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...

federal agenciescybersecurity challengespolicy changesUS Government Cybersecurity Struggles Amid White House Role Reductions
Amid a report today that the Trump White House plans to cut the administration's cybersecurity coordinator position altogether, new data shows how US federal government agencies continue to struggle to close security holes in their software.. Politico reported that the administration has eliminated the White House cybersecurity position, which was recently vacated by former head Rob Joyce, who has returned to the National Security Agency. Politico said it had obtained an email to the White House National Security Council staff from John Bolton aide Christine Samuelian: "The role of cyber coordinator will end," in an effort to "streamline authority" in the NSC, which includes two senior cybersecurity directors, she said in the email, according to Politico.

critical infrastructurecybersecurity challengesDHSDHS Appropriations Bill Enhances Cybersecurity Role Amid Ongoing Challenges
A spending bill likely to be passed this month will give the Department of Homeland Security's chief cybersecurity officer more clout but will not solve major issues in how the agency handles its job of protecting the nation's critical infrastructure, security experts said this week. . The criticism comes as an appropriations bill passed by the U.S. House of Representatives is set to be considered by the Senate this month. A separate act that would establish the position of Assistant Secretary for Cybersecurity was added to the spending bill as an amendment. The position would replace the current head of the National Cyber Security Division (NCSD), which was created two years ago to head the agency's efforts to analyze and respond to cybersecurity threats. However, in a report released last week, the U.S. General Accounting Office took the Department of Homeland Security to task, arguing that the federal agency has made progress toward, but not fulfilled, any of its 13 cybersecurity responsibilities. More clout for the chief cybersecurity officer within the DHS could help the situation but will not solve the problems, said David Powner, director of information technology management issues at the GAO and the lead author of the report. "Creating an assistant secretary position will clearly be helpful, but it won't be a silver bullet," Powner said. "Just elevating that position does not solve some of the DHS's challenges."

While other government agencies struggle with their cyber security practices, the Central Intelligence Agency apparently suffers from the opposite problem: too much security -- according to a recent study of the agency's use of information technology . In an unclassified report titled "Failing to Keep Up With the Information Revolution," former CIA officer Bruce Berkowitz -- now a research fellow at Stanford University's Hoover Institution -- found that the agency's intelligence analysts were hobbled by outdated software and cut off from many of the technological advances that workers outside the intelligence community take for granted. Agency e-mail systems are clumsy, and the CIA's search engine is so "primitive" that analysts maintain informal networks of personal contacts within the agency just to track down the information they need to do their job. "A good analyst either knows someone, or 'knows someone who knows someone,' at another office or organization who can get the information they need," wrote Berkowitz.

Not only did it have entail enormous loss, damages and casualties, it also serves as a crucial moment in history. If one looks at December 7, 1941 or September 11, 2001, it is clear that a digital event of the same magnitude would be major socio-political event. If such an event occurred, we wouldn't need a government mouthpiece to tell us about it. Even with the seemingly endless litany of Windows-based worms and viruses plaguing the Internet, nothing has come close to that level of electronic decimation, although Clarke claims is happening on a daily basis. Clarke's use of the term "Digital Pearl Harbor" is purely sensationalist rhetoric. Using it as flippantly and regularly as he does is not only inaccurate, it is also irresponsible and negligent. In the effort to protect homes and business against the perceived threats of cyber-terrorism, White House Cyber-Security Czar, Richard Clarke is engaging in a series of meetings with security industry representatives to discuss the nature of information security, particularly after September 11. Unfortunately, when watching these presentations and testimonies, one starts to wonder how well Clarke truly understands the reality of the world's cyber-security situation - which is a frightening prospect given that he's the top cyber-cop in the nation and has President Bush's ear on the subject.

Like the proverbial Dutch boy with his finger in the dyke to prevent the flood, the guardians of Internet security are vastly unprepared to meet the challenges of defaced Web sites, network intrusions and email viruses, according to one of the country's most notorious hackers. The best the security industry has been able to do, says Robert Lyttle, aka Pimpshiz, is play catch up after the fact. Instead, he said, experts should take the time to develop a rapport and understanding of the very community that spawns these attacks: hackers.

Steven Lynch was first introduced to the joys of hunting down hackers in MIT in 1989. While working in the University's IT department he came across Australia's very own Leftist and Urvile, as they took control of the institutions servers and used them to poke holes in systems on the other side of the world. Phoenix and Electron were eventually tracked down to a flat in Melbourne, but not before Lynch spent countless hours following their clandestine progress through unsuspecting networks. "We became aware they were using machines in the IT department to hack into machines in the US," Lynch said. "They were setting up back doors in the computers they hacked so they could get back in again later." Lynch can't recall what alerted the university's IT department to the suspicious goings on within the university network. Nonetheless when asked by the police to keep an eye on the character's movements, he first had to figure out how to monitor their progress without giving the game away.
