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...

Damn Vulnerable Linux (DVL) is everything a good Linux distribution isn't. Its developers have spent hours stuffing it with broken, ill-configured, outdated, and exploitable software that makes it vulnerable to attacks. DVL isn't built to run on your desktop -- it's a learning tool for security students. . DVL is a live CD available as a 150MB ISO. It's based on the popular mini-Linux distribution Damn Small Linux (DSL), not only for its minimal size, but also for the fact that DSL uses a 2.4 kernel, which makes it easier to offer vulnerable elements that might not work under the 2.6 kernel. It contains older, easily breakable versions of Apache, MySQL, PHP, and FTP and SSH daemons, as well as several tools available to help you compile, debug, and break applications running on these services, including GCC, GDB, NASM, strace, ELF Shell, DDD, LDasm, LIDa, and more. DVL was initiated by Thorsten Schneider of the International Institute for Training, Assessment, and Certification (IITAC) and Secure Software Engineering (S The link for this article located at Linux.com is no longer available. .

software issuesecurity reportweb flaw2006 Web Security Report: Overview of Increasing Vulnerabilities and Flaws
Less rigor in Web programming, an increasing variety of software, and restrictions on Web security testing have combined to make flaws in Web software the most reported security issues this year to date, according to the latest data from the Common Vulnerabilities and Exposures (CVE) project. A draft report on the latest numbers from the vulnerability database found that 4,375 security issues had so far been cataloged in the first nine months of 2006, just shy of the 4,538 issues documented last year. . The data shows that Web flaws have continued their meteoric rise since 2005, capturing the top-three spots on the list of most common vulnerabilities. Buffer overflows, a perennial favorite, fell to the No. 4 slot. "The takeaway is that researchers are paying a lot more attention to Web vulnerabilities, and if companies don't want to get caught up in that, then they need to pay attention to those flaws," said Steven Christey, the security researcher that authored the draft report and the CVE Editor for The MITRE Corp., a nonprofit government contractor. The jump in Web-based vulnerabilities is fueled by the simplicity of exploiting many of the most common Web vulnerabilities, the enormous number of Web applications freely available, and the difficulty in eradicating cross-site scripting flaws.

In 2006, vulnerabilities in web applications escalated significantly due to more accessible exploits and an increase in software diversity, raising substantial security alarms..

Knowledge of C or any other high level language is essential to this discussion. Basic knowledge of process memory layout is useful, but not necessary. Also, all the discussions are based on Linux running on x86 platform. The basic concepts of buffer overflow, however, are the same no matter what platform and operating system is used.

There are over 30,000 hacking-oriented sites on the Internet, offering easy to use click-and-hack programs and scripts for anyone to download. These easily accessible hacking tools have opened the door for a multitude of new exploits. The first big-name hackers include Steve Wozniak, Bill Gates and Linus Torvalds, all now highly recognizable names behind many of the computer technologies used today. These early hackers had a love of technology and a compelling need to know how it all worked, and their goal was to push programs beyond what they were designed to do. Back then, the word "hacker" didn't have the negative connotation it has today. The original hacker ethic, rooted out of simple curiosity and a need to be challenged, appears to be dead.
