SSH is a “Secure Shell Protocol” used to connect and manage remote Linux systems securely over an unsecured network. It is very useful for system administrators to perform day-to-day tasks on the remote server. So securing an SSH server is an essential part of any system administrator.
By default, you can connect to SSH with a password or using the private key. That means, it is only a single factor authentication. So it is a good idea to implement multi-factor authentication in the SSH server to add an extra layer of security. In multi-factor authentication, you will need to provide your system user password and another password generated on a mobile device. This will significantly enhance your server’s security.
Securing your server from any kind of attacks is a key part of any web hosting provider or system administrator. You should implement a strong security policy to minimize risks and keep your data safe. There are several tips and tricks to improve your server’s security and protect it from malicious attempts to enter.
In this tutorial, we will show you some useful tips and tricks to secure your server.
In this tutorial, we will show you how to change the SSH default port in Linux, and go over why changing this default port is a good idea. IMPORTANT: Before we go any further, you should understand that this is not a solution that will prevent or deter a determined hacker to attack your SSH service. It is merely a measure to help you avoid the thousands or automated bots running all the time scanning vast ranges of IP space searching for standard SSH ports being open. Preventing a determined hacker from brute-forcing your SSH service is beyond the scope of this article.
SSH, also known as Secure Shell, is the most widely-used protocol for connecting to and managing Linux systems remotely. SSH offers strong encryption and authentication along with excellent customizability, and using SSH gives you the freedom of accessing a remote machine. You can run services and software as if you were physically using the machine, no matter where you are.
By default, SSH runs on port 22. Since this is common knowledge, this port often becomes a target for brute force attacks. Because this provides full access to your server’s OS, people with malicious intent will often target port 22 more than any other port. Changing the default SSH port will prevent automated attacks that don’t spend the time to rotate ports when targeting a Linux Server. To protect your server from a brute force attack, you should change the default SSH port to something else.
In this article, we will show you how to install the Let’s Encrypt client on your Ubuntu 20.04 VPS, issue an SSL certificate for your domain, and configure it with the Apache web server.
Let’s Encrypt is a certificate authority organization (CA) that allows anyone to obtain a free SSL certificate with simple and automated commands. In this tutorial, we will use a tool called certbot, which is an official part of EFF’s effort to encrypt the entire Internet. Thanks to this convenient tool, setting up an SSL certificate to protect your website’s visitors and improve your website’s security has never been easier. All SSL certificates provided by Let’s Encrypt can be used for production/commercial purposes without any costs or fees. Let’s begin with the installation and setup.
In this tutorial, we’ll be explaining how to install ClamAV on your Debian 9 VPS, as well as how to use it to check for and remove any malware or security vulnerabilities.
Clam AntiVirus (ClamAV) is an open-source anti-virus framework used by millions of people and companies all around the world, providing free malware protection by default for everyone. It is especially effective on email servers, as it works on just about all possible MTAs (postfix, exim, etc). It is easy to set up, customizable, and has a reliable method of virus definition updates.
ClamAV is written in C/C++ and is currently maintained by Cisco Systems. It is licensed under GNU General Public License and at the time of writing this article, the latest stable version is currently 0.101.2. Let’s get started with the installation.
In this tutorial, we will show you how to install and use the UFW firewall system on a Linux VPS running Debian 9. Security is a very important thing to consider when you run your own server.
UFW (Uncomplicated Firewall) is a simple and user-friendly front-end for managing iptables firewall rules – UFW aims to provide an easy to use interface for the user, making a secure server more accessible to more users. It is specially designed for beginner users who are unfamiliar with firewall concepts.
In this tutorial, we will guide you through the steps of installing Let’s Encrypt SSL certificate on an Ubuntu 18.04 VPS and configure it with Nginx web server.
Let’s Encrypt is a free and automated certificate authority organization. They aim to bring secure websites to all users across the web. They make installations easy and simple, and you can even set up auto-renewal so that you never have to worry about your certificate expiring. Let’s get started with the installation.
In this tutorial, we will show you how to install the Let’s Encrypt client on your CentOS 7 VPS and issue an SSL certificate for your domain.
Improving your website security through SSL encryption can increase your visitors’ trust in your website. In the past, setting up SSL encryption on a website was a complicated task. However, Let’s Encrypt is a free and open source certificate authority (CA) that allows obtaining and installing certificates through simple, automated commands. Thanks to them, setting up encryption and increasing the security of your site is made a lot easier. Let’s Encrypt provides a valid SSL certificate for your domain without any cost and can be used for production/commercial use as well.
Let’s begin with the installation – it’s a simple install, and it won’t take long at all.
In this article, we will show you how to install and configure the CSF firewall on a Debian 9 VPS, as well as go through some tips on how to use CSF.
ConfigServer Security & Firewall (CSF) is a free and advanced firewall management tool based on iptables. CSF provides a high level of security on your server and is very straightforward, making it easy to set up and install on all supported Linux distributions. We will use Debian 9 which is among the supported Linux distributions. CSF has many great features such as port scanning, SYN floods and brute force attacks for many services that can help you protect your server. One of the very nice features on CSF is that it provides a built-in web UI for managing the firewall from a web browser. This UI integration is supported by cPanel, DirectAdmin, as well as working independently on your server.
The CSF installation also comes with another service called Login Failure Daemon (LFD). LFD actually is a process that monitors the log files and sends email notifications based on the CSF configuration rules. Let’s begin with the installation.
