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...

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...

GroupWise Urgent Advisory: Network Bug Severity and Patch Guidance

Just a reminder why we love open source the way we do. "Network managers who administer Novell's newest version of GroupWise are scrambling to fend off a bug that can severely compromise network security and e-mail systems.

Just a reminder why we love open source the way we do. "Network managers who administer Novell's newest version of GroupWise are scrambling to fend off a bug that can severely compromise network security and e-mail systems. However, Novell is not telling administrators what the bug is or how to duplicate it, saying that it wants to give customers time to patch their systems before anyone can exploit the vulnerability. "If you look at divulging details about a security issue out in public, then having customers do a firefight to get their systems updated, it's an impossible task for them to do that," says Paul Turner, director of product management at Novell. "We're taking some hits on this because we are literally asking network managers to go against their nature" and apply the patch without full knowledge of the problem. Chris O'Brien, network manager for Olivet Nazarene University in Bourbonnais, Ill., is suspicious of Novell's advice. "If the patch actually fixes a serious security problem, I have no problem putting it on as soon as possible," says O'Brien. "What does make me hesitate is the urgency combined with the secrecy of the problem. Applying a fix without knowing what it will do, makes me nervous." While most network managers don't want to ignore Novell's advice, they say Novell is wrong to not tell them the impact the bug will have on their systems.
