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...

cybersecurity riskdefense departmentGAO reportUS Department Of Defense Cybersecurity Risks In Weapons Systems
The Department of Defense will have to ramp up its cybersecurity efforts now that it's planning to spend $1.66 trillion to develop major weapons systems. According to a new report (PDF) by the Government Accountability Office, nearly all of Pentagon's weapons systems are vulnerable to cyberattacks.. The DoD, the report reads, didn't make cybersecurity a priority, even though GAO has been warning it for decades about the risks it's taking by not making sure its systems are properly protected. That leaves the nation's weapons, such missiles and drones, susceptible to attacks meant to take over their controls. The link for this article located at Engadget is no longer available. .

The Pentagon said today that an attempt to send a virus through its systems last week was thwarted before damage could be caused. On the morning of Feb. 14, someone "spoofed" the Defense Technology Information Center (DTIC) header, camouflaging the sender's real address to make recipients think the message had come from the Defense Department. The message had a virus attached and was sent through Pentagon computers to two mailing lists. "Our computers caught the virus and stripped it out," said Terry Davis, manager of the Public Web Program in the Office of the Secretary of Defense. "So what went out was the original text message that was sent in the e-mail, but the virus and the attachment were both stripped." The link for this article located at FCW is no longer available. .

What would happen if open source software were banned in the Defense Department? A recent study conducted by Mitre Corp. for DOD posed that hypothetical question and found this answer: The department's cybersecurity capabilities would be crippled and other areas would be severely impacted. Mitre Corp. was asked to develop a listing of open-source software applications at DOD and to collect representative examples of how those applications are being used. Over a two-week period, an e-mailed survey identified 115 applications and 251 examples of use, and Mitre's report acknowledged that actual use could be "tens of thousands of times larger than the number of examples identified." To help analyze the data, the hypothetical question was posed: What would happen if open-source software were banned at DOD? Version 1.2 of the report, "Use of Free and Open Source Software (FOSS) in the U.S. Department of Defense," was released Sept. 20 to the Defense Information Systems Agency (DISA), and found that open-source software applications are most important in infrastructure support, software development, security and research.

Should the Defense Department assume responsibility for safeguarding the countrys communications infrastructure? A retired Navy vice admiral now working in the private sector said the time has come for public debate on the question. "Were going to have to make a decision of that magnitude," said Michael McConnell, a retired intelligence officer and former director of the National Security Agency. "What would the FBI say? Or the Judiciary Committee?" he asked. Civilian law enforcement is responsible for investigating cybercrime and network attacks, but McConnell suggested that those agencies do not have the staffing necessary to defend against the terrorist-backed and state-sponsored cyberattacks that are now possible.

The Defense Department has made little progress during the past two years in implementing electronic commerce efforts, according to a new General Accounting Office report. Unless steps are taken to fix the shortcomings, the department's efforts to fully integrate an e-commerce program could fall far short of expectations. Under the Defense Reform Initiative, launched in May 1998, DoD aimed to make much greater use of such e-commerce tools as expanding the use of purchase cards, establishing an electronic mall for customers and moving towards a paperless contracting environment. While the department has taken steps to implement some of these programs, it's lacking an overall vision for how it intends to move into the e-commerce world, according to the report, "Defense Management: Electronic Commerce Implementation Strategy Can Be Improved" (NSIAD-00-108).
