＂Online class invasion＂ happens from time to time. How to create a safe online class space？

　　Beijing, Nov. 6 (Reporter Li Yang Qihe, Headquarters) Nowadays, online meetings and online teaching have become one of our familiar and commonly used ways of working and learning. At the same time, there has been a behavior of "online class blasting", which destroys the order of online classes through network intrusion. After the participants in the online class leaked the meeting number and password of the online class, the troublemakers entered the online class and maliciously disturbed the teaching order through extreme methods such as forcibly dominating the screen and even insulting.

　　In order to effectively strengthen the governance of cyber violence, further compact the main responsibility of the website platform, and improve the long-term working mechanism, the Central Network Information Office recently issued the Notice on Effectively Strengthening the Governance of Cyber Violence, which made requirements for establishing and improving the early warning and prevention mechanism of cyber violence, strengthening the protection of cyber violence parties, and preventing the spread of cyber violence information. How to treat the behavior of "online class blasting"?

　　"Online class blasting" usually refers to the act of entering an online class classroom, playing music and videos unrelated to the class, and abusing students and teachers in order to disturb the teaching order. This behavior is called "blasting", and intruders call themselves "blasters".

　　Usually, these people will have a special "online class blasting group". Only students need to join the group to publish the online class meeting number and password, and intruders can enter the classroom and disturb the normal online class teaching. Jing Hao Yu of Touch Music Network has made an in-depth investigation on "online class blasting" and "blaster". From what he learned, the motive of "online class blasting" is mainly the mischief of minors, and few people make profits from it. Jing Hao Yu said: "He may not be a student, but he may have dropped out of school, or he may be attending school, or even doing well. He doesn’t have to vent his anger, maybe he just has a mischievous and malicious mentality, and he doesn’t really have any anger. I observed that they don’t charge. I asked the owner this question, how much money can help me blow up a section, and he said no money, just fun. Most of the people I have seen are really free. They send an online class meeting number to different groups, and there may be several people blasting the same online class. There is no interest in this. I have never seen this process, and no one has given money. "

　　Jing Hao Yu said that if there are more lists in active groups, the "blasters" will also share the real-time progress. "They will continue to go there to interact in the process of blasting online classes, such as putting a battle song. After the end, they will communicate in the group, which teacher is crying or something, and they will send their recorded videos to the group as a trophy. " He said.

　　After the "online class explosion" caused social concern, some groups were directly dissolved, and some groups would discuss whether to continue. Jing Hao Yu said: "Some people quarreled in it and said that they would release it. Some people also realized the seriousness of this matter. On the whole, they still converged a lot, and the impact was not as great as we thought, because their information was very lagging. It’s hard to say whether these minors have mobile phones if they don’t take online classes. If you have a mobile phone, you don’t necessarily read serious news reports. They may not even know that this social event has happened. "

　　Since September this year, the situation of "online class invasion" has been exposed one after another. In order to cope with the "invasion of online classes", Tencent Conference urgently developed the function of "one-click suspension of participants’ activities". When the blaster invades the meeting, the teacher can immediately regain control through this function. One-click "pause the participants’ activities" can control the venue and repel the intruders who maliciously join the meeting.

　　Nail has also added a button in the "video conference" module, and the sponsor has the right to decide whether outsiders can enter the video conference. But from the actual situation, some teachers may not be very familiar with the specific functions of buttons.

　　In the view of Yu Kui, a 360 mobile phone security expert, when encountering "online class intrusion", the intruder’s speech function can be restricted through the management of conference software or batch control. Users should also fully learn and understand the functions of the conference before using it. Yu Kui said: "It is suggested to strengthen the ability of online meetings in authentication, management and training to ensure the stable development of online meetings. Strengthen the authentication mechanism of the meeting, and increase the authentication mechanism between the meeting party and the participants, for example, increase the secondary authentication of the participants, and the participants need to be confirmed twice to join the club. Strengthen the meeting management mechanism and increase the rapid management and control methods of the meeting, for example, invite participants out of the meeting in batches. (At the same time) provide an easy-to-understand tutorial for meeting use. "

　　Recently, the "Notice on Effectively Strengthening the Governance of Cyberviolence" issued by the Central Network Information Office pointed out that measures such as closing accounts should be taken in accordance with the law for accounts that are initial, frequent, and incited to publish cyberviolence information. If the circumstances are particularly serious, the whole network is prohibited from registering new accounts. Involving illegal crimes, the transfer of relevant departments shall be investigated for legal responsibility according to law.

　　Cui Xiangqian, a professor at the Central Plains Public Security Research Center, believes that invading an open classroom may constitute a crime of seeking trouble and insulting. If it is entered by blasting, it may constitute an offence. Network security education needs to attract everyone’s attention. Cui Xiangqian said: "This kind of case is best to prevent, and the platform improves the safety protection technology. In addition, teachers and students should jointly prevent it and cannot be open indefinitely. First of all, cybersecurity education should be strengthened, and we should strengthen it in the context of national security. He does not know that this situation is illegal. Of course, incidents like this may be students’ pranks, or even students’ own online pranks. In this case, it is mainly a disturbance problem. We must rise to the perspective of national security. Cyber security is an important part of national security and should be entered in primary and secondary schools. " (Yang Guangwang)
