For example, as shown in FIG. 11 , the learner threat level setting unit 720 may define and set threat events in advance, and some minor events among these threat events - for example, viewing HTML source by right-clicking a mouse, etc. can be set to threat level 1.

The learner threat level setting unit 720 may define a threat tool in advance, and set the execution of the threat tool to the threat level 2 . For example, such a threat tool may include a screen recording program or a hacking tool.

The learner's threat level setting unit 720 may set the threat level 3 based on a history of a user's previous threat action, occurrence of a threat event, and use of a threat tool. For example, if there is a history of executing a threat event in the past and the threat event is continuously generated more than a set number of times, the threat level 3 may be set. As another example, if there is a history of previously executing a threat tool and a new threat tool different from the previous threat tool is executed, the threat level 3 may be set.

The learner threat level setting unit 720 may set the user's threat level based on the user's threat behavior. For example, the user threat level setting unit 720 may set the level of the threat performed by the user as the user's threat level.

In this way, the learner threat level setting unit 720 can perform proactive and preventive content protection by differently setting the user's threat level according to the user's threat behavior and setting different protection policies for the user. For example, when the user's threat level is high, the type of content provided may be limited, or the user's protection policy may be set to a higher policy, so that the event or threat tool blocked by the content protection browser may be set more intensely.

Meanwhile, although it has been described herein that the user threat level is directly set by the learner threat level setting unit 720 of the authentication management unit 700 , the present invention is not limited thereto. For example, the learner threat level setting unit 720 provides information on the user's threat level to the threat behavior analysis unit (not shown) of the digital lecture content protection unit 600, and the threat behavior analysis unit (not shown) is the learner It may be implemented in such a way that at least some functions of the threat level setting unit 720 are performed. To this end, the learner threat level setting unit 720 may include a threat event detection function and/or a threat tool detection function.
