I'm glad to be back to a share of new things and learn about technology without limits to all of you. Did, with our much read and tried a variety of things, we will be rich with knowledge. Primarily to understand the working field. I like to learn something as we learn and better understand the hobby us.It was easy if we want and love. Then on this pleasant, I would take the time to share discussion on Linux. From what we've learned earlier in many tutorials, Linux is a name under the auspices of the Unix operating system. But we will not discuss what was Linux.
We will focus on new things to enrich their knowledge, for that I deliberately made the tutorial how to protect your Linux VPS. Why do we have to do away to protect it? That's because we do not want other things happening in the system that we build and create jobs will increase twice.
VPS is a virtual server in the form that we can install on its own operating system, such as Linux earlier example. The advantages of using VPS feels like a Dedicated Server. VPS advantages compared to shared hosting is, with VPS you get a more definitive resource, either CPU, memory, and space. So do not be disturbed if there is a problem on the website of your neighbors. Also, gain root access so that more flexibility in customizing the server as needed.
Let's start! First steps we have to do is keep the foundation of Linux VPS in order to remain safe. VPS itself actually have administrator privileges that can be used as a manager server with the full authority of the process. But this is such an option with comfort provided and truly capable of performing tasks quickly and became a solution. But it also could be a friendly hacker, and all Linux VPS can be in danger of attacks on data and makes communication through the server to be hampered.
Well, to avoid this then the client-server providers must find a definite effort to protect VPS Linux safe from hackers. Actually, there are quite a lot of ways to protect your server in order to remain secure from rootkits and malware. But one of the most efficient tools of the solution is with rootkit hunter. Here I will explain the process of installation of the anti-rootkit program with options that can be changed with the root login directly through SSH.
Step two is not to provide a password, although a password and a personal email still don't give up. It would be very dangerous if the password contained in the VPS system. So, to keep the Linux VPS to keep it secure the necessary passwords completely safe. You have to make it and create a password that is unique and hard to solve the hackers.
Such methods are aggressive in the dictionary attack is a fairly complete key cryptographic which can create a password and then uncovered the stolen data with very significant. For we have to think hard to create strong passwords and change passwords complex routine as described earlier. This is also true for newbies and it is important for them to know.
Step three is to strengthen the walls thoroughly both inside and outside. To protect your computer and the server of the data exchange is not desirable, then we need a virtual filter in the form of a firewall. Quite easy because the settings can also be changed to adjust the needs of each and this is the most simple firewall with sufficient protection. And do not worry because the firewall is easy to install, not all free. If you want free, perhaps CSF is one with a utility measurable than others.
Please note by beginners, easy to spread rapidly Linux and open source VPS perfect. And to have the strength to full scale and the ability to adapt while improving the protection of Linux VPS and keep the business to remain successful.
Step four is to create an SSH-key login authentication with a fairly flexible and methods are quite different. As an option is quite popular among them. If you want the most natural may be contained in the password authentication, this is actually not too safe for the majority of users who liked it. Login password may provide the potential for an intruder to guess your password combination.
However, on the other hand actually, SSH key can login creates a secure public key as the identification of the user, and can be disseminated without any problems. But unfortunately, this key cannot be used for anything else besides identifying users when they log in person. Their private key does still have them hidden and used only for public key attached. Well, then we can also add additional passphrase long as security keys. But now I'm not going to tell about it now and here. You will find out how to set up SSH-Key the same login.
Step five we can strengthen security by using secure shell (SSH) protocol that has been encrypted securely. In addition, we can also use Telnet as Putty SSH server connections and can be downloaded easily.
Actually, there are many ways to strengthen the security of Linux VPS us of the dangers of hackers who threaten and help facilitate users, but the administrator does have to think and choose what kind of security that would strengthen the walls of your server. Well, this tutorial helps us to find a strong and reliable security for Linux VPS. Although not all are available for free entitle, but do not worry about the security of their brave stake. The important thing is how we manage security strategy and depending on the services that we run on the server.
You are fortunate enough to have come to seek out and study this tutorial, we are happy to help you guide the steps for a strong security for servers and provide the best experience. Trying to overcome the problem of security is threatened and take the best step. Don't worry to always connect to our website if you encounter problems when trying to start, because we have a lot of answers that could help solve the problem for the security of your Linux VPS.
