BastionGuard 2.0 bundles ransomware protection, VPN, backup and phishing scanning for Linux desktops.
Jack Wallen reviews BastionGuard, a Linux security platform its developer describes as built for users who want deterministic behavior, explicit policies and visible decisions.
The suite includes Endpoint, Backup, Secure Connection and Recovery Data components, offering real-time scanning, ransomware protection, a safe-financial-institution list, USB blocking, a phishing scanner, password manager, snapshot-based backup, Samba scanner, WireGuard VPN and ClamScam email scanning.
It detected sample ransomware files every time in testing. Wallen hit a bug where quarantining one file quarantined the entire Downloads folder and the quarantine list showed nothing.
Linux kernel versions 7.0-7.2 introduce Rust support, improved NTFS drivers, and performance optimizations.
The Linux kernel receives frequent updates beyond security patches, with versions 7.0 through 7.2 delivering significant improvements. Kernel 7.0 established stable Rust support and enhanced USB-C compatibility for Apple Silicon Macs.
Version 7.1 added a modern NTFS driver, enabled Intel FRED architecture by default, and removed over 140,000 lines of legacy code. The forthcoming 7.2 release will exceed 43 million lines of code and include cache-aware CPU scheduling, USB4STREAM protocol support, and HDMI 2.1 graphics improvements.
Copy-on-write filesystems enable efficient snapshots and clones by writing changes to new blocks.
Copy-on-write (CoW) represents a fundamental shift in how Linux filesystems manage data storage. Rather than immediately overwriting old data blocks, CoW filesystems write changed information to new locations and update pointers accordingly.
This enables powerful capabilities including snapshots, cheap clones using reflinks, and efficient rollbacks without full data duplication.
Btrfs is the most accessible Linux implementation, offering subvolumes, checksums, and send/receive functionality integrated into the kernel, while OpenZFS provides more mature storage-server features. The practical advantage becomes clear when creating virtual machine copies or taking system snapshots before risky operations, as unchanged data stays shared across file versions.
Arch Linux demands constant update vigilance and manual setup, making it unsuitable for most casual users.
The author argues that Arch Linux, despite its popularity, isn't ideal for the average user due to three challenges. First, rolling-release updates require active monitoring and manual intervention that other distributions handle automatically, creating risk of breakage.
Second, upgrading neglected older machines becomes unpredictable since no version numbers track accumulated changes.
Third, Arch provides no pre-configured out-of-the-box experience, leaving users to discover and install essentials like print servers. While Arch-based options such as EndeavourOS offer better initial setups, they retain rolling-release risks. The author concludes that unless users specifically want deep system control, stable alternatives like Ubuntu or Fedora serve most people better.
Microsoft's WSL containers public preview lets developers run Linux containers natively on Windows without extra tools.
Microsoft released a public preview of WSL containers, adding a built-in Linux container CLI and an API for Windows applications to run Linux containers as part of their app logic.
The tool uses the wslc.exe binary with Docker-familiar syntax, plus a container.exe alias option. The feature benefits Linux developers required to use Windows corporate devices, offering integrated security via Microsoft Defender for Endpoint and Intune management.
Performance improvements include a new default file system claiming twice the speed for Windows file access and better networking compatibility, though these optimizations remain disabled by default during the preview.
Microsoft's WSL containers preview lets developers create and run Linux containers directly on Windows.
Microsoft released WSL containers in public preview, following its Build 2026 announcement, as a way to create, run, and manage Linux containers directly on Windows.
The feature has two main components: a CLI called wslc.exe to build and interact with Linux containers, and a WSL container API letting Windows developers use Linux containers in their app logic.
Microsoft also added a new virtiofs file system that makes Windows file access twice as fast and a consomme networking mode for better compatibility, plus Intune controls for admins. The lower-level platform changes are also being made available across tools like Docker Desktop, Podman Desktop, and Rancher Desktop, removing the need for third-party container software in many cases.
Fedora repositories now ship the stable Linux Kernel 7.1 (7.1.3), a major jump with new hardware features.
