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...

data breachcost analysismalicious attackMalicious Attacks Increased Data Breaches To 24% In 2009 Affected Firms
Data breaches at U.S. companies attributed to malicious attacks and botnets doubled from 2008 to 2009 and cost substantially more than breaches caused by human negligence or system glitches, according to a new Ponemon survey to be released on Monday.. The incidence of malicious attacks rose from 12 percent in 2008 to 24 percent last year, according to the 2009 Annual Study: U.S. Cost of a Data Breach survey conducted by the Ponemon Institute and sponsored by PGP Corp. The cost per compromised record involving a criminal act averaged $215, about 40 percent higher than breaches from negligence and 30 percent higher than those from glitches, the survey found. For the first time, companies reported in the survey that data-stealing malware caused their breaches. The average organizational cost of a data breach increased nearly 2 percent to $6.75 million in 2009, while the average cost per compromised record per breach rose only $2 to $204. The most expensive breach in the survey was nearly $31 million and the least expensive was $750,000. Meanwhile, 42 percent of all cases reported in the survey involved mistakes made at third parties, such as outsourcers, and 36 percent of the cases involved lost or stolen laptops or other mobile devices. For the study, 45 U.S. companies from 15 different industries were surveyed. The figures include business costs including expenditures for detection, notification, and response, as well as the economic impact of lost or diminished customer trust and confidence as measured by customer turnover rates.

The increasing trend towards wireless networks may be opening up corporate networks to the risk of malicious hacking, say experts Corporations across the world are opening their doors to hackers when they set up wireless networks -- or when their employees set them up behind their backs. "We came across a company with one of these networks. All their source code, everything was available," said Thubten Comberford of White Hat Technologies, a wireless security firm. "This network was beaconing, 'log onto me'...It basically had its Rolls-Royce parked in the driveway, engine running, with a sign saying 'steal me.'" If you think your company doesn't have to worry, you might want to double-check. According to Gartner Dataquest, about 30 percent of all companies with a computer network have some kind of wireless network, either official or rogue. Furthermore, if the business or cafe next door has a wireless network, you might be in trouble. The link for this article located at ZDNet UK is no longer available. .

Have you ever heard of a Linux vendor that tried to deny a security flaw in their open source product? "A number of Unix vendors have been alerted to a security flaw, but Sun Microsystems is refusing to acknowledge that any problem exists. Six vendors, including IBM, Hewlett-Packard and Sun, have been alerted to a vulnerability that ships with several Unix systems, which could allow a malicious attacker to take control of an affected system. Internet Security Systems (ISS) identified the Unix vulnerability about a month ago, and the company warned that the serious weakness could be found in six Unix vendors' systems. ISS and CERT (Computer Emergency Response Team) issued an advisory about the problem. While Caldera, Compaq and IBM said they had a patch for the problem, HP disagreed on the versions of its Unix flavour that needed the patch.
