Abstract: Disclosed herein are an apparatus for determining a device group to be isolated using similarity of features between devices and a method using the apparatus. The method includes generating device groups in consideration of respective features of all devices, generating a security threat device group based on devices in which a security threat has occurred, among all of the devices, calculating the cosine similarity between the security threat device group and all of the device groups, and determining at least one device group to be isolated, among all of the device groups, in consideration of the cosine similarity.
