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...

cybersecurityhackingidentity theftKevin Mitnick: The Art Of Hacking And Cat-And-Mouse Games With Agents
By 1992, federal agents were closing in on Kevin Mitnick, the FBI's most-wanted hacker. But he already knew this; he was watching them.. Mitnick broke into the local cell phone network, allowing him to detect when agents were near his apartment. When they were close, he removed evidence but left behind a box of donuts in the refrigerator, labeling them "FBI donuts" to annoy his pursuers. Such games of cat and mouse are recounted in Mitnick's new book, "Ghost in the Wires," which details his life as a hacker and fugitive, breaking into computer networks, creating false identities and running from authorities.. Morris recounts his escapades of rebellion against government officials and the craft of cyber infiltration in his memoir, "Chasing Shadows.".

cyber attackcomputer networksdefense technologyISEAGE Lab at Iowa State University: Cyber Attack Research Facility
A new test laboratory at Iowa State University will allow researchers to study how computer networks respond to massive Internet attacks and could lead to breakthroughs in computer defenses and forensics, said a researcher behind the project. . The new test network, ISEAGE (Internet Simulation Event and Attack Generation Environment), was funded by a $500,000 grant from the Department of Justice. ISEAGE is the first research lab to be able to re-create any cyber-attack on any part of the Internet infrastructure, said Doug Jacobson, director of information assurance at ISU, in Ames. Jacobson is also the chief technology officer of Palisade Systems Inc., a security technology vendor, also in Ames. ISEAGE uses a 64-processor cluster connected via high-speed switching gear at ISU's Research Park. The cluster is linked to a central disk storage system running Free BSD Unix. Each processor can re-create 50 routing points, giving researchers tremendous flexibility to reproduce network attacks. The guts of the new test lab are software tools, developed by Jacobson, that let researchers change traffic patterns, replay attacks in endless configurations and collect attack data, Jacobson said. "We can make an attack that looks like it came from 1,000 computers, but we don't need 1,000 computers to do it," he said. The testbed can just as easily simulate attacks from 100,000 Internet-connected machines—or from every Internet address in existence, Jacobson said.

University campuses and corporate boardrooms aren't the only places that benefit from diversity -- computer networks and the Internet could stand up better to viruses and worms if they relied on more diverse software, according to computer scientists at Carnegie Mellon University and the University of New Mexico. The scientists are using a US$750,000 grant from the U.S. National Science Foundation (NSF) to study how cyber diversity can help defend against the scourge of computer viruses and worms, according to the NSF. The NSF is an independent US government agency that funds scientific research. Researchers at the two universities will look at ways to change different components of a computer's software code that are transparent to users, but that introduce a kind of "genetic diversity," according to a statement from Dawn Song, an assistant professor of computer science at Carnegie Mellon in Pittsburgh. Such changes might not protect any single machine, but could make computer networks and the Internet less prone to outbreaks of computer viruses like Code Red, Slammer and the recent Blaster worms, which spread by exploiting known vulnerabilities in operating systems and software applications, according to Carl Landwehr, program director for the Cyber Trust program at NSF.

By the age of 20, Benjamin Breuninger's life was a mess. Estranged from his mother and stepfather, a dropout with no job and months behind on his rent, he often went a day or more without eating. Online, he had a different life. There, he was Konceptor, a skilled hacker who broke into computer networks, defaced Web sites and strutted in online newsgroups such as alt.2600, where he closed his frequent postings with this warning: "The Keystroke is mightier than the Pen. And this is My GAME." In 2 1/2 years in the late 1990s, Breuninger hacked into dozens of computer systems. He peeked at the payroll of a nearby Taco Bell, left messages supporting Jesse Ventura on the St. Paul Public Library and KSTP radio Web sites and stole thousands of Internet e-mail accounts and passwords. Breuninger's online exploits ended when the FBI arrested him at his Bloomington apartment Sept. 11, 2000, for hacking into and downloading files from the Lawrence Livermore National Laboratory in California. . Benjamin Breuninger, a coding prodigy, led a double life of youthful aspirations and hacking thrills that ultimately caught the attention of authorities. hacker biography, cybersecurity story, ethical hacking, computer networks, online identity. .

The FBI is considering important changes to its premier cybersecurity unit, responsible for protecting the nation's most important computer networks, but indicated Wednesday it won't dismantle the unit as some in Congress and the Bush administration have feared. FBI Director Robert Mueller has outlined a plan on Capitol Hill in recent weeks to break up the $27 million-a-year National Infrastructure Protection Center (NIPC), formed in February 1998 to watch over the nation's systems controlling banking, water, power, telecommunications and government, congressional and administration sources said Wednesday. They added that they expected Mueller to make a formal decision as early as next week. The proposal affecting the unit, whose reputation has improved markedly in the past year after a string of early embarrassments, quickly raised concerns among some lawmakers, Bush administration officials and industry experts. They worried that a narrow focus by the FBI on criminal investigations into computer attacks might discourage corporations from disclosing details of threats and attacks on their private networks.

The Defense Department is taking additional steps to shield its computer networks against hackers and terrorists but it also must defend itself from insiders, lawmakers were told Thursday. The Department is increasingly dependent on a "global information environment" over which it has little control, said Linton Wells, an acting assistant defense secretary. That dependence increases U.S. vulnerability to threats externally - and internally. "Increasingly, we see that we have to be able to guard against the inside - the Ameses and the Hanssens," he said, referring to veteran intelligence agents accused of espionage.
