, especially those involving third-party vendors. To protect your company's data and minimise the impact of such attacks, it's crucial to follow a well-structured response plan. Here's a step-by-step guide on how to respond effectively to a cyberattack on a third-party vendor.
1. **Immediate Investigation and Assessment**
Confirm the breach details with the vendor, understanding what data, systems, or access were affected and whether your business data is compromised. Conduct a risk assessment to identify the scope of impact on your organisation’s assets and data.
2. **Activate Your Third-Party Incident Response Plan**
Ensure your incident response plan includes specific provisions for third-party incidents, with clearly defined boundaries, roles, and responsibilities to enable a swift, coordinated response. This plan should have been established through prior vendor risk assessments and must address the types of incidents covered.
3. **Containment and Mitigation**
Work with the vendor and your cybersecurity team to isolate affected systems, quarantining endpoints or segments of networks or temporarily disabling access to prevent further spread. Remove malware, apply necessary security patches, and revoke compromised credentials immediately.
4. **Communication and Coordination**
Maintain clear communication channels between your organisation, the vendor, and other stakeholders, including legal, compliance, and public relations teams. Ensure all communications are accurate and timely, including regulatory notifications if required by laws such as GDPR or HIPAA.
5. **Recovery and Restoration**
Use verified and tested backup processes to restore business systems safely after threat eradication. Confirm restored data integrity and the security posture of systems before full operational resumption. Increase monitoring intensity during recovery to detect any residual threats.
6. **Post-Incident Review and Risk Reduction**
After recovery, perform a thorough review of the incident to identify vulnerabilities and improve defences. Strengthen vendor management by vetting suppliers’ security certifications, limiting data shared, regularly reviewing access rights, updating contracts with breach notification and responsibility clauses, and integrating vendors in your incident response planning.
In case of a vendor's data breach, prompt response is key to keeping your information safe. Other preventive measures include purchasing identity theft insurance for the business and integrating multifactor authentication software into cybersecurity. IT professionals must remain vigilant, but a swift and professional response is crucial in case of a cyberattack.
Cyberattacks can have widespread effects, such as stealing valuable data for ransom or crippling a business's supply chain. Common types of cyberattacks include phishing and credential stuffing. Phishing involves fake domains and attempts to reveal sensitive information or introduce malware, while credential stuffing injects stolen credentials into multiple login forms to gain access.
If a cyberattack on one of your third-party vendors is successful, ask the vendor questions such as whether the attacks are still occurring, if the data breach has been stopped, how the attackers gained access, if there was an information leak, if someone was responsible, and if so, whether it was intentional. Also, inquire about the vendor's cyber insurance and whether they will cover your legal fees if a lawyer is needed to evaluate breach notification obligations.
It's alarming that about 56% of companies have experienced a data breach caused by one of their vendors. Cyberattacks are indiscriminate, targeting businesses from various sectors, including automotive companies, steel manufacturers, and prisons. Therefore, it's essential to ask your vendor if the data leak can compromise your system. The vendor should have immediately launched an investigation when the breach occurred.
In conclusion, a coordinated response to third-party cyberattacks helps protect business data and minimises operational and reputational impact. Having a detailed third-party incident response plan in place before an incident occurs is essential for rapid and effective action.
- In the event of a phishing attack, it's essential to look into cyberscurity forensics to determine the extent of the damage and to identify the attack's origin.
