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...

open sourceopen source communitycommunity trustUniversity of Minnesota Faces Scrutiny Over Research Ethics Issues
University of Minnesota researchers' recent "experiment" - which involved sneaking vulnerabilities into the Linux kernel code base and then effectively bragging about it in the name of research - highlights the role of ethics in cybersecurity. . Nobody wants to be a proverbial guinea pig; least of all, developers donating their time and energy to making the world a better place. You’d think with all the recent discussion about consent, researchers would more carefully observe ethical boundaries. Yet, a group of researchers from the University of Minnesota not only crossed the line but ran across it, screaming defiantly the whole way. In response, the Linux Foundation, which is the core of the open source community, took the unprecedented step of banning the entire University of Minnesota from contributing to the Linux kernel. The open source community is built upon the principles of trust, cooperation and transparency. This group donates time and high-value industry skills to create, maintain and improve free and widely adopted software in the interest of making technology more accessible.

DDoS attackmotivationhacker journeyMitchell Frost's Path: Insights into DDoS Attacks and Hacker Motivations
In 2006, Mitchell Frost, then a 19-year-old college student at the University of Akron, used the school's computer network to control the botnets he had created. Authorities say between August 2006 and March 2007, Frost launched a series of denial of service (DDOS) attacks against several conservative web sites, including Billoreilly.com, Anncoulter.com and Rudy Giuliani's campaign site, Joinrudy2008.com. . He is accused of taking down the O'Reilly site five times, as well as disrupting the University of Akron's network during a DDOS attack Frost allegedly launched on a gaming server hosted by the university.

corporate securityinformation warfareDDoS defenseSymbiot DDoS Tool Launch Raises Ethical and Legal Issues
Security company Symbiot is about to launch a product that can hit back at hackers and DDoS attacks by lashing out with its own arsenal of tricks, but experts say it may just be a bit too trigger-happy. Symbiot, a Texas-based security firm, is preparing to launch a corporate defence system at the end of March that can fight back against distributed denial-of-service (DDoS) and hacker attacks by launching a counter-strike. . . .. Security company Symbiot is about to launch a product that can hit back at hackers and DDoS attacks by lashing out with its own arsenal of tricks, but experts say it may just be a bit too trigger-happy Symbiot, a Texas-based security firm, is preparing to launch a corporate defence system at the end of March that can fight back against distributed denial-of-service (DDoS) and hacker attacks by launching a counter-strike. In advance of the product launch, Symbiot's president, Mike Erwin, and its chief scientist, Paco Nathan, have outlined a set of "rules of engagement for information warfare", which they say should be part of corporate security policy to help companies determine their exact response to an incoming attack. "Until today, security solutions have been totally passive in nature. Merely erecting defensive walls around the perimeter of an enterprise network is not an adequate deterrent," said Erwin, who argues that to have a complete defence in place, offensive tactics must be employed. The company said it bases its theory on the military doctrine of "necessity and proportionality", which means the response to an attack is proportionate to the attack's ferocity. According to the company, a response could range from "profiling and blacklisting upstream providers" or it could be escalated to launch a "distributed denial of service counter-strike". Security experts expressed alarm at the company's plans. Graham Titterington, principal analyst at Ovum, said "such a counterattack would not be regarded as self-defence and would therefore be an attack. It would be illegal in thosejurisdictions where an anti-hacking law is in place." He added that because many hacking and DDoS attacks are launched from hijacked computers, the system would be unlikely to find its real target: "Attacks are often launched from a site that has been hijacked, making it an unwitting and innocent -- although possibly slightly negligent -- party." Richard Starnes, director of incident response at Cable and Wireless Managed Security Services, said he would not employ an "active defence technique" because there are legal and ethical issues involved. Also, he would not be happy about any product "specifically designed to launch attacks" being put into commercial production. Starnes said it would be easy to hit the wrong target and even if it was the right target, there could be collateral damage: "You may be taking out grandma's computer in Birmingham that has got a 100-year-old cookie recipe that has not been backed up. The attack could also knock over a Point of Presence (PoP), so you are not only attacking the target, but also the feeds before them -- this means taking out ISPs, businesses and home users." Jay Heiser, chief analyst at IT risk management company TruSecure, said that he expects the product to have "emotional appeal" to companies that have been targets, but "that is a very bad criterion for choosing risk-reduction measures."
