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...

P-Cube has announced a new weapon in service providers' ongoing war against hackers and spammers. The Sunnyvale, CA-based IP service control solutions vendor, soon to be owned by Cisco, has enhanced the security features of its Engage v2.1 service application to detect and defend against spam zombies. These attacks are a growing menace for service providers and their subscribers. Hackers and spammers use the attacks to infect host systems with Trojan horses, programs that can distribute more spam or be used in distributed denial of service attacks. Up to 80 per cent of all spam originates from spam zombies, making them a significant cause of storage, bandwidth and productivity loss says P-Cube CEO and president Yuval Shahar. "Augmenting our industry-leading P2P solution, Engage adds security capabilities to our existing service control technology with DDoS and spam protection," Shahar said in a statement. "Our service control technology gives service providers, for the first time, the ability to eliminate the threat posed by legions of spam zombies without disrupting network performance, allowing providers to manage their networks for advanced services delivery."

Today we'll look at how to secure your users' email clients. The reason for employing layers of security at both the server and client level is simple, Grasshopper; do not depend solely on border defenses or the succulent soft underbelly of your network will remain at risk. I'm sure you've heard it a million times -- "Don't use Outlook or Outlook Express." It's darn good advice. Outlook is useful on an intranet, when you need the full scheduling, contacts, document sharing, and other groupware features. For Internet mail -- well, its record speaks for itself. For those who really must use it, see Resources for tips on making Outlook not quite so insecure. If all you need is a POP or IMAP mail client for Windows, Eudora, Pegasus, and Mozilla Mail are excellent choices. They are far less open to exploits, and they use generic mailbox formats instead of the "seekrit" proprietary formats of Outlook/Outlook Express. This makes disaster recovery and importing/exporting a lot easier, because the files can be read as plain text. The link for this article located at CrossNodes is no longer available. .

As spam continues to roll over corporate networks in ever-larger quantities, the cavalry of vendors offering defenses continues to grow as well. No fewer than five vendors are shipping or are about to release new products designed to keep spam from polluting corporate e-mail systems. This week, MailFrontier plans to release a gateway product and upgrades to its client software at the Demo 2003 conference, which is being held in Scottsdale, Ariz., and run by IDG Executive Forums, a division of Network World. Also this week, Sunbelt Software will unveil the server Latest News about Servers edition of its IHateSpam filtering software. Singlefin last week introduced its Local Messaging Switch, a corporate gateway spam filter. Stealth start-up Q-Spam will announce its new name and product in March, and TumbleWeed in April is expected to release a new spam module for its SecureMail product. The spate of products not only highlights the options that companies have for building perimeter defenses against spam, but also reinforces the commonly held notion that spammers remain a step ahead. Spam blocker Postini reports that it filtered more than 600 million spam messages in the last 30 days, more than a 50% jump from just five months ago. .
