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...

Trusted Computer Solutions Inc. has announced that it is developing a product called TCS Trusted Linux, a multilevel-secure version of the Linux operating system. . . .. Trusted Computer Solutions Inc. has announced that it is developing a product called TCS Trusted Linux, a multilevel-secure version of the Linux operating system. Slated for beta testing this fall, the product will consist of software, hardware and firmware designed to enforce a unified security policy. It will be certified under the U.S. Common Criteria Evaluation and Validation Scheme at Evaluation Assurance Level 4. Herndon, Va.-based TCS says the product will also be easier to learn and use than other trusted operating systems. TCS Trusted Linux will ship early next year.

On a normal system, if an attacker gains root or administrator access, he or she can run rampant. Not so on a trusted system -- at least so long as it is properly configured. Another hardened OS is EnGarde Linux, which is sold by Guardian Digital. EnGarde uses the same applications one might find in another Linux distribution, but the approach to building the final product is a bit different. Dave Wreski, CEO of Guardian Digital, told NewsFactor that the average Linux distribution "tries to be all things to all people," which makes it difficult to secure the system.. . ..

Dave Wreski, CEO of Guardian Digital, told NewsFactor that the average Linux distribution "tries to be all things to all people," which makes it difficult to secure the system. But how can you know whether to believe the promises of vendors? This question is less of a dilemma in the case of trusted OSes, because certification standards exist. To be certified as a trusted operating system is no small endeavor, according to Hurley. "The trusted versions ... go through a rather rigorous multiyear process of asserting what the security policies are, documenting them, fault insertions, code review and rather rigorous testing," he said. The most commonly used system, at least in the United States, is the Common Criteria standard. On the other hand, Hurley noted, hardened systems are far less well defined. "There's very little formal theory behind it, less documentation and no testing by an accredited agency." .

Enter the resurrection of the TOS (trusted operating system), a relic from the early '80s developed for military and government security. Considered by many to be too expensive and complicated to implement and maintain, TOSes failed to catch on when introduced to the commercial sector and instead were pigeonholed into the financial industry. With today's corporate Web servers serving as the gateway to mission- critical e-business applications and information, however, IT departments should take a hard look at the new generation of TOSes. View illustration, "Compartmentalization is the key." A TOS is simply a security-hardened version of a standard OS. TOSes come in a variety of flavors, including Sun Solaris, Hewlett-Packard's HP-UX, IBM AIX, Linux, and Microsoft Windows NT. Trusted versions of these operating systems isolate key OS functions into separate compartments, limiting the ability of intruders to access and control critical parts of a computer system, as well as preventing administrators from making inadvertent, harmful changes.

While most Freenix admins are used to the normal concerns of Unix security, there is a higher world of security that has never been touched by Freenixes. The realm of trusted operating systems, long the province only of military and other ultra-secure environments, represents a security level beyond that of all but a few commercial operating systems. . . .. While most Freenix admins are used to the normal concerns of Unix security, there is a higher world of security that has never been touched by Freenixes. The realm of trusted operating systems, long the province only of military and other ultra-secure environments, represents a security level beyond that of all but a few commercial operating systems. Trusted operating systems are not precisely defined, but generally include a number of security enhancements not usually found in Unix. Access control lists (ACLs) allow a file or directorys permissions to be more fine-grained than just owner, group, all. Rather than having just a single root user, limited administration capability can be broken up among a number of administrative accounts ensuring that even an administrator account compromise is non-fatal.
