In today's Internet era, cloud servers, as a product of the modern Internet, have brought great convenience to people. More and more people and enterprises use cloud devices, and the security of cloud services has gradually been valued by the public. The following is a detailed description content:
1. Account and password protection
Account and password protection can be said to be the first line of defense of the server system. At present, most of the attacks on the server system on the Internet start from intercepting or guessing the password. Often some people set the server password to 1234566 for the convenience of memory. On the contrary, there will be problems on the second day after the business goes online, so you must set a more complex password with multiple characters.
2. Install system patches in time
Whether it is Windows or Linux, any operating system has loopholes. Timely patching to prevent vulnerabilities from being exploited by deliberate attacks is one of the most important guarantees for server security.
3. Two-factor authentication
There can be two usage modes before a user is allowed to access a website. Therefore, in addition to the username and password, a unique verification code is also essential. This verification code may be sent to your mobile phone in the form of a text message, and then you can log in. This way, even if someone else gets your credentials, they get a unique verification code, so their login will be denied.
4. Install and configure firewall
The firewall has a very good preventive effect on illegal access, but the installation of a firewall does not mean that the server is safe. After installing the firewall, you need to properly configure the firewall according to your own network environment to achieve the best protection effect.
5. Monitoring system logs
By running the system log program, the system will record the use of the system by all users, including the latest login time, the account used, and the activities performed. By analyzing the log program report, you can know whether there is any abnormal phenomenon.
6. Port management
During business operation, close ports that are not used or not used temporarily, which can greatly improve the security of the cloud server.
7. Use genuine software
In the use of cloud servers, various software will be used, such as ssh, ftp, etc. When using these software, you must use the officially downloaded software, and do not use various cracked versions found on the Internet. The password is also in the hands of software crackers the moment you connect.
