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...

They have their networks locked tight, their data hidden behind firewalls and their e-mail scanned by virus protection software. But too many IT managers and security officers overlook a crucial security risk: the telephone system. As voice over IP (VoIP) setups become more common within enterprises, the risk of compromise of phone services is on the rise. "When it comes to telephone systems, we're so comfortable that when a security breach occurs, it's like being punched by someone you love -- you're just not expecting it," Jim Puchbauer, director of marketing at AltiGen Communications, told the E-Commerce Times.

A vulnerability in the most widely used FTP server program for Linux has left numerous sites open to online attackers, a situation worsened when Red Hat mistakenly released information on the flaw early, leaving other Linux companies scrambling to get a fix out. "Other vendors didn't have a patch," said Alfred Huger, vice president of engineering for network security information provider SecurityFocus. The company has been working with vendors to fix the vulnerability after computer security company Core Security Technologies alerted them to the problem Nov. 14. "The fix is not rocket science," Huger said. "But we weren't working at a breakneck pace to get a patch out, because everyone was working together."

Employees are the biggest threat to network security - and they don't even know it. Unauthorised equipment attached to a company network can, according to Robin Dahlberg, UK MD of Internet Security Systems, compromise the best efforts of a network manager to secure the system by creating a "backdoor" into the network. Protecting a company from external attacks from "recreational hackers" was almost irrelevant if a system was not properly secured internally, he says.

James Woolsey, speaking on a panel here Wednesday, warned that international spies and terrorists would soon wield a more purposeful and dangerous breed of computer virus than ever seen before. Unlike Melissa, CIH or the recent ILOVEYOU virus, these viruses would not be destructive, but "instructive," Woolsey said. As described by Woolsey, an "instructive" virus would spread covertly and use minimal system and network resources as it instructs computers to perform certain functions undetected, like stealing particular secrets from specific targets. Woolsey gave a law firm with a sensitive case as an example victim. "They get a virus into the local area network that says, 'transfer at midnight, Sunday night, all files on such-and-such a case to this particular outside computer,'" Woolsey explained. "If you've got an instructive virus in your system that is reading out your files to one of your competitors, that may have been going on for some time."
