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 Unix operating system has so many descendants and variations that organizations navigating the maze of choices can quickly become disoriented.

The Unix operating system has so many descendants and variations that organizations navigating the maze of choices can quickly become disoriented. Many of these projects were launched to offer operating systems unencumbered by the commercial and proprietary licenses tied to the original AT&T UNIX. One of the first open source major branches to develop this way is the BSD family, which has since spawned a number of descendants, including FreeBSD, NetBSD, and OpenBSD. Apple's Mac OS X is also based on a BSD operating system known as Darwin. People often use the term "family" to describe the lineage of Unix operating systems, and the word is an apt metaphor. Think of each operating system as being a distinct personality -- the erudite grandfather, the know-it-all cousin, the doting mother. Like a family, they have many traits and capabilities in common and also differ in their strengths and weaknesses. Therefore, when trying to decide on an operating system, bear in mind that it is not so much a case that one Unix operating system is "better" than another, but which is the best choice for a given environment.

Net users can expect a growth in attacks of Unix systems next year, not to mention more Blaster-style worms capable of infecting computers without using email. The growing trend of virus writers and spammers apparently working together (evidenced by worms like Sobig and Mimail) can also be expected to continue into 2004, according to security firm Sophos, which predict little let up in mass-mailing viruses next year. However, the UK-based anti-virus and anti-spam firm predicted that viruses infecting mobile devices will once again fail to pose much of a threat in 2004. . Individuals utilizing Unix systems should prepare for an uptick in cyber threats in the coming year, along with an increase in Blaster-like vulnerabilities..

A new Internet worm designed to attack a common flaw in Unix systems has been confirmed dead, but security experts are warning that the self-propagating worm could be the next Code Red.

A new Internet worm designed to attack a common flaw in Unix systems has been confirmed dead, but security experts are warning that the self-propagating worm could be the next Code Red. The X.C worm exploits a newly discovered hole in the telnet service that is run on most Unix systems. Antivirus companies are concerned that crackers will have learned from the success of the Code Red worm and its variants, and will be encouraged by the length of time that it takes system administrators to patch machines against publicized vulnerabilities. "This is going to go along the same lines as Code Red, as virus writers will know that a lot of machines will be vulnerable," said Mark Read, systems security analyst for computer security company MIS Corporate Defence Solutions. "This is definitely the way forward with viruses, as it removes the need for humans to double click on attachments in order for the worm to spread, and instead looks for servers that have not been patched."

Traditionally, BIND has been the nameserver of choice when doing name service on a Unix system. Like many of its close relatives, such as sendmail, it was designed at a time when the internet wasn't even known as the internet, and security wasn't a concern. This has caused more than a few problems over the years, and many point to the age of its codebase, and lack of designed-in security as part of the problem. The link for this article located at Security Focus is no longer available. . Considering alternatives to BIND, djbdns offers a secure and simple name service solution, focusing on safety, easier configuration, and performance.
