The invention discloses a computer network security supervision system and method based on big data, and the system captures the operation habit of a user on a target file by calling the operation steps of the user before viewing the target file and the operation process of the user on processing the target file in a historical operation log of a computer. The system captures target file operation habit parameters of a current user, transmits the target file operation habit parameters to an evaluation function for calculation, evaluates target operation behaviors of the current user according to the calculation result of the evaluation function, dynamically adjusts a habit evaluation threshold value according to the evaluation result, generates an operation tolerance threshold value for limiting operation of the current user, and controls the current user to operate according to the operation tolerance threshold value. And when the operation exceeds the limit, alarming the operation exceeding the limit, proce
