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...

data protectionRFID securitywireless securityEnhance Protection With RFID Guardian Firewall For Short-Range Tags
Don't carry RFID? You might be surprised; the short-range ID technology is currently found in everything from US passports to swipeless credit cards to public transit passes to World Cup tickets to car keys to the building access pass for your office building. A few of the digerati even elect to have RFID implants from VeriChip slipped beneath their skin in order to use them as cashless payment systems. . Much of the information on these chips can be read without exotic equipment, assuming an attacker can get within several feet with a concealed RFID reader. Unfortunately, most tags give users no control over when they respond to queries, and they offer no notification, which means that sensitive data could be at risk in public places.

data analysissecurity riskspacket filteringUnderstanding Deep Packet Inspection Risks in Firewall Systems
This paper looks at the evolution of firewall technology towards Deep Packet Inspection, and then discusses some of the security issues with this evolving technology. . Microsoft, Cisco, Checkpoint, Symantec, Nortel, SonicWall, NAI, Juniper/Netscreen, and others, have, in the past eighteen months started manufacturing firewall appliances that implement Deep Packet Inspection (DPI). In general, the DPI engine scrutinizes each packet (including the data payload) as it traverses the firewall, and rejects or allows the packet based upon a ruleset that is implemented by the firewall administrator. The inspection engine implements the ruleset based upon signature-based comparisons, heuristic, statistical, or anomaly-based techniques, or some combination of these. Deep Packet Inspection promises to enhance firewall capabilities by adding the ability to analyze and filter SOAP and other XML messages, dynamically open and close ports for VoIP application traffic, perform in-line AV and spam screening, dynamically proxy IM traffic, eliminate the bevy of attacks against NetBIOS-based services, traffic-shape or do away with the many flavors of P2P traffic (recently shown to account for ~35% of internet traffic), and perform SSL session inspection. Deep Packet Inspection essentially collapses Intrusion Detection (IDS) functionality into the firewall appliance so that both a firewall and an in-line IDS are implemented on the same device. Many of these products have recently been shown to be vulnerable to exploitation of software defects in their DPI inspection engines, however. These data suggest that the addition of these enhanced functions to firewalls may, in fact, weaken, rather that strengthen network perimeter security.

Eleven years later, the Israeli whiz kid who never finished college is co-founder and chief executive of Check Point Software Technologies, one of the most profitable software companies around. How profitable? Well, in the first quarter ending March 31, Check Point's operating margin was a mind-blowing 61%. It made $83.7 million in profit on just $145 million in revenue. Last year, revenues were $425 million, up nearly 100% from the year before. Goldman Sachs projects 2001 revenues will be $650 million. Check Point sells security software, a must-have for any business connecting to the Internet. Despite the gloom surrounding the tech sector, a few silver linings -- companies like Check Point, VeriSign, and Symantec Corp. -- have shown through in the security field. Analysts at Dataquest expect the $2.5 billion market for security software to increase 22% this year. Few companies sell more security software than Check Point. Shwed's company, with offices in Tel Aviv and Silicon Valley, is making its mark in the constant battle with hackers. It produces two key products, firewall software, which is meant to keep hackers out of computer networks, and virtual private network technology, which allows computer users to "tunnel" through the Internet in an encrypted shell that prevents anyone peeping at what they are writing. According to market researcher IDC, Check Point has a 52% share of the firewall market and 41% of the virtual network market.

Secure Computing (NASDAQ: SCUR) today announced the award of four research and development contracts from the Defense Advanced Research Projects Agency (DARPA). The contracts are to develop advanced distributed security technologies to provide safe, secure extranets to the Department of Defense (DoD), government agencies, and for transfer to the commercial marketplace. Secure Computing's contracts total over $6M in funding for research and development through Secure's Advanced Technology Division (ATD). The four contracts that DARPA granted Secure Computing are 1) Autonomic Distributed Firewall, 2) Intrusion Tolerant Server Infrastructure, 3) Releasable Data Products Framework, and 4) Secure High Performance Virtual Private Networks (VPNs). The first three programs are each part of the DARPA Third Generation Security (3GS) initiative that is a coordinated, cooperatively managed suite of programs that are working in concert to develop advanced mechanisms and systems to assure DoD and critical infrastructure systems against cyber attack. Secure Computing will develop enabling technologies that will provide distributed security to individual networks, allow centralized management that is integrated with autonomic response mechanisms, produce passive intrusion tolerance devices, and develop policy management tools. The latter contract is part of Secure Computing's and DARPA's participation in the Federal Small Business Innovative Research (SBIR) program. This project is targeted directly at securing VPNs running over high bandwidth network connections. "Secure Computing recognizes two main objectives for being a research partner with DARPA," said Chris Filo, vice president and general manager of the AdvancedTechnology Division at Secure Computing. "The first benefit is to advance security technology by developing leading-edge solutions that provide a safe, secure DoD infrastructure. Second, DARPA and Secure Computing both recognize the need, and fully support the transfer of these advanced technologies into commercially viable e-business solutions." Consistent with its business strategy, Secure Computing specifically negotiates and retains the right to commercialize technologies developed under government research contracts. As such, they plan to transfer significant portions of the technology developed on these efforts into new and existing product offerings. Secure Computing expects that the first phase of technology transfer from new research and development contracts, to new product offerings, to be delivered in the fourth quarter, 2000. About DARPA The Defense Advanced Research Projects Agency (DARPA) was established in 1958 as the first U.S. response to the Soviet launching of Sputnik. Since that time DARPA's mission has been to assure that the U.S. maintains a lead in applying state-of-the-art technology for military capabilities and to prevent technological surprise from her adversaries. The DARPA organization was as unique as its role, reporting directly to the Secretary of Defense and operating in coordination with, but completely independent of, the military research and development (R&D) establishment. Strong support from the senior Department of Defense (DoD) management has always been essential since DARPA was designed to be an anathema to the conventional military and R&D structure and, in fact, to be a deliberate counterpoint to traditional thinking and approaches. In summary, DARPA's ability to adapt rapidly to changing environments and to seek and embrace opportunities in both technology and in processes, while maintaining the historically proven principles of the Agency, makes DARPA the crown jewel in Defense R&D and a unique R&D organization in the world. About Secure Computing Headquartered in San Jose, California, Secure Computing Corporation is a global leader in providing safe, secure extranets for e-business. Secure Computing solutions provide authentication, authorization, and secure network access. Secure Computing's worldwide partners and customer base are counted among the Fortune 50 in financial services, healthcare, telecom, communications, manufacturing, technology and Internet service providers, as well as some of the largest agencies of the United States government.
