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...

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...

cyber threatsdata privacyinternet monitoringExploring NSA Backdoors: Risks Posed to Data Privacy and Security
We already know the NSA wants to eavesdrop on the Internet. It has secret agreements with telcos to get direct access to bulk Internet traffic. It has massive systems like TUMULT, TURMOIL, and TURBULENCE to sift through it all. And it can identify ciphertext -- encrypted information -- and figure out which programs could have created it. . But what the NSA wants is to be able to read that encrypted information in as close to real-time as possible. It wants backdoors, just like the cybercriminals and less benevolent governments do.

To her fellow students, Hu Yingying appears to be a typical undergraduate, plain of dress, quick with a smile and perhaps possessed of a little extra spring in her step, but otherwise decidedly ordinary. And for Hu, in her second year at Shanghai Normal University, coming across as ordinary is just fine, given the parallel life she leads. For several hours each week she repairs to a little-known on-campus office crammed with computers, where she logs on, unsuspected by other students, to help police her university's Internet forums. .

law enforcementsurveillancecommercial productsFBI's Internet Surveillance Shift: Carnivore to Commercial Products
FBI surveillance experts have put their once-controversial Carnivore Internet surveillance tool out to pasture, preferring instead to use commercial products to eavesdrop on network traffic, according to documents released Friday. . Two reports to Congress obtained by the Washington-based Electronic Privacy Information Center under the Freedom of Information Act reveal that the FBI didn't use Carnivore, or its rebranded version "DCS-1000," at all during the 2002 and 2003 fiscal years. Instead, the bureau turned to unnamed commercially-available products to conduct Internet surveillance thirteen times in criminal investigations in that period. Carnivore became a hot topic among civil liberations, some network operators and many lawmakers in 2000, when an ISP's legal challenge brought the surveillance tool's existence to light. One controversy revolved around the FBI's legally-murky use of the device to obtain e-mail headers and other information without a wiretap warrant -- an issue Congress resolved by explicitly legalizing the practice in the 2001 USA PATRIOT Act.

national securitydata privacyinternet monitoringBush Administration's Internet Monitoring Proposal Raises Privacy Issues
The Bush administration is planning to propose requiring Internet service providers to help build a centralized system to enable broad monitoring of the Internet and, potentially, surveillance of its users. . .. The Bush administration is planning to propose requiring Internet service providers to help build a centralized system to enable broad monitoring of the Internet and, potentially, surveillance of its users . The proposal is part of a final version of a report, "The National Strategy to Secure Cyberspace," set for release early next year, according to several people who have been briefed on the report. It is a component of the effort to increase national security after the Sept. 11 attacks. The President's Critical Infrastructure Protection Board is preparing the report, and it is intended to create public and private cooperation to regulate and defend the national computer networks, not only from everyday hazards like viruses but also from terrorist attack. Ultimately the report is intended to provide an Internet strategy for the new Department of Homeland Security. Such a proposal, which would be subject to Congressional and regulatory approval, would be a technical challenge because the Internet has thousands of independent service providers, from garage operations to giant corporations like American Online, AT&T, Microsoft and Worldcom. The report does not detail specific operational requirements, locations for the centralized system or costs, people who were briefed on the document said. While the proposal is meant to gauge the overall state of the worldwide network, some officials of Internet companies who have been briefed on the proposal say they worry that such a system could be used to cross the indistinct border between broad monitoring and wiretap. Stewart Baker, a Washington lawyer who represents some of the nation's largest Internet providers, said, "Internet service providers are concerned about the privacy implications of this as well as liability," since providing access tolive feeds of network activity could be interpreted as a wiretap or as the "pen register" and "trap and trace" systems used on phones without a judicial order. Mr. Baker said the issue would need to be resolved before the proposal could move forward. Tiffany Olson, the deputy chief of staff for the President's Critical Infrastructure Protection Board, said yesterday that the proposal, which includes a national network operations center, was still in flux. She said the proposed methods did not necessarily require gathering data that would allow monitoring at an individual user level. But the need for a large-scale operations center is real, Ms. Olson said, because Internet service providers and security companies and other online companies only have a view of the part of the Internet that is under their control. "We don't have anybody that is able to look at the entire picture," she said. "When something is happening, we don't know it's happening until it's too late." The government report was first released in draft form in September, and described the monitoring center, but it suggested it would likely be controlled by industry. The current draft sets the stage for the government to have a leadership role. The new proposal is labeled in the report as an "early-warning center" that the board says is required to offer early detection of Internet-based attacks as well as defense against viruses and worms. But Internet service providers argue that its data-monitoring functions could be used to track the activities of individuals using the network. An official with a major data services company who has been briefed on several aspects of the government's plans said it was hard to see how such capabilities could be provided to government without the potential for real-time monitoring, even of individuals. "Part of monitoring the Internet and doing real-time analysis is to be able to track incidents while they are occurring," the official said. The official compared the system to Carnivore, theInternet wiretap system used by the F.B.I., saying: "Am I analogizing this to Carnivore? Absolutely. But in fact, it's 10 times worse. Carnivore was working on much smaller feeds and could not scale. This is looking at the whole Internet." One former federal Internet security official cautioned against drawing conclusions from the information that is available so far about the Securing Cyberspace report's conclusions. Michael Vatis, the founding director of the National Critical Infrastructure Protection Center and now the director of the Institute for Security Technology Studies at Dartmouth, said it was common for proposals to be cast in the worst possible light before anything is actually known about the technology that will be used or the legal framework within which it will function. "You get a firestorm created before anybody knows what, concretely, is being proposed," Mr. Vatis said. A technology that is deployed without the proper legal controls "could be used to violate privacy," he said, and should be considered carefully. But at the other end of the spectrum of reaction, Mr. Vatis warned, "You end up without technology that could be very useful to combat terrorism, information warfare or some other harmful act." .

