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...

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...

Start-up MagiQ Technologies, from Somerville, Massachusetts, has released the first commercial implementation of quantum cryptography, the much-heralded solution to the perfect encryption cipher. Theoretically, encryption ciphers created using quantum physics are unbreakable . While MagiQ Technologies' product, Navajo, isn't itself a quantum device it uses one of the fundamental tenets of quantum theory: Heisenberg's Uncertainty Principle, to create a Quantum Key Distribution (QKD) network. Werner Heisenberg first published his theory in 1927, stating that the more precisely the position of is known, the less precisely the momentum is known. This succinct statement addresses the uncertain relationship between the position and the momentum (mass times velocity) of a subatomic particle, such as an electron, and has profound impact on the development of future information systems. MagiQ's Navajo creates encryption keys that change up to 1,000 times a second to prevent eavesdroppers from deciphering the transmitted data packets. The keys are transmitted over a secure fiber optic link in a stream of polarized photons. If an eavesdropper (or other transmission failure) interrupt the flow of polarized photons, the data is immediately altered, and the encryption system can detect the change. Heisenberg's uncertainty principle comes into play in that even if the eavesdropper only looks at one of the polarized photons, the data stream will be changed, and the intrusion detected. Navajo works with off-the-shelf encryption ciphers, such as the U.S. Government-supported AES (Advanced Encryption Standard). While AES is very secure, the combination of AES and Navajo is theoretically absolutely secure: unbreakable. .

internet securitysecure communicationsencryption solutionEnhancing Internet Security With Open-Source Crypto Key Vault
An open-source hardware project aimed at making the internet "a little bit safer" needs an influx of cash to continue its work.. The Cryptech effort was created following revelations from NSA whistleblower Edward Snowden that the US government and its pals are exploiting standards and weak crypto algorithms to gain access to citizens' private correspondence and documents. In response, a group of engineers decided there needed to be an open-source hardware engine that could provide strong and reliable encryption and decryption for email, plus public-private key cryptography for all sorts of things from digitally signing messages and files to DNSSEC.

PGP has been around since 2002, but the company's roots go back to 1991, when the code base for Pretty Good Privacy (PGP) was developed. Over the years, PGP has become one of the leaders in encryption technologies. The company offers a wide variety of products that help users encrypt data files, e-mails and many other types of data. For the mobile worker and the individual user, PGP Whole Disk Protection is a very good choice for protecting the data on a hard drive.. PGP Whole Disk Encryption offers all of the same basic features as BitLocker and TrueCrypt.

cryptographyhardware securityencryption solutionExploring Trusted Platform Modules for Enhanced Hardware Security
As PC makers gear up to build desktops with hardware security, they face tough choices about how to implement a small but significant cryptography chip crucial to their architecture. That's because chipmakers are offering a bewildering array of options for so-called trusted platform modules, essentially low-cost silicon safes for a digital key. . . .. Atmel, Infineon, National Semiconductor and STMicroelectronics have been selling standalone TPM chips for some time. The chips typically cost less than $10 in volume and can encrypt and decrypt digital certificates and store them in on-board memory. The TPM chips are pivotal in a PC industry initiative to build hardware security into the desktop in tandem with the next major version of Windows dubbed Longhorn. Thus even though the chips are small they ultimately represent a new hundred million unit/year opportunity. Scrambling to get a foothold in that market, Broadcom Corp. announced Tuesday (Feb.17) it has licensed software from Infineon to enable it to build a TPM in its Gbit Ethernet media access controller. Infineon said it is seeking other deals to partner with companies wanting to integrate TPM capabilities into their chips. Meanwhile, National Semiconductor is planning to put a TPM in its Super I/O chips. And at least one vendor is said to be putting a TPM in its media processing silicon for consumer PCs. Eventually, core logic makers may decide to pull the TPM into their x86 chip sets. The link for this article located at Internet Week is no longer available. .

There are more systems in more locations and these are often spread across the world. Many, if not most, IT organizations today, are running lights-out data center operations. There are no management information system (MIS) personnel to oversee the security of the information in those data centers. Many organizations have systems running in remote locations that are not readily accessible to MIS personnel. Some systems may even be running in locations that are under someone else's control - leased space, partner sites, customer sites, etc. Remote storage technologies (e.g. storage area networks) place sensitive, even critical company information, at a vendor's site on vendors' systems where access is controlled by the vendor. Use of "untrusted" networks is the norm. Connections to potentially hostile networks like the Internet are commonplace. Vendors, partners, regulatory agencies and even customers now routinely need access to information that is stored deep within what used to be the security perimeter of the organization. In fact, the need for information to be readily available to those who need it, when they need it, has made the concept of a "secure perimeter" a misnomer. There is no such thing as a truly secure perimeter in today's business environment because sensitive information flows across those boundaries constantly.
