Type 1 Error (False Positive): In cybersecurity, a Type 1 error occurs when benign activity is incorrectly identified as malicious, such as mistakenly flagging legitimate network traffic as a threat. This can result in unnecessary actions and reduce trust in security systems due to excessive alerts.

Type 1 hypervisor: A type of hypervisor that runs directly on a physical host machine's hardware, allowing multiple operating systems to be run on the same physical server. It is used in server virtualization and cloud computing environments. Examples include VMware ESXi and Microsoft Hyper-V.

Type 2 authentication factor: A type of authentication factor that is based on something a user has, such as a security token or a smart card. It is used in information security to verify the identity of a user. Examples include a security token, a smart card, or a USB key.

Type 2 Error: A statistical error that occurs when a null hypothesis is not rejected, even though it is false. This is also known as a false negative. It is used in the same contexts as Type 1 errors. Examples include failing to reject a faulty medical device or assuming there is no relationship between two variables when there actually is.

Type 2 hypervisor: A type of hypervisor that runs within a host operating system, allowing multiple virtual machines to be run on the same physical host. It is used in desktop virtualization and personal cloud computing environments. Examples include VMware Workstation and Oracle VirtualBox.

Type 3 authentication factor: A type of authentication factor that is based on something a user is, such as a fingerprint or a facial recognition scan. It is used in information security to verify the identity of a user. Examples include a fingerprint scan, a facial recognition scan, or a voice recognition scan. This is also known as biometric or something you are authentication.
