Abstract
A malicious communication log detection device compresses first character strings representing characteristics of a communication log that is known to be malicious or benign, and second character strings obtained by coupling the first character strings with a character string representing a characteristic of a target communication log. The malicious communication log detection device calculates a score for determining whether the target communication log is malicious or benign based on a data size of the compressed first character strings and a data size of the compressed second character strings. The malicious communication log detection device determines whether the target communication log is malicious or benign based on the calculated score and a predetermined parameter.
