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...

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...

data protectionnetwork protocolswireless encryptionWi-Fi Security Perspectives: Assessing Future Enhancements and Challenges
While the past of Wi-Fi has been plagued with security problems the economics are such that many players in the IT market want to see the insecure WEP replaced with something more robust. While nothing in the future is certain, it seem a given that Wi-Fi will overcome its adolescent growing pains and mature into a reasonably secure and easy to deploy method of networking. . . .. While the growth of 802.11b wireless networking has been explosive, problems with security of data being transmitted have plagued the technology almost since its conception. Still in spite of its drawbacks 802.11b has some compelling reasons for its deployment, both by the consumer and in the enterprise. Those reasons include its low cost, its ease of deployment and the tremendous convenience that wireless networking offers. As anyone knows who remembers the old Party Line telephone system, some times lack of good privacy can be lived with. Risk in general is discussed as well as basic ways to mitigate the risk. While Wireless Fidelity's (Wi-Fi) main security algorithm Wireless Encryption Protocol or WEP as it is commonly referred to remains relatively easy to crack, it is still better than nothing. This and other counter measures are discussed from basic residential wireless setups to more advanced ways the enterprise environment might consider for deploying wireless for transmission of important corporate data. While data security, confidentiality, integrity and user or access point authorization has left much to be desired in Wi-Fi's past, the future of Wi-Fi seems, at least at present to be brighter. Perhaps the main reason for this has been Wi-Fi's tremendous growth, which makes many of IT's main players want to see it succeed. WPA, 802.11X and other technologies have support of such industry giants as Microsoft and Cisco. So while secure wireless computing is still not a reality, it is a technology that merits close watch for the enterprise. The link for this article located at ebcvg.com is no longer available. .

The biggest security risks for "Wi-Fi" wireless Internet networks are that users sometimes fail to turn on their encryption software. But even the responsible ones who use the encryption program -- Wired Equivalent Privacy -- aren't immune to malicious attacks. . . . . The biggest security risks for "Wi-Fi" wireless Internet networks are that users sometimes fail to turn on their encryption software. But even the responsible ones who use the encryption program -- Wired Equivalent Privacy -- aren't immune to malicious attacks. A growing trend on the streets of Manhattan are WarDrivers who break into wireless networks for fun. A professional hacker or anyone with significant programming knowledge can hack through WEP and even steal data off the network. Unlike WEP, WPA utilizes a series of mathematical algorithms to authenticate users who are logging onto the network and to prevent anyone without valid credentials from entering. But if hackers send "two failed forgeries," or packets of unauthorized data during a one-second period, the system assumes it is under attack, said Intel network security architect Jesse Walker in a white paper on 802.11 security. "WEP provides a level of security too low for me to take seriously," said Niels Ferguson, a cryptography consultant in Amsterdam who helped come up with an alternative encryption to WEP.

Demand is growing for desktop and wireless encryption but Network Associates (NAI) says it has no plans to resurrect its Pretty Good Privacy (PGP) range, despite requests from users. The IT security firm announced it was suspending the development of its PGP series of products last October. In March of this year, the company confirmed the software would enter 'maintenance mode' until a buyer was found. Despite reported discussions with several third-party firms, Infosecnews understands that no buyer has been found, with the result that the product range remains on ice. The PGP line includes PGP Corporate Desktop, PGPmail, PGPdisk, PGPwireless and PGPKeyserver, none of which will be developed further under NAI ownership. Commenting on the product development freeze, Jennifer Keavney, NAI's vice president, said that the situation remains the same. Despite the firm's lack of updates, other companies, most notably ArticSoft, CryptoHeaven and Standard Networks, are developing alternatives. Infosecnews notes that current PGP users can turn to programs like Information Security Corporation (ISC)'s trade-up offer, under which PGP users can buy a copy of the firm's multi-platform file encryption tool SecretAgent at a discount. According to Tom Venn, the firm's president, Network Associates' dissolution of its PGP operation has led to many organizations actively seeking a more lasting option for their file encryption needs. On top of the commercial offerings, there are now a number of free 'open source' alternatives, such as Gnu Privacy Guard. PGP's original creator, Phil Zimmerman, and former senior fellow at Network Associates, has called on his former employer to release the PGP source code if they have no intention of sustaining it. "I would stronglyprefer PGP to be open source, compared with the current scenario, because right now it's locked in intellectual property prison and no one can get at it," he said. . The need for both wired and untethered encryption is on the upswing, yet PGP languishes, gradually ceding its position to newer options..

The attack was described in a recent paper by Fluhrer, Mantin, and Shamir. With our implementation, and permission of the network administrator, we were able to recover the 128 bit secret key used in a production network, with a passive attack. The WEP standard uses RC4 IVs improperly, and the attack exploits this design failure. This paper describes the attack, how we implemented it, and some optimizations to make the attack more efficient. We conclude that 802.11 WEP is totally insecure, and we provide some recommendations.
