If neither the client nor the server implements SSL encryption technology, it is very easy for information to be stolen by intermediate attackers during the propagation process, thus causing serious risks to data security. For this reason, corresponding measures should be taken urgently to effectively ensure the security of sensitive data. You can refer to the following methods to operate.
1. Upgrade and transform the server system
You can give priority to upgrading and optimizing the server system, or supplement all the necessary components to ensure that it can smoothly support the latest SSL protocols.
2. Deploy SSL certificate
You can purchase and deploy SSL certificates issued by prestigious certification centers, and install them in the server to achieve this function.
3. Turn on the SSL protocol
You also need to make sure that the selected web server actually supports the SSL protocol. For example, if you are using the Apache web server, you need to enable the mod_ssl module to achieve this purpose.
4. Flexible negotiation of supported encryption
In such a situation, in order to optimize the experience, the server can even actively downgrade to a relatively old SSL version. This in turn provides users with more optional encryption methods.
5. Appropriately adjust the encryption strategy
In addition, we can also reduce the encryption security level so that more types of SSL protocol versions and encryption methods can be supported. This can not only ensure network security, but also give full play to the potential effectiveness of more options. It is really a best-of-two strategy.
