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...

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...

cybercrimesecurity threatslaw enforcementImpact Of Anonymous And LulzSec Arrests On Cybersecurity Challenges
The FBI and Scotland Yard should be praised in their ability to track down, identify and arrest members of the related hacking organizations Anonymous and LulzSec. The cyber-sleuthing they did is not easy. When you have to do it well enough for the arrest to hold up in court, it. While the arrest of 12 members of the Anonymous hacking group, as well as two of the reputed six-member LulzSec team, may have taken these specific people off the street, the fact remains there is a limitless supply of people who want to break into computer networks, the higher the profile the better. Anonymous has already threatened a retaliatory attack on the FBI for the arrests. Whether they go through with the threats and whether the attacks, if attempted, are successful remains a mystery until it happens. The link for this article located at eWeek is no longer available. .

cyber threatsnational defensesecurity challengesExploring Richard Clarke's Legacy in Cybersecurity and National Defense
In all the recent ruckus about the strained relationship between the Federal Government and the computer security community, it is fitting to now remember Richard Clarke. He's been grabbing headlines lately on the strength of a book claiming that he warned Bush about Al Queda but was ignored, a charge that might strike even Bush-haters as odd, given Clarke's illustrious record of causing nothing to be done about terrorism for all the time he was the head terrorism czar. What has he been really up to, instead? Hawking the yet-to-materialize threat of cyber-terrorism, on the theory that real terrorists want to virus and spam us to submission. This is the Terrorism --> Cyberterrorism Czar, folks, and the best excuse the Feds have for trying to tell us how to be secure. . . .. The retirement of Richard Clarke is appropriate to the reality of the war on terror. Years ago, Clarke bet his national security career on the idea that electronic war was going to be real war. He lost, because as al Qaeda and Iraq have shown, real action is still of the blood and guts kind. In happier times prior to 9/11, Clarke -- as Bill Clinton's counter-terror point man in the National Security Council -- devoted great effort to convincing national movers and shakers that cyberattack was the coming thing. While ostensibly involved in preparations for bioterrorism and trying to sound alarms about Osama bin Laden, Clarke was most often seen in the news predicting ways in which electronic attacks were going to change everything and rewrite the calculus of conflict. September 11 spoiled the fun, though, and electronic attack was shoved onto the back-burner in favor of special operations men calling in B-52 precision air strikes on Taliban losers. One-hundred fifty-thousand U.S. soldiers on station outside Iraq make it perfectly clear that cyberspace is only a trivial distraction. Saddam will not be brought down by people stealing his e-mail or his generals being spammed with exhortations to surrender. Clarke's career in subsequentpresidential administrations was a barometer of the recession of the belief that cyberspace would be a front effector in national security affairs. After being part of the NSC, Clarke was dismissed to Special Advisor for Cyberspace Security on October 9th in a ceremony led by National Security Advisor Condoleeza Rice and new homeland security guru Tom Ridge. If it was an advance, it was one to the rear -- a pure demotion. Instead of combating terrorists, Clarke would be left to wrestle with corporate America over computer security, a match he would lose by pinfall. Ridding the world of bad guys and ensuring homeland safety was a job for CIA wet affairsmen, the FBI, the heavy bomb wing out of Whiteman Air Force Base -- anyone but marshals in cyberspace. Information "Sharing" and Cruise Missiles The Slammer virus gave Clarke one last mild hurrah with the media. But nationally, Slammer was a minor inconvenience compared to relentless cold weather in the east and the call up of the reserves. But with his retirement, Clarke's career accomplishments should be noted. In 1986, as a State Department bureaucrat with pull, he came up with a plan to battle terrorism and subvert Muammar Qaddafi by having SR-71s produce sonic booms over Libya. This was to be accompanied by rafts washing onto the sands of Tripoli, the aim of which was to create the illusion of a coming attack. When this nonsense was revealed, it created embarrassment for the Reagan administration and was buried. The link for this article located at SecurityFocus is no longer available. .

JANUARY 16, 2004 ( REUTERS ) - Computer virus attacks cost global businesses an estimated $55 billion in damages in 2003, a sum that would rise this year, said Trend Micro Inc., the world's third-largest antivirus software maker. Companies lost roughly $20 billion to $30 billion in 2002 from the virus attacks, up from about $13 billion in 2001, according to various industry estimates. "The economic and financial impact of virus attacks will continue to climb in 2004," Lionel Phang, Trend Micro's Managing Director told Reuters in an interview. He did not have a forecast for the year. Spam threats and network viruses will likely become more prevalent in 2004, he said. "The spam threat will increase exponentially, and will become the hideouts for viruses and hacking programs trying to gain an entry into the network," he added. One attack every month Last year, there was almost one major virus attack every month, including the well-known Slammer worm, which shut down Internet service providers in South Korea, disrupted plane schedules and knocked out automatic teller machines in January.

What would happen if open source software were banned in the Defense Department? A recent study conducted by Mitre Corp. for DOD posed that hypothetical question and found this answer: The department's cybersecurity capabilities would be crippled and other areas would be severely impacted. Mitre Corp. was asked to develop a listing of open-source software applications at DOD and to collect representative examples of how those applications are being used. Over a two-week period, an e-mailed survey identified 115 applications and 251 examples of use, and Mitre's report acknowledged that actual use could be "tens of thousands of times larger than the number of examples identified." To help analyze the data, the hypothetical question was posed: What would happen if open-source software were banned at DOD? Version 1.2 of the report, "Use of Free and Open Source Software (FOSS) in the U.S. Department of Defense," was released Sept. 20 to the Defense Information Systems Agency (DISA), and found that open-source software applications are most important in infrastructure support, software development, security and research.
