Abstract: In a network monitoring system according, first, a data acquisition section acquires a plurality of packets flowing on a network. Then, a data analysis section acquires action explanation information for explaining a single action from the plural packets acquired by the data acquisition section. Then, a display-information generation section displays the single action on the network on the single screen based on the action explanation information acquired by this data analysis section.

Abstract: A password strength checking method includes operations of inputting a password to be checked, generating a plaintext password candidate according to the same generation procedure as that used by a password guessing tool, determining whether or not the inputted password and the generated password candidate match each other, directing generation of the next password candidate when the match is not determined, determining strength of the inputted password based on the number of the generated password candidates when the match is determined, and outputting information of the determined password strength.

Abstract: A password input table creating method for creating a password input table referred to when inputting a password in a computer includes a step of displaying on a display a creation table having multiple entry fields each of which is to be an input area for one character, a step of entering, in the entry field of the creation table, each of characters composing a password to be inputted into the computer through an interactive process, a step of creating a password input table by randomly entering possible characters to be used for a password in entry fields of the creation table which have no character inputted therein, and a step of outputting the created password input table.
