There have many ways that have suggested that can be used to improve Linux server security. This article contains ways that, if implemented, will guarantee you that nobody can get unauthorized access to this machine. At this point what you need to do is to sit take a short while and read the rest of this piece in order to be informed about the same.
The most basic way is to set strong passwords. This is a very common way that most people are familiar with. However, not all of these people have the idea of how to make their password phrases to be powerful. Basically, a strong pass phrase will contain a mixture of characters. In addition to the characters, there is also the inclusion of numbers. One should take note that both upper and lower case letters together with special signs are the ones that compose a strong password.
In all Linux platforms, the root user is the one who has all the rights in the system. In most cases, it is only the administrator who has this access. To avoid any possibility of unwanted changes, root logging should be disabled. Doing so ensures that the server remains with the initials settings. Often, such configurations are hard to attack. During this process, the security of this equipment is hardened.
All the information and files that are transferred from and to the server by the administrator must be encrypted. The file and document encryption makes it hard for a hacker to get access into the system. As such, it constitutes the top ways of hardening the security level of the Linux server.
As the administrator, you should only assign users limited rights. For instance you can specify that they only have the ability to read and right documents but cannot delete them from a machine that is connected to this computer. All the changes that should be made to the network can only be implemented by the administrator. As a result, this method will ensure that this equipment remains secure for the longest period possible.
Ensuring that there is physical security of this equipment is very important. It must not be located where it can be easily accessed by many people. It should be in room that has strong walls and a steel door. The combination of these two factors contributes in discouraging someone who may want to tamper with the system.
The first step to take after you have bought the machine is to analyze it. This will enable you be in a position to know which installed programs are needed and which are not very essential. After that, go ahead and remove those that are not very important. The reason for doing so is to reduce the number of software in the machine. The less the software, the more secure the server is.
Updates are usually released after a given period of time. To enhance Linux server security, make sure that your software is updated. The process of updating does not take much time. Newly defined methods of preventing intrusion are usually found in the new tools.
