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...

data securityhacking toolsNSANghia Hoang Pho: 66 Months for Retaining NSA Hacking Tools Legally
Taking work-related documents home to study might get you a promotion and pay raise at some jobs, but not when your employer is the National Security Agency (NSA) – and most certainly not when those materials are classified.. Former NSA employee Nghia Hoang Pho, 68 – a naturalized US citizen who was originally from Vietnam but who’d been living in Ellicott City, Maryland – was sentenced last week to 66 months in prison plus three years of supervised release for willful retention of classified national defense information.

Re "A whistle-blower with global resonance," and "WikiLeaks wasn't wrong," Editorial, July 27 WikiLeaks founder Julian Assange, an Australian hacker, may end up being one of the best things to ever happen to our American democracy.. It is not for politicians and bureaucrats to decide what American citizens and voters need to know. In the last 75 years, we have seen a sharp increase in the use of secrecy laws to cover up illegal activities, corruption and incompetence rather than to protect information that safeguards national security, as originally intended.

Security troubles continue at the Los Alamos National Laboratory, where officials have confirmed that workers recently sent out an undisclosed number of classified e-mails over a nonsecure e-mail system.

Security troubles continue at the Los Alamos National Laboratory, where officials have confirmed that workers recently sent out an undisclosed number of classified e-mails over a nonsecure e-mail system. The new disclosure comes less than two weeks after the New Mexico-based lab announced that two removable computer disks containing classified nuclear weapons data were missing (see story). That incident represents at least the third time since 2000 that storage media containing classified information have been lost in the facility. In the latest incident, lab spokesman Kevin Roark late yesterday confirmed a Los Angeles Times report that the lab recently discovered new incidents of classified information being sent through a nonclassified e-mail system. "We have had occurrences recently, yes," Roark said. "We have had them in the past. It's anticipated we will have them in the future." The incidents, he said, occurred when scientists in the lab, which employs about 12,000 people, incorrectly judged information as being classified or unclassified and sent it without asking for assistance about the contents of their e-mails. The incidents are always promptly reported to the U.S. Department of Energy and other agencies, as required by law, Roark said.

data protectioncybercrimeFBIFBI: Air Gap Security for Classified Information Management
To protect the classified information stored on her desktop computer, Special Agent Nenette Day uses one of the most powerful tools on the planet -- an air gap. Day points to an IBM ThinkPad. . .. To protect the classified information stored on her desktop computer, Special Agent Nenette Day uses one of the most powerful tools on the planet -- an air gap. Day points to an IBM ThinkPad resting on the table behind her desk. "That computer is hooked up to the Internet," she says. "But if you break into it, have a good time: there's no secret work on it." Two meters away on her desk sits Day's other computer -- a gray-and-chrome minitower emblazoned with a red sticker proclaiming that its hard drive is classified SECRET. "This," she says protectively, "holds my e-mail." Day readily talks about the ThinkPad, describing how she got it as part of a big purchase by the Federal Bureau of Investigation (FBI) a few years ago and explaining that it's now somewhat out-of-date. And she happily shows off a collectible action figure -- still in its display box -- a colleague brought back from Belgium. It's a "cyberagent" with a gun in one hand and a laptop computer in the other. But if you let your eyes drift back to that red sticker and try to copy the bold, black words printed on it, Day will throw you out of her office. Day belongs to the FBI's Boston Computer Crime Squad, one of 16 such units located throughout the United States. Each is composed of about 15 agents who investigate all manner of assaults on computers and networks -- everything from lone-hacker to cyberterrorist attacks -- with a dose of international espionage thrown in for good measure. Crimes range from Web site defacements and break-ins to so-called denial-of-service attacks, which prevent legitimate users from accessing targeted networks. .

Knowledge of cryptographic techniques used to belong almost exclusively to governments, which use cryptography to protect political, diplomatic and military secrets against the prying eyes of other governments. Historically, governments took steps to restrict the spread of cryptographic knowledge. Cryptographic activities were conducted in secret departments, some actually called "Black Chambers." Cryptographic texts were suppressed or classified. Knowledge was passed from person to person, from master to apprentice. Trade in cryptographic information or equipment was banned. The field of cryptography was intentionally cloaked in mystery. . Cryptography has been vital in protecting sensitive information throughout history, evolving from ancient ciphers to modern encryption techniques used by governments.
