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...

The head of developer advocacy for Paypal and Braintree, Jonathan Leblanc, has an idea that will seem absurd to some, innovative to others and terrifying to still others. The executive of the multi-billion dollar eBay subsidiary suggests in a recent presentation called . fingerprint passwordsHis premise is that user behavior has historically proven the system of password authentication to be inadequate. Users always seem to opt for easy passwords that can be cracked by brute force with ease, and this is not a problem that will lessen with the advancement of technology.

As a security technologist, I worry that if we don't fully understand these technologies and the new sorts of vulnerabilities they bring, we may be trading a flawed technology for an even worse one. Electronic locks are vulnerable to attack, often in new and surprising ways. Start with keypads, more and more common on house doors. These have the benefit that you don't have to carry a physical key around, but there's the problem that you can't give someone the key for a day and then take it away when that day is over. . As such, the security decays over time -- the longer the keypad is in use, the more people know how to get in. More complicated electronic keypads have a variety of options for dealing with this, but electronic keypads work only when the power is on, and battery-powered locks have their own failure modes. Plus, far too many people never bother to change the default entry code. Keypads have other security failures, as well. I regularly see keypads where four of the 10 buttons are more worn than the other six. They're worn from use, of course, and instead of 10,000 possible entry codes, I now have to try only 24. Fingerprint readers are another technology, but there are many known security problems with those. And there are operational problems, too: They're hard to use in the cold or with sweaty hands; and leaving a key with a neighbor to let the plumber in starts having a spy-versus-spy feel.

bioinformaticsnetwork efficiencysecurity standardsInnovative Fingerprint Solutions Reduce Storage Needs and Boost Security
New technology for matching fingerprints for security purposes is proving about as reliable but much more efficient than traditional techniques, according to a new study by the National Institute of Standards and Technology. NIST studied the use of "minutiae templates," which are mathematical representations of full-blown fingerprint images that are seen as being much easier for vendors of biometric security systems to exchange with each other. The study involved use of a new standard for minutiae data that makes data exchange simpler than when proprietary techniques for converting fingerprint images to minutiae data. . The templates are also a fraction of the size of a fingerprint image, reducing the need for storage on smart cards and other such devices. Fourteen vendors of fingerprint technologies participated in the Minutiae Interoperability Exchange Test (MINEX), which was sponsored by the U.S. Department of Homeland Security and the Department of Justice. The standards group said that performance depended on how many fingerprints from a person were being matched, with systems using two index fingers accurate more than 98% of the time.

Biometrics authentication technology should be a promising means to confirm a cardholder's authenticity. With a Linux-based radio frequency (RF) personalizer that reads and writes in memory, the administrator can set various parameters of the smart security controller, such as real-time clock, personal identification number (PIN) option, alarm options and reader delays. Biometric security Relevant Products/Services from Verisign -- Free E-Commerce Start-up Kit with fingerprint matching involves protecting results -- a user's template, fingerprint images, a fingerprint's features, and a user's finger. The simplest design solution for a client considering finger-print matching is to embed all functions and data in tamper-resistant smart cards. . However, smart cards with a fingerprint scanner and high-powered processor for feature extraction and image processing may not be practical because of the cost of distributing the card to each user. Biometrics authentication technology should be a promising means to confirm a cardholder's authenticity. With a Linux-based radio frequency (RF) personalizer that reads and writes in memory, the administrator can set various parameters of the smart security controller, such as real-time clock, personal identification number (PIN) option, alarm options and reader delays. This protocol can upload card transaction data saved in the reader memory. It can also access key sets and other operational data to the reader. A biometric Latest News about biometric template is an encrypted hash of the actual biometric itself. You can effectively combine smart cards and biometrics for personal authentication over the open-source network. The combination is a two-step authentication in which you authenticate the smart card based on a public key infrastructure Relevant Products/Services from Sybase ASE Linux Express Edition – FREE (PKI). Cardholder authentication occurs by using the template stored in the smart card based on the biometrics verification. Execution of theverification must occur in the card for security purposes. The RF smart card and card reader/writer handle payment transactions for public transportation systems. Security features of these contactless cards include encrypted RF transmission, mutual authentication, and security keys. The card has up to 16 separate sectors, which you can configure as purses or for general data storage Relevant Products/Services from IBM eServer xSeries Systems. You typically use the first sector as a directory for the rest of the card, leaving 15 segments available for data or purses. You can store up to 15 different applications on an RF smart card, and when you use unique keys for each sector, applications are separate and secure from one another.

An MP who volunteered to take part in the UK ID card trials says the iris scanner used is uncomfortable and made his eyes water. Poor chap, you're probably thinking, but not exactly a tragedy. However, this isn't just a whinge. The water in his eyes actually stopped the scanner from working, and it seems long eyelashes and hard contact lenses could fox it too. So we're going to have a system that is derailed by a few tears and fluttering eyelashes? Roland Sables, the man in charge of the trial, said that he was expecting a failure rate of about seven per cent. Most of these failures, he argued, would be caused by problems with camera positioning, although others "are due to eye malformations, watery eyes and long eyelashes in a small percentage [of cases]". Sables said that so far the iris scanner had failed to match people with their details in just four per cent of cases. Scale that up to the UK population and you've got nearly 2.5m people who won't be correctly identified. The link for this article located at TheRegister is no longer available. .

As we rely on computers for tasks like handling money and keeping secrets safe, it has become increasingly important to give our desktops, laptops and PDAs the means to know for sure who they are dealing with. The classic solution is to lock up the data, and give the user a cryptographic key. The main challenge to improving this type of security is to make it more difficult to steal or reconstruct the keys, but at the same time make it easier for legitimate users to access computing resources. Researchers from Lucent Technologies' Bell Labs are tapping the individuality of the human voice to generate unique cryptographic keys for computer users. Under the researchers' scheme, a user speaks a password, and the system listens for both the correct word and the correct voice.

Recent reports of simple ways to circumvent biometric Latest News about biometric security systems -- such as the "gummy finger" tactic, which involves a homemade gelatin mold on which a fingerprint is imprinted -- have been embarrassing for the biometrics industry. However, analysts said such breaches will force vendors to improve their technology, which often is used to restrict access to companies' most valuable data. Analysts also stressed the need for layers of security, noting that no security measure can be effective on its own. Indeed, biometric security vendors typically market their products as part of a mix. According to experts, when combined with other security measures, biometrics can pave the way for adoption of safeguards that often are resisted by corporations. .
