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...

security practicesdatabase securitysecurity challengesTop Five Database Security Risks Identified by IOUG Survey
Though database security best practices have circulated the conference circuit for years now and existing database security tools are now mature, today's typical enterprise is still far behind in shoring up its most sensitive stores of data. . In fact, the Independent Oracle Users Group's (IOUG) recently released data security survey findings are enough to open the eyes of anyone who has ever read news reports about embarrassing data breaches and wondered if his company could be breached next time. Taking a look at the results, it's clear that most organizations today are still running database security by the seats of their pants. The vast majority of organizations do not monitor their databases at all, or do so in an ad hoc fashion. Even more troubling, most enterprises don't even know where their sensitive data resides -- with many administrators admitting in the survey that they are not sure of all of the databases that contain sensitive information.

The IOUG survey reveals critical insights on why database security issues persist in enterprises, primarily due to insufficient employee training and awareness.

traffic analysisethical hackingnetwork analysisThe Importance Of The Sniffer In Securing Network Traffic
One of the most important tools in a security professional's arsenal is the mighty 'sniffer'. Its power is never underestimated, never undervalued. A sniffer is many things to many people. In the right hands it is invaluable, allowing for the analysis of complex traffic passing over the network, in the wrong hands it can be a destructive force, allowing for the capture of confidential or sensitive data as it flows on the wire. . The most common type of network is the Ethernet network. Ethernet was built on the principal that all computers on the same network will share the same 'wire'. As a result, it is potentially possible that any one computer on the network could see all of the traffic on that network, regardless of whether that traffic was destined for it or not. To overcome this possibility, all Ethernet hardware (your network card) is programmed with a 'filter' that instructs it to ignore packets that do not its own MAC address. This has the effect of a single computer only receiving data that has been addressed directly to it, or to the whole network, like broadcast packets.

A graduate student at Dartmouth College wants to tame the FBI's Carnivore surveillance system. Alex Iliev has proposed a way to force anyone who wants to monitor e-mail or Web browsing to follow the rules -- and not snoop on private data that should be off-limits. Iliev's system relies on technology, not Congress or federal judges, to keep Carnivore on a very short leash. Much of the public outcry over Carnivore and similar eavesdropping methods arises because they take a vacuum-cleaner approach, sucking in all the data flowing through a network and then storing only the desired information. But if the snooperware is buggy or if police agencies go beyond what a court order allows, the system will snare far more traffic than it is authorized to retain.

As such, if used by authorized personnel, can prove to be of a great value. But, on the other hand, sniffers represent significant threat to your network, and are very hard to detect. Why a threat, one might wonder? Sniffers do not pose as a direct threat to your data in the common sense of the word, like viruses or malicious code. No, the threat lies in the fact that sniffers are network analyzers designed to monitor network traffic. A high level of risk lies within the abuse of sniffers, due to the fact that an attacker, or a hostile user can gather information that travels through the network, sensitive information like passwords, various confidential information and similiar, stored in plain text or other formats. Usually, the presence of a sniffer on the network can indicate future, more serious attacks against the network. Information gathered through the usage of sniffers can be used for upcoming attacks, further network compromises and can lead to a complete data disclosure and network compromise. So, it's of a great value to recognise the risks posed by network sniffers. The link for this article located at Aleksandar Stancin for Help Net Security is no longer available. .
