The marketing department setting up its own project management software without informing the appropriate departments is an example of Shadow IT. Shadow IT refers to the use of IT systems, devices, software, applications, and services without explicit approval from the IT department.
* Shadow IT: Involves the use of unauthorized systems and applications within an organization, which can lead to security risks and compliance issues.
* Insider threat: Refers to threats from individuals within the organization who may intentionally cause harm or misuse their access, but this scenario is more about unauthorized use rather than malicious intent.
* Data exfiltration: Involves unauthorized transfer of data out of the organization, which is not the main issue in this scenario.
* Service disruption: Refers to interruptions in service availability, which is not directly related to the marketing department's actions.
