What Happens When the Security Vendor Becomes the Incident

Having worked as a firefighter in a previous life, I saw firsthand the vital work done by my town’s dispatch office. At the fire department, we received several alerts from dispatch throughout the day with details about reported fires and emergencies requiring a response. Day in and day out, through rain, sun, or snow, dispatch operated 24/7 and kept our emergency services running smoothly.

But because dispatch was the glue that kept all our services connected and communicating, I always wondered: What would happen if the dispatch office caught fire?

Who would dispatch the fire department?

Staying Ahead of Vendor Compromise

When I shifted from putting out physical fires to digital ones, it turned out that question remained surprisingly relevant. From managed security service providers and Software as a Service platforms to the ticket management tool shared across an entire organization, it takes a long list of vendors and solutions to secure everyday business operations. Each of these solutions supports vital business functions and, because of that, also represents a potential point of failure.

Put plainly, cybersecurity tools and the companies that develop them can be compromised. Organizations need plans in place to address when that happens.

The old saying applies here: “An ounce of prevention is worth a pound of cure.” With that in mind, companies should perform a business impact analysis before onboarding a new vendor. This helps ensure that stakeholders understand how a disruption to the vendor’s services could affect business functions, what company data or assets could be exposed during an incident, and which alternative workflows may be needed during the disruption.

While each vendor should be evaluated separately to determine specific remediation needs, organizations should also maintain a general vendor compromise playbook, just as they might maintain a playbook for a phishing email or malware incident. This document should identify the teams and stakeholders to engage during an incident, as well as the actions incident response analysts should take.

Depending on the scope of the compromise, remediation actions might include rotating shared secrets such as passwords, keys, tokens, and certificates; disabling service accounts; and, in extreme situations, blocking network access from the vendor’s services.

How K logix Helps

K logix helps organizations prepare for and reduce the impact of third-party and security vendor compromise. We work with security teams to understand vendor criticality and potential business impact, strengthen response planning, and improve visibility into third-party risk.

Whether evaluating current preparedness or identifying gaps, the goal is to ensure organizations are ready when a trusted vendor becomes part of the incident.
