Abstract: Disclosed herein are an apparatus and method for verifying a detection rule. The apparatus for verifying a detection rule includes a grammar checking unit for checking for a grammatical error in a loaded detection rule, a false-positive rate calculation unit for calculating a false-positive rate of the loaded detection rule by applying a latent Dirichlet allocation algorithm to a signature used in the detection rule, and a similarity checking unit for checking similarity between the detection rule and an existing pre-stored detection rule.
