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...

security concernsip networktechnology deploymentIP Network Security Concerns and Executives' Deployment Plans
Despite high levels of concern about the security of IP networks, companies are planning to press ahead and roll out the technology regardless, according to research from the Economist Intelligence Unit (EIU). . Over two thirds of the 236 global chief executives and chief information officers questioned said that network security is a major concern when it comes to switching to a totally IP network. But the same proportion were planning to deploy the technology anyway. Security concerns rank more highly than worries over the cost of network installations, and wireless network protection is seen as a key risk area. Viruses and worms are still seen as the main problems, but the respondents see these and most other threats decreasing over the next two years. However, they expect targeted attacks from internal staff, either espionage or sabotage, to rise. The link for this article located at VNUNet is no longer available. .

The problem with having the signal broadcast though is that it is difficult to contain where that signal may travel.

With wireless access points proliferating into hotels, airports and convention centers, there is a real need for security enhancements that will make the corporate world more confident in Wi-Fi technology, says Yankee Group wireless/mobile services director Roberta Wiggins. "Enterprises are currently hesitant on extending employee access into the public Wi-Fi arena," she told NewsFactor. At least part of that hesitancy is due to the low expectations engendered by the notoriously flawed WEP (wired equivalent privacy) security standard. Reacting to a barrage of criticism, the Wi-Fi Alliance now is promoting the use of a new technology called "WPA," or Wi-Fi protected access. But does this new security measure have what it takes to foil the network-busting activities of hackers? Some wireless-security experts are suggesting -- albeit, cautiously -- that it might. "One of the fundamental problems with WEP is that it used static keys that could be identified and compromised by a hacker," Wi-Fi Alliance managing director Frank D. Hanzlik told NewsFactor. However, WPA "uses a dynamic key structure under which the key is always changing. This makes it very, very difficult to compromise. That was the fundamental problem, and that's what WPA addresses," he said. . As wireless access points become common in places like hotels and airports, the effectiveness of Wi-Fi Protected Access (WPA) against hacking threats is crucial to examine.

This is often easier said than done. A wireless network is more difficult to secure than a typical wired network because, while a wired network has a limited number of fixed physical points of access, a wireless network can be used at any point within the range of the antennas. Despite the inherent difficulties, properly protecting your wireless networking system is key in safeguarding your system from serious security problems. If you deploy an insecure wireless network, it could result in a loss of service or in the use of your network as a launching pad for attacks against other networks. To help you close these security holes, make sure your networking staff follows these six quick wireless networking tips. The first step in implementing a closed wireless access point is to place the access point's antenna in such a way that it limits how far the signal can reach beyond the coverage area. Don't place the antenna near a window, as the glass does not block the signal. Ideally, your antenna will be placed in the center of the area you want covered, with as little signal leaking outside the walls as possible. Of course, it's next to impossible to completely control this, so other measures need to be taken as well. The link for this article located at ZDNet is no longer available. . Enhance your wireless network security with these effective strategies: change default credentials, enable WPA3, hide SSID, use MAC filtering, and more.
