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...

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 challengewireless lansurvey resultsSurvey Reveals WLAN Security Hurdles and Employee Demand for Access
The security of wireless LANs (WLANs) is the biggest factor inhibiting their growth in enterprises, but few large enterprises have suffered security breaches, according to a survey released Tuesday by JupiterResearch. . . .. About half the companies responding to the survey said that security was the chief concern preventing growth of WLANs. However, about 84 percent of the companies that have deployed WLANs said they have not suffered from security breaches. Increasing employee productivity -- and requests from end users -- are the primary reason companies are expanding their WLANs, the survey found. "The primary driver behind deployments today is employee demand," Julie Ask, JupiterResearch's research director, said in a statement. "A majority of companies are also recognizing WLANs as a productivity tool for their employees and a more cost effective alternative to wired networks." The survey also found that only six percent of mid-sized and large enterprises offer wireless access for 90 percent or more of their employees. However, about 22 percent of those enterprises said they'd offer access to 90 percent of their employees in 2005. The link for this article located at Mobile Pipeline News is no longer available. .

Securing a wireless Lan remains complex and costly because of immature standards and a lack of interoperability, according to a report by Meta Group. Several approaches have emerged over the past two years that adequately address some of the security concerns related to the original Wired Equivalent Privacy (WEP) encryption protocol used in 802.11b WLans, said Chris Kozup, an analyst at Meta and author of the report. But the different standards and approaches adopted by suppliers make WLan rollouts a major hassle, Kozup said. "Suppliers in general have not been aggressive enough at trying to simplify their solutions," Kozup said. Most are pushing their own agendas with proprietary standards and are "being apathetic in terms of their willingness to push broader adoption of specific standards", he added.

Intro Wireless LANs are popping up here, there and everywhere. Many businesses are implementing wireless LAN segments on their internal LANs because it is easy to setup and obviously there are no wires to run. Wireless allows users with laptops and other mobile devices to roam the enterprise and not have to plug in wherever they go. As part of the process of implementing a wireless network segment on the corporate LAN of the company that I presently work for, I did some research and testing of wireless security. This white paper outlines how hackers are exploiting vulnerabilities in 802.11 wireless LANs and the widely available wireless hacking tools that are used. Too often people think that because the setup of a wireless segment is literally plug and go that everything is functioning properly and securely. Wireless is a virtual playground for hackers, the technology is still quite new, most admins are not anywhere near up to speed on it and security protocols and procedures are still being developed; giving quick-learning hackers the edge. Any wireless access point attached to a network segment is essentially bridging the internal network to the surrounding area directly, without any firewall protection. After only installing one low-budget wireless access point (WAP) I could get access to the LAN anywhere in the shop, the office and in the parking lot!! I don't know how many square feet of shop floor and office space we have, but it isn't small. I was getting 15% connection strength sitting in my car in the parking lot!! Without proper security measures for authentication, any laptop with a wireless card can access the network or stealthy listen in on all network traffic across that access point from any area within the WAPs range.

Ziff Davis Media Inc.'s Feb. 26 eSeminar, "How to Lock Down Wireless LANs," was testament to the interest in and questions about WLANs in the enterprise. The seminar broke registration and attendance records, and attendee questions came in faster than seminar presenters could answer them. Here, then, are answers to some of the most frequently asked questions. For an archived version of the event and more information about eSeminars, go to https://webseminarslive.com/. Q: What management tools can I use to detect rogue wireless LAN access points? A: Vulnerability scanners, usually software products, can use ICMP (Internet Control Message Protocol)-Ping and other well-known network discovery technologies to identify access points. They typically do this by looking for open management ports or ports that at least respond with a signature that reveals the device type.

Since anyone with the software could pry, cable is back in style. The Meteorological Agency and the Tokyo metropolitan government stopped using wireless local area networks (LAN) last week after learning data was wide open to anyone with the will and the right software. Wireless LANs are increasingly popular because they can be introduced or expanded quite simply without cumbersome cables. But when Kazuo Tanabe, a computer consultant in Sabae, Fukui Prefecture, studied LAN emission risks around government office LANs in his own prefecture, then in Tokyo, he found that data transferred on wireless LANs could be intercepted and read by anyone using software freely available on the Web. . Information exchanged via wireless networks might be captured, leading organizations in Tokyo to return to physical connections for enhanced security..

Securing the ether is becoming job No. 1. One approach that's gaining favor is to use security gateways to lasso groups of access points. These boxes are available from a handful of start-ups, including Bluesocket, Cranite Systems, Fortress Technologies, ReefEdge and Vernier Networks. As a single sentry, the wireless security gateway might provide a firewall and support for authentication and encryption. Some products, such as those from Bluesocket and ReefEdge, can manage wireless bandwidth by enforcing quality-of-service restrictions on bandwidth use or application types. It's not only the all-in-one aspect of these security appliances that appeals to early adopters. Many organizations say the gateways complement existing security resources such as VPNs and directories used to authenticate users of Ethernet LANs and enterprise applications.

When the Pentagon--no small potential customer--cracked down recently on the installation of wireless LANs, the industry sat up and took notice. Why? The inherent vulnerabilities of the technology. If you simply go to the nearest computer dealer and buy a $99 access point and plug it in, your wireless link will be insecure. But vendors are bringing out commercial equipment to make it easier to overcome the security problems that plague wireless LANs. They are splitting access points into two parts so that the 2.4- and 5.0-Gigahertz radio signals can be showered anywhere, but a second component behind the corporate firewall will arbitrate the access or movement of data.
