Linux web server is by far the most wide-ranging and complete solution provider of web hosting around the world. When compared to Windows server, it delivers superior flexibility at very low cost, that’s what makes it a common choice of hosting. Linux is perhaps the most secure platform. However, just like other there are evident dodges in Linux too. So the question arises now, how to configure Linux server? Here are things you should perform to configure Linux server for the highest level of security.
1. Automatic security updates should be switched on – Enable the automatic installation or configuration of security updates via a cron script. Don’t worry about issues related to compatibility, old system settings are constantly kept in the archives you can easily go back.
2. RSA signed authorization keys must be used– Using password authentication to login to the server has obvious loopholes. A skilled hacker can break the password using tricky software’s or with intellectual guesses. However, RSA signed authorization keys are much more secured than password authentication methods. It is one of the important steps in Linux server configuration.
3. You should delete the test accounts when the need is over – It’s one of the most common security errors. During the development stage of any software, it is verified with the use of test accounts, and the passwords used are very common. Quite frequently, the client forgets to get rid of these accounts prior to the installation of software on the server. You will face security issues that cannot be prevented by the robust security and configured Linux server.
4. Disable errors- PHP is the most common language used in the Linux server. A chief drawback of PHP is that if a website displays an error message, then it displays very sensitive information that can be used to attack on the server. And this can be very deadly for the data. So we need to disable the error messages at any cost.
These are some of the common and important mistakes that are missed by the server administrator during the Linux server configuration.
