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...

cybersecuritytraffic analysisevasion researchFuture Worms Evasion Research and Impact on Internet Sensors
Future worms could evade a network of early-warning sensors hidden across the Internet unless countermeasures are taken, according to new research. In a pair of papers presented at the Usenix Security Symposium here Thursday, computer scientists said would-be attackers can locate such sensors, which act as trip wires that detect unusual activity. That would permit nefarious activities to take place without detection. . Internet sensor networks, such as the University of Michigan's Internet Motion Sensor and the SANS Internet Storm Center, are groups of machines that monitor traffic across active networks and chunks of unused IP space. The sensor networks generate and publish statistical reports that permit an analyst to track the traffic, sniff out malicious activity and seek ways to combat it. Just as surveillance cameras are sometimes hidden, the locations of the Internet sensors are kept secret. "If the set of sensors is known, a malicious attacker could avoid the sensors entirely or could overwhelm the sensors with errant data," a team of computer scientists from the University of Wisconsin wrote in its award-winning paper titled "Mapping Internet Sensors with Probe Response Attacks." But the Wisconsin researchers discovered that the sensor maps furnish just enough information for someone to create an algorithm that can map the location of the sensors "even with reasonable constraint on bandwidth and resources," John Bethencourt, one of the paper's authors, said in his presentation..

network securitymalwarecountermeasuresUnderstanding Spyware Risks and Protection for Enterprise Networks
Spyware is challenging spam and viruses for the top spot on IT worry lists. Spyware poses considerable threats and risks to enterprise networks and remediation and countermeasures are now being regarded as critical to network security. . How Spyware Threatens Enterprises Spyware is defined as covertly installed software that hijacks web browsers, invades Internet user privacy, displays unsolicited and offensive advertising, and impedes PC performance. The most commonly cited spyware issues worrying enterprise IT staff are loss of productivity and increased helpdesk costs; liability associated with privacy violations; intellectual property theft, information and premature disclosure; and loss of credibility and damage to brand.

Citing an "arms race" in the ongoing spam wars, AT&T defended its patenting of a technology to thwart antispam filters. The patent, awarded to AT&T on Nov. 4, describes a "system and method for counteracting message filtering." The patent details a way to trick filters that compare digital messages to known pieces of spam, altering each message so that no two are exactly the same. "In this way, spam countermeasures based upon duplicate detection schemes are foiled," according to the patent. AT&T's patent wins approval as spam and software patents separately preoccupy the Internet. Opponents, pointing to patent-infringement judgments like that won by Eolas Technologies at Microsoft's expense, say software patents have created a siege mentality in the industry. And the spam problem has resulted in a host of proposed solutions in the software, standards and legislative arenas. .

I am presently working on creating a taxonomy of information assurance, based on the three aspects of: Security services Information states Security countermeasures These three aspects of Information Assurance (IA) were highlighted by John McCumber [1] as well as a team of West Point researchers [2] as a component of works that define an integrated approach to security. Within the next 6 months, I would like to create a taxonomy that graphically depicts the relationships of these three aspects. My intent is that this taxonomy could be used by the academic community, industry, and government in improving the precision of communication used in discussing information assurance/security topics. I have searched the Internet widely for a taxonomy of IA, but I have not found anything that is sufficiently detailed for application with real world problems. I am posting my initial results here in hopes that an open collaboration process (much like the open source software movement) will yield a useful tool for the security community to use in addressing information assurance issues.

Buffer overflow problems always have been associated with security vulnerabilities. In the past, lots of security breaches have occurred due to buffer overflow. This article attempts to explain what buffer overflow is, how it can be exploited and what countermeasures can be taken to avoid it. Knowledge of C or any other high level language is essential to this discussion. Basic knowledge of process memory layout is useful, but not necessary. Also, all the discussions are based on Linux running on x86 platform. The basic concepts of buffer overflow, however, are the same no matter what platform and operating system is used.

There's a war brewing in cyberspace. Make that a Netwar, so dubbed in Countering the New Terrorism, a book published last year by The RAND Corp., a Santa Monica, Calif.-based nonprofit research group formed during World War II. It'll be a long time before remote-controlled robots fight battles to keep intruders out of office buildings (though unconfirmed reports circulated among security newsgroups in September did claim that a company in Thailand has invented a gun-toting robot directed through a remote-controlled camera). But many players, including the government, RAND and Winn Schwartau, a security analyst in Seminole, Fla., say this information war is already upon us. And in his Internet survival book, Cybershock, Schwartau claims that some private corporations are already launching military-style counterattacks to protect their interests.
