Background for this topic.

Vendor is an external organization that supplies an IT product or service, such as software, hardware, cloud hosting, or managed security. In security reporting, the term usually concerns a third party whose technology, personnel, or connectivity forms part of an organization’s environment or handles its data.

Vendor risk depends on the access and dependency involved. A compromised or poorly secured vendor can expose customer information, introduce vulnerabilities through software updates or components, or provide attackers with a route into connected systems. Practical controls include risk-based due diligence, contractual security and notification requirements, least-privilege access, vulnerability and software-supply-chain review, monitoring, and prompt removal of access when a relationship ends. Assessments should also address privacy obligations and how the vendor will support investigation and recovery if a security incident occurs.
