In the realm of Linux, security is a top priority, and one of the innovative tools for enhancing security is firejail. This sandboxing tool limits the scope of program operations using Linux namespaces and seccomp-bpf, which stands for Secure Computing Mode with Berkeley Packet Filter. Primarily, it's used to restrict the system calls that a process can execute. In this blog, we will explore how firejail can be used to restrict a script's access to specific syscalls. Q: Can you explain what firejail is and why it's useful? A: Firejail is a sandboxing tool that uses Linux namespaces and seccomp technology to restrict the running environment of untrusted applications.

Linux systems are renowned for their robust security features, making them a top choice for server environments and security-conscious users. To further enhance their security posture, Linux administrators and users can leverage various security auditing tools designed to detect vulnerabilities, monitor unauthorized activities, and enforce security policies. In this blog post, we will explore some of the most effective security auditing tools available for Linux systems, and provide installation instructions using different package managers like apt (for Debian-based systems), dnf (for Fedora and RHEL-based systems), and zypper (for openSUSE systems).

In the world of Linux, system security is a priority for admins and users alike. While Linux is often praised for its robust security model, no system is infallible. Hardening your Linux system minimises the risk of attackers exploiting your machine. In this blog post, we will cover key security best practices and operational steps using Bash commands, tailored for various Linux package managers like apt (Debian/Ubuntu), dnf (Fedora), and zypper (openSUSE). One of the simplest and most effective ways to secure your Linux system is to keep it updated. Updates often include patches for security vulnerabilities, so regular updates can prevent potential exploits.

When operating a Linux system, whether for personal use or within a professional environment, security should always be a top priority. Linux is often touted for its robust security features, and while it indeed provides a strong foundation, the system's security is significantly influenced by the configuration and maintenance practices of its users. In this comprehensive guide, we'll explore essential security tips for Linux systems, including insights on managing packages securely with popular package managers like apt, dnf, and zypper. One of the most crucial steps in maintaining system security is ensuring that your system is up-to-date.
