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...

security advisorynetwork securityIPv6SANS Security Warning on IPv6 Migration Risks and Challenges
IT security teams must start preparing now for the increased security risks that may arise from implementation of the forthcoming IPv6 protocol, warned security training and research organisation the SANS Institute.. SANS chief research officer Johannes Ullrich argued that many organisations have failed to grasp the full impact of a move to IPv6, or the amount of time needed to plan, test and secure a migration strategy. "One of the problems is the accidental implementation of IPv6. You may already have IPv6 on your network without knowing about or configuring it," he said. . SANS emphasizes the challenges faced by businesses transitioning to IPv6, underscoring the importance of robust planning and thorough testing methodologies..

Security has been one of the selling points for the new Internet protocol, but IPv6 is not inherently secure, say those planning its implementation. "The biggest challenge we have of the next decade or so is security," Latief Ladid, president of the IPv6 Forum, said today at the U.S. IPv6 Summit in Arlington, Va. The Internet Engineering Task Force is still working on IPv6 security elements and "many of them need to be tested in the real world," said security consultant Richard Graveman.

There has been a great deal of difficulty experienced in getting research performed by cryptographers in the last decade or so (beyond basic algorithms such as SHA and AES) applied in practice. The reason for this is that cryptographers don't work on things that implementors need because it's not cool, and implementors don't use what cryptographers design because it's not useful or sufficiently aligned with real-world considerations to be practical. As a result, security standards are being created with mechanisms that have had little or no security analysis, often homebrew mechanisms or the standards editor's pet scheme. The problem is a lack of communication: Cryptographers often don't seem aware of the real-world constraints that their design will need to work within in order to be successfully deployed. The intent of this document is to cover some of those real-world constraints for cryptographers, to point out problems that their designs will run into when attempts are made to deploy them. Also included is a motivational list of extremely uncool problems that implementors have been building ad-hoc solutions for since no formal ones exist. "Looking at all of the security protocols deployed in the last 10 years, you'd be forgiven for thinking that the only developments in crypto during that time (beyond basic algorithms) were HMAC and SPEKE" The link for this article located at Peter Gutmann is no longer available. .

"There is some outstanding technology available, and in publicly available algorithms," Bauer told Newsbytes after his speech. "The problem isn't that there's no good cryptographic technology available. The problem is that it's fiendishly difficult to implement the technology in a secure fashion." Public key infrastructure (PKI) has promise as a secure technology too, he says. It involves the use of a coded key that an end user can hand out to the public, much as a phone number is given out. Others can use that key to encrypt secure documents and send them back to be opened by the end user. But they cannot be used without PKI's second component, a private key that only they can know or access.." The link for this article located at Computer User is no longer available. .
