If you currently use Windows as your primary operating system, but feel that you are missing out on some important Linux features, it is possible to install Ubuntu on Windows through the WSL (Windows Subsystem for Linux) feature. WSL is essentially virtualization, but it allows Ubuntu to closely integrate with Windows, resulting in only a small overhead to run the additional operating system, and the ability to natively access the entire Windows file system within Ubuntu.

How to install Arch Linux alongside Ubuntu (Dual Boot)
Arch Linux and Ubuntu are two extremely popular Linux distributions. While they naturally have a lot of functional overlap, their core principles, user friendliness, and native features are very different. Ubuntu is easy to use, while Arch Linux is more customizable. Rather than trying to decide between the two, it is possible to configure a dual boot system so that you can boot into whichever operating system you feel like using.
How to install Arch Linux alongside Windows 11 (Dual Boot)
Arch Linux is a robust operating system often chosen by power users and IT professionals. While there is no doubt that it is an extremely powerful OS, the need to use other systems can also arise for users that are required to use a variety of applications and ecosystems that Arch Linux can’t always easily accommodate. This is when a dual boot system that runs both Arch Linux and Windows 11 proves useful.
How to install Kali alongside Windows 11 (Dual Boot)
Security professionals often need to use a variety of operating systems to perform their tasks. Dual booting Kali Linux and Windows 11 grants users the ability to switch back and forth between systems, depending on the work that needs done. Being able to access both Kali and Windows from the same computer gives a lot of flexibility for taking advantage of both system’s abilities.
How to install Ubuntu alongside Windows 11 (Dual Boot)
If you want to be able to run both Ubuntu Linux and Windows 11 on your PC, one option is to implement a dual boot configuration. This will give you the best of both worlds by allowing you to boot into either Ubuntu or Windows 11 whenever you turn on your computer. Having access to both operating systems is a powerful option in which you can take advantage of both system’s abilities.
Securing Linux with TCP Wrappers: A Quick How-To
Enhancing a Linux system’s security with TCP wrappers essentially involves editing two files. The first is the hosts.allow file, which allows administrators to specify which hosts or networks can access the system. The other file is hosts.deny, which explicitly states all of the hosts or networks that will be prevented from accessing the system. The files also allow us to specify which services should be accessible or protected.
Using Logwatch for Basic Security Monitoring on Linux
Linux systems write a lot of information to log files. Typically, each system service you install will have its own log file or set of log files. This is in addition to all of the default logs that get generated, such as those from dmesg, boot log, the package manager log, etc. Inside of these files, it is common to see thousands of entries over a very small span of time.
Container Security Best Practices: Securing Docker
When it comes to containerization, Docker has easily become the most widely adopted technology. As businesses and users in the industry look toward using containers to cut costs, scale services, and steamline implementation of numerous applications, an important aspect that should not be overlooked is the security of Docker. Docker is commonly lauded as being more secure than traditional deployments, and, while true, we still must be aware of potential security flaws to prevent the exploitation of such a powerful tool.
Advanced Firewall Management with nftables: Transitioning from iptables
nftables is the successor to iptables on Linux systems, and has since become the default firewall. If you have not yet transitioned over to nftables, you are missing out on improved performance, easier command syntax, and an overall simpler way to manage firewall rules. In this tutorial, you will learn how to transition to nftables from iptables commands. To do so, we must become familiar with how nftables differs from iptables from a functional standpoint, as well as the new command syntax for configuring rules. The iptables command can still be used on most systems, but it is now linked to a tool that translates the input to equivalent nftables rules, before handing the configuration off to nftables for enforcement.
How to check Raspberry Pi Java versions
Java can be an important component of a Raspberry Pi system for users that need to run programs that have been compiled with Java, or for developers that wish to code applications in Java. For those working with raspberry pi java, Since Java is constantly being developed, new versions are released and we may find that our Raspberry Pi needs to update to the latest version available, or download an older version for increased stability and legacy features. In this situation, we can install multiple versions of Java and then switch between them as needed.
Automating Security Audits with Lynis on Linux Systems
A paramount aspect of Linux administration is system security. Once we have a certain number of software packages, settings, and user accounts on our system, the task of securing every facet of the system can quickly become overwhelming. This is why it is important to employ a script such as Lynis, which will check tons of different areas of the system for security flaws or potential attack surfaces that malicious programs or users may be able to take advantage of.
Setting Up a Linux Intrusion Detection System with AIDE
An intrusion detection system (IDS) is an important security tool for system administrators. Its purpose is to notify us whenever it detects that a potential intrusion has occurred. When an attacker compromises a system, one of the first things they will usually do is attempt to change file permissions, attempt to escalate to the root user account, or start modifying system files. The IDS is configured to monitor for these changes and make us aware of them if they occur.
