Do you think you can enjoy online teaching resources and services with peace of mind after successfully logging in to the remote teaching platform? too young too simple! While distance online education provides convenience to schools, it also exposes more applications to the external network, which brings more Internet security risks. Next, the technical experts of Shanshi Netcom will detail the specific countermeasures for Internet risks in distance education from four scenarios.
Scenario 1: HeiKeGongJi received by the education intranet
To carry out distance education, the internal business system temporarily mapped to the Internet due to work needs has become the primary goal of HeiKeGongJi!
During the epidemic situation, in order to block the spread of the virus and prevent the spread of the virus, people across the country are isolated at home, and only areas of life are opened in all regions. In the face of WangLuoGongJi, enterprises also need to close unnecessary ports, keep only the necessary ports, arrange "sentinel" to register and check the legality of personnel (network RuQin behavior detection), and carry out anti-virus on the data files carried (virus filtering) ) To enter the intranet. Based on the multi-core technology and high-performance next-generation firewall, Shanshi Netcom aims to ensure user application security and combines user identification, content identification, national geographic identification and other multi-dimensional business scenario perception to provide users with rich and flexible security management and control functions.

Scenario 2: The education platform receives DDoS GongJi
Once the online education platform suffers from DDoS GongJi, the user's failure to obtain educational information will cause direct economic losses or loss of customers.
Facing the raging network GongJi, Shanshi Netcom's RuQin defense equipment blocks and protects it in a timely manner through security services such as IPS, IP reputation services, and virus filtering to block DDoS GongJi behavior and ensure business availability. At the same time, on the basis of threat detection, the intelligent next-generation firewall performs advanced threat detection on data packets. Based on behavior analysis, it helps users discover unknown network threats, locate risk hosts, and protect business and data security.

Scenario 3: Security threats from Web access
Internet business systems that were launched online during the epidemic are more vulnerable to security threats introduced through Web access.
Shanshi Netcom's web application firewall adopts multiple leading technologies such as deep proxy, application vulnerability scanning, log aggregation, and intelligent self-learning to provide comprehensive defense for web services. Provide "pre-event-in-event" full life cycle application layer security protection:
1. Pre-scanning stage protection: Through fingerprint rotation technology, a crawler model is established to identify and block advanced persistent crawlers.
2. In the event-RuQin stage protection: integrated Web missing scan function, you can quickly find system vulnerabilities, through virtual patch repair, to protect college servers from OWASP top ten risks RuQin.
3. Post-damage stage protection: Through the combination of dynamic and static driver-level anti-tampering technology, the possibility of tampering with the university website from the bottom is eliminated; once the website is broken or tampered with by HeiKe, it supports the linkage of the mobile cloud app to achieve a rapid shutdown in 3 minutes Website to avoid further losses.

Scenario 4: Security threats from the cloud
The cloud business of the distance education platform also suffers from security threats.
Cloud security is a shared responsibility model, and users need to bear the responsibility for the security of the application system and network of the teaching platform. The essence of distance education is digital assets, which are accessed through the Internet. Internet-side security risks mainly include GongJi risks such as HeiKe detection, RuQin, backdoor implantation, and DoS. Gartner counts that more than 75% of threats occur at the application layer. Today's cybersecurity world is faced with GongJi behavior for the purpose of making profits. Common GongJi means "ransomware" or "mining".

put the mountain, stone and cloud in front of the business system, and hide the business system through NAT, so HeiKe has no way to start.

matched with local detection, the built-in anti-GongJi module, RuQin defense module, and antivirus module, through the feature matching and behavior analysis, the malicious GongJi carried by the data can not be escaped. Combined with cloud detection technology, the traffic is analyzed in-depth in the cloud, and even unknown threats can be effectively detected. Finally, the effect of protecting the distance education system at every level is achieved.