While the Great Wall no longer deters would-be invaders from entering China, experts meeting in Washington on Monday said the Chinese government continues to maintain a nearly rock-solid cyberwall. At a panel discussion held by the Congressional-Executive Commission on China, experts warned that China has recently improved its censorship technology -- much of which is provided by U.S. companies. The panel also claimed that China now employs some 30,000 "Internet police" to monitor its citizens, and that is has increased arrests of dissidents and journalists posting illegal content on the Internet.

The National Communications System is in the early stages of a Global Early Warning Information System (GEWIS) pilot project in which government and industry will examine the health and topology of the Internet . The pilot project will assess how well critical areas of the Internet are performing worldwide, and then use that data to notify government, industry or U.S. allies of an impending cyberattack or possible disturbance, said Brenton Greene, deputy manager of NCS. Those indicators will include looking at the performance of selected government and industry e-commerce sites, as well as tools to identify and detect worms or denial of service attacks, he said, adding that the pilot project (also called the Global Cyber Early Warning Information System) will not be ready for launch until next year.

In the seven months since the passage of a sweeping law to combat terrorism, Internet and telecommunications companies have seen a surge in law enforcement requests to snoop on subscribers. Privacy advocates fear that expanded police power under the Patriot Act -- combined with lax oversight and increased cooperation between the government and private sector phone network and Internet gatekeepers -- may be stomping on civil liberties. The new laws do not apply just to terrorism but to other crimes as well. "The trend up to September 11 was for more privacy protection, greater procedural safeguards, more sunshine on the process and more notice," said Al Gidari, a Seattle privacy lawyer who represents Internet and telecoms companies. "I now see all those things tied up in a box with a little bow on them and forgotten about in the corner," he said. Law enforcers say they need stepped-up electronic surveillance to keep up with sophisticated criminals, stressing that such efforts are targeted -- they're not trolling every server for e-mails mentioning Osama bin Laden.

President Bush signed legislation Friday that expands the ability to tap telephones and track Internet usage in the hunt for terrorists, new powers that drew praise from law enforcement officials and concern from civil libertarians. The bill, known as the USA Patriot Act, gives federal authorities much wider latitude in monitoring Internet usage and expands the way such data is shared among different agencies. "Today, we take an essential step in defeating terrorism while protecting the constitutional rights of all Americans," Bush said during a signing ceremony. The House of Representatives passed the bill by a vote of 357-66 on Wednesday, and the Senate on Thursday approved the measure 98-1. Attorney General John Ashcroft vowed Thursday to use the new powers to track down suspected terrorists relentlessly. The link for this article located at News.com is no longer available. .
