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.

cyber attacknational securitycyberwarfareExamining U.S. Cybersecurity Shortcomings Amid Strong Offensive Potential
Although the United States likely has the best cyberwar capabilities in the world, "that offensive prowess cannot make up for the weaknesses in our defensive position," one-time presidential advisor Richard Clarke argues in his forthcoming book Cyber War.. Clarke -- who served as special advisor to the president for cybersecurity in 2001 and now teaches at Harvard's Kennedy School for Government and works at Good Harbor Consulting -- fears that any outbreak of cyber warfare would spill over into more violent conflict. "Far from being an alternative to conventional war, cyber war may actually increase the likelihood of the more traditional combat with explosives, bullets and missiles," Clarke writes in his book, which is due out April 20.

Dependence on the Internet for voice communications and data distribution will increase the likelihood of cyberwarfare, a high-tech research firm said Thursday. Much like the nuclear threat during the Cold War in the last century, cyberwarfare is a potential catastrophe that the U.S. and other nations must be prepared to combat, Gartner Inc. said.

Dependence on the Internet for voice communications and data distribution will increase the likelihood of cyberwarfare, a high-tech research firm said Thursday. Much like the nuclear threat during the Cold War in the last century, cyberwarfare is a potential catastrophe that the U.S. and other nations must be prepared to combat, Gartner Inc. said. Given the rate of adoption of Internet-based technology, nations will have the ability to conduct cyberwarfare by 2005. "The world's not going to hell in a hand basket, so we can get that off the table," David Fraley, author of the recent Gartner report, said. "What's important for people to do is continuity planning--be aware of the different threats and vulnerabilities that could hit their organizations." Organizations could suffer irreparable harm if they don't have a strategy for keeping their businesses running, if facilities are unable to operate. "The difference between cyberwarfare and hacking is the magnitude," Fraley said. "Cyberwarfare is on a much grander scale." Increasing the possibility of cyberattacks is the ever-increasing use of Internet-protocol networking technology to connect critical infrastructure, as well as the movement in voice communications from a circuit- to packet-switched architecture, the research firm said. IP networks carrying voice traffic use voice over IP (VoIP) equipment that is susceptible to traditional Internet threats like worms, viruses and break-ins from hackers. Denial-of-service attacks, for example, that often take down web sites, could be used todisrupt the flow of voice-carrying packets on an IP network, causing a major breakdown in communications.

In a recent report on terrorism, the CIA stated, "Cyberwarfare attacks against our critical infrastructure systems will become an increasingly viable option for terrorists." According to the report, various terrorist groups, including al-Qaeda and Hizballah, are becoming more adept at using the Internet and computer technologies, and the FBI is monitoring an increasing number of cyber threats. The report singled out a group called Aleph as the terrorist entity that places the highest level of importance on developing cyber skills. "This group identifies itself as a cyber cult and derives millions of dollars a year from computer retailing," it stated. .

Cybersecurity is slipping, a panel of experts last month told lawmakers at a hearing of the Joint Economic Committee. The biggest threat is cyberwarfare sponsored by foreign governments, said Lawrence K. Gershwin, the national intelligence officer for science and technology for the CIA's National Intelligence Council. Only nations have enough backing for "the future prospect of causing widespread, long-duration damage to critical U.S. infrastructures," he said. The joint committee's ranking Senate Republican, Sen. Robert F. Bennett of Utah, said observers have missed the forest for the trees. "The complex issues of cybersecurity and infrastructure protection are overshadowed by the attention paid to hacking exploits and Web site defacements," he said.

The Army will allow an opposing force to conduct cyberwarfare against the first digitized division when it demonstrates the combat capabilities of the information technology-dependent force in April. The Army came under fire from critics within its own ranks, in Congress and elsewhere when it started experimenting with digitized armored forces from the 4th Infantry Division during an Advanced Warfighting Experiment at Fort Irwin, Calif., in 1997. Service leaders said at the time that much of the equipment was prototypical, and the field exercise was an experiment that already had too many variables. Allowing the opposing force to use network attack tools likely would have been too much for the digitized corps? fledgling network. The message at the time was that the service would put the digitized division's network security to the test at a later date. The link for this article located at FCW is no longer available. .
