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...

The first-ever social engineering contest at DefCon in Las Vegas last year went way too well: each contestant was able to successfully social-engineer some piece of information, or "flag," out of their targeted company.. Chris Hadnagy, founder of social-engineer.org, which sponsors the Social Engineering Capture The Flag contest, says this year's competition will target more industries including manufacturing, technology, and education, and will include some high-profile companies with aggressive internal security awareness programs that have volunteered as targets. "We have two premiere targets [thus far] that have agreed to work with us and allow [contestants] to call them and social-engineer them," Hadnagy says. "They are willing to put their security awareness programs" up to the challenge publicly, he says. The link for this article located at Dark Reading is no longer available. .

hacker competitioncapture the flagsystem defenseJoin NetWars: Capture The Flag Cyber Challenge for Hackers
Like computers themselves, the Cyber Challenge is simple on the outside and complicated on the inside. The first round of the game began in June, and winners of the earlier games were brought to Washington to compete in NetWars.. In its simplest form, NetWars is an online version of Capture the Flag, with competitors vying to penetrate and take control of target computer systems and then protect them from other intruders. The game begins when a player downloads an image and must find a hidden key within the image. They use that key to enter an online environment and use their knowledge of security vulnerabilities to exploit its system, leaving their name or "handle" in various areas. A moderator threw a series of computer hurdles and roadblocks to further challenge the hackers and test their knowledge about computer vulnerabilities. NetWars differs from other Capture the Flag competitions in that it also rewards hackers for defending computers, said Josh Gimer, 22, a graduate student at Colorado Tech. He likens it more to King of the Hill. The link for this article located at CNN is no longer available. .

Capture the flag might be only a game, but it was serious business at DefCon, the world's largest annual computer hacker convention. For 36 straight hours, eight teams of experienced hackers and serious security professionals played predator and prey as they tried to hack into competitors' networks while defending their own. From my front-row seat as a member of the winning team, Sk3wl of R00t (hacker slang for "School of Root," where "root" refers to gaining administrator access to a system), I got a bird's-eye view of how new - and not so new - attacks could be launched and thwarted. Advertisement: Each qualified team playing the game - organized by a Seattle security community group called the Ghetto Hackers - controlled a pair of Windows machines running a variety of network and Web-based services that were connected to each other and a central scoring mechanism called the Scorebot via a Gigabit Ethernet network. Rest assured, this hacker network was not connected to the Internet. As soon as the doors to the secluded hacker playground disguised as a hotel ballroom were opened at 10 a.m. July 30, the air was tense in this crowded room. The game scenario and the legitimately purchased Windows images were presented to participants two hours before the official noon start time. How would you like to have to lock down two Windows boxes in just two hours as you started to recognize that there were world-class exploit developers in the room - and on your network?

They're a brash, fun-loving lot who revel in their notoriety as two-time champions of Capture the Flag, the Daytona 500 of the computer underground. They also enjoy a measure of renown as hosts of a celebrated bacchanal-a combination trivia contest and Animal House-style beer blast-at Def Con, the annual hacker convention. In their civilian lives, however, these self-taught technophiles make a mint locking down servers and designing hard-to-crack networks. Publicly, Corporate America expresses nothing but scorn for the denizens of this wired-world counterculture. Yet the Ghetto Hackers and their ilk are coveted-if controversial-players in the battle against cybercrime. While most of the major security firms insist on a hacker-free work force, even flaunting their purity in sales pitches, a host of smaller shops are scrambling to enlist the assistance of Eller and his associates. They reason that hacker talent of their high caliber is too precious to ignore. The link for this article located at Business 2.0 is no longer available. .
