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...

information securitycyberwarfaredigital warfareUnderstanding Cyberwarfare: Current Challenges from States and Hackers
The cyberwar discussion is mired in confusion. What defines an act of cyberwar? Is it a sophisticated hack from China or Russia that shuts down the U.S. power grid? Is it a rogue group like Anonymous breaking into government sites? Is it all the spying China has been doing for several years now? . And what about Stuxnet and Duqu? Were those creations an act of war by the U.S. and Israel against Iran? Does a cyberwar involve government and military sites only or does it include the networks of private enterprise as well? The link for this article located at CSO Online is no longer available. . In today’s cyberwarfare landscape, the mix of state and rogue cyber actions creates major global security challenges, increasing risks of collateral damage and uncertainty.

open sourcesecurity lessonsexport controlsExploring Cold War Software Sabotage Insights for Exporters
A reminder of how important these are came last week with a revelation from the Cold War era, contained in a new book by a senior US national security official. Thomas Reed's At The Abyss recounts how the United States exported control software that included a Trojan Horse, and used the software to detonate the Trans-Siberian gas pipeline in 1982. The Trojan ran a test on the pipeline that doubled the usual pressure, causing the explosion. Reed was Reagan's special assistant for National Security Policy at the time; he had also served as Secretary of the Air Force from 1966 to 1977 and was a former nuclear physicist at the Lawrence Livermore laboratory in California. The software subterfuge was so secret that Reed didn't know about it until he began researching the book, 20 years later. . . .. China has irked US wireless manufacturers by insisting that they conform to the PRC's encryption technology, we reported last week. Some commentators have castigated China for protecting its own fledgling tech industry. But that excludes the country's very understandable security concerns.

The software subterfuge was so secret that Reed didn't know about it until he began researching the book, 20 years later. The scheme to plant bugs in Soviet software was masterminded by Gus Weiss, who at the time was on the National Security Council and who died last year.Soviet agents had been so keen to acquire US technology, they didn't question its provenance. "[CIA Director] Bill Casey at Weiss at the NSC decided to help the Russians with their shopping. Every piece of sw would have an added ingredient," said Reed to NPR's Terry Gross last week. The software sabotage had two effects, explains Reed. The first was economic. By creating an explosion with the power of a three kiloton nuclear weapon, the US disrupted supplies of gas and consequential foreign currency earnings. But the project also had important psychological advantages in the battle between the two superpowers. "By implication, every cell of the Soviet leviathan might be infected," he writes. "They had no way of knowing which equipment was sound, which was bogus. All was suspect, which was the intended endgame for the entire operation." Tools you can trust The two great trading powers, China and the USA, are not currently engaged in a Cold War. But does that mean that the Cold War lessons are invalid? .

At first it was a combination playground, library and meeting house for scientists and soldiers, an inviolate virtual world. Companies later tried to turn it into a mall. Now, it's becoming a borderless battlefield. In recent weeks, the Middle East conflict spilled over into the Internet as Web sites throughout the region have been altered with messages advocating online attacks against other sites, both Israeli and pro-Palestinian -- in some cases providing the software that make such attacks possible. This isn't the first conflict to see hacker activity; similar incidents have occurred in the Balkans, Russia, Mexico and China. ``It's become almost standard practice in any political conflict to see that occur,' said Eugene Spafford, a computer security expert who runs the Center for Education and Research in Information Assurance and Security at Purdue University And like the Internet itself, this cyberwarfare simply ignores national boundaries. Many attacks on Israeli sites have originated in Pakistan, as did an attack earlier this month against the Web site for the American Israel Public Affairs Committee, a lobbying group. The site was defaced with anti-Israeli commentary. But this exploit took cyberwar a step further: The attacker stole some 3,500 e-mail addresses and 700 credit card numbers, sent anti-Israeli diatribes to the addresses and published the credit card data on the Internet.
