system security Linux network 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 Securityopen-source Linux administration
open-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...

Vendors/Productssecurity breach linux
security breach linux 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...

Security Trends access control multi-tenant
access control multi-tenant 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...

Vendors/Productsincident response cloud security
incident response cloud security 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...

security practicescryptographybook reviewExploring Bruce Schneier's Cryptography Engineering for Practitioners
Bruce Schneier has updated Applied Cryptography. I have a new book, sort of. Cryptography Engineering is really the second edition of Practical Cryptography. Niels Ferguson and I wrote Practical Cryptography in 2003. Tadayoshi Kohno did most of the update work. Cryptography Engineering is a techie book; it's for practitioners who are implementing cryptography or for people who want to learn more about the nitty-gritty of how cryptography works and what the implementation pitfalls are. If you've already bought Practical Cryptography, there's no need to upgrade unless you're actually using it. The link for this article located at Bruce Schneier is no longer available. .

network securitysecurity practicesCiscoDesigning Network Security Book Review: A Practical Guide by Merike Kaeo
This is a very good book. It provides a good foundation of basic universal security practice and then goes into detail on how to implement network security using Cisco hardware and software. No single aspect is covered in exceptional depth- the book is meant to give a little information on the whole range of security rather than mastering any one area of network security. . . .. This is a very good book. It provides a good foundation of basic universal security practice and then goes into detail on how to implement network security using Cisco hardware and software. No single aspect is covered in exceptional depth- the book is meant to give a little information on the whole range of security rather than mastering any one area of network security. Kaeo brings a decade of knowledge and experience to the subject and the writing is relatively clear and concise. Merike Kaeo has been a network security professional with Cisco Systems, Inc for over 10 years. As a CCIE and a member of IEEE and IETF Kaeo has a tremendous amount of knowledge and experience to share on the subject. The first of the book provide an overview of the core "Security Fundamentals". Each chapter delves a little deeper as the author talks about various aspects of network security including encryption, authentication, PKI, wireless security and more. Beyond that Kaeo discusses the prevailing environment and what sorts of threats exist currently. Aimed more at infosec managers than administrators it provides a good look at common attack methods and things to consider when implementing network security. These first two sections combined also provide a wealth of information to help those aspiring to pass the CISSP or other security certification exams.

I've been wanting to get my hands on this book ever since I got the press release announcing this latest addition to the "Hacks Series". When the O'Reilly folks sent us a couple of copies, I've already had a book or two in my queue, but as I'm a fan of Flickenger's work (both the writing and the actual WiFi creations), it was a natural choice that "Wireless Hacks" received a high priority tag. After reading the book and testing some of the hacks I've learned from it, I'll try to tell you what is so good about this publication. By browsing the first chapter of the book, I was unpleasantly surprised - the first two dozens of hacks, weren't the usual hacks I expected. If you are not introduced to what O'Reilly hacks are, here is a suitable sentence from the book's covers: "O'Reilly's Hacks Series reclaims the term hacking for the good guys - innovators who explore and experiment, unearth shortcuts, create useful tools and come up with fun things to try on your own". What troubled me about the mentioned early hacks of this book was, that each hack didn't talk about some geeky tool or a way to do something, but rather focused on one of the Wireless related protocols or services. So here the readers can learn about 802.11 (a, b and g), 802.1X, cellular data networks, Bluetooth etc. I'm not saying at all that these topics shouldn't be included, but maybe they could be placed in some kind of introduction, rather than in actual hacks space. Nevertheless, the author shares his experience on the these topics, in the way of noting the pros, cons and recommendations for each issue.

Bruce Schneier, master cryptographer and idol of the computer underground, targets those short-attention-spanners in his latest book, "Secrets and Lies: Digital Security in a Networked World." Aiming straight for the vaunted "general audience," he peppers the 400-plus pages with Yogi Berra quotes, analogies drawn from "Star Wars" and trivia tidbits from Greek mythology. But the folksy wit doesn't obscure a core message as frighteningly entertaining as Dr. Lecter's flesh-eating antics: In cyberspace, you're dead meat on a stick.

In 'Secrets and Lies', renowned security expert Bruce Schneier explores the paradoxes of digital security, revealing how cybersecurity often fails to provide real protection.
