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...

digital forensicsdata preservationevidence gatheringEffective Data Preservation Methods in Digital Forensics Analysis
Computer forensics involves the preservation, identification, extraction, documentation and interpretation of computer data. It is often more of an art than a science, but as in any discipline, computer forensic specialists follow clear, well-defined methodologies and procedures, and flexibility is expected and encouraged when encountering the unusual. It is unfortunate that computer forensics is sometimes misunderstood as being somehow different from other types of investigations. . . .. Computer forensics involves the preservation, identification, extraction, documentation and interpretation of computer data. It is often more of an art than a science, but as in any discipline, computer forensic specialists follow clear, well-defined methodologies and procedures, and flexibility is expected and encouraged when encountering the unusual. It is unfortunate that computer forensics is sometimes misunderstood as being somehow different from other types of investigations. For instance, if you were investigating a murder that took place in Times Square, you would photograph the scene, look for evidence, and take samples of the crime scene, including control samples to compare to the evidence. The collection of evidence proceeds similarly in a computer investigation, but for some reason, some people want to recreate the entire system, be it a standalone PC, a server with a terabyte RAID system, or even an entire network. Nobody expects the prosecution to rebuild Times Square in the courtroom, but that is often the expectation in a computer crime case. Admittedly, digital data can be highly volatile. General unfamiliarity not only with computer forensics, but also with computers themselves, makes this field a highly challenging one, but this book can help you prepare for it.

computer investigationcybercrimedigital evidenceInside the DoD Crime Lab: Analyzing Cyber Evidence for Justice
Digital evidence comes in all shapes and sizes: pallets full of computers, a hard drive with an AK-47 bullet hole in it, audio tapes fished out of the ocean, mangled floppies, garbled 911 calls. Whenever U.S. government agencies investigating a crime or a cybercrime has digital evidence that's too difficult to analyze, they send it to the Department of Defense computer forensics lab. . . .. Digital evidence comes in all shapes and sizes: pallets full of computers, a hard drive with an AK-47 bullet hole in it, audio tapes fished out of the ocean, mangled floppies, garbled 911 calls. Whenever U.S. government agencies investigating a crime or a cybercrime has digital evidence that's too difficult to analyze, they send it to the Department of Defense computer forensics lab. The evidence can arrive in a military vehicle, via FedEx or through the U.S. Postal Service. However it gets there, it's accepted at the loading dock of an unmarked commercial building on the outskirts of Baltimore. It's then logged and sent to an evidence custodian, who inventories, tags and stores it in a locked cage. Network World was invited into the Defense Computer Forensics Lab (DCFL) for an inside look at how computer investigators at the cutting edge are using digital evidence to help solve crimes. The purpose of the lab is to analyze evidence gathered at crime scenes involving the military. Whatever crimes occur in the civilian world, you also see in the military. It could be homicide, child pornography, identity theft, counterfeiting, misconduct, terrorism, espionage, contractor fraud or misuse of government property. With these crimes, there's often digital evidence in cell phones, pagers, PDAs, geo-mapping systems, digital cameras, cockpit recording systems and anything else with flash memory or ROM. "We estimate that 95% of criminals leave digital evidence at the scene," says Donald Flynn, attorney adviser for the Defense Department Cyber Crime Center, which houses the DCFL. That evidence must be able to stand up in court,particularly now that judges and attorneys are becoming savvy enough to start asking questions about the integrity of digital evidence. The DCFL addresses this through rigorous training and advanced tools such as certified, high-capacity extraction and imaging processes and tools. Inside the lab My tour guide at the high-security lab pushed a button at the double-door entryway into the lab that triggered blue ceiling lights, which blinked incessantly to alert technicians that unclassified visitors were on the premises. The lab includes your standard office cubicles, but every cube is outfitted with state-of-the-art processors, multi-system server stacks and 42-inch flat-screen monitors. "Some of the evidence comes in on pallets - cases full of servers, CPUs, RAID disk arrays, floppy diskettes, Palm Pilots, digital cameras," says special agent Bob Renko, director of operations for the lab. "We've even gotten evidence in buckets of water - for example, video tapes recovered from jets crashing into the sea during training exercises."
