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...

security toolsLinux kerneleBPFImproving Security in Cloud Native Systems With eBPF Observability
Security providers are using eBPF for observability to prevent attacks, detect and remediate high-priority vulnerabilities (and to distinguish between severe and less severe vulnerabilities), to detect suspicious activity and other uses. . The eBPF (extended Berkeley packet filter) is being used to solve several security issues in cloud native environments, beyond its initial use of network monitoring. Its penetration, extending from within the Linux kernel (and on Windows to a lesser extent), across runtimes in a network or environment, makes it an “enhancement” to the Linux operating system, according to Gartner analyst Simon Richard in Gartner’s “ Hype Cycle for Compute 2023 .” While running specific instruction sets from within the kernel, eBPF allows organizations to add features to Linux without changing kernel source code or requiring kernel modules, Richard writes. Specific to security, eBPF offers a very detailed way of monitoring and provides traces for monitoring different potentially suspicious system activities and codes. This all lends itself to the speed of processing or just-in-time processing within its tunnel. A key aspect is that security providers are using eBPF for observability to prevent attacks, detect and remediate high-priority vulnerabilities (and to distinguish between severe and less severe vulnerabilities), to detect suspicious activity and other uses. This extension, of course, includes analyzing incidents and giving and receiving alerts for vulnerabilities and incidents. , and analyzing or finding potentially risky vulnerabilities and attack vectors. It is the observability aspect that leverages eBPF in order to monitor and detect suspicious activity and to help determine which vulnerabilities have the potential to be exploited. . eBPF is revolutionizing defense strategies in cloud-native environments by facilitating comprehensive observation and risk assessment.. eBPF Security, Cloud Native Threats, Observability Tools, LinuxKernel Enhancements. .

security monitoringcontainer securityeBPFExploring eBPF Technology for Container Security Monitoring
With eBPF monitoring container activity from the kernel layer, many of the challenges associated with observability in the cloud are solved. . eBPF (enhanced Berkeley Packet Filter) is a Linux kernel technology that offers a powerful and stable method of observing the Linux kernel. It’s like having a VM in the kernel that can safely run hooks (i.e. programs) for filtering data like network events, system calls, packets, and more. eBPF is being adopted at scale for its guaranteed stability, the ability to work directly in the kernel, and potential savings when factoring in the compute process for gathering telemetry on Linux servers and containers. eBPF is rapidly gaining traction in cloud native applications , especially in places where traditional security monitoring doesn’t work. It’s eBPF is well suited for uses in distributed and container-based environments, including Kubernetes. The core benefits of the technology include speed and performance, a low level of intrusiveness, security, unified tracing, and programmability. It is safer than previous options because of the way it sees inside processes without introducing the risk of crashing the application or modifying the kernel in any way. eBPF is a preferred alternative to the audited framework because it is less invasive and more efficient. By monitoring from the kernel layer, many of the challenges associated with observability in the cloud are solved. You can enjoy deeper visibility, more context, and more accuracy in your data. If you have an interest in increasing your container security, it’s worth learning more about what eBPF can do for you. . eBPF (extended Berkeley Packet Filter) is a Linux kernel innovation that significantly improves security and observability in containerized environments.. eBPF, Container Security, Kernel Monitoring, Telemetry Solutions. .

application developmentsecurity advancementsKubernetesAnticipated Breakthroughs in Kubernetes Security for 2022
While it’s come a long way over the past year, Kubernetes security has not yet reached maturity. But judging from the level of investment in 2021 into technologies for securing Kubernetes — the now-dominant container orchestration platform — enterprises can expect major advancements in the area during the coming year. . Originally launched as an open source project by Google in 2014 and now under the domain of the Cloud Native Computing Foundation, Kubernetes automates numerous processes involved in the management and deployment of containerized applications. Developers have increasingly gravitated to the platform, which helps to support a modern approach to application development using a microservices architecture. . The field of cloud-native security has matured notably, yet complete sophistication is still forthcoming as developments are anticipated in 2022..

runtime protectionmalware riskscontainer securityExploring Container Security Risks: Prepare for Emerging Threats
Container technology adoption has experienced a rapid upward surge over the past few years. But now that it has gained a serious foothold in the enterprise, questions are beginning to arise about container security. Perhaps the fundamental question is, just how secure are containers? . Most seem to think containers are secure; that they somehow contain magical powers when it comes to malware protection. But Dan Walsh, a Senior Engineer at Red Hat , says IT managers need to stop assuming that Docker and the Linux kernel protect you from malware. Unfortunately, few appear to have heeded that warning. The 2021 Cloud Native Security Survey by Aqua Security found only 3% of respondents recognized that a container, in and of itself, was not a security boundary. Only 24% of respondents had plans in place to deploy the necessary building blocks for runtime security. . A common belief is that cloud services are invulnerable, yet specialists warn about flaws and misunderstandings in cloud security practices..
