A financial services company discovers its internal network was breached. The investigation reveals that the initial point of entry was the network of a third-party HVAC vendor. The vendor had remote access credentials to manage the building's climate control systems, which were not properly segmented from the corporate network. This is an example of which type of vulnerability?
This scenario describes a service provider vulnerability, which is a type of supply chain vulnerability. The breach occurred because a third-party company providing a service (HVAC maintenance) was compromised, and that access was leveraged to attack the organization. This highlights the risk associated with trusted third-party vendors who have access to an organization's internal systems or data. Hardware or software vulnerabilities relate to flaws in physical products or code, and a cryptographic vulnerability would involve weaknesses in encryption algorithms or protocols.
