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...

Gen. Keith Alexander, head of the embattled National Security Agency (NSA), says he is willing to share cyberattack information with the private sector -- an offer seen as a Trojan horse by at least one expert. . On Wednesday, Alexander told attendees of his keynote at the Billington Cybersecurity Summit that the NSA, the FBI, the Department of Homeland Security (DHS) and the CIA are ready to pass information back and forth with a select group of private organizations, provided they get the authorization from Congress.

security advisorycyber incidentcontrol systemsDHS: Rapid Response Required After Stuxnet Cyber Incident
If there's a lesson to be learned from last year's Stuxnet worm, it's that the private sector needs to be able to respond quickly to cyber-emergencies, the head of the U.S. Department of Homeland Security said Monday.. "The key thing we learnt from Stuxnet was the need for rapid response across the private sector," DHS Secretary Janet Napolitano told engineering students at the University of California, Berkeley. "There, we need to increase the rapidity of response, because in that area -- as in several other recent attacks -- we've seen very, very sophisticated, very, very novel ways of attacking. When you're getting at control systems, now you're really talking [about] taking things over, so this is an area of deep concern for us." Although nobody knows who created Stuxnet, many believe that it opened a new chapter in the annals of cybersecurity: the first worm written to destroy factory control systems. On Monday, Iran said it had been hit with a second worm, called Stars,, but security experts aren't sure that it really falls into the same class as Stuxnet.

incident responsefederal securitycybersecurity initiativeKey Priorities for Cybersecurity in the Private Sector by Howard Schmidt
Cybersecurity coordinator Howard Schmidt also announces release of unclassified version of Obama administration's plan for securing government, private industry networks. During a Town Hall meeting session here today, the nation's new cybersecurity czar mapped out his top priorities in the post and provided a glimpse at how the Obama administration might handle security issues with other countries.. In a keynote address earlier in the day, national cybersecurity coordinator Howard Schmidt also announced that the White House was releasing an unclassified version of its plan for securing government and private industry networks -- the so-called Comprehensive National Cybersecurity Initiative, which is now available for download from the White House Website (PDF). Among Schmidt's priorities are the "resilience" of federal government networks and ensuring those networks are properly secured, and ensuring that private-sector partners also have sufficiently secured systems and networks. "The government is not going to secure the private sector," Schmidt said. "[But] we are making sure our [private sector] partners have more security as part of what we're doing." And when it comes to security incident response (IR), he says, these firms have not had a central point of contact. He says he's looking over IR issues for these partners, who want to know who to call when an incident occurs and how to protect their intellectual property. Schmidt says he also wants to ensure state and local governments have law enforcement cyber operations. The link for this article located at Dark Reading is no longer available. .

The Department of Homeland Security and private industry aren't doing enough to exchange information related to threats to critical infrastructure such as IT and telecom networks, the banking system, or the food supply, a report issued Tuesday finds. A Government Accountability Office report offers recommendations to the Department of Homeland Security to improve the protection of national critical infrastructures in 13 sectors. GAO, the research arm of Congress formerly known as the General Accounting Office, suggests developing a plan for information sharing that more clearly describes the responsibilities of DHS and of private-sector information-sharing centers, which were created to pool data on the threats and vulnerabilities most relevant to each critical industry. The report also calls for establishing policies and procedures for agency interaction and the coordination of information sharing. "Sharing information between the federal government and the private sector on incidents, threats, and vulnerabilities continues to be a challenge," the report says.

Businesses will get legal guidelines this year on how to secure their pieces of cyberspace, but lawmakers aren't giving details yet. Forthcoming cybersecurity legislation will be "meaningful regulatory approach to securing private-sector critical infrastructure" says Representative Adam Putnam (R-Florida), who chairs a Congressional subcommittee dealing with cybersecurity. Because many members of Congress don't seem to recognize the potential threat of cyber attacks, the law Putnam has in mind will not be as wide-ranging as the Sarbanes-Oxley Act of 2002, which governs accounting procedures at public companies. "There are a couple of areas where I believe the subcommittee will be drafting bills towards the end of this year that would impact the private sector," Putnam said at an e-government and cybersecurity event here this week.

The Homeland Security Department has proposed rules under which it would protect systems information it receives from the private sector. The proposed rule explicitly applies to hardware and software that makes up critical-infrastructure systems. The government relies on many such systems, such as private voice and data networks, for its daily operations. Companies have been wary of submitting information to the department for several reasons, including the possibility that their competitors could access commercially important data. Some members of Congress and privacy advocates criticized the enacted version of the Homeland Security Act of 2002 as including excessively broad exemptions from the Freedom of Information Act for such information. The proposed rule-making notice, issued Tuesday, is aimed at implementing the Critical Infrastructure Information Act of 2002, which appears in Subtitle B of Title II of the Homeland Security Act.
