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...

proactive securitycyber counterterrorismblack market hackingProactive Strategies for Cybersecurity Against Black Market Hackers
The recent arrest and 17-count indictment against 20-year-old accused hacker and botmaster Jeanson James Ancheta for both using and selling the tools to attack a number of networks, including some within the Defense Department, should be taken as a shot across the bow by anyone who reads this. Ancheta is accused of being part of a new breed of criminal hacker: not just in it for the fame--sure, he's getting his 15 minutes, although it could be more like 50 years--but rather after money. According to the charges against him, Ancheta even managed to collect nearly $60,000 by creating, spreading, and selling bots to the highest bidders. By all accounts, Ancheta is smart and motivated, and there was a market for his black-market guerrilla hacking tactics and tools. How do you stop a smart, motivated attacker from making your life miserable? . To catch a thief, or in this case a cyberterrorist, you have to think like one. IT professionals have been conditioned to think defensively, draping their networks with sensor-studded barbed wire and using firewalls and intrusion-prevention systems to lock down doors and windows around the perimeter. But there's an emerging school of thought that says only a more proactive approach to security can prepare companies for the unexpected.

Most security solutions today are built around attempting to protect the vulnerability of the PC and, or the server, by attempting to keep "bad" things outside of the network security perimeter.

Most security solutions today are built around attempting to protect the vulnerability of the PC and, or the server, by attempting to keep "bad" things outside of the network security perimeter. But, with the changing and disappearing perimeter - security now needs to be intrinsic in every system and for every user. With the changing and disappearing perimeter - the model must change from the black list approach of trying to exclude everything that may be harmful to your network, to a more proactive white list, allowing secure access from anywhere. As evidenced by today's security problems, black list approaches simply do not work! The link for this article located at Bob Johnson is no longer available. . The evolving IT landscape demands a redefinition of security, moving beyond traditional boundaries to embrace intrinsic security and Zero Trust models across networks.

Presidential adviser Richard Clarke today asked the IT industry to support a proposed Internet Operations Center that could provide advance warning of cyberthreats as they spread . "I'd like you all to think about it," he told an audience at a users conference hosted in Washington by Symantec Corp. of Cupertino, Calif. Clarke, head of the president's Critical Infrastructure Protection Board, assured the audience that the center is not a back-door attempt by the government to regulate the Internet. Clarke described the center as a voluntary operation, funded at least partially by the government and probably hosted by a federally funded R&D center, such as the CERT Coordination Center at Carnegie Mellon University or an Energy Department national laboratory.

Executives at Linux security company Cylant say the computer security industry is engaged in a "conspiracy of sorts," or at least a conspiracy of ignorance, in taking a reactive approach to fighting vulnerabilities. Cylant is pitching its CylantSecure server monitoring . . . . Executives at Linux security company Cylant say the computer security industry is engaged in a "conspiracy of sorts," or at least a conspiracy of ignorance, in taking a reactive approach to fighting vulnerabilities. Cylant is pitching its CylantSecure server monitoring product as an alternative to the virus-runs-wild-then-release-patch cycle practiced by most security companies. CylantSecure for Linux, what the company calls a "host-based intrusion detection system," is a real-time monitoring system that immediately notifies the server's sysadmin when something funky is happening that shouldn't be. The technology is based on research into software measurement done by Cylant's chief scientist, John Munson, for large, critical systems like those designed by Jet Propulsion Labs for the U.S. Space Shuttle. The software benchmarks the patterns of execution in the Linux kernel on a server, then determines when those patterns depart from normal. When an attack occurs, notification happens within "milliseconds," says Joel Rothman, president of Cylant. The company has applied for a patent on the process of aggregating the information CylantSecure's sensors pick up and put into a profile that's the server's normal functions. Some of the software is released under the GNU General Public License, and Cylant is a sponsor of the Kernel Instrumentation Project.
