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...

encryptionsecuritycryptographyGareth Williams: The Enigmatic Code-Breaker and His Unresolved Fate
On Friday, in the Bethel Methodist Chapel in Angelsey, the funeral was held of Gareth Williams. In life, he was a mathematician and an encryption specialist so highly regarded that he was seconded from GCHQ in Cheltenham to work at MI6 in London. . In death, he is an enigma, an infuriating mystery for most of us, a deeply upsetting puzzle to his parents; for, though his body is now laid to rest, the questions about the bizarre way he met his end show no sign of being buried. Yesterday brought another theory, something this saga has attracted as a September orchard does wasps. The facts are these. Gareth Williams was 31, studied mathematics at Cambridge, was recruited by the government's listening and monitoring operation in Gloucestershire, and was lent for a year to MI6. He moved to London last September, lived in a five-storey security services safe house at 36 Alderney Street, Pimlico, worked on matters such as computer security involving the City, and led, as far as police can tell, a rather introverted existence The link for this article located at The Independent is no longer available. .

encryptioncryptographypublic keyUnderstanding Elliptic Curve Cryptography and Mathematical Concepts
Elliptic Curve Cryptography (ECC) is a public key cryptography. In public key cryptography each user or the device taking part in the communication generally have a pair of keys, a public key and a private key, and a set of operations associated with the keys to do the cryptographic operations. Only the particular user knows the private key whereas the public key is distributed to all users taking part in the communication. Some public key algorithm may require a set of predefined constants to be known by all the devices taking part in the communication. ?eDomain parameters?f in ECC is an example of such constants. Public key cryptography, unlike private key cryptography, does not require any shared secret between the communicating parties but it is much slower than the private key cryptography. . The mathematical operations of ECC is defined over the elliptic curve y2 = x3 + ax + b, where 4a3 + 27b2 ? The link for this article located at Info Sec Writers is no longer available. .

Mathematician Phil Carmody, who in March of this year managed to encode the DeCSS source in a prime number, has upped the ante by producing a prime number which represents an executable version of the banned CSS descrambler. Legally this is all a bit squishy, as the DMCA forbids us to make available an access-control circumvention device. All well and good, not that we've tended to care what the DMCA allows or forbids; but this item is also the fruit of mathematical research which the public certainly has a right to see. It's a fine legal paradox for the recording industry to chew on. Is research illegal because it could in some tiny degree weaken their monopoly over the production and distribution of digital media? Or does the public's right to be informed of academic developments make a circumvention device legal when it also exhibits academic value?

Mathematics enthusiast Leo de Velez who claims to have discovered a faster way of decoding RSA encryption believes that his findings are solid since nobody is still using his formula of 2^X = 1 mod N where N is given as the public key, find X. Rivest noted that any technique that can find a multiplicative inverse of e modulo lambda(n) can be used to factor n. "So if your approach finds such exponents somehow, then you also have a factoring algorithm, not just an algorithm to break RSA," Rivest said.
