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...

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...

web securitysecure networkinganonymityVeiled: New Browser-Based Darknet for Secure Communication
A pair of researchers has discovered a way to use modern browsers to more easily build darknets -- those underground, private Internet communities where users can share content and ideas securely and anonymously. Billy Hoffman, manager for HP Security Labs at HP Software, and Matt Wood, senior security researcher in HP's Web Security Research Group, will demonstrate a proof-of-concept for Veiled, a new type of darknet, at the Black Hat USA conference in Las Vegas next month. . Darknets, themselves, are nothing new; networks like Tor, FreeNet, and Gnutella are well-established. The HP researchers say Veiled is the same idea, only much simpler: It doesn't require any software to participate, just an HTML 5-based browser. "We've implemented a simple, new darknet in the browser," Wood says. "There are no supporting [software] programs." Unlike its predecessors, Veiled doesn't require much technical know-how to join, either. "The coolest thing about this is it lowers the barrier to entry to a darknet," Hoffman says. "You could put some very interesting applications on top of it. It could be a way to do secure whistle-blowing, [for example]. When you have something decentralized like this, no one can control or stop it." No one can take it down, either, he adds, all of which makes it more approachable for a wider community of legitimate users.

Adoption of virtual private networks (VPNs) based on the browser-based SSL technology is shaping up to be one of the key trends of 2004, especially as enterprises mobilize their workforces.

Adoption of virtual private networks (VPNs) based on the browser-based SSL technology is shaping up to be one of the key trends of 2004, especially as enterprises mobilize their workforces. SSL allows for secure access to corporate networks from virtually any browser and so provides flexibility for roaming workers with laptops or smartphones, as well as simple mechanisms that reduce support costs. This week, two security companies, NetScreen and F5, said that their first quarter revenues had been boosted by their acquisitions last year of SSL specialists, whose products have been added to their more traditional IPsec VPNs and firewalls. The main demand is coming from companies with large mobile workforces, said F5. . In 2004, SSL-based VPNs revolutionized secure remote access for mobile workers, enhancing user experience and compatibility with corporate networks.

The drastic drop in the cost of WLAN (wireless LAN) gear, along with the great extent to which 802.11b networking is now being built into notebook and handheld computers, virtually guarantees that wireless networking will secure a spot on your agenda whether you've placed it there or not. IT administrators would do well, then, to head off a wireless groundswell by taking the lead in deploying these networks and doing so with the sort of attention to security that end users often can't afford to pay. In the past year, there's been some encouraging movement toward more secure wireless networking standards. However, as security standards for these networks mature, so, too, will the tactics of those who would crack them. Wireless networks are fundamentally less secure than wired ones. Nearly every business, however, is already plugged in to perhaps the least secure network of all the Internet. By regarding WLANs with the same suspicion they do the Internet, companies can unwire themselves with relatively high confidence. The link for this article located at eWeek is no longer available. . As wireless LANs expand and standards advance, robust security is vital. Here are effective strategies to strengthen your wireless network security..

Because the tunnel appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This tunneling allows VPN sites to share information with eachother over the Internet without exposing any information to others. A single tinc daemon can accept more than one connection at a time, thus making it possible to create larger virtual networks, because some limitations are circumvented.
