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...

The TJX Companies, a large retailer that operates more than 2,000 retail stores under brands such as Bob. Banking officials in Massachusetts say the TJX breach is behind a recent warning by Visa to banks in Massachusetts, which have contacted customers in recent days and had to reissue thousands of ATM and debit cards. In the end, the hack may affect a wide range of credit card companies and thousands of consumers in America and in countries like the United Kingdom and Ireland, experts say. TJX said it is working with IBM and General Dynamics to investigate the breach, which is believed to have occurred on computer systems that process and store information on customer transactions for T.J. Maxx, Marshalls, HomeGoods and A.J. Wright. Transactions from T.K. Maxx in the United Kingdom and Ireland may have also been exposed in the breach.

Contrary to popular belief, corporate sabotage is among the least likely causes of computer security breaches. According to an April 2002 survey by the Computer Security Institute, sabotage accounted for just 8 percent of system attacks in 2002. Security breaches are more often due to errors by end users or administrators. The inadvertent gaffes are the main culprits for introducing viruses, allowing denial of service attacks, and opening entryways to supposedly secured data. CIOs can reduce, and possibly eliminate, an organization's risk from these errors by creating and implementing a comprehensive set of IT security policies aimed at user behavior. These policies, along with efforts to educate users about how to eliminate security weaknesses, can thwart future vulnerabilities and boost awareness about security issues throughout the enterprise. Defining IT security policies and making them operational is no light task, according to TechRepublic members. A good security policy must address both end users and administrators. On the user side, policies should address how the staff is allowed to make use of computer equipment and applications, according to TechRepublic member William Graham, president of G&G Computing consultancy in Fort Campbell, KY. Graham recommends that end-user policies include the following: The link for this article located at ZDNet is no longer available. .
