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...

In January 2010, inspectors with the International Atomic Energy Agency visiting the Natanz uranium enrichment plant in Iran noticed that centrifuges used to enrich uranium gas were failing at an unprecedented rate. The cause was a complete mystery. Five months later a seemingly unrelated event occurred. A computer security firm in Belarus was called in to troubleshoot a series of computers in Iran that were crashing and rebooting repeatedly. Again, the cause of the problem was a mystery.

cyber threatsecurity analysisinformation warfareCybersecurity Risks: The Potential for An Electronic Pearl Harbor
Ira Winkler prognosticates on the possibility of a catastrophic online international event. Interesting? For 15 years now, I have been publicly lambasting all of those people who have made their careers, or at least made fleeting news headlines, based on their declaration of an imminent Electronic Pearl Harbor. My disdain is based on several factors, but predominantly the lack of accountability for such statements. . One industry analyst, for example, stated that there will be such an event by the end of 2003. Six years later, I didn't see anyone revisit the utter lack of such an event. However, I now see things developing to the point where there can be a strategic attack on computer infrastructures. The key word is Strategic. Another major issue I have with the people who stake their fame in information warfare is the lack of apparent understanding in the concept of military and geopolitical issues. Specifically, strategy implies long term impacts, generally at least 3-6 months. Tactical attacks have short term impacts. Yes, we have had many tactical attacks against different infrastructures. However, comparing these attacks to Pearl Harbor is insulting. Pearl Harbor was a preemptive strike against the US Pacific Fleet. It significantly degraded the US Naval capability for several years. If the aircraft carriers were in Pearl Harbor as the Japanese expected, it could have been a complete knockout blow. So the question becomes, what can make a computer attack strategic?

Security company Symbiot is about to launch a product that can hit back at hackers and DDoS attacks by lashing out with its own arsenal of tricks, but experts say it may just be a bit too trigger-happy.

Security company Symbiot is about to launch a product that can hit back at hackers and DDoS attacks by lashing out with its own arsenal of tricks, but experts say it may just be a bit too trigger-happy Symbiot, a Texas-based security firm, is preparing to launch a corporate defence system at the end of March that can fight back against distributed denial-of-service (DDoS) and hacker attacks by launching a counter-strike. In advance of the product launch, Symbiot's president, Mike Erwin, and its chief scientist, Paco Nathan, have outlined a set of "rules of engagement for information warfare", which they say should be part of corporate security policy to help companies determine their exact response to an incoming attack. "Until today, security solutions have been totally passive in nature. Merely erecting defensive walls around the perimeter of an enterprise network is not an adequate deterrent," said Erwin, who argues that to have a complete defence in place, offensive tactics must be employed. The company said it bases its theory on the military doctrine of "necessity and proportionality", which means the response to an attack is proportionate to the attack's ferocity. According to the company, a response could range from "profiling and blacklisting upstream providers" or it could be escalated to launch a "distributed denial of service counter-strike". Security experts expressed alarm at the company's plans. Graham Titterington, principal analyst at Ovum, said "such a counterattack would not be regarded as self-defence and would therefore be an attack. It would be illegal in thosejurisdictions where an anti-hacking law is in place." He added that because many hacking and DDoS attacks are launched from hijacked computers, the system would be unlikely to find its real target: "Attacks are often launched from a site that has been hijacked, making it an unwitting and innocent -- although possibly slightly negligent -- party." Richard Starnes, director of incident response at Cable and Wireless Managed Security Services, said he would not employ an "active defence technique" because there are legal and ethical issues involved. Also, he would not be happy about any product "specifically designed to launch attacks" being put into commercial production. Starnes said it would be easy to hit the wrong target and even if it was the right target, there could be collateral damage: "You may be taking out grandma's computer in Birmingham that has got a 100-year-old cookie recipe that has not been backed up. The attack could also knock over a Point of Presence (PoP), so you are not only attacking the target, but also the feeds before them -- this means taking out ISPs, businesses and home users." Jay Heiser, chief analyst at IT risk management company TruSecure, said that he expects the product to have "emotional appeal" to companies that have been targets, but "that is a very bad criterion for choosing risk-reduction measures."

U.S. defense secretary Donald Rumsfeld this week directed the armed service to strip military Web sites of information that could benefit adversaries, citing a terrorist training manual and a year-long review of the Department of Defense's 700-gigabyte Web presence . "An al Qaeda training manual recovered in Afghanistan states: 'Using public sources openly and without resorting to illegal means, it is possible to gather at least 80% of information about the enemy,'" Rumsfeld wrote in a memo electronically circulated throughout the armed services. "One must conclude our enemies access DoD Web sites on a regular basis." The Pentagon has long enjoyed an uneasy relationship with the Web, beginning in 1998 when then-deputy defense secretary John Hamre issued a directive that greatly restricted the type of unclassified information defense sites can put online (classified data is not allowed on the Internet). Following the September 11 terrorist attacks, the Defense Department pulled or pared thousands of additional pages, and established still stricter policies on Web publication.
