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...

Navigating Career Paths in Security for Professional Development

In his first column as CSO's Career Catalyst, Michael Santarcangelo outlines three essentials everyone needs to consider to make security work more than just a job. Have you ever wondered about the difference between a job and a career? I have.. As a result, I have spent the last decade considering the difference between practitioners and professionals, jobs and careers. How do you define security professional? Check out CSO blogger Dan Lohrmann's thoughts on the topic in Lohrmann on GovSpace Along the way I have been honoured to train thousands for successful careers as Certified Information System Security Professionals, founded the Security Catalyst Community and developed the Catalyst Career Compass" program. In fact, I'm working with a group of amazing people right now to re-launch the Security Catalyst Community and incorporate a guild, complete with a mentoring program (look for details in a few months). Seems a focus on professionalism and career success has always interested me. Now I have the opportunity to share ideas and strategies for career success in this column. Why me? I have cultivated a unique blend of skills and abilities: I am a professional speaker (with the capability to teach others), a published author and have over a decade of experience forged in the trenches. Over my career, I have contributed time and effort to advancing the profession through service to (ISC)2 and CompTIA. Most importantly, I am human catalyst focused on harnessing the power of people; in fact, I hold a degree in Human Ecology (go Cornell!). . For aspiring security professionals, it's essential to differentiate a job from a career. A job centers on immediate tasks, while a career prioritizes growth and expertise in security.
