Question

A cloud service provider regularly updates its systems and software. Despite these efforts, a security researcher discovers a previously unknown vulnerability in an application that could expose customer data. Which type of vulnerability did the researcher find?

Answer 1

The vulnerability discovered by the security researcher is likely a **zero-day vulnerability**. A zero-day vulnerability refers to a security flaw that is unknown to the developers and has not yet been patched or disclosed to the public. Since the cloud service provider regularly updates its systems and software, this specific vulnerability had not been previously identified or addressed, making it a zero-day until it can be fixed or mitigated following its discovery.
