After reading the first three articles of the "Shan Shi Wang Ke Distance Education Security Solution Broadcasting" article, we have solved the three major security problems that must be solved in distance education, and the network security fortifications of distance education have become solid.
However, the fortress is often broken from within. Have you considered that the threat may also come from within the educational institution?
Internal leak, time bomb for distance education
Distance education and training institutions have invested a lot of manpower and financial resources in the design and production of courses. Due to the weak security awareness of internal teachers, operation and maintenance personnel, and students, they unintentionally leaked confidential information such as courseware, lecture videos, and test papers to the Internet. There will be serious consequences. What's more, in order to obtain unjust money, deliberately leaking the core assets of distance education institutions to competitors will cause serious economic losses to the institutions.
In view of the potential leakage of teaching assets, many distance education institutions choose to deploy data encryption software to achieve the purpose of protecting business information, but once the files are encrypted, the original structure of the data will be changed in principle, and the integrity of the data cannot be guaranteed; And encryption technology may cause the system blue screen or encrypted files to be damaged, increasing operation and maintenance costs; at the same time, encryption products have a strong dependence on the terminal operating system and application software environment, such as operating system replacement, software upgrades, etc. The effect has a certain impact.
Mountain Stone Network Distance Education Teaching Asset Protection Solution
In view of the disadvantages of data encryption technology, Shanshi Netcom's data leakage protection system based on content recognition technology can be used to send out terminal operations of employees and students in remote education institutions (such as U disk copy, email outbound, and network disk upload) Etc.) to conduct audits or blockades to prevent the leakage of confidential materials such as courseware, lecture videos, and question papers. Shanshi Netcom's data leakage protection system can classify and classify data by content, and can be extended to the prevention and control of data through recognition, so as to achieve active protection, instead of focusing on a whole file like data encryption technology, it cannot be done Active leak protection. More importantly, this system will not cause damage to the content of the information. While preventing data leakage, it will not affect the normal use of internal teachers and students.
As shown in the figure below, first mount a mountain stone network data leakage protection system next to the network exit of the distance education institution as a unified data asset management platform, and then let teachers, students, and institutional employees install the mountain stone network department on their own terminals. The data leakage prevention plug-in generates a unique identification code. Only users with an account, password, and unique identification code can successfully log in and access teaching materials such as courseware, lecture videos, and test papers.

Application Scenarios of Mountain Stone Network Technology Distance Education Teaching Asset Protection Solution
After the remote education institution successfully deploys the Shanshi Netcom data leakage protection system, it can greatly reduce the probability of leakage of the institution's teaching assets. Specific application scenarios are listed as follows:
Scenario 1: In the online education business, students can use their computer equipment to access resources such as teaching videos and materials. There are intentional or unintentional data leakage during the use process, such as intentionally recording online videos for non-learning purposes. This way of leakage can be marked by adding screen watermarks, etc. Once the leakage occurs, the source can be traced.
Scenario 2: Students and teachers may intentionally or unintentionally leak courseware, lecture videos, and question papers that already exist on their computers through emails, network disks, and nails. In order to prevent such incidents, the leakage of relevant core teaching assets can be blocked through preset strategies.
Scenario 3: For the purpose of commercial interests, employees within a distance education institution may intentionally leak the teaching materials of the institution through U disk, printing, Bluetooth, etc. In order to prevent such incidents from happening, relevant leaks can be blocked in a timely manner through pre-set strategies, and detailed audit records should be made, so that the employee's computer's IP, MAC address, specific time, specific content of the data to be leaked and other information.
Shanshi Netcom's distance education teaching asset protection solution provides comprehensive security management from the perspective of users, data, and networks. It provides effective prevention and control of the out-of-regulation issuance of teaching assets such as courseware, lecture videos, and question papers in remote education institutions. After the source audit.
In the next issue, we will give you a detailed introduction to "how to eliminate the leakage of personal privacy information of teachers, students and parents stored in the internal database server of remote education institutions", so stay tuned!