The stable Linux Kernel 7.1 (version 7.1.3) is now landing in Fedora repositories.
Intel users get the FRED feature enabled by default, helping the kernel handle system tasks more efficiently, while AMD users gain smarter power management that adjusts performance based on battery or wall-outlet use.
Developers completely rewrote the high-resolution timer core, letting systems handle complex timing tasks without slowing down overall speed. Because this is a major kernel jump, the article recommends backing up important files before updating.

The full collection at $29.50 adds ten more books covering command-line basics, modern Linux practices, security testing with Kali Linux, and container orchestration with Kubernetes.
All titles are delivered as DRM-free PDFs and ePUBs for permanent ownership. A portion of proceeds supports Code for America, a nonprofit working to improve access to government services.
Two critical Linux kernel flaws, Januscape (KVM) and GhostLock (futex), have been disclosed and patched.
Two critical Linux kernel vulnerabilities were disclosed and patched. Januscape (CVE-2026-53359) affects the KVM hypervisor, allowing attackers with guest root access to compromise host machines or disrupt other VMs, earning a $250,000 Google bug bounty.
GhostLock (CVE-2026-43499) is a privilege-escalation flaw in the kernel's futex priority-inheritance feature that went undetected for 15 years and grants limited users root access.
Both issues have been resolved. Linux administrators are urged to apply the latest kernel updates immediately.
Nushell treats data as structured tables, making it easier to filter files, processes, and JSON than traditional shells.
Nushell is a modern Linux shell that processes data as structured tables rather than plain text, eliminating the need for complex text parsing with tools like awk and grep.
Nushell works differently. Instead of passing plain text between commands, it works with structured data, where commands return tables with named columns, so you can filter and query the data directly without worrying about column positions or text formatting.
For example, ps in Nushell returns a table with columns like pid, cpu, and mem, making it easy to filter the information you need.
The article recommends Linux Mint Cinnamon over Ubuntu as the friendlier choice for most Linux newcomers in 2026.
The article recommends Linux Mint Cinnamon as the superior choice for most Linux newcomers while acknowledging Ubuntu's strengths.
Mint excels through its Windows-like interface, intuitive Software Manager, and user-friendly Update Manager that makes system maintenance feel less intimidating. Ubuntu offers advantages for those pursuing technical careers, with better support for cutting-edge hardware and alignment with professional development documentation.
The author concludes that for a normal person trying Linux on a laptop, Mint provides a kinder experience that allows gradual learning without requiring immediate system administration knowledge.
AI-assisted attack tooling is making bugs once dismissed as low severity far more exploitable and dangerous.
Vulnerabilities historically rated low severity are becoming materially more dangerous in the AI era. AI-assisted tooling lowers the effort required to discover, weaponize, and chain minor flaws into serious compromises.
This challenges traditional CVSS-driven triage, where low-scoring issues are routinely deprioritized or left unpatched for long periods. The implication for security teams is that patch prioritization and risk models need to account for how easily attackers can now automate exploitation.
Linux 7.2 lands with cache-aware load balancing, initial HDMI 2.1 FRL in AMDGPU and Rust on S/390.
Linus Torvalds released Linux kernel 7.2 with enhanced hardware support plus filesystem, networking and security improvements. Highlights include cache-aware load balancing, initial HDMI 2.1 FRL support in the AMDGPU driver, initial CRI platform support for Intel Xe, and Rust support for IBM S/390.
Other changes include a fairer GPU scheduler, large folios enabled by default for Btrfs, XFS zoned storage leaving experimental status, TDX support and Landlock UDP socket controls.
The Linux 7.3 merge window opens shortly, with the final release expected in mid-to-late October 2026.
Cross-distro Linux security needs unified tooling, risk-based prioritization and automated remediation.
Linux kernel CVEs reached 5,530 in 2025, making traditional vulnerability management approaches unsustainable.
Organizations must adopt unified cross-distro patch management and implement AI-powered risk-based assessment that goes beyond CVSS scores.
Remediation cycles should be automated with tested packages. Continuous configuration monitoring against CIS benchmarks rounds out a sustainable security program.
