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...

cyber threatemail securitybotnetPostini Report Reveals 91% of Emails Classified as Spam Amid Surge
No, you're not imagining things. You have been getting a lot of spam lately. That's because digital miscreants are using contaminated images and stealthy malware to unleash unsolicited email at unprecedented levels, according to new research from San Carlos, Calif.-based Postini Inc. and UK-based Sophos. Attackers use these tactics to hijack computers and turn them into spam relays, often without the user's knowledge. "Bot activity is the major driver here," said Daniel Druker, Postini's executive vice president of marketing. "Bot-infected machines become part of these zombie PC armies that are used to push out spam." . Postini has watched spam levels spike by nearly 60% in the last eight weeks, and Druker said 91% of all email is now spam. Over the past 12 months, the daily volume of spam rose by 120%, he added. Postini monitors 10 million users across 36,000 businesses worldwide. Of that number, the average user gets seven wanted emails a day, while Postini blocks 77 unwanted emails a day. "That's for the average user," he said. "This is an all-time high, and it shows that spammers are increasingly aggressive and sophisticated in their techniques."

The spam flood is rising, contributing to a reduction in the usefulness of e-mail, a market research firm said Wednesday. Unsolicited e-mail from con artists, virus writers and advertisers accounts for 38 percent of the 31 billion e-mails sent each day in North America this year, up from 24 percent in 2002, International Data Corp., said in a report on web mail and spam. In addition, Internet service providers and makers of anti-spam products report that spam represents from 50 percent to 95 percent of all inbound Internet e-mail, IDC said. That's triple the 15 percent to 30 percent levels reported two years ago. The growing spam avalanche has contributed to a reduction in the usefulness of e-mail. Other factors include the increasing cost of storing and managing e-mail and the growing use of instant messaging. The number of spam sent on an average day is 11 billion, compared with 4.5 billion in 2002, IDC said. In comparison, the number of person-to-person emails currently sent each day and in 2002 is 12 billion and 10.5 billion, respectively. Despite these sobering numbers, filtering tools are improving and doing a better job at intercepting spam before it reaches the inboxes of businesses and consumers, IDC analyst Mark Levitt said. Those tools include desktop software, appliances attached to corporate networks and e-mail filtering offered by service providers.

When we finished, he started checking his other messages. All of a sudden, there was DeeDee, a voluptuous vixen in a plunging red tank top and Daisy Duke shorts, smiling sheepishly from the computer screen. I stared at her for a moment, then at my son. He blanched and raised his hands as if he were in a stickup. "I swear! I don't even know the woman!" he said, in Clintonesque denial. There was a tense second or two, until I remembered that the same thing had happened to me countless times when I was innocently checking my e-mail.
