The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Server SecurityPrice Tag 1open-source Linux administration

Cron has existed in Unix and Linux environments for decades, handling backups, cleanup scripts, patching jobs, log rotation, monitoring tasks, and other maintenance work that administrators do not want to run manually. Most Linux servers rely on it constantly, which is exactly why attackers continue abusing it for persistence after a system has already been compromised. . Persistence through cron is not complicated. Attackers do not need a rootkit or advanced malware framework to maintain...

A major internal repository breach at GitHub has exposed a critical and overlooked blind spot in Linux supply chain security. Kernel exploits, exposed SSH services, weak firewall rules, and vulnerable daemons dominated the Linux threat model for years, and in many environments, they still matter. But recent supply-chain incidents involving GitHub ecosystems, npm packages, and malicious developer tooling point somewhere else entirely: the developer workstation. . The breach matters because...

Linux administrators often face an ugly choice in the cloud: prioritize convenience and cost-efficiency by sharing infrastructure, or sacrifice those benefits for the sake of total isolation. Most modern Linux workloads don't live on their own private servers anymore. They live in shared environments like Kubernetes clusters, where multiple teams and services run side-by-side. It sounds efficient, and it usually is. . But cloud isolation isn't as ironclad as it looks on the diagram. If you...

Managed Extended Detection and Response (MXDR) has become one of the most sought-after security services in the enterprise market — and with good reason. It promises the holy grail: broad visibility across endpoints, network, cloud, email, and identity, combined with the 24/7 human expertise most organizations simply cannot build in-house. . However, the rapid growth of the market has produced a wide range of providers whose capabilities vary considerably beneath the surface. Choosing the...

Explore Godzilla Crypto Tutorial: 509 Slides on Encryption Techniques

This page contains my godzilla crypto tutorial, totalling 509 slides in 8 parts, of which the first 7 are the tutorial itself and the 8th is extra material which covers crypto politics. Part 8 isn't officially part of the technical tutorial itself. The tutorial is done at a reasonably high level, there are about two dozen books which cover things like DES encryption done at the bit-flipping level so I haven't bothered going down to this level. Instead I cover encryption protocols, weaknesses, applications, and other crypto security-related information. Since the slides are accompanying material for a proper tutorial, there's a lot of extra context which isn't available just by reading the slides. Bear in mind that some of the claims and comments on the slides need to be taken in the context of the full tutorial. Accompanying the slides are about 150 images, unfortunately I can't make these available for copyright reasons. . The tutorial is formatted so that two slides fit one page, which means you'll burn out about 260 pages of paper printing them all out (half that if you print double-sided). To view the tutorial you'll need a copy of the free Adobe Acrobat Reader software. Note that most of the diagrams (and there are quite a few of them) will look a lot better on paper than on screen. The gv viewer (a replacement for ghostview) displays the slides better than the Acrobat Reader, especially with antialiasing enabled. The output was generated from Powerpoint slides, unfortunately Powerpoint converts the text colours of embedded tables into a very hard-to-read light grey, ignoring the actual text colouring set for the table. There doesn't appear to be any way to fix this problem. The link for this article located at Peter Gutman is no longer available. . The tutorial is formatted so that two slides fit one page, which means you'll burn out about 260 pag. godzilla, crypto, tutorial, totalling, slides, parts, which, first. . LinuxSecurity.com Team
