With the popularization of the Internet and the acceleration of digitalization, cyber attacks occur frequently, posing a serious threat to the normal operation of enterprises and the personal information of customers. To meet this challenge, many businesses are turning to CDN (Content Delivery Network) to help improve performance and security. Among them, free domestic CDN is favored because of its advantages such as cost-effectiveness and wide coverage. However, while enterprises enjoy the convenience of free CDN, they also need to be wary of the potential risk of cyberattacks. This article will explain how to use free domestic CDN to effectively prevent cyber attacks on customers, ensure the security of customer data and the stability of corporate reputation.
1. Understand the types and hazards of cyber attacks.
Before taking any precautions, businesses must have an understanding of the common types of cyberattacks and their harms. Common types of cyber attacks include DDoS attacks, CC attacks, IP attacks, etc., which can lead to paralysis, data breaches, server resource exhaustion, and other problems. Once a cyber attack occurs, it will not only cause economic losses to enterprises, but also immeasurable losses to customers, such as personal information leakage, property losses, etc. Therefore, enterprises must pay close attention to the prevention of cyber attacks.
2. Choose the right free CDN service provider.
Choosing a reliable and efficient free CDN service provider is key to preventing cyberattacks on customers. When choosing a CDN service provider, enterprises should focus on the following aspects:

4.Customer Service & Technical Support: Choose a service provider that provides timely, professional customer service and technical support so that issues can be resolved quickly when encountered.
3. Configure security protection measures.
After selecting a suitable free CDN service provider, enterprises need to configure appropriate security protection measures based on their own needs. Here are some suggested actions:

8.Establish an emergency response mechanism: Formulate a detailed emergency response plan, clarify the process and responsible person for responding to various cyber attack incidents, and ensure that you can respond quickly and take effective measures in the event of an attack.
9.Cooperate to establish security alliances: Cooperate with enterprises in the same industry to establish security alliances, share security information and defense experience, and jointly respond to cyber attack threats.
