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...

Put simply, a security operations guide is a document that clearly defines your network's security-related policies and procedures. Over the years, I've done security-related consulting for a number of organizations. In these real-world environments, I've always found that the organizations that seem to have the best security actually have two security operations guides. One of these guides is intended for the people who are actually in charge of security management. The other is intended for the end users. The end user security guide is by far the simpler of the two documents. The first company that I saw publish an end user security guide was a large insurance company. It compiled guides that were 10 to 15 pages long. Each of these guides explained exactly what was expected of employees when it came to security. The employees were then required to sign a form saying that they had received a copy of this guide before they were given a user name and password. Although I think this company had the right idea, the guides had small print and a lot of legal mumbo jumbo, and were very hard to read. The company may have kept the lawyers happy, but I doubt many employees actually took the time to read and try to understand the guide.

That was the message from experts who participated in working groups under federal cybersecurity czar Richard Clarke and shared what they learned. . .. Attention, Wi-Fi users: The Department of Homeland Security sees wireless networking technology as a terrorist threat. That was the message from experts who participated in working groups under federal cybersecurity czar Richard Clarke and shared what they learned at this week's 802.11 Planet conference. Wi-Fi manufacturers, as well as home and office users, face a clear choice, they said: Secure yourselves or be regulated. "Homeland Security is putting people in place who will be in a position to say, 'If you're going to get broken into ... we're going to start regulating,'" said Cable and Wireless security architect Shannon Myers in a panel dubbed "Homeland Security vs. Wi-Fi." Myers was one of several consultants for President Bush's Critical Infrastructure Protection Board, which is finalizing its National Strategy to Secure Cyberspace. Since being named special advisor to the president for cyberspace security last year, Clarke has stressed wireless access points as a national security threat. "Companies throughout the country have networks that are wide open because of wireless LANs.... Millions of houses are getting connected, which means that more and more are getting vulnerable," Clarke told attendees at the Black Hat Security Briefings in Las Vegas earlier this year. "We know that (an attack) could bring down the network of this country very quickly. Once you're on the network, it doesn't matter where you got in," said Daniel Devasirvatham, who headed the Homeland Security task force for the Wireless Communications Association International trade association. Devasirvatham said the telecom industry was represented at security planning talks with federal agencies, but the wireless sector itself was not. "Do youconsider yourself part of the telecom industry?" he asked the 802.11 Planet audience. "If you're a nethead instead of a Bellhead, you probably don't. I think there's a major disconnect here." But Myers acknowledged that regulators were frustrated in their search for a quick fix to plug Wi-Fi holes. "There's just not a lot of technology out there right now that can be used to secure the technology in place," she said. "They're not at a point where they can say, 'This will solve the problem,' and mandate it." Rather, the most recent draft of the National Strategy document lists stopgap steps that home and office Wi-Fi users should take to make their networks harder to crack. The National Institute of Standards and Technology's Wireless Network Security document contains more detailed guidelines. Speakers called on corporate Wi-Fi customers to participate in creating security enhancements and best practices, lest regulators do it for them. "Expert advice needs to be obtained from more than just the industry that makes the equipment," Devasirvatham said. Conference attendees were split on the potential of wireless nodes as terrorist access points. Boingo CEO Sky Dayton suggested turnkey security standards under development would improve the technology's reputation. "It's possible to secure a wireless network today," he said. "But it needs to get easier." The link for this article located at Wired News is no longer available. .
