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...

Vendors/Productssecurity breach linux
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...

network securityapplication securitymalware impactImpact of JavaScript Malware on Application and Network Security
All ports were open to the world and practically every application had holes in it. It was like the Wild West. Eventually application security became a big deal as more serious issues were uncovered and more commerce depended upon secure platforms. Network security was next on the scene. It made sense to build a single choke point for all security needs. It was slick because it could see all the packets in transit to and from your servers, and turn off all access to anything that had a known hole in it. Those were the good times. Times have since changed. . Network security, in large part, had a huge role to play in creating the newest attacks. Network administrators rightly told their architects to build applications that could be tunneled over hypertext transfer protocol, while at the same time they would close down all access to any other unnecessary inbound services. Can you see the obvious flaw in their logic here? Even still, aside from the occasional hole in IMAP or BIND, the world of computer security seemed to be calming down quite a bit with the advent of stateful packet inspection and security information management tools. Most of the holes at that time were against the security tools themselves, which most of the hardcore security folks felt was scraping the bottom of the barrel -- the last bunch of entry points to a secured network.

The Sobig worm is to thank for a massive increase in spam e-mail during 2003 and the problem of unsolicited commercial junk e-mail is set to get worse in 2004.. . .. The Sobig worm is to thank for a massive increase in spam e-mail during 2003 and the problem of unsolicited commercial junk e-mail is set to get worse in 2004. That is according to UK-based e-mail filtering company MessageLabs, which claims that there was a 77 percent increase in global spam volumes this year. The firm said that in May, the global spam to e-mail ratio exceeded 50 percent for the first time, with the average ratio for the year being one spam for every 2.5 normal e-mails received. This compared to 1 in 11 during 2002. But possibly the most worrying statistic in the report was a claim that more than two-thirds of all spam was sent through hijacked computers, thanks in part to malware like the Sobig worm which represents a new breed of cyber-pest that blends spamming with viruses. "Sobig.F, the pre-eminent example of this convergence, sought not only to infect a machine and propagate further through mass mailing techniques, but to compromise systems by exploiting open proxies," commented Mark Sunner, chief technology officer at MessageLabs "This backdoor route turns infected PCs into spam relay engines -- causing individual users concern, as well as security breaches and lost bandwidth and productivity for organisations."

Should software companies be more liable for problems caused when software breaks or some malicious outsider breaks it?

Should software companies be more liable for problems caused when software breaks or some malicious outsider breaks it? The National Academy of Sciences, in a security paper released last month, says yes. But I'm not sure our nation's supposedly brightest minds have really thought this out. First, let me make one thing very clear: I don't understand why I have to buy antivirus and security software. Not that I hold anything against the companies that make those products; actually, I think McAfee and--especially--Norton do a pretty good job. BUT IF ALL this software does is protect me against vulnerabilities in Microsoft's operating systems, technologies, and applications, why doesn't Microsoft just give me the protection for free? Or perhaps as a subscription (I know readers hate the word) that includes operating system updates and upgrades as well? The link for this article located at ZDNet is no longer available. .

While the initial version of the worm did little more harm to compromised servers than deface their Web sites, Maiffret said he's among those who fear the impact of an renewed outbreak on Internet traffic could be greater the second time around. The alternate variation of the worm has been described as a "mutated" incarnation of the original, but Maiffret said it doesn't mutate by itself. "How that second version got out is really unclear," he said. "Whether it was the same person who wrote the first one or someone modified (it), we don't know. But it is a little more devious because the way it generates the IP address to attack is random, whereas the first one was in sequence. "Also, the second one doesn't deface Web sites, so it's going to spread more quickly than the first one, and with stealth - which is not a good combination." Maiffret said the total of more than 300,000 infected Web servers during the first outbreak doesn't illustrate the full power of a worm that might have been just getting rolling when it switched to White-House-attack mode late on the 19th.
