In a vulnerability inspection device, an acquisition unit acquires system messages that are displayed in response to input for multiple types of service registration statuses of a user ID that is input to a login-related screen that requires input of the user ID in an account-based online service that issues the user ID. A determination unit uses the system messages that were acquired for the types to determine whether or not the login-related screen has a vulnerability regarding the leakage of user registration status.

Vulnerability inspection device, vulnerability inspection method, and vulnerability inspection program

An identification device includes processing circuitry configured to collect response information of a device by performing network scanning on a target network address group, accumulate the response information collected, compare pieces of response information having different scanning times with each other among pieces of the response information accumulated and calculate a degree of similarity between contents of responses, and identify that devices that transmit most similar pieces of response information are identical, based on the degree of similarity calculated.

Specifying device, specifying method, and specifying program

An identification apparatus includes processing circuitry configured to determine whether or not a first image and a second image are similar based on feature points extracted from each of the first image and the second image, and determine whether or not the first image and the second image are similar by comparing neighborhood graphs generated for each of the first image and the second image, the feature points being as nodes.

Identification device, identification method, and identification program

An account identification apparatus sets browsing authority for each of accounts such that browsing permission/prohibition is different for each of Web pages. Furthermore, the account identification apparatus causes a user terminal having accessed a predetermined Web site to transmit a request to each of the Web pages so as to acquire information about browsing permission/prohibition for each of the Web pages with regard to the user terminal and uses the acquired information about browsing permission/prohibition to identify an account with which the user terminal has logged in.
