Introduction Libvirt is an open-source tool used for managing virtual machines on Linux systems. One of the challenges with virtualization is ensuring that the host system and virtual machines are secure. SELinux, or Security-Enhanced Linux, is a security module that can be used to add an additional layer of security to both the host system and virtual machines. In this article, we will explore how SELinux can be used to protect the host and virtual machines. [Read More]

Rootkits on Linux: A Threat to System Security A rootkit is a type of malicious software that allows an attacker to gain privileged access to a computer system. This access can be used to steal sensitive information, install additional malware, or carry out other malicious activities. Rootkits on Linux can be particularly dangerous, as they can go undetected for long periods of time and allow an attacker to gain complete control over the system. [Read More]

SELinux: Enhancing System Security SELinux stands for Security-Enhanced Linux, which is a security module implemented in the Linux kernel. It provides an additional layer of security by enforcing mandatory access control policies on top of the traditional discretionary access control mechanisms provided by the Linux kernel. SELinux was developed by the National Security Agency (NSA) and external contributors in collaboration with Red Hat and has been integrated into various Linux distributions, including Red Hat Enterprise Linux, Rocky Linux, AlmaLinux, and Fedora.

Introduction The Linux Kernel Virtual Machine (KVM) is a hypervisor that allows multiple virtual machines to run on a single Linux host machine. KVM is an open-source technology that is integrated into the Linux kernel and supports various hardware platforms, including x86, ARM, and PowerPC. In this article, we will discuss the key features and benefits of KVM, how it works, and how to install and configure KVM on a Linux machine. [Read More]
