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...

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...

securitykernel upgradelinux kernelWireGuard In Linux 5.6 Improves Performance And Simplifies Upgrades
WireGuard has finally made it into the mainline Linux kernel - meaning Dynamic Kernel Module Support (DKMS) builds will no longer be necessary, making routine kernel upgrades significantly faster! . We've been anticipating WireGuard's inclusion into the mainline Linux kernel for quite some time—but as of Sunday afternoon, it's official. Linus Torvalds released the Linux 5.6 kernel, which includes (among other things) an in-tree WireGuard. Phoronix has a great short list of the most interesting new features in the 5.6 kernel, as well as a longer "everything list" for those who want to make sure they don't miss anything. If this is the first time you're hearing about WireGuard, the TL;DR is that it's a relatively new VPN (Virtual Private Network) application that offers a leaner codebase, easier configuration, faster connect times, and the latest and most thoroughly peer-reviewed and approved encryption algorithms. You can find a more detailed introduction in our initial August 2018 coverage. . The highly anticipated integration of WireGuard into the core Linux kernel boosts efficiency and streamlines updates for those utilizing VPN services..

access controlfirewallnetwork performanceUnderstanding Firewall Audit Tools for Better Security and Compliance
Firewall audit tools automate the otherwise all-but-impossible task of analyzing complex and bloated rule sets to verify and demonstrate enterprise access controls and configuration change-management processes.. Although the market has been driven by compliance--it was essentially created by PCI DSS--these tools can also allow organizations to improve network performance, reduce downtime, improve security and reassign staff from shooting down firewall issues and analyzing configurations to taking on tasks that help grow the business. The problems are familiar to organizations of all sizes--from those with just one or two overtaxed and inefficient firewalls, to large, distributed enterprises with scores or hundreds of firewalls administered by many business units, often all following different policies that may have been written before the units' acquisitions.

dns securitykey managementdigital signaturesF5 Networks And Infoblox Integrated DNS Security Announcement
F5 Networks and Infoblox announced on Monday what they claim is the first integrated solution that combines DNS Security Extensions key management and signing capabilities with global server load balancing to boost performance.. DNSSEC is an Internet standard that prevents spoofing attacks by allowing Web sites to verify their domain names and corresponding IP addresses using digital signatures and public-key encryption. DNSSEC is being deployed across the Internet infrastructure, from the root servers at the top of the DNS heirarchy to the servers that run .com and .net and other top-level domains, and then down to the servers that cache content for individual Web sites. DNSSEC has been in the news in recent weeks, with Comcast being the first U.S. carrier to announce a public trial of its DNSSEC signing and resolution services.

user experiencenetwork performanceinternet infrastructureGoogle DNS Service: Enhancements for Fast and Reliable Browsing
Google wants to speed up a key part of the Internet's inner workings called the Domain Name System and is inviting technically savvy folks to try their ideas out. The DNS is a crucial part of the Internet. It converts the text addresses people can remember into the numeric Internet Protocol addresses actually used to locate information on the Internet. For example, CNET.com's IP address is 216.239.122.102.. When you visit a Web page, a DNS server that's part of a vast distributed network often must perform that conversion--called resolving a host--many times. With the Google Public DNS service, Google wants to be that server. "Our research has shown that speed matters to Internet users, so over the past several months our engineers have been working to make improvements to our public DNS resolver to make users' Web-surfing experiences faster, safer, and more reliable," said product manager Prem Ramaswami in a blog post introducing the Google Public DNS service.

Security experts finally have a handle on mystery malware that was generating loads of suspicious IP traffic over the last few weeks. Researchers at Internet Security Systems Inc. say the culprit, which was first thought to be a new breed of Trojan, is actually a distributed network mapping tool that also acts as a listening agent. Dubbed Stumbler, the agent is not considered malicious right now because it contains no payload, but it has the potential to generate enough IP traffic to hamper network performance. What has experts most concerned is the ease with which Stumber could be reprogrammed to make it more damaging. The link for this article located at EWeek is no longer available. .
