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...

wireless securitynetwork assessmentconfigurationsInvestigating Rogue Access Points and Config Flaws in Retail Wi-Fi Security
For almost 18 months starting in 2005, attackers used wireless networks at TJX and other retail chains to steal credit card data. The vulnerabilities were not an isolated instance: Subsequent research found that about half of all retail outlets in one shopping center had insecure wireless networks.. Today, WiFi security has improved somewhat, but insecurities in installations still remain far too common. Vulnerability assessments of more than two dozen companies found a quarter have rogue wireless access points that were installed by employees, and a third of their wireless networks had misconfigurations that undermined their security, according to wireless security firm AirTight Networks, which conducted the tests. "A rogue AP is a very serious problem if you have it -- an unmanaged, unknown device that is circumventing your defenses," says David King, CEO of AirTight. "All the layers of defense that you worked so hard to put in can be circumvented by a single device that is communicating in the clear."

network securitywifi securitysecurity riskUnderstanding Rogue Access Points and Their Threat to Network Security
A rogue access point is not authorized by an organization's IT department for operation.) Setting up an access point is child's play. In addition to plugging the access point into a power source, all one has to do is connect one end of an Ethernet cable to an available Ethernet port, connect the other end to an access point and voila! A new Wi-Fi WLAN is born. . . .. Although most wireless security solutions target organizations that have deployed wireless networks, there is a class of solutions that target all companies--even those that haven't deployed wireless networks. These solutions detect the existence of rogue access points. (An access point is a transceiver that connects devices on a wireless LAN to the wired infrastructure. A rogue access point is not authorized by an organization's IT department for operation.) Setting up an access point is child's play. In addition to plugging the access point into a power source, all one has to do is connect one end of an Ethernet cable to an available Ethernet port, connect the other end to an access point and voila! A new Wi-Fi WLAN is born. Not all rogue access points are malicious. Until my IT department found out about it and asked me to shut it down, I ran a rogue access point for almost two years (long before Wi-Fi was popular). So early was it in the history of Wi-Fi, that the software for setting up, managing, and securing my Lucent-based 802.11b WLAN was both proprietary and not very user friendly. Knowing that hardly anyone was using Wi-Fi at the time, I didn't bother securing it. Eventually, the company standardized on a single vendor's technology for deploying and securing WLANs and, knowing about my access point through the grapevine, the IT department saw my rogue WLAN for what it was: a back door that bypassed all of the hard work and planning that went into building a secure Wi-Fi network. Nick Miller, CEO of wireless management solution provider Cirond, put the problem in simple terms. "Companies spend thousands upon thousands of dollars andman-hours on network security," said Miller, "and all it takes is a $30 access point to render that investment useless."

Although the emphasis of wireless security measures is primarily on enterprises, threats from unauthorized access points can still arise independently of wireless local area networks..

Enterprises continue to battle the installation of unauthorized, or rogue, wireless LAN access points (AP) on corporate networks by employees who install the increasingly cheap devices unmindful of the security risks, according to speakers here today at Computerworld's Mobile and Wireless . . . . Enterprises continue to battle the installation of unauthorized, or rogue, wireless LAN access points (AP) on corporate networks by employees who install the increasingly cheap devices unmindful of the security risks, according to speakers here today at Computerworld's Mobile and Wireless Conference. Tom Dillon, manager for mobile and wireless at Hilton Hotels Corp. in Beverly Hills, Calif., said the management of a Hilton hotel he recently visited assured him that the property's network had in operation only six authorized WLAN APs. Dillon said he fired up sniffer software and quickly detected 15 APs at the hotel, which he declined to identify. That, he said, clearly illustrates the continued proliferation of rogue APs, which he said IT managers need to battle with strict policies. He also called on companies to institute strong authentication policies to ensure that only authorized users can gain access to wireless networks carrying sensitive business information. That's absolutely necessary, he said, for businesses such as hotels that operate both public and private WLANs in the same space.

By the end of 2002, 30 percent of all enterprises will risk security breaches because they've deployed 802.11b wireless local area networks (WLANs) without proper security, research and advisory firm Gartner, Inc. said Thursday. About 50 percent of all enterprises plan to install WLANs, according to Gartner, but at least 20 percent of large businesses already have "rogue" WLANs in place that were installed by users, not information technology (IT) shops, the firm claims. The users installed the WLANs because they were unwilling to wait for IT personnel to install them. The link for this article located at Internet.com is no longer available. .
